Syllabus

What this subject covers, section by section.

Product Discovery & User Research
  • Framing a problem before proposing a solution
  • Interview technique, and the questions that produce useless answers
  • Jobs-to-be-done as a lens on why a customer switches
  • Sizing an opportunity honestly, including when not to pursue it
Prioritisation & Roadmapping
  • The common frameworks and the failure mode each one has
  • Sequencing work when everything is genuinely important
  • Saying no in a way that survives the follow-up conversation
  • Communicating a roadmap without promising dates you cannot hold
Metrics & Analytics for PMs
  • North star metrics against guardrail metrics, and why you need both
  • Designing a funnel that answers a question rather than filling a dashboard
  • Reading a cohort chart and knowing what it cannot tell you
  • How a metric gets gamed once a team is measured on it
Experimentation & A/B Testing
  • Writing a hypothesis that a result can actually falsify
  • Sample size and duration before the test runs, not after
  • What statistical significance does and does not license you to say
  • When an experiment is the wrong instrument entirely
Technical PM Fundamentals
  • APIs as a product surface, not an implementation detail
  • Enough of the database model to reason about what a change costs
  • Latency, caching and the trade-offs behind a 'simple' feature
  • Talking about system constraints with engineers without pretending to be one
Stakeholder & Executive Communication
  • Narrative writing, and why a document beats a deck for a decision
  • An executive update that reports the state rather than defending it
  • Disagreeing with a senior stakeholder and keeping the relationship
  • Influence without authority, which is most of the job
Pricing, Packaging & Monetisation
  • Pricing models and what each one assumes about the customer
  • Measuring willingness to pay before setting a number
  • Designing tiers that make the upgrade obvious
  • Migrating existing customers onto new pricing without churning them
Product Strategy & Positioning
  • Market sizing that stands up to being questioned
  • Competitive analysis beyond a feature comparison
  • Differentiation, and the difference between a feature and a position
  • Why a strategy is not a plan, and what happens when it is treated as one
