Capacity planning
Capacity planning tool to anticipate your team's workload
Capacity planning is the process of anticipating your teams' workload relative to their available capacity, in order to avoid overloads and under-utilization. Orbit PM integrates capacity planning at the core of its allocation module, with automatic visualization of forecasted workload on a rolling horizon.
Definition
What is capacity planning?
Capacity planning is the management practice of evaluating the available work capacity within a team and comparing it to the forecasted needs of upcoming projects.
Concretely, a team's available capacity represents the total number of productive person-days over a given period — taking into account leave, absences, training, and non-billable time. Demand, on the other hand, corresponds to the volume of work required by all current and upcoming projects. Capacity planning puts these two data points side by side, week by week, to highlight tensions before they become crises.
In the context of professional services teams (agencies, IT services firms, consulting companies), capacity planning is essential for:
- Avoiding team member overload (burnout, delays)
- Avoiding under-utilization (lack of profitability)
- Anticipating recruitment needs or subcontracting
- Planning the acceptance of new missions
- Making trade-off decisions on project priorities
Capacity planning in Orbit PM: each team member has a defined daily capacity. Orbit PM compares in real time the sum of planned allocations to this capacity and displays the resulting overload or availability with an automatic color code.

IT services firm challenges
Why capacity planning is critical for IT services firms
In an IT services firm, human resources are both the main asset and the main cost. Poor capacity management directly translates into margin degradation, delivery delays, and increased staff turnover. Here is why the capacity planning discipline is non-negotiable for any IT services firm that wants to scale sustainably.
- →Billing depends directly on the utilization rateEvery non-billed consultant day is a day of cost with no return. Capacity planning allows you to detect activity gaps in advance and fill them with new missions before they occur.
- →The sales pipeline must align with real capacitySelling a mission that cannot be staffed on time is the classic mistake of growing IT services firms. With a forecasted capacity view, salespeople know exactly which profiles are available, at what date, and for how long.
- →Multi-assignment of consultants creates invisible tensionsA consultant working 60% on one project and 50% on another is overloaded — without anyone realizing it if assignments are in separate spreadsheets. Capacity planning consolidates all assignments and makes these tensions visible.
- →Mission endings create unpredictable workload gapsThe end of a contract or mission represents a threat to the utilization rate. Capacity planning on a rolling horizon (3 to 6 months) allows you to anticipate these mission endings and engage renewals or repositioning in time.
- →Recruitment must be anticipated several weeks aheadRecruiting a senior profile takes 6 to 10 weeks on average. Without visibility into future workload ramp-ups, IT services firms recruit too late, chain emergency subcontracting contracts, and degrade their profitability. Capacity planning anticipates these needs well before the tension.
Method
5-step method for capacity planning
Whatever the size of your team, this method structures the capacity planning approach to achieve reliable and actionable visibility.
Inventory your team's real capacity
Start by listing each team member with their nominal capacity (full-time, part-time, daily subcontractor). Then deduct planned leave, training days, known absences and structural non-billable time (internal meetings, pre-sales). You thus obtain the net available capacity per period — this is the true ceiling of your productivity.
List your project and mission pipeline
List all ongoing projects and signed or near-signed missions. For each one, estimate the person-day requirement per profile (senior developer, project manager, functional consultant…) and per week. Include the probable commercial pipeline — even with a realization coefficient (e.g. 70% of won bids materialize). This view of forecasted demand is the other half of the equation.
Calculate the forecasted workload by profile
Compare available capacity and project demand, profile by profile and week by week. The workload / capacity ratio is your forecasted utilization rate. A rate above 100% indicates potential overload; a rate below 50% signals an under-billing risk. In Orbit PM, this calculation is automated as soon as you enter allocations: the workload view updates in real time.
Identify and analyze gaps
Once workload is calculated, analyze the gaps between what you have and what you need. Distinguish critical gaps (sustained overload of a key profile, prolonged billing slack) from temporary ones (absorbable one-week peak). For each critical gap, identify the root cause: underestimated mission? Delayed recruitment? Commercial mission not yet confirmed?
Adjust and update continuously
Capacity planning is not an annual exercise: it is a living process. Depending on detected gaps, your adjustment levers are: reallocating an available team member, delaying a mission start, activating a subcontractor, or accelerating a recruitment. Establish a weekly or bi-weekly workload review ritual to maintain plan reliability and adapt decisions to portfolio evolution.
Business benefits
What capacity planning brings to your organization
Anticipating tensions
Identify overload periods 2 to 4 weeks in advance. Make decisions before the situation becomes critical.
Better profitability
Optimize the utilization rate of your profiles. Reduce non-billable downtime and improve your mission margins.
Easier trade-offs
When a new project arrives, immediately evaluate whether you have the capacity to absorb it or need to reinforce the team.
Burnout prevention
Undetected chronic overload leads to exhaustion. Orbit PM makes overload visible so you can act in time.
Recruitment planning
Identify recurring tension periods to calibrate your recruitment or subcontracting needs upfront.
Controlled growth
Accept new client projects knowing exactly what capacity you have available and when.

How Orbit PM automates your capacity planning
Orbit PM does not replace your capacity planning process — it tools and accelerates it. Where a spreadsheet would require hours of consolidation and fragile formulas, Orbit PM calculates workload in real time as soon as an allocation is created or modified.
Concretely, here is what Orbit PM handles for you:
- Automatic calculation of each team member's utilization rate
- Instant detection of overloads with color coding
- Consolidated view of workload across all your projects simultaneously
- Allocation history for comparative data
- Data export for steering committees and reporting
Result: your team spends less time preparing planning meetings and more time making good decisions. Also see our page on resource allocation to understand how to assign your team members at the operational level.
What managers using Orbit PM say:
"Before Orbit PM, I spent 2 hours every Monday consolidating availabilities in Excel. Today, I open the workload table and have the answer in 30 seconds."

FAQ
Frequently asked questions about capacity planning
What is the difference between capacity planning and resource planning?
Capacity planning focuses on the overall capacity available within a team and compares it to forecasted demand (projects, missions, sprints). Resource planning goes down to the individual level: who does what, when and at what rate. The two practices are complementary: capacity planning provides the strategic framework, resource planning operationalizes assignments. Orbit PM integrates both levels in a single tool.
How do you implement capacity planning in an IT services firm of 20 to 100 consultants?
The recommended 5-step method: (1) inventory the real capacity of each consultant, (2) list the project pipeline with their person-day requirements, (3) calculate the forecasted workload week by week, (4) identify gaps (overload or slack), (5) adjust by recruiting, subcontracting or shifting certain missions. Orbit PM automates steps 3 and 4.
Is Orbit PM suitable for capacity planning in a digital agency or consulting firm?
Yes. Orbit PM was designed for professional services teams: digital agencies, IT services firms, consulting companies. Each profile can simultaneously manage multiple projects with different engagement rates. The workload view automatically aggregates all allocations per team member and signals overloads or availability in real time.
