3. History of Microsoft Self-Service BI Power Pivot – Excel Add-in as part of Excel 2010 Vertipaq Technology (later renamed xVelocity) utilized columnstore index compression to create in-memory “mini-data-cubes” that could cover 20 million+ rows Power View – Excel Add-in for report visualizations SharePoint Integration in 2013 to deploy Power Pivot / Power View Content And then came Power Maps/Power Query as add-ins Power BI for Office 365: could deploy content from these add-ins to an Office 365 “Sharepoint Lite” site: no need for SharePoint on-premises And now: Power BI Service (Power BI 2.0) Complete standalone tool with components of Power Pivot, Power View, Power Maps, and Power Query “baked in” No longer depending on other product groups and release cycles No longer tied to Silverlight dependency that comes with Power View and Sharepoint (makes it hard to consume from non- Windows devices) Free and frequent updates: no dependencies on other products https://powerbi.microsoft.com/en-us/ Power BI custom visuals: https://app.powerbi.com/visuals/https://app.powerbi.com/visuals/

4. Customer Perspective of a Balanced Scorecard Four major areas (perspectives) of a Balanced Scorecard Financial Perspective Business Process/Internal Processes Customer Perspective (Medical surveys, student/customer surveys) Learning and Growth/Employee Training/Innovation Issues with any Perspective Quality of Data Does the analysis accurately model the process? Analysis 101: So What?

5. Small analytic project – something beyond AdventureWorks From 2012 to 2015 I spoke regularly for the VS Live/SQL Live conference brand Spoken at 8 conference events (Orlando, D.C., Vegas, etc.) Have delivered 11 different sessions (some several times, some just 1-2 times) 6 Evaluation Measures, scored from 1-5 Stored in Excel spreadsheet, about 300 rows Spreadsheet contains my scores, plus overall conference average One shortcoming: I don’t have individual evaluation sheets. If 30 people attended a session, I only receive the average scores for the 6 measures – not the individual score for each person. Makes it more difficult to identify any outlier scenarios

6. Loading of Data New measure to calculated weighted score Can load data from Excel, from SQL Server, from many sources For relational data, Power BI has modeling capabilities to create relations For this example, we’re using a spreadsheet (Power BI will load in data) We need to create a Measure to calculate a weighted average score A question – should we use a weighted average or a straight average? Session 1: 30 attendees, average score 4.9 Session 2: 7 attendees, average score 4.7 Is the overall average… 4.8 (straight average of 2 sessions) 4.84 (weighted average)

7. Goals of Analysis 1.Across time, am I consistently scoring above the conference average (and therefore helping to drive it up)? 1.Related - overall as a speaker, am I trending upward or downward? 2.For any events where I performed below overall average, was it just one bad session or multiple bad sessions? 3.How am I doing in each of the 6 Evaluation Measures (style and delivery, subject knowledge, overall rating, etc.) 1.The conference organizers/management feel that the “overall” evaluation measure is the most important of all. So am I consistently helping to drive up that average? 4.Are the sessions that I personally like to do, the ones that are most successful in driving conference average? 5.How am I doing in the annual Orlando event, which is considered the big event of the year? 6.What are my best sessions overall?

8. Am I consistently above overall average? As a conference speaker, are my evaluation ratings consistently above the overall conference average? Quick trend visual

9. When I do my two favorites, am I helping? All other sessions My favorite 2 sessions Average is higher when I do sessions I like BUT…I’m higher above the average when I do the other sessions

10. How am I doing in the “Overall rating”? For the Metric of “Overall Rating”, how am I doing compared to the overall conference average? Can click on a bar and the rest of the page refreshes (“cross-filtering”)

11. How am I doing at the Orlando event? Drove up the overall average three of the four years For the most part, an overall ascension in score, and most recent of 4.68 is highest Overall, drop up score by two-tenths of a point

12. What are my best sessions? One of my two favorites For that session, I’m consistently above my overall averages in every metric These four are almost identical
