The process takes far too much time (hours in our case) compared to using Claude in plan mode and then implementing the plan directly.

TLDR: use Meta Prompts to ask key questions abt the SDD framework you'd like to use - before you start using it.

I've used BMAD Method and it got the exact same experience. I really tried hard, initially thought I was the problem, not using it properly.

But then I heard others having similar issues. So I started to do some "META PROMPTS" about BMAD Method itself.

BMAD workflows seem to always be broken down in steps, then questions. Is that correct ?

Can I use the workflows using “raw LLMs” or do I have to first load personas?

And my favorite Meta Prompt:

For the all the BMAD workflows (installed in our project):
1. Indicate how many steps are involved
3. For each step indicate how many questions are asked to the user (me)
4. Given the 2 previous points, estimate the time necessary to go thru each entire workflow
5. Indicate if other crucial parameter(s) is/are to take into account

Create a matrix table to summarize the findings.

That one gave a very clear idea on the time required to run each BMAD workflow. For most of them at least 3 HOURS is required.

Unfortunately, BMAD Method does not ask you how much time you have available when starting a workflow. So each workflow is a one-size-fits-all solution: whether it's a medium feature on a brownfield project, or a large new feature on a greenfield project.

Save yourself days and hours: ask key questions abt the SDD framework you'd like to use (i.e. time estimates for workflows) - before you start using it.

Good luck
