LESSON 3 OF 6 · ADVANCED
Backsolve an activity plan
Start with a clearly labeled goal and conversion assumptions. Divide the desired outcome by each conversion rate in reverse order and round required counts upward. Check that capacity can support the work. Planning assumptions are not promised results; replace them with relevant observations as evidence accumulates.
Use the pipeline builder to compare a base and lower-conversion scenario.
About 2 minutes reading + 12 minutes practice. Take longer when needed.
Apply the method
Backsolve from an outcome using explicitly labeled assumptions. Divide required starts by the offer-to-start rate, round up, then repeat through each earlier stage. Use stage names that match the organization’s definitions. Test a lower-conversion case and compare the implied workload with interview, recruiting and onboarding capacity. Include timing: activity started near the end of a period may produce outcomes later. Replace assumptions with relevant observations as evidence develops. A mathematically coherent plan is still a scenario, not a promise of hires.
A worked application
Fictional example: Two starts at a 50% offer-to-start assumption need four offers. At 40% interview-to-offer, that needs ten interviews; at 25% conversation-to-interview, 40 conversations; at 20% contact-to-conversation, 200 contacts. If offer-to-start falls to 25%, the required upstream work doubles under the same other assumptions. The leader checks whether the team can support that work before setting a commitment.
Common mistake to avoid
Do not import an internet conversion rate as if it were your own calibrated forecast. The role, source, definitions and timing may differ.
Work through the case
FICTIONAL SCENARIO
A two-start goal with a 50% offer-to-start assumption needs four offers. At 40% interview-to-offer it needs ten interviews, before accounting for timing and capacity.
Make it practical
Use the pipeline builder to compare a base and lower-conversion scenario.
Compare your reasoning with a worked response
Show how the assumptions change required activity. A mathematically possible plan may still be operationally unrealistic if the team lacks interview capacity.
Takeaway
Use the method to explain your decision, identify what you still need to verify and choose an accountable next step.
Treat the response as a model for reasoning, not the only possible wording. Adapt it to the role, evidence and appropriate organizational guidance.
