Engineering quality is invisible until it fails. Systems that were built quickly become expensive to change. Teams spend more time working around technical debt than building what users need next.
A common failure mode: engineers implement specifications without product context. The code works. The feature ships. But the architecture does not support the direction the business is heading , and every subsequent change costs more than the last.
Another pattern is handoff. Strategy in one room, design in another, engineering in a third. By the time code is written, the reasoning behind decisions is lost. Trade-offs get made in isolation. The product drifts.
