Capacity Planning

Capacity planning is how agencies match supply (their team's available hours) with demand (client work that needs to get done). It's the operational discipline of knowing, at any given time, how much work your team can take on, where the bottlenecks are, and when you need to add resources.

At its simplest, capacity planning starts with your total available hours. If you have 10 billable employees working 40 hours/week with a target utilization of 75%, your weekly billable capacity is 300 hours. If your current client commitments require 280 hours/week, you have 20 hours of slack. Enough to absorb a small project but not a major new client.

In practice, capacity planning gets more complex because different types of work require different skill sets. You might have excess capacity in your design team but a bottleneck in development. You might have overall spare capacity but your senior strategists are all maxed out, which means you can't start new projects that require strategic oversight. Good capacity planning breaks availability down by skill type, seniority level, and time horizon (this week, next month, next quarter) so you can make informed decisions about what to sell and when to staff up.

Without capacity planning, agencies oscillate between two painful states: feast (everyone's overworked, deadlines are missed, quality drops) and famine (people are on the bench, utilization craters, and you're paying salaries for people with nothing to do). Neither is sustainable.

Effective capacity planning lets you see problems before they hit. If you can see three months out that you'll need 400 developer hours but only have 250 available, you have time to recruit, bring on contractors, or adjust project timelines. That's proactive management. Without it, you're scrambling to hire when you're already drowning — and desperate hiring leads to bad hires.
