Per Axbom discusses the importance of being flexible and adapting when designing solutions. He provides three examples where stopping the current design approach and exploring alternatives led to better outcomes for the business. The key lessons are to follow the goals of the business over the goals of any individual project, use new information to create more efficient solutions, and recognize that numbers and metrics should guide design decisions over sticking to any predetermined path. Design is about continuous optimization, not picking a single path at the start.
