Operation that uses software developers not as code monkeys but actual business problem solvers that have also business knowledge.

Operation that delivers features instead of burning budget on discussions.

Operation that uses test/acceptance environments where you deploy and validate the design so people actually see the outcome.

Obviously you have to write down the requirements - but writing down requirements is not design phase.

Design starts with idea, is written down to couple sentences or paragraphs then turned into code and while it is still on test/acceptance it still is design phase. Once feature goes to production in a release "design phase" is done, implementation and changes are part of design and finding out issues, limitations.
