Growth Model Assumptions

Understanding the assumptions behind your growth model is critical for accurate planning and forecasting.

Reverse Engineering the Funnel​

Start with revenue targets and work backward to calculate required metrics. Understanding your sales cycle and conversion rates is key. Once you know how many leads it takes to seal a deal, you can reverse engineer the process to pinpoint the number of SQLs, MQLs, and brand awareness required to meet your revenue target.

Aligning Executive Leadership and Functional Teams​

Use the "W method" - asking questions beginning with "W" (What, Why, Who, When, Where) to ensure organizational alignment on growth objectives:

  • What are our revenue targets?
  • Why are these targets important?
  • Who is responsible for each component?
  • When do we need to achieve milestones?
  • Where will growth come from?

Capturing Assumptions​

Despite available data, assumptions remain necessary when modeling growth factors:

  • Product launches - timing and market reception
  • Sales team scaling timelines - recruitment and ramp periods
  • Market conditions - competitive landscape and economic factors
  • Conversion rate changes - improvements from process optimization

Document all assumptions clearly so they can be validated and adjusted over time.

Continuously Monitoring and Adjusting​

Growth modeling requires ongoing attention:

  • Remain agile to market changes and competition
  • Track progress against the plan regularly
  • Update assumptions as new data becomes available
  • Communicate changes to all stakeholders
