Five practical observations about dates, first versions, measurement, release size and memory, written as field notes rather than rules.
Designing experiences for millions of people
How product teams think about scale, usability and personalization when the rare case stops being rare.
What happens before a good product decision
Framing, evidence, options, trade-offs and a pre-mortem: the unglamorous work that makes a product decision look obvious afterwards. Illustrated with a clearly hypothetical team.
