My memory for fine details is a sieve, and I don&rsquo;t trust myself not to skip documenting a step. Forcing the workthrough through the source code management system may slow me down in the short term, however, provides long term benefits. The challenge is in building enough of a skeleton that projects 2, 3 and 4 are faster. The great thing about AI is with a valid skeleton the projects are greatly accelerated.</p>
