Capacity planning
Capacity planning is the process of understanding how much work your team can take on and ensuring that incoming projects are staffed appropriately. For agencies and consultancies, it sits at the intersection of resource management, project scheduling, and financial planning. Done well, it prevents over-commitment, reduces bench time, and keeps the team working at a sustainable and profitable pace.
What capacity planning involves
At its core, capacity planning requires two pieces of information: how much time each team member has available (their capacity), and how much time each upcoming project will require (the demand). The planner's job is to match supply to demand, factoring in skills, seniority, and any existing commitments.
Most agencies plan capacity on a rolling 4-8 week horizon for day-to-day scheduling, and a longer 3-6 month horizon for hiring, pipeline management, and financial forecasting.
Hard and soft allocations
Agencies often use two types of allocations when planning capacity. Hard allocations are confirmed project assignments: a person is definitively committed to a project for a given number of hours. Soft allocations are provisional: you are planning that a person might be needed on a project, but it is not yet confirmed.
Tracking both types gives resource managers a more realistic picture of available capacity. A person can be 100% hard-allocated on current work but have soft-allocated availability opening up in two weeks, which is visible to business development.
The consequences of poor capacity planning
When teams are over-capacity, projects are delayed, quality drops, and people burn out. When teams are under-capacity, revenue opportunities are missed and bench time reduces profitability. Both failure modes are expensive.
Agencies that rely on spreadsheets for capacity planning often discover mismatches too late, after a project is already in trouble or a key person is overbooked. Real-time visibility into allocations is the main reason agencies invest in resource planning tools.
Example
An agency wins a new project starting in three weeks that requires 80 hours of design time and 60 hours of development per month. The resource manager checks current allocations and sees the senior designer is fully booked but a mid-level designer has 40 hours free. They soft-allocate the mid-level designer and flag a hiring need, then plan to bring in a contractor to cover the gap.
