Capacity Planning 2.0: Using Historical Velocity to Predict Hiring Needs

How many Sales reps do you need to hit your 2027 goal? If your answer is "Let's hire 10 more and see," you are gambling with the company's runway.

The "Bottom-Up" Capacity Model

1. Rep Productivity (The Baseline)

What is the average quota attainment of your top, middle, and bottom 20%? You must use the Median, not the Average, to avoid being skewed by "superstar" outliers.

2. The Ramp Factor

A new hire doesn't hit quota on Day 1. You need a Ramp Model:

• Month 1: 0%
• Month 2: 25%
• Month 3: 50%
• Month 4: 100% Your capacity model must account for this "lost" revenue during the ramp period.

3. Lead Flow requirements

This is where RevOps connects Sales to Marketing. If you hire 5 more reps, do you have the marketing budget to generate the 500 extra MQLs they need to hit their numbers? If not, your new hires will sit idle, and your CAC (Customer Acquisition Cost) will skyrocket.

The "What-If" Analysis

Use your CRM data to run scenarios:

• "What if our win rate drops by 2%?"
• "What if our average deal size increases by 10%?" By building these variables into your capacity model, you can give the Board a range of outcomes rather than a single, fragile number.
