Kevin S. Goff – Brief BIO• Developer/architect since 1987 / Microsoft SQL Server MVP• Columnist for CoDe Magazine since 2004,

“The Baker’s Dozen” Productivity Series”, 13 tips on a SQL/BI topic• Wrote a book, collaborated on a 2nd book• Frequent speaker for SQL Server community events and SQL Live!360 Conferences• Email: kgoff@kevinsgoff.net • My site/blog: www.KevinSGoff.Net (includes SQL/BI webcasts)• Releasing some SQL/BI video courseware in the future

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

Small analytic project

• 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

Goals of Analysis• Across time, am I consistently scoring above the conference average?• What are my best sessions overall?• For any events where I performed below overall average, was it just one bad

session or multiple bad sessions?• How am I doing in each of the 6 Evaluation Measures (style and delivery,

subject knowledge, etc.)• 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?

• Are the sessions that I personally like to do, the ones that are most successful in driving conference average?• Overall as a speaker, am I trending upward or downward?• How am I doing in the annual Orlando event, which is considered the big

event of the year?

Am I consistently above overall average?

As a conference speaker, are my evaluation ratings consistently above the

overall conference average?

When I do my two favorites, am I helping?

All other sessionsMy 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

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”)

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

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
