How We Got There
And why should I care?
Microsoft has been in the BI space for a long time with a “traditional IT”
focus
• Think SQL, OLAP, multi-dimensional, enterprise IT, data warehouses
Circa 2007-14 MSFT seemed to leave the world move to SaaS without
putting much of a fight
• They let the likes of Salesforce, Google, or Tableau, make them look old and irrelevant
And lots of moving parts took time to mature and gel
• Power Pivot was first launched in 2009 but was relegated to add-in status until Excel 2016
• Power View/Silverlight dead-end (mobile anyone?)
But since 2015 there has been a strong move to inexpensive yet
powerful desktop + cloud + mobile services for business users
• Think tabular, spreadsheets, SaaS, end-user friendly, within reach of smaller teams without
requiring IT
Come 2017: still work in progress, but a compelling offer
• Strong momentum behind Power BI (PBI) makes it unlikely they will drop the ball, so worth
investing into its vision
• Good old Excel has become a formidable yet more accessible tool, aka “Modern Excel”
“Windows Only”

Exec Summary: Lots to Like, Some Drawbacks
Strengths
• The broadest BI/DB stack of any
vendor, with individual components
strong in their own right.
• Builds up on established leading
products (Excel, O365, SQL Server,
Azure).
• Vibrant product development, iterative
and interactive.
• Strong user community, support,
learning material.
• Easy and cheap to get started.
Weaknesses
• Hard to keep up with all the moving
parts and updates!
• Still somewhat Microsoft-centric, but
much less so than in the past.
• Not as good as Tableau for more
sophisticated interactive charts.
• A lot of stuff still in beta/incomplete.
Needs another 12-18 months of
maturation.
• Licensing can get complicated, some
market segments feel neglected.

in PBI too, usually within about an hour.
PBI Desktop Excel Desktop Data model Analyze in Excel, Use
PBI Desktop as a

Since users will need to refresh the dataset, and refresh for external connections is not supported
in Excel Online, it’s recommended that users open the workbook in the desktop version of Excel on
their computer.

Confusion Infusion: MSFT Loves to Move, Rename Features
Excel 2010: It’s Coming from the SQL Team, So Let’s Hide It
• PowerPivot introduced as an Excel add-in, common engine with SSAS Tabular
• In-memory engine introduced as Vertipaq then rebranded to xVelocity, because why not?
Excel 2013: Moving Sideways
• Power Pivot (now with a space, no product name can be left untouched!) remain as an add-in
• Introduction of Power View and Power Map based on Silverlight dead end
• Introduction of Data Explorer then rebranded as Power Query (notice a trend here?)
Excel 2016: Finally Embracing the Power
• Power Pivot is its own ribbon tab but also accessible from Data > Manage Data Model
• Power Query renamed as Get & Transform
• Power View hidden though still available, Power Map renamed to 3D Maps
• Old way to get external data continued to coexist with Get & Transform until March 2017
Power BI Desktop: There Can Be Only One Power Something
• Power Query found as Home > Get Data (but some documentation does talk about “Power Query”)
• Power Pivot found as the Modeling ribbon tab (let’s not name it “Power Pivot” because it might look familiar to Excel users)
PBI Service: Office Or Not?
• “Power BI for Office 365” was an older version of the service using Excel (with Power View/Map) for authoring and was deprecated at the end of 2015. But
powerbi.com user management continues to rely on O365.
Azure: What’s Up with That?
• Retirement of DataMarket, Data Services, Reporting Services
• Planned merger of PBI’s data catalog with Azure Data Catalog

Great Momentum, But Uneven Features Between Products
• Streaming datasets launched Jan. 2017 in PBI Service, not available in PBI Desktop
• Can’t print or export to PPT from PBI Desktop
• Some mapping features only available in Desktop (ARCGIS) or Service (aerial basemap)
• Many online services and CDM as a native Source in PBI but not (yet?) in Excel 2016
• Calculated Tables, Bidirectional cross filtering available in PBI Desktop, not in Excel 2016
• Some UX pieces offer better QoL to author DAX in Excel than Power BI
• OneDrive listed under Get Data > Files in PBI Service, but not Desktop
• Some objects such as Hierarchies recognized in Excel’s data models but not in PBI Desktop
• Excel imports/exports M queries to ODC files but PBI Desktop doesn’t
• No Dashboards and no natural language Q&A in PBI Desktop / PBI Report Server
• Need to install a separate “PBI Desktop for Report Server” for On Premises work
• SSDT in VS2017 not available at launch
Don’t despair: lots of monthly updates, many parts still in beta/preview (e.g. most SaaS connectors)

Even More Caveats: “Pulling a Microsoft”
Some questionable choices
More Open but Still Somewhat MSFT-centric
• Authoring limited to Windows and to a smaller extent browser
• No Mac desktop
• Flow/PowerApps connectors still focused on MSFT world
• SQL, Sharepoint, Azure
Abrupt & Enterprise-Focused Licensing Changes
• Changes to Free/Pro announced out of the blue within less than a month of their
enactment
• 1-year free Pro trial thrown in to help you stomach it
• PBI Premium starts at $5K/mo
• Makes sense only from 500+ users
• Forced migration from PBI Embedded (Premium Embedded pricing starts at $625/mo)
• Why tie PBI Report Server to PBI Premium and SQL Server Enterprise with Software
Assurance?
• SMEs and ISVs Might Want On-Premises PBI…
