AlthĂ©a is launching its new podcast titled “Simply”, a series that aims to demystify complex topics related to organization, business transformation, and operational performance. The concept? Experts engage in educational discussions, free of unnecessary jargon, to offer professionals accessible insights into sometimes technical business issues.

For this very first episode, we brought together Xavier Kelma, Expert GTA Manager at AlthĂ©a, and Geoffroy d’Argenlieu, president and co-founder of Timeskipper, a key AlthĂ©a partner and platform specializing in activity management. Together, they decipher two central concepts: Workforce Management and Activity Management.

Understanding the fundamentals: Workforce Management vs. Activity Management

  • Workforce Management aims to plan human resources according to operational needs.
  • Activity management, on the other hand, consists of adapting the workload based on objectives, field conditions, and daily contingencies.

“One manages the who, the other manages the what,” summarizes Geoffroy d’Argenlieu.

The complementarity of the two approaches becomes evident. One without the other risks unbalancing teams, losing efficiency, or exposing employees to degraded working conditions.

Finding the balance between HR, finance, and operations

A strong theme of the episode is the HR – Finance – Operations triptych and the need to create an integrated vision between these three dimensions.

“When one of the three takes precedence, the imbalance becomes visible: overload, disengagement, inefficiency,” warns Xavier Kelma.

Workforce management here becomes a strategic tool serving a holistic vision of the company: it structures the organization, provides visibility, and enables both management and managers to make balanced decisions.

Tools serving people and performance

Beyond algorithms and data, these tools are primarily managerial levers.

“The major challenge is certainly not to make people rush,” Geoffroy reminds us.
“It’s about performing tasks under normal, calm conditions, while preserving teams in the long term.”

It is even recommended to plan for some flexibility, with approximately 5 to 8% of unplanned time, to absorb contingencies — absences, activity peaks, technical incidents


The goal is not overperformance, but balanced occupancy, sustainability of effort, and quality of service rendered.

“It’s not about going faster, but about better utilizing people during their working hours.”

When to start a Workforce Management project coupled with activity management?

Among the signals that should alert a company:

  • an unstable organization,
  • recurrent absenteeism,
  • a high turnover rate (up to 30% in some sectors like retail),
  • imbalances between HR, finance, or operational departments,
  • or quite simply, the need to improve the working environment.

“A good project can emerge when the company starts asking itself: how can we do better?”

The current context – post-Covid, labor shortages, digital transformation – pushes us to revisit the fundamentals of work organization. Workforce management becomes a driver of economic and social performance, helping to better reconcile employee expectations and business imperatives.

Managing differently: tools for fairer management

Our two experts finally emphasize the managerial role: planning, daily steering, adjusting according to events, explaining priorities


“These are managerial times that need to be managed,” summarizes Geoffroy d’Argenlieu.
“And these tools support this steering posture in service of the collective.”

Workforce management thus becomes a tool for equity and anticipation, allowing managers to avoid becoming hostages of their teams or spending their time limiting damage.
