You are failing at product management if...
You treat your job as an exercise in “managing chaos”
You primarily interact with engineers all-day
You believe your primary activity is gathering and documenting requirements
Instead, great Product Managers…
Mitigate chaos by having strong, reasoned opinions about a narrow set of target customers, use cases, and problems
Coordinate and align all functions in the business
Use narrowly defined problems and insights to generate requirements for all functions
