Chart and reading

Synthetic practice chart

Account for dependencies and separate engineering, design and review weeks.

Challenge your recommendation

What if reviewer capacity, not engineering, is binding?

Guardrails: Proposed estimates, no effect size or confidence probability; high reach is not a forecast.

Next evidence: Actual capacity, range estimates, demand evidence and opportunity cost.

PRD sections: 1, 4, 16. Open proposed PRD

E21 · Choose feasible scope

Decision: Which opportunity fits actual capacity?

Readout: Account for dependencies and separate engineering, design and review weeks.

Actual query output (synthetic), first rows:

opportunity_id name eng_weeks design_weeks review_weeks dependency low_reach high_reach source_id
OP1 Explain entitlements before render 2.2 1.1 0.3 50 180 PLAN
OP3 Webhook recovery and reconciliation 3.3 0.4 0.6 15 85 PLAN
OP2 Version-bound locale review 4.1 1.5 1.4 OP1 30 120 PLAN

Model spoken answer: I would fund one bounded workflow and name what is deferred, after checking all constrained roles.

Caveat/counterargument: What if reviewer capacity, not engineering, is binding? Proposed estimates, no effect size or confidence probability; high reach is not a forecast.

Next evidence: Actual capacity, range estimates, demand evidence and opportunity cost.

Deliberately left out: Treating person-weeks as a calendar completion promise.
