📘 CASE STUDY — Part VIII: Turning Vague Requirements Into a Shipped System
SECTION 0 — SCENARIO
PM says:
“We need better onboarding.”
No metrics. No clarity. High urgency.
Senior execution means converting ambiguity into delivery without chaos.
SECTION 1 — CLARIFY THE OUTCOME
Ask:
-
what metric moves? (activation, retention)
-
what is success in 30 days?
-
what’s out of scope?
Define a measurable goal.
SECTION 2 — DESIGN DOC (SMALL, FAST)
Write 1–2 pages:
-
hypothesis
-
user journey
-
constraints
-
proposed changes
-
risks + rollout
SECTION 3 — SLICE THE WORK (SAFE INCREMENTS)
-
instrument first
-
ship UI copy + flow improvements behind flag
-
add backend changes if needed
Senior rule:
Ship the smallest thing that validates the hypothesis.
SECTION 4 — LAUNCH + MONITOR
-
feature flag
-
dashboard ready
-
rollback plan
SECTION 5 — EXERCISE
Write the design doc you’d send:
-
problem
-
metrics
-
rollout
-
how you’ll know it worked
