Bob Walsh and I are writing a series on Productivity for Programmers, which started with his article Productivity for Programmers, #1: Trusted Systems. In it he identified five trusted systems every programmer should have: Tasks, Decisions, Version Control, Code Snippets, and Bugs. I like Bob's break down (no, not the psychological one resulting from writing "Clear Blogging" - different story), so I want to talk about a related characteristic - Efficiency vs. Effectiveness.
Efficiency
The trusted systems are important, and they are about doing things right, what Drucker called "efficiency" (see David J. Anderson's article Drucker on Effectiveness for a bit more).
