Episode 3: The Importance of Variance in the Headcount Planning Process
Podcast Overview
-
Eric Guidice:
Okay, episode three, Headcount Experts, Chris Mannion, Eric Guidice. Today we're talking about last year's plan year and using it to inform this year's plan year. We've both done it and I'm interested to hear an overview. What's your general vibe? What are you looking for from last year when you're entering workforce planning season? Just big picture so that you can make the most accurate plan year for, in this case, 2026.Chris Mannion:
Yeah, I think you want to go in with not just a plan for 2026. You want to say, what was our plan for 2025 and what actually happened? Because that's the baseline for planning. It's not the aspirational plan for 2026, but what was our aspirational plan for 2025 and then what was reality. If you have that data ready to go and you’ve done that analysis before you get into the 2026 planning meeting, then you know what to expect. You can do some red teaming when you get in there and say, what happens if this changes, what happens if that changes? Go in with the expectation that whatever you plan is a basis for change. By the end of Q1, that plan is probably going to change. How are you expecting things to manifest over the course of the year and what are you trying to achieve at the end of it?Eric Guidice:
A big thing for me going into the meeting is finding allies among executive peers. The planning process is some people's full job, so they are biased toward saying this is the correct plan, but real outcomes are that plans change. Finding people who understand that helps you navigate what I call assumption accuracy. For every hundred requisitions that you think are going to happen in a year, a different amount will happen. If you do a hundred, congratulations, you're the exception. But a different amount will happen. I’m looking for folks who understand what variance looks like. The simplest is attrition. People can change their minds and split roles, change compensation, change titles, change levels. Those variances create different demands on different teams, whether it's org structure, the HR team, recruiting capacity, the structure of the individual team, or the production of that team. Finding the person who's going to be my ally in those changes helps build credibility in the meeting for how I establish the boundaries for what's possible for the next year. There are a couple of things I look at that I want to get into, but what are the key things you're looking at from 2025 to inform 2026? What do you look for?Chris Mannion:
I like that ally framework. That's more qualitative compared to going straight for the data. Understanding from those allies, and for those in the room for the first time, what was the expectation for the previous year, what was the plan when we did the 2025 headcount plan season, what happened in Q1 and Q2 that changed that plan, and how did we respond. What were the big events over the year, the highs and lows, and how could we have predicted that ahead of time if we go back 12 months. Using that, what does 2026 look like. What potential issues are we going to face. How could we predict not when they are going to happen, but what our response should be. How can we adapt the plan and make sure we have the right structures in place so we don't succumb to last-minute swinging of levers, but bake in scenarios and assumptions so we maintain agility. We don't want to be doing an emergency plan at the end of Q2 because budget came in above expectation, the board is asking why we're overspending, and we have to make drastic changes that affect the business.Eric Guidice:
You're getting into Headcount365 benefits like real-time financial tracking. You never want to get to a surprise change in the headcount plan because of budget, but that's to the side. What you mentioned combines two key metrics I look at when building the future plan. First is the plan change rate. What is the raw variance of headcount from what you thought it would be in 2025 to what it actually is in 2025. It's a gross variance of new hires, attrition, and attrition backfill, so you have an idea of actual headcount movement and how far away it is from plan. My success for building future plans is did I reduce the plan change rate. If it grows, the plan was less accurate. If it shrinks, it was more accurate. It's a broad climate measurement of how headcount planning is going.The next thing is capacity vs. demand actuals, which is what happened to create that plan change rate. I tried to put this together in spreadsheets for years. It's difficult because you have to track timeline-based history of every role. If a role changes from one thing to the next, you have to line item that story, then categorize it. It's hard to run pivots on longer-form stories. I built a capacity vs. demand actuals report in Headcount365. You can replicate it in a spreadsheet, which you can download at Unicorn Talent. Capacity vs. demand actuals says: we had a plan change rate. Why.
Chris Mannion:
The why is more important than the what, because you’re almost never going to see exactly the same scenario manifest year over year. But the why, the fundamental shift in the market or the internal talent dynamic or hiring velocity, will repeat to some degree. Understanding all the different whys and what we do about them, then baking that into the plan, is important. When you think about not just how many people we need and how many by org, but what that does to org design. Is the structure right for the company. What could change that will throw that org design out of whack, or throw our comp plan out of whack, or any base assumption. If you lay out assumptions in a document upfront and say these are the assumptions going into 2026, you can build models to use those assumptions as inputs and make changes quickly. What happens if revenue is 10 percent above expectation or 10 percent below, what happens if attrition spikes, what happens if we shift to a different market. Instead of roles for a market we know well, we enter a new market because that’s where demand pull is coming from. Understanding those assumptions is good business planning anyway, but especially for headcount planning where the timeline to change is long and the cost implication is huge if you have to make a change.Eric Guidice:
There is variance we’ll know about from our own process, then there’s business variance that may not be present in a recruiting or finance system, like sales data, fundraising data, or macroeconomic changes like tariffs that change how your business operates. There will be external inputs to the process, and internal inputs of change that create variance. Did the recruiters perform. Did the hiring managers perform. If recruiters had capacity and you missed a goal, the other input is whether the hiring manager performed. You have the performance of what you thought would happen, and you have company variance. You have natural attrition, comp changes, a new competitor in the market. There are many reasons why. Start broad with plan change rate to say what is the difference. Use capacity vs. demand actuals to say what is the motion of headcount that created that plan change rate. Then you have the why, which is research beyond the headcount plan and into the overall business. Tying it back to allyship: when you can articulate those three things to a peer business leader, they’re going to be on your side. There’s a beginning-of-fiscal-year hubris in planning. Everyone thinks the recruiting team is operating at max capacity. Set the difference between what is possible or what actually will happen and what the team expects to happen using allyship and those three stats. That’s tremendously helpful heading into a 2026 workforce planning session.Chris Mannion:
That hubris is a good point. We’ve mentioned second-order effects of planning in the past. If you assume business will be strong, you expect increased revenue and increased demand for R&D and go-to-market talent. You increase spend there and build recruiting capacity. You did everything perfectly in your plan and then you go to execute. Unpredictable events happen. Competitors think the same thing. They start poaching your recruiters because they’re fully trained. Your best recruiters get poached for higher salaries, which means you need to backfill recruiting capacity, which delays hiring timelines. More experienced go-to-market and R&D folks get poached by those recruiters. You have outflow of talent and your inflow becomes harder. How do you think through that second-order impact. I’ve seen that manifest.Eric Guidice:
I won’t say the company, but I’ve been sent a cease and desist for poaching when I was an internal recruiter. Your sales leader is the one to empathize with most. Recruiters need ramp. The gap between recruiter attrition and recruiter production is the hiring process and the ramp process. If you plan on paper that a recruiter in a seat means recruiter production, and you’re not factoring ramp, that could be a line item of variance. It goes two ways. One, recruiting gets only what they need to produce and you’re at redline all the time. The cost of not hiring someone is downtime and ramp time and lost production. You pay for it in lost revenue from not hiring on time, or you save money from the optics that you’re not paying that recruiter or those hires from being late. The other side is you allow a recruiting leader to staff capacity above what we think is possible and they can use that additional firepower to do projects that improve brand, experience, candidate experience, hiring manager experience. When a recruiter leaves, the cost is that recruiters stop doing projects and swarm on the lost productivity until you get someone in place. You pay upfront for more recruiters. The business pays either way. It’s just at different times and in different ways. A sales leader would understand that. It ties into headcount planning for 2026. If you could predict seller attrition, you could start recruiting so that by the time they’re offered and ramped, that ramped seller comes into fruition as you expect attrition. I wrote about forecasting attrition. A big benefit of moving to software from spreadsheets is looking at the relationship between variance. What did you think sales would do, recruiting would do, any production department would do. How did attrition impact it. How predictable is that attrition based on HRIS data or other info you can port into one system. Draw a regression line across attrition to predict when you need replacement production so you’re not always filling valleys. Core variance I look for in 2025 for 2026 is attrition and its impact on production and revenue. Once you can predict that, you can make a business case for additional spend. It drives credibility and the recruiting leader’s strategy in the executive meeting.Chris Mannion:
Two points to drill into. One is the capacity of the recruiting team and the importance of not operating at full capacity, which is counterintuitive when we talk about efficiency. Two is the quality of producer and the ability to respond to unforeseen demand or circumstances. Those go hand in hand. Lower capacity gives more ability to flex. Advising a CEO on talent funnels and keeping pipeline always on, there are a few concepts. Setup time is long. It takes ramp to build up. The primary reason I advised him was quality of hire. Every person on a senior leadership team is a one-of-one. If someone underperforms or leaves, you have a gap. You don’t want to make suboptimal decisions and keep someone underperforming because you don’t have a pipeline. The way that feeds back into capacity is if recruiters operate at 70 or 80 percent capacity, which I generally recommend, that other 20 to 30 percent is spent building relationships and talent community. Stay in touch with people who will be a good fit in the future. If a VP needs to be exited, you already have a slate of five or six candidates you can bring next week. Maybe that pipeline doesn’t move quickly, but it’s quicker than starting from zero. There’s a lot of value there. Not hammering too much on second-order effects, the topic here is the planning process and how capacity planning for 2026 impacts your ability to execute when you bake in assumptions and what-if scenarios. I’ve seen it both ways. A company is left with a huge gap that damages productivity, and others where someone can be exited quickly and backfilled because of pipeline, and the company goes on to success.Eric Guidice:
We’ll do a deep dive on capacity later in the season. The points you’re making are the second order of how accurate is the plan, what is the predicted variance, and how do I build a staff that can handle it. We call it variance, but it’s what’s going to happen. If for every 100 hires you make 120, and you’ve done that for the last two or three years, you need to staff to 120 even if the plan is only 100. Your job as a recruiting leader is to convince people why you need to staff for those additional 20, balancing the cost risk of replacing a recruiter or not. It’s all connected. The thing I like to focus on for this year’s plan for next year’s accuracy is a deep dive into assumptions. I think of assumptions in two major groups. One is what is going to happen to the business. Two is what is going to happen within the business.What happens to the business includes macroeconomic changes like tariffs. There are companies in headcount plans trying to figure out what that does to where they hire, what they hire, how many, and pricing. Whether you’re planning to fundraise, worried about economics, depending on where you are in your growth curve or competition, these are all inputs to your headcount plan. Being able to see macro changes year over year helps you assume what’s going to happen.
On the micro side, it’s about performance. Recruiter performance, hiring manager performance, business performance. On the recruiter side, did every recruiter’s actuals meet expectations. I don’t say good or bad performance; I say did what we expected happen, and why. That variance helps set capacity for next year. Same with hiring manager performance. I expected a hiring manager to stick to their plan, show up for interviews, fill out scorecards, make decisions. If they didn’t, that impacts capacity. From the business side, are we positioned correctly with compensation. Do we have a good brand. Do we have the right press. Do we have tools to ingest applications and sort them to get the best candidates. Those three variances fuel my assumptions for what the business is asking next year. When I’m looking at assumptions for 2026, I’m looking at those three metrics from 2025.
Chris Mannion:
Exactly. What you’ve outlined is a packet that the HR leader or head of TA brings to the meeting so they can be fully conversant in everything on that list. They should be able to explain why they need to staff to 120 requisitions even though the plan is for 100. That information gives them ammunition for the discussion. Building on that, think about how we used to plan in the military. You have an expectation for a horizon. You can red team and come up with alternative scenarios, but you’re never going to accurately predict what will happen. Start to think through situations where you will have more information to make a better decision. You’re not locking in the 2026 plan on December 31 and executing without change. What happens at the end of January. Can we adjust assumptions. If you’ve gathered the data in that packet and built the model so it’s easily adjustable, you can adjust on the fly. With new information at the end of January, adjust your model and incrementally change the plan over the year. When planning recruiting capacity, you can know you will need a certain number of hires. Staff to that level knowing how long it takes to build a recruiting team. Be at capacity by April 1. If things change and you need more recruiters for the second half, you increase. If attrition spikes or is lower than expected, make tweaks. You’re adjusting the plan on the fly, not locking it in. Good teams do this. The quarterly review process accounts for it, assuming HR and finance are working from the same data. Too often finance is planning based on one set of metrics, HR on another, recruiting is gathering what they get. It gets messy. Agile planning structure is key for solving variance and having a successful 2026, even when you don’t know exactly what will happen.Eric Guidice:
On the finance side, I did a podcast with Jim Miller, head of talent at Ashby. He had a resume writing tip: define X, the impact Y, the magnitude Z. That applies to getting 2025 data into 2026. We facilitate information to the team, but executives seldom want to get into details. We need to say this happened X, it had this impact Y, at this magnitude Z. When we look at plan change rate or recruiting capacity vs. demand, we can say we did or did not have enough capacity. That’s the first part. But you're not differentiating yourself if you only bring what happened. To differentiate yourself as a recruiting leader with data, you take this information and say this is what happened, this is the impact, and this is the magnitude. For example, we didn’t have enough recruiting capacity. Therefore, we didn’t hire sales to plan. Therefore, we missed revenue by a specific amount. That story allows executives to focus on how to mitigate impact to get a better result. If you missed a million dollars in revenue and a new recruiter who could fill that job costs one hundred thousand dollars, you’ve essentially saved nine hundred thousand in lost revenue by investing in the recruiting team. Using the X-Y-Z methodology, you can take all of this and say this is what happened, why it matters, and the cost. That unlocks credibility so you can advocate for the best recruiting team. If you don’t get the team, you can advocate for more participation, better hiring manager scores, more efficient processes, or investing in a tool. Do you still want to lose a million dollars in lost revenue, or can I suggest solutions.Chris Mannion:
It’s important that the TA leader understands the unit economics of the impact of what they’re doing. Revenue to recruiting capacity is one of the cleanest links. You can tie it to missed revenue targets and whether that’s because there weren’t enough sales reps because recruiting underperformed, and whether recruiting underperformed because you didn’t have enough recruiters to deliver capacity. Had we hired two more recruiters at a cost of two hundred thousand, we would have closed that million-dollar gap because we would have hired them in the quarter if we had known the plan would change. Those conversations aren’t about throwing dirt on recruiting; they’re about collaborating better, learning from the past, and bringing clear, crisp discussion with data to back it up.Eric Guidice:
Another point that doesn’t get talked about enough is that in these meetings recruiting leaders catch strays. You’re planning for 2026 and suddenly you have to defend 2025 performance because a sales leader brought it up. It’s natural to assume the bottom of the funnel increases when you add to the top of the funnel. More engineers, more code. More sellers, more revenue. More recruiters, more hires. But you can also increase efficiency. An engineer doesn’t have a hiring manager slowing them down, but if you give them a slow computer they won’t produce as much code as someone with the latest tech. As a recruiting leader, when we come to the table with variance and impact, bring it back to the why. I delineate between did the funnel perform, did the recruiter perform, did the hiring manager perform. I include in hiring manager both the individual and the business or the reforecasting process. When you don’t meet expectations, have defensibility with data. When a hiring manager isn’t performing, I don’t say this manager was a problem. I say here are the departments. Here’s the percentage of scorecards they filled out, the percentage of interviews they rescheduled, how many times they changed the plan while we worked on it, how many times they went over band or over level. I’m not saying this manager is bad. I’m showing data and correlated performance. If you solve one, the other often solves. What do you want to do. It’s a collaborative effort. I want executives to recognize they have an equal input into hiring success as the recruiter does, just like a computer’s processing power impacts an engineer’s output as much as the number of engineers. Looking at what data can help from 2025 into 2026, you have data to help forecast the plan, to staff your team, and to defend performance. Hopefully you’re not navigating all of that in one conversation, but you need that preparation because we’re under that level of fire. We have too much impact on the business and financials for people not to pay attention, especially in Q4.Chris Mannion:
Those metrics are important. Two reminders. One, I used to build the Recruit Performance Deck for our internal QBRs. An approach that works is to show perfect delivery. If we, as a recruitment organization, delivered against capacity, this is how many hires we would have made. Then break down the things that went wrong. Slow feedback from hiring managers so we lost candidates. Uncoordinated interview scheduling or lack of availability. Poor top of funnel. Priorities changed. Bucket those up. TA leaders intuitively know the causes, but if you tag lost candidates or hires based on those criteria, you can build a simple dashboard that says we would have hired 100 people this quarter, we hired 85, and here’s where the 15 we missed were accounted for. Top five and other categories. Use it as a monthly or quarterly snapshot of recruiting performance. Once you have that, show the things you did to improve. For example, 24-hour SLAs for interview scorecard feedback. From Q1 to Q2, this changed and this was the impact. Instead of hiring 80 people, we hired 85. Net increase of five over the quarter is a big lift. At year end, you have not just performance and reasons for missing targets, but also, had we not done the things we did, this is what would have happened. You can show measurable impact. To close the gap, here is what we want to do next. This is how we’re going to fix variance, which is one of the top reasons you didn’t deliver against 2025 hiring goals. It’s a proactive way to approach the discussion. Instead of being defensive, be on the front foot, understand your data inside and out, understand where you can drive impact and where you did in 2025, and what you need as buy-in to hit goals in 2026. Tie it together. Over multiple years you have a narrative of increasing performance and simple business cases. If you need to onboard technology, change process, or add people, you already have unit economics and data points built in. The case is laid out and everyone understands the why and what. You don’t have to repeat yourself over and over.Eric Guidice:
That is sage advice for recruiting leaders getting promoted or looking to get promoted. Create that narrative. Data goes both ways. Being able to articulate and gain credibility using information from different sources is directly correlated to promotions. It would be interesting to lay out the data unique for the headcount planning process from the headcount system rather than from an HRIS or ATS. The way I view it, the ATS is the funnel. There are hiring activities, conversion rates, time, scorecard completion rate, interview reschedules depending on tracking. There’s a lot of offer information relative to what was in the ATS. I’m curious what you pull out of the ATS. Those are the data points I pull to explain recruiting activity and hiring manager activity as context of production. What do you pull from the ATS. Did I miss anything. What are recruiting leaders pulling out of the ATS for 2026.Chris Mannion:
It varies depending on roles and business goals. Frontline warehousing roles are measured differently from exec roles. Understanding metrics as they apply is important. I had a leader who told me that because her team handled many role types, metrics were going into a washing machine and she couldn’t do anything with what came out. You need to segment metrics to show time, cost, and quality of hire by vertical and level. Don’t intermingle data that hides actionability. You might see time to hire go down and cost per hire go down, but if you shifted focus from senior to junior hiring and hired many entry-level sales roles, which fill quickly, you’ll see different metrics than if the strategy was different. That’s where understanding scenarios and the did-this-then-that framing matters.When you go into the ATS, don’t just pull all data as listed. I haven’t seen ATS analytics I could use accurately without exporting. Pull it out and parse fields. Create definitions yourself. Track time-in-stage to understand movement through the funnel. Track top-of-funnel to bottom-of-funnel metrics. How many recruiter screens to get a hire at the bottom. That helps you plan for next year. You can see if you have talent density in the areas you’re focused on to hit goals, assuming growth. Look at conversion rates between stages to build a predictive view of unit economics for each hire. Then build the recruiting capacity model knowing it takes longer to hire an engineer than a campus hire. Segment. Use historic time to fill. Break down exit rates at each stage and pass-through rates. Track over time what you do to change them. That builds the narrative and shows plans for 2026. Don’t make big assumptions about changes you’ll make, but you can say we integrated a new assessment tool that will better filter candidates from top of funnel to hiring manager screen, so we expect hiring manager-to-offer percentage to increase. That reduces raw recruiting capacity requirements and increases productivity and value by a given amount. You’re starting to build the narrative around unit economics the business uses.
Jumping ahead to HRIS and other tools, start thinking about outflow. I like to think of inflow and outflow with organizational activities in the middle. Balance supply and demand. Demand comes from exits and growth of the middle. Ensure inflow of supply keeps up. In HRIS, look at time in role to understand average time in role, attrition rate by time in role, by level, function, and geography. Come up with assumptions of where you’ll see gaps. Identify high performers in role for a long time who haven’t been identified for an internal move or promotion. Start those conversations early and bake them into planning assumptions. If a suggestion comes up that you need a new team and a leader to build it out, you already have a short list of people likely to look for new roles after bonus season. You can set them up for success in 2026. That reduces overall recruiting need because you don’t need to backfill or hire a brand new person for a complex role. You’re bringing metrics together. The important thing is how to tell the story, bake the narrative in, and show how things will be different in the coming year.
Eric Guidice:
Through your funnel conversion example you tied everything together and brought up the importance of tracking year-over-year data. If you measure funnel conversion rate and think a tool will help top of funnel efficiency, you create an assumption on how many recruiters you need or how many applications you can process. You will need to answer for that the following year. You’ll make an assumption based on recruiting capacity plus tool vs. recruiting capacity alone on the funnel capacity rate, and next year you’ll need to say whether it was true. You can have assumption accuracy or a success metric there. In doing so, you’re creating ROI. When you go to buy that tool, you’re tangibly saying to finance, see the difference in recruiter capacity, that’s the ROI on the tool, therefore we can purchase. The following year, you decide whether the tool is justified based on the ROI of top of funnel efficiency you gained. Understand what you did this past year. Figure out ways to improve or change efficiency based on your assumptions. Measure them and figure out the ROI and impact, then year over year report on that success so you can continually improve assumptions in workforce planning. I like that.The last thing I want to cover is what’s unique from headcount data. Many customers were previously on spreadsheets or using workarounds that enhance spreadsheets or tools like Asana, Monday, Notion. What does headcount data, the data from the headcount plan, give you that you can’t produce from the ATS or HRIS. What are you showing people from the headcount data that’s brand new or very hard to pull from existing systems.
Chris Mannion:
One thing CHROs and CFOs realize when headcount goes over budget is that something is wrong in the system or data. It’s not one person doing their job incorrectly. It’s the marrying of systems. You have finance, HRIS, ATS, and often a separate requisition tracking system. In each system there are different ways to link data and often they don’t talk to each other. There’s an employee ID in finance that doesn’t match the employee ID in HRIS, which doesn’t match the candidate ID in ATS, which doesn’t match the rec ID in the custom tracker. When you try to tie everything together, you see differentials between compensation assumptions, comp offered, comp authorized, and comp of the person you’re backfilling. Finance will focus there. Even just thinking of leveling and how a role is specced and how we track time to hire. Is it from when you open the rec to when the candidate was closed. Is it when they are in the seat. Is it when they are fully ramped. Finance cares when cost hits the P&L. Recruiting measures from when the rec is closed in the ATS. The requisition might not be closed in the tracker until the person is actually in the seat and hasn’t reneged the day before joining, which happens. The main differences are assumptions between cost and date, which drastically affect cost per hire and time to hire. If you want to look at quality over time, reduce 90-day attrition, or increase first-year performance, you need to draw a line from the latest performance review back to the top of the funnel and back to when the requisition was scoped. Did we scope this correctly. Did we get the right people in the top of the funnel. Did we move people through in a way that bubbled the top people to the surface and interviewed them fairly with a solid assessment, then get that person into role. It’s not just whether the person joined and was a good fit, or whether that is the hiring manager’s fault. How do you group it all together to give a holistic picture. No system inside an organization right now, HRIS or ATS, is going to do that. You need to link all the data to get the holistic picture.Eric Guidice:
When we’re selling Headcount365, we talk about context. Every individual thing makes sense in isolation. If I want to make an offer and need somebody now, I’m going to go over band. But how many times did I go over band, who is doing it, and what’s the impact on the budget. What does that do to funnel conversion rates. The idea that I can track every requisition’s intended initial state and any change from it before it goes into the ATS, when it’s in the ATS, and when that person is employed is adding context to workforce planning. You’re getting an additional data set that says what the requisition intended and what actually happened. In that are specifics like level changes, start date changes, and salary changes. How many of those requisitions were assigned to a recruiter versus what they produced. The changes that happen to requisitions and the implication of those changes. A change before recruiting starts is less impactful to recruiting than one while they’re working on it. A compensation change or a level change is more predictable for HR before the offer than a last-minute change to save a candidate. The ATS will show individual requisition stories. The headcount plan tells you the group of requisition stories in context of how they got there. It’s an added data set that improves the planning process. Objectively, my assumptions vary less year over year. My plan change rate reduces year over year. The recruiting sentiment or hiring manager perception improves because we now have data to communicate what was supposed to happen, what actually did, and why. If you’re relying on a spreadsheet, you have a lot of manual work. I started my career building this in a spreadsheet. It’s hard to update and track requisition history over time. There are metrics that are difficult to track, like what happened to a requisition over time or what’s going on with an individual position.If I had to summarize, when coming from 2025 into 2026, you need to know what happened and how it changed from your original plan. You need to know why and the impact. That needs to happen at the aggregate so you can talk to the executive team, and you also need to helicopter down to a department, cost center, or requisition so that as you defend or promote your position, you have a data set to support it.
Chris Mannion:
Right on, nothing more to add. That hits everything.Eric Guidice:
Variance is the storyteller. Happiness or unhappiness comes from something you thought would happen and then something different happened. There are many stories to tell. If you don’t track variance and then track it year over year to see trends, you’ll start every workforce plan from scratch. Without year-over-year headcount data to inform trajectories of assumptions or the relationship between recruiting capacity and demand over time, you’ll start every plan year from zero. If you don’t set up a project with rules and references, you start every new effort from scratch. Add your rules, add your references, get smarter, and your workforce plans will be more accurate. Your finance team will be more on budget. You’ll unlock more dollars for recruiting. You’ll create a process that is accepted by the business, both objectively in performance and subjectively with feedback.Chris Mannion:
A lot of organizations historically relied on one person who has corporate knowledge from the last decade of planning cycles. With high turnover and new companies, that’s not possible. You need data to drive decisions. Getting out of spreadsheets is job number one, because compiling 12 months of spreadsheet data and inferring a pattern takes a long time. Who has time to do that if you’re already executing at a high level.Eric Guidice:
Shout out to the forward thinkers who reach out to us because they have one person who does it all and realize that single failure point is risky. Another fantastic episode. We’ll be back next week with more. I’ll put a link in the description for folks to participate if you want to join us on the podcast. I’d love to have other guests on. Until episode four, have a great week.
The Headcount Planning and Variance Relationship
Headcount variance measures the difference between what headcount activity was planned and what actually happens in hiring, HR & Finance. The core value of headcount365 is capturing headcount plan variance from the actions of hiring managers & recruiters after the plan is released
There are many types of headcount variance within each category that help solve problems across the company, but for the purposes of annual headcount planning, we’re going to focus on the following:
Total Plan Variance: Difference between planned and actual filled roles.
Time Variance: The delay between planned start dates and actual hire dates.
Cost Variance: Salary or total labor cost deviations from the plan.
Activity Variance: Unexpected exits impacting net headcount.
Variance functions as a real-time feedback loop between Finance, Recruiting, and HR. It transforms static headcount models into living systems that learn from every plan change, delayed hire, or unexpected departure.
Root Causes of Headcount Variance
Variance is rarely random and can be the byproduct of misalignment and/or the ever-changing conditions businesses operate within.
Lagging headcount data from spreadsheet-based data connections of hiring manager or recruiter behavior to the FP&A tool, HRIS, or ATS integrations.
Optimistic assumptions about time-to-fill or hiring velocity, interviewer availability, compensation, offer to accept rate, or other key metrics
Approval delays that push roles past the intended quarter.
Attrition spikes that invalidate earlier assumptions.
Each of these factors compounds over time, creating blind spots that erode trust in both the plan and the data.
How Variance Impacts Each Function
Finance: Variance erodes forecast reliability, affects labor cost accuracy, and introduces volatility into EBITDA predictions.
Recruiting: It distorts capacity plans, workload balance, and prioritization across functions.
HR & Workforce Planning: It challenges data trust, model accuracy, and can surface early cultural signals like turnover spikes.
Executives: It affects investor guidance, productivity metrics, and the credibility of the company’s talent strategy.
When variance is unmanaged, every stakeholder experiences a different version of the truth.
Variance During the Headcount Planning Process
High-performing organizations use variance to shift from reactive reporting to proactive forecasting. With headcount365, teams get real-time variance tracking.
Approval systems create real-time variance tracking, giving teams control over changes to the plan as they happen, vs waiting for a reconciliation.
Rolling variance reviews each month or quarter reveal emerging risks before they affect budgets.
Trendline analysis shows whether planning accuracy is improving or deteriorating.
Variance accountability frameworks help hold hiring managers, recruiters, and finance partners to shared performance standards.
Variance turns planning into a continuous improvement cycle rather than a once-a-year compliance task.
Headcount365’s Variance Intelligence Framework
Headcount365 approaches variance Intelligence through three critical data series:
Requisition-level variance – how plan vs. actual hiring performance evolves by role or department.
Recruiting capacity vs. demand – whether recruiting output matches hiring demand.
Plan change rate – the pace at which plans evolve due to shifting business needs.
This framework surfaces the why behind variance — approval bottlenecks, offer rejections, delayed backfills, or unexpected attrition — and isolates them by department, role type, or geography. The result is a unified dataset that Finance and People teams can trust, visualized through executive-ready dashboards.
Quantified Value of Managing Variance
Companies that systematically track and act on headcount variance see measurable gains:
40% reduction in plan reforecast time.
25% faster approval cycle times.
15% fewer hiring delays.
2–3x improvement in Finance’s confidence in workforce projections.

Conclusion
Variance is not failure; it’s information.
The best organizations don’t hide from variance; they harness it. Continuous variance analysis transforms headcount planning from a backward-looking budgeting exercise into an adaptive workforce strategy.
When every team treats variance as a shared signal instead of a problem, headcount planning evolves from static to strategic.
