Self-Service BI
![Page 6: Balanced BI Approach (Power Pivot & SSAS Tabular)](https://reader034.vdocuments.net/reader034/viewer/2022042623/549a080ab47959234d8b4570/html5/thumbnails/6.jpg)
Also known as Organizational BI:

• Analysis Services (SSAS), SQL Server Integration Services (SSIS), etc.
• Runs on server hardware
Corporate BI
![Page 7: Balanced BI Approach (Power Pivot & SSAS Tabular)](https://reader034.vdocuments.net/reader034/viewer/2022042623/549a080ab47959234d8b4570/html5/thumbnails/7.jpg)
• Spreadmarts are what commonly take the place for Self-Service BI in an organization.
• Unraveling linked spreadsheets into a formal requirements spec takes a lot of time
• Not always a success; things get lost in translation.
• Process can take months for an organization to complete without producing any results.
• Gap between Excel knowledge and OLAP tools is huge.
Common Situation

![Page 9: Balanced BI Approach (Power Pivot & SSAS Tabular)](https://reader034.vdocuments.net/reader034/viewer/2022042623/549a080ab47959234d8b4570/html5/thumbnails/9.jpg)
Self-Service (Scooter) or Corporate (Super Bike):
• PowerPivot (64 bit) can handle hundreds of millions of records.
• Threshold is memory on your desktop / laptop (4-16 GB memory)
• SSAS Tabular runs on server hardware (512 GB memory)
• Partitions for incremental loading, perspectives, security roles.
The Ever Important Choice
![Page 10: Balanced BI Approach (Power Pivot & SSAS Tabular)](https://reader034.vdocuments.net/reader034/viewer/2022042623/549a080ab47959234d8b4570/html5/thumbnails/10.jpg)
• PowerPivot and SSAS Tabular are almost identical.
• Both use DAX (Data Analysis Expressions)
• Calculated Columns, Measures, etc. are compatible
• There is not a huge gap between Excel and OLAP any longer
• Excel became more advanced, OLAP’s entry point became less advanced.
Similarly Different – What?

Prototype with PowerPivot:
• Provide the data to business users in a sample PowerPivot workbook
• Simple calculations, measures, KPIs as examples
• Educate business users on how to use PowerPivot to their advantage
• Iteratively educate them on DAX (Especially CALCULATE!)
• You can import a PowerPivot model into SSAS Tabular!
You Can Use Both…and You Should!

Success Factors:
• User Adoption – If users had a hand in creating it, adoption will be a success.
• Training – Each BI solution requires training and users will get it from the beginning.
• Time to Market - Requirements process is not disconnected; its small
• Users will speak your DAX language over time as its close to Excel!
Why Use Both?
