The document discusses software architecture and some common problems in its creation. It identifies three main issues: a focus on technical solutions over requirements, lack of planning time, and the difficulty of gaining experience as an architect. To address these, the document recommends getting involved early, understanding requirements thoroughly, pairing with others, practicing with architecture exercises, and focusing on important design decisions that are hard to change.

We have a problem...
„So how are we supposed to get great architects,
if they only get the chance to architect fewer
than a half-dozen times in their career?“
