4. Brief History of Power BI and Tableau

5. Brief History of Power BI and Tableau
Power BI
• Power BI was originally developed by Microsoft’s SQL Server Reporting Services Team in 2010 under
Project Crescent and available for download as a bundled package with SQL Server’s Codename Denali.
• Power BI was released by Microsoft in September 2013 as Power BI for Office 365 and has since evolved
with many other feature sets and related functionality.
Tableau
• Tableau was founded in January 2003 and experienced substantial growth through 2013.
• In May 2013, Tableau took the company public in an IPO on the New York Stock Exchange that raised
$250 million dollars.
• In 2015, Tableau, after five consecutive years of profits, their 2015 year-end results showed the company
lost $84 million.
• In June 2018, Tableau acquired Empirical Systems, an artificial intelligence startup, with the goal of
integrating its features into its overall platform. with plans to integrate the company's technology into the
Tableau platform.
• In June 2019, Tableau was acquired by Salesforce in an all-stock deal worth over $15 billion.

9. Performance and Functionality of Power BI vs. Tableau

10. Power BI vs. Tableau Interface
EPC Group is one of North America’s leading Power BI integration and development firms, but the content
and data presented here in this webinar is based off of the hundreds of conversations I have over the course
of months and the past few years with key stakeholders and IT decision makers at organization’s all over the
globe. This includes my personal testing and review of reports from both platforms. A few main points that
come up time and time again are:
• Tableau does not have the type of web support that Power BI provides and especially now that Microsoft
has made their announcement regarding Azure Analysis Services (AAS) being included with Power BI
Premium accounts (which you can get for $20 / month / user) which is a game changer.
• With Azure Analysis Services (AAS), you are able to throttle up the cores in the cloud, which vastly
outpace the performance of any desktop bound CPU, whether you're comparing it to Power BI Desktop or
Tableau desktop to handle the required data your company is handling to meet your reporting needs.
• With Power BI hosted on the Azure platform, it is absolutely far more scalable than Tableau and with
Power BI, you are much more in charge of the environment’s backend.

11. Stack Overflow Questions Tableau vs. Power BI

12. Stack Overflow Questions – Tableau vs. Power BI

13. Power BI vs. Tableau Interface

14. Power BI vs. Tableau Interface
The debate over the ease of use and ability for end-users and/or Power Users to learn Power BI or Tableau
has really ended as 80% of the client feedback I get on calls from CIOs, IT Directors, Directors of Business
Intelligence or even stakeholders responsible for training their organization’s end users all give me the same
story.
• Power BI’s interface is much easier to learn
• It is a part of the overall Microsoft / Office 365 stack and the built-in SSO (Single Sign-on) capabilities
allow for a much more fluid experience
• Tableau resources are much harder to find as well as much more expensive so the training as well as
the “report updating” and new project aspect of growing the existing environment and then the related
knowledge transfer to the client becomes much harder and more labor intensive
• For a pure apples to apples comparison (i.e., compare the computational power of Tableau Desktop vs.
Power BI), the performance is nearly identical and comes down, not to the application in question, but to
your local machine's CPU. That is where moving into the cloud becomes significant, because there is a far
better price to performance ratio in Power BI Premium (i.e., the cloud on the Microsoft Azure platform)
vs. Tableau Creator (the cloud).
• Tableau is used by analysts and experienced- users mostly use for their analytics purposes and Power BI is
used by both naive and experienced users.

15. Power BI Governance Model vs. a Tableau
Governance Model

16. Power BI Governance: Easier to Create
• Data Sources
• What are the suggested data sources? | Suggested connection mode? (To your users…)
• Why would certain data sources be restricted?
• Power BI Service | Power BI.com
• What are your licensing policies?
• The use of App Workspaces?
• The use of content packs?
• Power BI Report Creation
• Power BI Desktop client distribution and its ongoing updates
• How are PBIX files handled? Where are they stored? Any naming conventions? Version history?
• Governance around desktop client updates for external users or remote workers?
• What are your policies around using custom visuals?
• Ensuring strict and clearly communicated development practices

17. Power BI Governance: Easier to Create (Continued)
• Data Model Usage | Reports
• What is your mobile and/or tablet strategy on distribution as well as management and usage?
• What integrations to you allow? | What are your report embedding policies or practices?
• Gateway Management and Ownership
• Do you have repeatable processes for configuration as well as monitoring?
• Scheduled Reviews and Updates to Your Power BI Governance Strategy
• This must be developed and all key Power BI stakeholders must read it and acknowledge it
• A clear escalation path must be established and defined in your organization’s governance strategy
• What data sources are allowed and documented specific to your organization?
• Excel, SQL Server, SharePoint, CSV, Microsoft Azure-based, other databases, SaaS-based, App APIs
• Dynamics 365, SAP, Enterprise Data Warehouse, Oracle, etc.
• What is Your Power BI Power User Strategy?

18. Power BI: Power User Strategy

19. Power BI Power User Strategy: A Silver Bullet
 A Successful Power User Strategy Can Make Or Break Your Power BI Implementation
You can need to:
 Setup and champion an internal Power BI User group for your organization
 Provide monthly training to your organization’s Power BI users from any and all departments
 This needs to be recorded and uploaded to Microsoft Stream, SharePoint or MS Teams
 Create a training curriculum from these monthly training courses as users will be able to take “refresher courses”
 New employees can start watching these Power BI videos as part of their onboarding to the organization
 Provide users with links and videos to documentation and tutorials
 They should maintain a SharePoint Site or MS Teams channel to store these “best practices” and lessons learned
 Help to identify possible “additional” or “future” Power BI Power User candidates
 As the Power BI implementation grows, additional Power Users will be required
 Be the first line of defense in taking complaints about any performance issues or data quality issues

20. Power BI Power User Strategy: A Silver Bullet (Continued)
 Power users can help answer everyday questions from a business perspective
 Examples of questions they can assist in answering, without “IT Speak” are:
 How can I get a Power BI Pro licenses and why don’t I have one already?
 They need to be prepared to answer this very loaded question that can cause frustration in many cases.
 They can assist in answering questions such as “What would my current Excel report possibly look like in Power BI?”
(Power Users are great advocates for showing the business what is possible)
 Power users should be invited to assist in requirements gathering sessions when new reports are
requested from the business
 When you have an advocate in the room that gives the appearance of a neutral party, and is
assisting in gathering requirements from a new business unit or stakeholder, this goes a very
long way in achieving buy-in

24. Establishing Power BI’s System Governance Model

25. Establishing Power BI’s System Governance: Examples
• Security and Sharing
• How are reports secured and shared? AD Groups and DLs | What about Office 365 groups?
• What are your AD Group policies?
• A clear guide to sharing dashboards in your organization must be established
• System Usage, Monitoring and Auditing
• Utilizing the Power BI Admin Portal

• Create alerts to ensure dataset owners can quickly resolve any issue that arises
• Scheduled specific times to audit actions performed by users in Power BI
• Monitor your gateways and review any errors or excessive memory utilization
Data Freshness
• What are your requirements around data freshness? Does this vary by data source?
• There must be data source owners clearly defined who are responsible for data freshness

26. Developing a Power BI 36 Month Roadmap

27. Power BI 36 Month Roadmap
 Development of a detailed 36-month plan for the organization’s power BI implementation and the
