Whenever I receive a question to choose the most cost effective capacity for a certain scenario, I find it difficult to answer because the documentation doesn't give for a beginner good guidelines and I dont understand what Microsoft expects. Most of the time you get a scenario of a fictive organization which has x users needed for Power BI and Fabric and some additional requirements.
How would you answer certain questions? Which considerations do you make? And could that be visualized in a decision tree?
