Publishing content to the Power BI Service is just the beginning for so much of the content that you will produce. It becomes important to understand that there are some real issues that you can get yourself into if you don’t think through how best to manage them.
PBIX files are the central unit for Power BI, there is no easy way to get it right on day one. Take solace though, as there is always a fix. Splitting your PBIX files into Data model and Report(s) is an excellent starting point, then starting to think through your sharing mechanism to use use “Teams” as the unit of sharing combined with Power BI Apps, rather than Workspace access. Once you get these things in line you’ll find Power BI simple to manage and maintenance a breeze.
