How Do You Approach a Needs Analysis?

I'm a huge believer that needs analysis is crucial to efficient and effective instructional design... but I'm a very process driven person! I work predominantly in projects and have devised a master TNA spreadsheet that is adaptable to the size and requirements of a project. In my organisation we have a collaborative relationship with the Change and Delivery & Implementation teams, and we have run a comprehensive joint instructional design discovery session with key stakeholders from the project and the business to ensure alignment from kickoff. For smaller requests from the business, including digital uplifts, I've adapted this to a 2 page word doc. We have seen it reduce creation time as well as iterative changes required at governance from unclear objectives and requirements. I favour Cathy Moore with her very practical approaches to this issue.
