Many years before Power BI, there was Power Pivot. (Bonus points for you if you remember that back then that it was known as PowerPivot.) I remember attending a Birds of a Feather session at Microsoft TechEd to discuss the implications of Power Pivot with a group of data professionals. There was much gnashing of teeth over the perceived horrors of putting data directly into the hands of users. Then, at the back of the room, a very relaxed gentleman, with flowing locks and wearing a Hawaiian shirt and Birkenstocks, suggested in the most soothing of tones, “Hey man, just let the data be free!”

I’ve never forgotten that scene and how it epitomized both the goals and challenges of self-service business intelligence. On the one hand, the self-service ideal is to free up data to empower users to discover and use information in insightful ways. On the other hand, there are legitimate reasons to control how people access, use, and share data.

Whereas traditional BI imposes many important controls on the structure, composition, and consumption of data, the process often had difficulty keeping up with the speed of business. While self-service tools can accelerate the development and delivery of information to users, the lack of controls had reintroduced the very problems that traditional BI was supposed to solve: incomplete and inaccurate data, inconsistent calculations, hard to repeat processes, and multiple versions of the truth. In short, chaos.

If you’re currently using Power BI and find yourself facing these very problems, what can you do to conquer the chaos? Implement a data governance strategy that strikes a balance between an IT-managed information solution and user-driven exploration of data. Fortunately, Power BI has evolved over the years since its initial incarnation as Power Pivot to include many features that can support your data governance goals.

Data governance is a huge subject area and a specific implementation approach is dependent on many factors, including organization size, user skills, types of data in use, and the self-service tools available, to name a few. My intent today is not to provide a comprehensive overview of data governance in Power BI, but simply to give you a starting point for your own implementation strategy with specific tactics that leverage features in Power BI for better data governance.

One of the most important goals of data governance is to ensure that the data in any shared spreadsheet, report, or dashboard is complete, accurate, and consistent no matter what. That’s a lofty goal to try to apply to all data assets in an organization. Instead, make a distinction between shared data assets for organizational or departmental use and other data assets that are developed for personal exploration, and then set up policies and processes that support both use cases. That way, users can work with the data they feel is appropriate for the question at hand, but can also easily identify sources that have been officially approved. Importantly, users should be trained in the policies related to the certification process and understand how the content they create should be used and shared.

Towards this end, consider the following actions:

• Provide users with a sandbox environment in which they can combine data sources that they are allowed to access and experiment with different types of calculations or different ways to present the data.

Power BI has always included the components necessary for a sandbox environment, regardless if users choose to work in the desktop application or in a browser accessing the Power BI service online. Each user can work in an isolated space and has complete freedom to access a wide variety of data sources, whether certified or not.

If the content is saved or published to the Power BI service, it stays within the user’s personal environment called My Workspace. The user may later decide to share the content with others in a few different ways, as described in ways to share your work. You can control whether, and how, content can be shared in the Tenant Settings page of the Power BI admin portal.

• Assign oversight responsibility to at least one individual per department or subject area. This individual, commonly known as a data steward, reviews data sources, validates report logic, watches for and eliminates duplicative efforts, and promotes approved content from a sandbox environment to a shared location, among other tasks. In addition, the data steward determines who has access to the promoted content.

Power BI uses app workspaces to organize content. You can think of an app workspace as the logical equivalent of a shared folder on a server. Consider creating separate workspaces to differentiate between certified and non-certified content. Within a workspace, assign individual users or groups to appropriate roles that control access and also define the types of content creation and management activities they can perform.

For users who only need to consume the content created by others, all items or a subset of items, can be published from an app workspace as an app, which insulates users from any ongoing content changes in the originating app workspace. In other words, the app is purely for end user consumption, whereas the app workspace is the collaborative development environment.

Ideally, data stewards should have the ability to move content between app workspaces when promoting content to a certified status. However, Power BI does not yet support this capability. Until this feature is added, the creator’s content in a PBIX file must be published to the target app workspace. As long as you have edit access to a report (among a few other limitations), you can download its corresponding PBIX file from the Power BI service and then republish it to a new location.

• Monitor activity and usage by content and by user. Usage auditing ensures compliance with policies and standards, and surfaces potentially valuable new data sources that might be of use to a broader audience.

Power BI provides the following options for monitoring:

Usage metrics. You can review data for dashboard and report usage from a built-in report or you can use a live connection to the underlying data source for these metrics if you prefer to build a custom report.

Audit logs. You can access audited activity details through the Office 365 Security and Compliance Center, or by executing a PowerShell script.

When you take advantage of Power BI’s features with data governance in mind, you can make chaos a relic of the past. Instead, users can make better decisions because they are using higher quality content and more trustworthy data. A cooperative governed environment reduces duplication of effort inherent when users work in isolation and thereby improves everyone’s productivity. And you have a better oversight of how data assets are being used–or not being used–and can intervene where appropriate.
