Hiring often starts with a complaint.
A sales manager says the team is overwhelmed. Customer support has a growing backlog. Finance can’t close the books as quickly as it used to. Someone suggests opening a new position, a job description gets drafted, and recruiting begins.
For a growing company, that sequence can become expensive.
Workforce planning starts earlier. Instead of asking, “Who should we hire?” leaders first ask what work the business expects to have, which capabilities that work requires, how much capacity already exists, and which gaps actually need another full-time employee.
That distinction matters when recruiting itself carries a meaningful price tag. According to SHRM’s 2025 recruiting benchmarking research, the average cost per hire was $5,475 for nonexecutive positions and $35,879 for executive positions. Average time-to-fill was roughly a month and a half for both groups.
Waiting until employees are already overloaded means a company may spend six weeks or more recruiting while the capacity problem continues.
A better workforce plan connects expected business demand with skills, staffing options, budgets, and clear hiring triggers before the shortage becomes urgent.
Start With Business Demand, Not Job Titles
Workforce planning works best as a forecasting exercise.
Suppose a software company expects revenue to grow 25% next year. That number alone doesn’t tell leaders how many people to hire. They need to understand what the growth will actually create.
Will 25% more revenue mean:
- 25% more customer support tickets?
- More sales demonstrations?
- Additional implementation projects?
- More invoices and collections?
- More compliance work?
- Higher demand for engineering?
- More management responsibilities?
Different businesses scale differently.
A professional services firm might see employee workload rise almost directly with revenue. A software company may be able to serve thousands of additional customers with relatively little additional staffing in some departments. A manufacturer might face production limits long before its administrative teams reach capacity.
Start by translating growth targets into units of work.
If customer volume is expected to rise from 2,000 to 3,000 accounts, estimate how many support cases, onboarding hours, account reviews, invoices, and renewals those additional accounts are likely to produce.
Those estimates don’t need to be perfect. They need to be useful enough to expose where pressure is likely to appear.
For businesses planning future workforce needs, connecting business forecasts with future roles and skills can help leaders make staffing decisions before demand becomes an emergency.
Build a Simple Skills and Capacity Inventory
Once leaders understand likely demand, the next question is: What can the current team already handle?
Headcount alone gives an incomplete answer.
Two companies may each have 20 employees but have very different levels of available capacity. One may have employees working comfortably below their limits, while the other may already have teams relying on overtime and delaying lower-priority work.
Create a basic inventory that looks at both skills and capacity.
For each team, record:
- Major responsibilities
- Important technical or operational skills
- Current staffing level
- Approximate available capacity
- Work that is frequently delayed
- Skills concentrated in only one employee
- Skills the company expects to need within the next 6 to 18 months
This exercise often reveals that the apparent staffing problem isn’t actually a lack of people.
A company might discover that five employees spend several hours every week manually building reports that could be automated. Another might find that a capable internal employee could take over a new responsibility after a short training program.
The goal is to understand where additional human capacity is truly needed before adding payroll.
Identify Gaps Between Current Capacity and Future Demand
With a demand forecast and workforce inventory in hand, leaders can compare where the company is heading with what the current team can support.
These gaps generally fall into two categories.
Capacity gaps
The company has people with the right skills, but not enough hours to handle projected work.
For example, a company may already have customer success specialists who can manage about 100 accounts each. If the business expects to add 350 accounts next year, managers can estimate when existing capacity will run out.
Capability gaps
The company lacks a skill it expects to need.
A business preparing to sell into larger enterprise accounts might need stronger security, compliance, procurement, or contract-management expertise even if its current staff still has available time.
This distinction changes the staffing response.
A capacity shortage may call for another employee doing work the business already understands. A capability shortage might instead require training, an experienced hire, a specialist contractor, or outside expertise.
Skills shortages remain common. In SHRM’s 2025 Talent Trends research, 69% of organizations reported difficulty recruiting for full-time roles. The same research found that 28% said new skills were required for full-time jobs, while 47% had updated existing roles to require additional skills.
Hiring plans built around last year’s job descriptions can therefore become outdated quickly.
Decide Whether to Build, Buy, Borrow, or Automate
Finding a workforce gap doesn’t automatically mean opening a requisition.
Leaders should evaluate several ways to obtain the capacity or capability they need.
Build: Develop someone internally
Training an existing employee can make sense when the skill is closely related to work the person already performs.
Internal development may also preserve business knowledge that would otherwise take a new hire months to learn.
Ask whether the skill can reasonably be taught before the business needs it. Training that takes six months won’t solve a problem expected next month, but it may be the best answer for a need expected next year.
Buy: Hire a full-time employee
Full-time hiring makes more sense when demand is ongoing, workload is predictable, and the role needs to stay closely connected to the organization.
Before approving the role, estimate its full annual cost rather than salary alone. Include payroll taxes, benefits, recruiting expenses, equipment, software, management time, and onboarding.
Recruiting difficulty should also be part of the forecast. In August 2026, 35% of small-business owners reported job openings they couldn’t fill, according to the National Federation of Independent Business. That was 11 percentage points above the historical average.
If a hard-to-find skill will be needed six months from now, recruiting shouldn’t necessarily begin six months from now. The hiring lead time needs to be included in the plan.
Borrow: Use contractors or outside specialists
Some gaps don’t justify a permanent hire.
A growing business might need 20 hours of financial modeling, six months of recruiting support, occasional cybersecurity advice, or temporary design capacity.
Contractors can be useful when workloads fluctuate or specialized expertise is needed for a limited period.
The tradeoff is that outside specialists may cost more per hour and may not develop the same organizational knowledge as employees.
Automate: Reduce the amount of labor required
Automation and AI add another question to workforce planning: Does this work need another employee, or could software handle part of it?
SHRM reported that AI use for HR-related tasks rose to 43% in 2025 from 26% in 2024.
That doesn’t mean companies should automatically replace planned positions with AI. Instead, managers can examine individual tasks.
Perhaps software can draft routine reports while employees review exceptions. An AI assistant might handle first-pass research while an analyst interprets the results. Automation could remove repetitive data entry without eliminating the need for the role itself.
The World Economic Forum’s 2026 Chief People Officers’ Outlook identifies redesigning organizational structures and roles, expanding reskilling, and deploying AI and automation responsibly as major priorities for people leaders.
That makes workforce planning partly a work-design exercise. Companies need to decide which tasks belong with people, which can be supported by technology, and what new skills employees will need as that mix changes.
Build Hiring Lead Time Into the Forecast
A common planning mistake is waiting until a team reaches 100% capacity before approving a position.
By then, it’s already late.
SHRM’s recruiting benchmark puts average time-to-fill at roughly a month and a half. That’s only the recruiting period. A new employee may then need weeks or months before reaching full productivity.
Think backward from the date when additional capacity will be needed.
If a department is expected to hit its practical capacity limit in September, and the company expects six weeks for recruiting plus six weeks for onboarding, the hiring process may need to begin around June.
Labor-market conditions can make that timing even less predictable. The U.S. Bureau of Labor Statistics reported an average of 7.1 million job openings during 2025, alongside 63 million hires and 38 million quits.
Businesses should therefore treat recruiting lead time as part of operational planning rather than something HR solves after a position receives approval.
Set Specific Triggers for Adding Headcount
Headcount discussions become easier when managers agree on hiring triggers in advance.
Instead of relying on statements such as “the team feels busy,” define measurable conditions that would justify opening a role.
For example:
- Customer support backlog exceeds a set threshold for four consecutive weeks.
- Revenue reaches a level that supports the position’s annual cost.
- Sales representatives consistently exceed their account capacity.
- Overtime remains above a chosen level for two months.
- A contractor workload reaches the point where a permanent hire would cost less.
- Project delays begin affecting customer commitments.
- A manager has more direct reports than the company considers manageable.
- Forecast demand will exceed available capacity before recruiting and onboarding can be completed.
The trigger doesn’t have to be a single number.
Companies can combine several signals, such as utilization, revenue, customer volume, backlog, and forecast workload.
The goal is to replace emergency hiring with a decision that leaders have already thought through.
Build a Hiring Budget Before Positions Are Approved
Workforce plans should connect directly with financial planning.
If the company expects to hire five employees next year, finance should know roughly when those hires are expected, what they may cost, and how sensitive the plan is to revenue performance.
Create several scenarios.
A base case might assume revenue meets the operating plan and all five positions are hired.
A slower-growth scenario could delay two hires by a quarter.
A higher-growth scenario could bring one role forward and add contractor support.
Small businesses are still adding staff, but growth patterns differ by company age. According to the U.S. Chamber of Commerce and MetLife Small Business Index, 23% of small businesses reported increasing staff during the prior year in Q4 2025. Among businesses operating for 10 years or less, 24% reported increasing staffing, compared with 11% of companies operating for more than 21 years.
For growing companies, a hiring budget can keep expansion connected to the economics supporting it.
Improve Recruiting Before Hiring Volume Rises
Workforce planning can also give recruiting teams more time to improve how they hire.
When a manager needs someone immediately, interviews often become rushed. Requirements get added without much thought. Teams may prioritize filling the seat over confirming whether the candidate can actually perform the work.
A longer planning horizon gives managers time to define outcomes, remove unnecessary requirements, and prepare structured interviews.
For example, reviewing the best interview questions for a role can help hiring managers focus conversations on skills, experience, judgment, and job-relevant examples rather than improvising during each interview.
That preparation matters when hiring costs thousands of dollars and a poor match can restart the entire recruiting process.
Review the Workforce Plan Every Quarter
A workforce plan shouldn’t be written once a year and forgotten.
Revenue forecasts change. Customers behave differently than expected. Automation projects finish early or late. Employees leave. A product launch gets moved. One department grows faster than another.
A quarterly review is frequent enough for many growing businesses.
During each review, ask:
- Has expected revenue or customer demand changed?
- Which teams are approaching capacity?
- Are planned hires still needed?
- Have any hiring dates moved?
- Which new skills are appearing in current roles?
- Can internal employees fill upcoming gaps?
- Are contractors becoming permanent parts of the workload?
- Has automation reduced or changed staffing requirements?
- Are recruiting lead times getting longer?
- Does the hiring budget still fit the company’s financial outlook?
Some planned positions may disappear. Others may become more urgent.
Changing the plan isn’t a failure. That’s the point of forecasting: update decisions as better information becomes available.
Conclusion
Growing businesses don’t need to predict every future job perfectly. They do need a clearer process than waiting for managers to become overwhelmed and then opening positions as quickly as possible.
Start with business demand. Translate revenue, customers, projects, and operational goals into expected workload. Compare that demand with the skills and capacity already available inside the company.
When a gap appears, decide whether the best response is to develop an employee, make a full-time hire, use outside talent, automate part of the work, or combine several approaches.
Then add the financial side: recruiting costs, compensation, hiring lead times, onboarding, and clear triggers for when additional headcount becomes justified.
With hiring costs reaching $5,475 for the average nonexecutive position and $35,879 for executives, staffing decisions are too expensive to treat as last-minute reactions.
A quarterly workforce plan gives founders, operations leaders, HR teams, and finance a shared view of where the company is heading and what kind of workforce it may need to get there. Hiring can then happen because the business forecast supports it — not simply because everyone is already stretched too thin.
