Rethink the work. Then choose the tools.
Faster code generation is useful only when the surrounding delivery process can turn it into value.
Follow a change from idea to release
Map how a request is clarified, implemented, reviewed, tested and shipped. Include waiting time and handoffs. The longest delay may happen well after the code is written.
Keep judgment explicit
Define who owns the intent, acceptance criteria, risk and release decision. Decide which steps can be automated, which need review and which require a person to act. Make those boundaries visible in the workflow.
Measure the whole path
Track the outcome the team is trying to improve. Cycle time, escaped defects and cost per accepted change can be useful starting points. Pair speed measures with quality so a local gain does not hide a downstream cost.
Change one workflow first
Test a bounded redesign with one team. Compare it with the baseline, capture what improved and what became harder, then decide whether to expand, revise or stop.
