Power BI Life cycle Management
This blog entry describes a way to achieve a DEV, TEST and PROD environment in power bi as well: http://angryanalyticsblog.azurewebsites.net/index.php/2016/04/17/power-bi-content-workflow/
So in a corporate Power BI environment, I currently think you basically have the following options: Let you end users access reports and dashboards through content packs or throught a PROD group workspace (with privacy set to members can only view Power BI content).
With content packs you can include just the content that fits your user profile, but if they for example need access to a lot of reports from multiple business areas (ie. TEST workspaces) it gets messy in their personal workspace, since the separation is not visible in their personal worspace. Another difference is that with content packs, the end user can create a copy of the reports and modify it.
You can check this whitepaper that describes governance in PowerBI..This is the most complete so far
