Individual Assistant
In one line: AI is an extension of the developer's keyboard.
Everyone runs an assistant in their own editor. Nobody knows who uses what, how often, or with which settings. Process, board, and docs stay exactly as they were.
Real, measurable speed. Less boilerplate, faster ramp-up on new languages, a shorter learning curve for juniors.
The gains stay individual and never compound. Ten developers, ten assistants, zero shared learning. The same architectural decision gets explained to AI five times, five different ways.
More importantly, delivery speed barely moves — because writing code was never the bottleneck. Planning, alignment, review, rework, and knowledge transfer are. Level 1 touches none of them.
Start giving AI work, not lines. Not "complete this function" but "add this behavior, write the test, open the PR."
