Capacity Planning

Why It Matters

Most teams chronically overcommit. They plan as if every person has 40 hours of productive project time per week, ignoring meetings, interruptions, administrative tasks, and context switching. Asana's Anatomy of Work research found that 60% of knowledge workers' time goes to "work about work" (communication, searching for information, status updates) rather than skilled, strategic work. This means teams have far less capacity than they assume, and planning without accounting for this gap produces commitments that were unrealistic from the start.

How It Works

Effective capacity planning starts with honest measurement of available time. For most knowledge work teams, a realistic capacity factor is 60-70% of total hours (after subtracting meetings, email, administrative work, and context-switching costs). From there, the team estimates effort for each work item and selects a set of commitments that fits within available capacity, with a buffer for unexpected work.

Inputs to Capacity Planning

• Available people: who is on the team this period, accounting for PTO, shared resources, and part-time allocations
• Available hours: total hours minus recurring meetings, administrative obligations, and support rotations
• Capacity factor: the percentage of "available" hours that translate to focused project work (typically 60-70%)
• Buffer: reserved capacity for unplanned work, production issues, and urgent requests (typically 10-20%)
• Skill constraints: certain work requires specific expertise, limiting who can do it regardless of total headcount

The Overcommitment Trap

When teams plan without realistic capacity data, they fall into a predictable cycle: overcommit, under-deliver, work overtime to close the gap, burn out, and repeat. Each cycle erodes trust (stakeholders stop believing timelines), quality (corners get cut under pressure), and morale (the team feels perpetually behind). Breaking this cycle requires the discipline to plan based on demonstrated capacity rather than aspirational targets.

Connection to Other Practices

Capacity planning is the foundation that makes sprint planning honest and WIP limits enforceable. Without it, teams set commitments based on what stakeholders want rather than what the team can deliver. It also connects directly to sustainable pace: a team that plans within its actual capacity can maintain consistent output without burning out.
