Workforce Planning: Plan Your Headcount 1 to 2 Years Ahead

How to turn a business plan into a people plan, find skill gaps, and decide whether to hire, develop, or borrow talent, with steps to start this month.

At the start of the fiscal year, every department sends HR a headcount request at once. Sales wants 5 more people, IT wants 3, and Finance says a senior accountant will retire mid-year. Every request sounds reasonable, but the budget is limited and nobody can say clearly what kind of people the company will need 18 months from now. If you are in HR or own a business and face this every year, workforce planning is the tool that stops people decisions from starting at zero each time.

What is workforce planning?

Workforce planning is the process of comparing the people and skills your organisation has today (supply) with what it will need in the next 1 to 2 years based on the business plan (demand), then closing that gap by hiring, developing current staff, moving people, or using outside talent. It differs from a headcount budget because it starts from business goals, not from last year's numbers plus a bit more.

Step 1: Translate the business plan into work

Do not start by asking how many people you need. Start by asking what the company will do differently next year.

• Will you open new branches, expand to other provinces, or sell more online?
• Is a new system coming in, such as an ERP or AI tools, that will change how some teams work?
• Are any products or services being scaled down or dropped?

Example: a retailer aiming to grow online sales may not need any more store staff at all, but it does need people to run marketplaces, create content, and analyse customer data. If you only look at each department's current headcount, you will never see this.

Step 2: Map the people you have now

Build a simple table per team. You do not need expensive software; a spreadsheet is enough to start.

What to capture

• Each person's role, level, and core skills
• People likely to leave during the planning period, such as those near retirement or planning to relocate
• Roles that only one person can do (single points of failure)
• Each team's historical attrition, from your own company data

A common mistake is counting heads but not skills. A team of 10 may not have a single person who can analyse data.

Step 3: Find the gaps and choose how to close them

Once you compare demand with supply, each gap has several options, not just hiring.

• Build: develop existing staff, best when you have several months and people with a close foundation
• Buy: hire new people, best for skills you need right away that nobody on the team has
• Borrow: use freelancers, consultants, or part-time specialists for project-based work
• Redeploy: move people from shrinking work to growing work

Write down the reason for each decision in the plan. When leadership asks why a team is not hiring, you can answer immediately without digging up the data again.

Step 4: Build at least two scenarios

A usable plan has to handle uncertainty. Draft 2 to 3 scenarios, such as sales on target, below target, and faster than expected, and state which roles each scenario opens or pauses and who makes the call. That way you do not have to rebuild the whole plan when conditions change.

A good workforce plan does not predict the future correctly. It tells you how to move when the future does not go as expected.

What to avoid

• Writing the plan once and filing it away. Review it at least every quarter.
• Letting HR plan alone. Department managers know the work best and must be involved from the start.
• Planning only new roles and forgetting backups for critical positions. This links directly to succession planning.

How to start this month

1. Book one hour with leadership and ask what changes in next year's business plan.
2. Ask each team lead to fill in the table of people and current skills.
3. Pick one pilot team with the most change and run a gap analysis there first.
4. Decide for each gap whether to build, buy, borrow, or redeploy.
5. Put a quarterly review into the leadership team's calendar.

If your plan includes both skills to develop and roles to hire, read how to reskill existing employees for the build side, and post open roles through Plants.work for employers for the buy side.
