Power BI isn’t there to “make data look pretty” but rather to deliver specific insights and answer specific business questions from the intended user base. So the starting point for analytics is to identify the audience, their questions, associated logic and “slice and dice” attributes that are required to deliver those insights. This is a non-technical exercise focused around gathering requirements and conceptually designing a semantic model that will form the foundation of your reporting and modelling solutions.
You will come away from this session with an approach and templates (which you can immediately use for your own use cases!) to capture stakeholder requirements for report and translate these into a data structure (semantic model) required for Power BI.
