According to Cydney Mar, most founders do not fail because their idea is bad. They fail because they take the right steps in the wrong order. On her Product Development Roadmap page she names four common patterns: jumping into sampling without clarity, choosing suppliers based on guesswork, ignoring margins until it is too late, and trying to figure it out as you go. Each one leads to wasted time, money, and stalled progress.
The pathway answers each pattern with a stage placed before the expensive step it protects. Clarity comes before sampling. Costing comes before production. Supplier vetting comes before orders.
