Speed matters in a product's first release, but speed does not mean building without boundaries. Small decisions define a team's future room to move.
A good component boundary is more than folder structure. It explains where responsibility begins and who is allowed to change which data.
Modularity is not fragmentation. It keeps things that change together close, while separating areas that evolve at different speeds through clear contracts.
A strong digital decision begins where technical possibility meets a real user need.
