Navigating the different horizons of workforce planning

Introduction

Many French companies acknowledge that they lack clarity regarding their future skills requirements.

The result?

Emergency recruitment that can cost you 40% more, projects delayed due to a lack of suitable resources, and key talent leaving for the competition because their departures were not anticipated.

And this may well be your situation today.

You manage your human resources on a day-to-day basis, putting out fires rather than anticipating needs, and you wonder whether your HR function is truly aligned with your company’s future.

Stop.

It’s time for a radical change of approach.

Workforce planning isn’t just an accounting exercise to please your Finance department.

It is a genuine strategic lever that can help you turn HR constraints into competitive advantages.

And I’m going to explain why it’s important to fully understand the four time horizons of workforce management and how this can revolutionise the way you think about human resources.

Because here is the truth that few dare to say: an HR department that does not plan is an HR department that is at the mercy of events.

And in a world where the war for talent is raging, simply reacting is setting your organisation up for failure.

So, are you ready to move from a reactive HR department to a truly strategic one? To transform your function from a cost centre into a real driver of growth?

Why your current approach no longer works

Let me guess: you manage your workforce as you would manage a stock of goods.

A need arises, you recruit.

A departure looms, so you find a replacement.

A new assignment comes in, and you do your best to redeploy your available teams.

This approach is killing your company’s performance.

According to a recent KPMG study, companies that practise multi-horizon HR planning are 23% more productive and have a 35% higher retention rate for key talent than their competitors.

Why?

Because these companies have realised that managing talent isn’t about managing resources; it’s about orchestrating a symphony. And a symphony requires preparation, foresight and building note by note.

The 4 time horizons of workforce planning

This approach finally reconciles the urgency of day-to-day operations with the long-term strategic vision.

No more flying by the seat of your pants!

Because effective HR management isn’t limited to a single time horizon.

No, no.

To be truly strategic, it must incorporate four complementary dimensions which, together, form a coherent system of anticipation and action.

So make way for agile HR planning!

Horizon 1: workforce monitoring – the essential rear-view mirror

The key question: “Where are we REALLY at today?”

Question: Do you know exactly how many employees you have? I mean: really exactly. Including their skill levels, their risk of leaving, and their full cost.

Because that is exactly what headcount monitoring does. It gives you an ultra-precise snapshot of your current human capital.

This monitoring draws on historical data to provide a precise overview of your current human resources. It is your essential starting point.

In practical terms, this means:

• Regularly updated HR dashboards.
• Accurate reporting on payroll and vacancies
• Analysis of staff movements (new hires, departures, turnover)
• Monitoring of the demographic composition of teams
• Bonus: A detailed mapping of employees’ skills

Why it matters: Without this clear picture of the present, it is impossible to build a reliable forecast for the future. This is the foundation of any effective HR strategy.

Horizon 2: Operational planning – Focusing on the short term

The key question: “How can we optimise available resources?”

With a horizon of 1 to 12 months, operational planning focuses on making the best use of your current talent to meet the company’s immediate needs.

Your objective?

To make the most of your current talent.

This operational planning is your ability to turn constraints into opportunities. An absent employee? An opportunity to develop another’s skills. An unexpected peak in activity? The chance to test new ways of organising work.

In practice, this translates into:

• Management of schedules and assignments
• Adjusting staffing levels to cope with peaks in activity
• Redistribution of skills across projects and teams
• Contingency plans for planned absences

The secret nobody tells you: This operational agility takes preparation. The most successful companies have pre-established scenarios for 80% of the situations they may encounter.

This aspect ensures your organisation’s agility and its ability to maintain day-to-day performance, even when faced with the unexpected.

Horizon 3: tactical planning – anticipating medium-term needs

The key question: “Do I have the right resources to ensure performance tomorrow?”

Looking ahead 1 or 2 years is the aim of tactical planning. It forms the bridge between day-to-day management and the long-term strategic vision.

Here, you touch on the very heart of what sets the most agile organisations apart from the rest: their ability to anticipate.

Remember that recruitment mistakes can cost you up to €150,000! Proactively anticipating human resources needs significantly reduces these costs as well as recruitment times, thereby improving the company’s operational performance.

But be careful: anticipating does not mean guessing. It means building robust scenarios based on your business strategy and market developments.

Your tactical action plan includes:

• Recruitment scenarios tailored to annual objectives
• Anticipation of requirements linked to your new projects
• Adjustments to staffing levels based on seasonality
• Training plans to develop priority skills in the medium term

Why it matters: This approach allows you to anticipate talent needs before they become critical and ensures you can meet your operational objectives.

My advice:

(1) Stop recruiting when you need to. Start recruiting when you know you will need to.

(2) Identify and develop the potential for growth within your existing staff before looking externally.

Horizon 4: strategic planning – shaping the future of your organisation

The key question: “What will my organisation need the day after tomorrow?”

Over a 2-5 year horizon, we enter the realm of Strategic Workforce Planning. This is where your ability to transform your organisation comes into play, before the market forces you to do so.

Here we are talking about a long-term HR vision, perfectly aligned with the company’s overall strategy.

And believe me, in a world where artificial intelligence is reshaping professions, where talent expectations are evolving at breakneck speed, and where sustainability is becoming a business imperative, this long-term vision is no longer a luxury.

It is a matter of survival.

Your strategic toolkit includes:

• A forward-looking mapping of future skills (not just current ones)
• Identifying roles undergoing transformation or emerging
• The development of career paths for your key talent
• Building an employer brand that attracts the talent your competitors are fighting over

Why it matters: It is this forward-looking perspective that enables you to prepare your organisation for the profound changes in the market, technology and talent expectations.

The ‘yes, but’ syndrome: why you’re still resisting

At this stage, I can guess your objections:

“Yes, but we don’t have the tools…”

“Yes, but it’s complicated to implement…”

“Yes, but we don’t have the time…”

Stop.

These “yes, buts” are exactly what keeps your HR function in a support role instead of making it a strategic driver.

The truth?

Your successful competitors started out with the same constraints as you.

The difference?

They chose to build rather than just go with the flow.

The idea isn’t to build everything at once, but rather to make the most of what you already have (because yes, you already have plenty of resources to get started).

For example, you already have information on your workforce. What’s stopping you from starting a simple dashboard with some initial metrics?

You surely have job descriptions? Why not start with this as a basis to map out your employees’ current skills?

And you don’t need to invest in a state-of-the-art tool straight away! Excel will be your best ally to get started!

The art of bringing different perspectives together

True HR performance does not lie in excellence in just one of these areas, but in your ability to get them to work together.

Imagine a conductor who only made the violins play. You’d get sound, perhaps even a melody. But you’d never have a symphony.

This integrated approach allows you to:

1. Ensure consistency between your day-to-day actions and your five-year vision
2. Optimise your investments by avoiding panic recruitment that costs a fortune
3. Secure your critical talent before they become a scarce commodity on the market
4. Steer your organisation’s transformation in a gradual and controlled manner

Where do you stand with your HR goals? : Your 5-question HR check-up

Let’s be honest.

Where do you really stand?

• Do you have a clear, data-driven picture of your current workforce? (Not just the numbers, but their actual potential)
• Are your resource allocation processes agile and effective in the short term?
• Do you anticipate your recruitment needs at least 12 months in advance?
• Have you identified the five critical skills you’ll absolutely need in three years’ time?
• Do your various HR departments communicate with one another, or do they operate in silos?

If you answered ‘no’ to more than two questions, it’s time to take action.

What now? To take your approach further

Implementing a multi-horizon approach to workforce planning requires:

• Tools tailored to each time horizon
• HR governance that integrates these different dimensions
• Strong alignment with the company’s overall strategy
• A culture of foresight shared by managers
