Build PM Disciplines Daily — Free →Shipping features without outcome metrics

Jumping to solutions before defining the user

Treating user requests as a roadmap
→ Requests are data — filter through strategy and impact first
Saying yes to every stakeholder ask
→ Every yes is a no elsewhere — make trade-offs explicit
Writing vague PRDs
→ Specific problem, specific users, specific success criteria
Ignoring guardrail metrics
→ Primary winning + guardrail breaking = regression
Blaming engineering for slow delivery
→ Your scope and requirements are at least half the cause
Hiding bad news until it's crisis
→ Surface risks early — small escalations beat large surprises
Using 'we' to hide personal accountability
→ Own decisions in first person — 'I decided X because Y'
Not dogfooding your own product
→ Use it daily for its real purpose — notice what users notice
Over-meeting, under-writing
→ Default to async docs, use meetings only when decisions require them
Treating retros as ritual, not improvement
→ Every retro ends with named owner + deadline for each action
5 Places to Spot Anti-Patterns in Yourself
Your own calendar — 80% meetings and 20% writing is a weak-PM signal
Your PRDs from 6 months ago — if they're vague, fix the template
Recent launches — did you actually move the metric you promised?
Feedback from engineers/designers — if they feel unheard, you're not listening
Your manager's review — patterns in their feedback reveal your biggest anti-patterns
5 Ways to Change Them
Pick ONE anti-pattern to work on per month — trying to fix all fails
Tell your manager and a peer you're working on it — accountability accelerates change
Audit at end of month: did you catch yourself? Did you correct it?
Build a replacement habit for the bad one — not just removal
Expect 3–6 months before a new habit sticks — be patient with yourself
FAQ
How do PMs recognise anti-patterns in themselves?
Ask a peer you trust to give you honest feedback. Self-assessment is always kinder to yourself than reality. The peer feedback will be uncomfortable but accurate. Another signal: which anti-patterns on this list feel uncomfortable to read? Discomfort often means accurate — worth sitting with.
What's the single worst PM anti-pattern?
Shipping without outcome metrics. Everything else is recoverable. A PM who never commits to outcomes never learns from results — and doesn't improve. This is the single habit that separates PMs who plateau early from PMs who grow into senior roles.
