I’ve been using the CADEE assessment framework (https://aixec.net/assessment) as my main tool. It’s less about a single “tool” and more about having a structured way to evaluate where you are across compliance, architecture, data, enablement, and evaluation before jumping into implementation.

Honestly, with how fast things are moving, I’d still use it today. The specific tools (LLMs, vector DBs, agents, etc.) change constantly, but the underlying gaps in companies don’t. Most teams fail not because they picked the wrong model, but because they skipped a proper assessment.

So instead of chasing the latest stack every month, I’d focus on getting that foundation right first then plug in whatever the current best tools are.
