Tell The Joke Again – Blogging On Blogging

I just returned from a meeting with some of my peers at SolidQ and we were talking about the value of blogging and publishing articles.  A few days ago, another one of my peers asked me to review his first-ever blog post before it was published.  Douglas McDowell, CEO of SolidQ North America, shared a blog post he wrote earlier this year about his perspective on this, which I found quite insightful.  It’s about sharing information that someone has shared with you.  I now share this with you:

Tell the joke again

by Douglas McDowell

Have you ever retold a joke? Of course you have, we love to hear jokes and retell them. But no one ever tells the joke the same way they heard it, they change it to reflect their personality, make it funnier or fit a situation or audience better. A part of them comes through in how they retell the joke. And retelling the joke is usually as (or more) entertaining to the person retelling the joke as it is to the people hearing it.

The last few weeks I have been spending a lot of time doing one-on-one meetings with folks on the services delivery team, mostly around their quarterly plans for non-billable contributions and professional development. What a blessing that has been! It is tiring to spend your day in back-to-back meetings, but it I don’t remember when I have gotten to spend so much direct time with our people talking about how to make themselves, and in-turn SolidQ, so much better. The reality is that we all try to pack too much into our days, and it is far too easy to only focus on what has to get done and put off what could get done. But the stuff that could get done—but doesn’t necessarily have to get done—is often what is most valuable: investing in ourselves and SolidQ – the company that lets us do what we love to do.

A reoccurring theme in my quarterly planning discussions has been blogging. What a great way to reflect on who you are, where you are going and what you are finding along the way, and then reinforcing or exploring further your discoveries. Everyone I spoke with agreed wholeheartedly — but almost none of them blog, myself included. Interestingly, a common comment that people volunteered was that they do not feel like they have much new or worthwhile to blog about. Each time I heard this I directly challenged it. I challenged the notion that blogging was for the benefit of the reader… I think blogging takes a completely different form when the writer is a little selfish and writes it for their own benefit. After all, it’s their blog, its their own online journalism column about whatever they want to write about and the reader and “public” aspect of a blog is really just about accountability and sharing oneself with others. Wow, I started that concept with selfishness and ended it unselfishness. Guess that makes my point that I have convinced myself and have been trying to convince others that blogging is a win-win proposition for everyone.

I challenge you to tell the joke again.

Perhaps, if you started blogging today, you would not have a single new thing to tell the world. But I think the world would be worse off if we only told jokes we made up (painful). So… Retell a story. Explain how you figured out something obvious. Announce something exciting. Explain your reasoning behind your perspective. Share your epiphany moment, adding accountability to what you know you need to do next.

Datazen Visual Control Categories

Choosing the right visualization control for a set of data can sometimes be challenging.  I find some aspects of designing dashboard solutions in Datazen on the surface to be very simple but it’s easy to get stuck in the details and fine points.  The purpose of this guide to help simplify and categorize visual control choices in mobile dashboard design.  Datazen supports five categories of visual controls:

  • Navigators
  • Gauges
  • Charts
  • Maps
  • DataGrids

Navigator Controls

These controls are used to filter the data displayed in other controls

image

  • Time Navigator displays a range of time/date values

Supports years, quarters, months, days, hours
Auto-generates each date/time level value (doesn’t require a date lookup table)
Supports one or multiple metric fields

  • Scorecard Grid combines a selection list with multi-field value KPI scorecard
  • Selection List supports single-select, multi-select and All

Gauge Visuals

image

This group of controls display a single numeric field value rather than multiple values

  • The Number control displays a single value with no target
  • All other controls display a value compared to a target value, which requires that the dataset has two separate metric fields for this purpose.

Chart Visuals

image

  • Time Chart & Comparison Time Chart:
  • Similar to Time Navigator but also supports auto, decade levels
  • These controls segment aggregated metrics by a category field:

Category Chart, Comparison Category Chart, Waterfall Chart, Funnel Chart, Tree Map

These controls use multiple metric fields (doesn’t segment)

Totals Chart, Pie Chart

Map Visuals

image

  • Geographic region names map to embedded shape names in the map definition
  • Shapes use well-known region names but not well documented.  All the shape names are exposed in a JSON structure within the dashboard definition file (to view the definition, rename a copy of the .datazen file with a .zip extension.)
  • Single metric field values:

Map, Bubble Map

Metric & comparison (KPI target) values:

Range Stop Heat Map

DataGrid Visuals

image

  • Simple DataGrid:

Based on one table, displays selected fields

  • Indicator DataGrid:

Based on one table, displays selected fields as either columns or indicators/gauges.

Indicators require 2 fields for metric & target/comparison

  • Chart DataGrid:

Supports features of Indicator DataGrid

Based on two tables with matching key fields

Second table is used for the category chart

Power BI, Self-service and Governed Data Solutions

Power BI is due to be released to the masses this week and I’m very excited to see this powerful product made available to so many for so little.  We’ve had some of the capabilities of Power BI in other Microsoft products for a few years so why is this this different and what does it really mean for most business users and IT shops?  I think there are enormous possibilities in this new frontier of easy-access, self-service analytics but there are also big challenges ahead to manage systems with a different style of discipline.

As I visit organizations interested in Business Intelligence and data analytics, and talk to people in the industry about self-service tools; I hear some common and often conflicting themes:

“Business knowledge workers want self-service tools to get answers from reliable data”

“CIO/IT leadership: let’s enable the business users to do their own reporting and analysis so our IT staff can do other things”

“Data should be centrally-managed by IT and DBAs so there is one version of the truth and the data can be secured and maintained”

“Self-service BI empowers everyone in the business to be self-sufficient and more productive”

Isn’t self-service BI easy?

On the surface, yes.  It sounds easy:  Import some data, clean it up a bit, join some tables together, write a few simple calculation formulas and throw it into a chart… and viola!  A dashboard.  With some practice and a little training, some parts will be easy but the challenges of data integration, conformity, quality and master data management are ago-old problems that will always be present when data is sourced from different systems and is handled and manipulated by different people.  This is where the democracy of self-service BI and the rigidity of governed solutions can collide; and BI projects of any scale will get complicated… regardless of the tool.

The good news is that we’ve been doing this a long time and have developed disciplines and best practices to manage blended solutions.  With careful management and diligence, ad-hoc solutions can be made to scale and endure the transition.  In the article I wrote last year, titled “Business Intelligence Roles and Team Composition”, I discuss lesson learned about balancing business-owned BI with IT-managed BI and how team members assume roles to balance solution objectives.

Another very important consideration is that the objective for most self-service analysis projects to create “good enough” models and reports for a specific purpose.  When a project graduates to a different form, intended for more users to answer more questions or for leaders to make informed decisions; different rules of data quality and reliability apply.

Back to Power BI

One of the most significant reasons I’m optimistic about Power BI as a serious business tool is that it is comprised of technologies I’ve learned to use in serious business scenarios over the past several years.  Although the new user experience is simple, the product heritage is quite extensive.  Let’s do a quick review of the products and components that have led to the current Power BI service offering from Microsoft…

The lion’s share of the work on Power Pivot and Power View begin back around 2008 and the first versions of these tools were release in 2010.  This included the Power Pivot add-in for Excel 2010 followed by integration with SharePoint, along with Power View.  Power Query was released in public preview shortly afterward and then all these tools were integrated into the first official Power BI subscription for Office 365.

This is where things got complicated for enterprise customers… Many enterprise-scale organizations don’t upgrade Microsoft Office on an aggressive schedule so business users don’t have access to these wonderful self-service BI tools in the corporate licensed copies of their desktop software.  The transition from 32-bit to 64-bit Office has been a tough nut to crack as well.  Enter the Power BI Designer (soon to be called “Power BI Desktop”)…  With the new designer, there are no Office/Excel version compatibility problems but if Excel users want to continue to use Excel, they still have that option.

Enterprise-Class BI

There are several things to consider when scaling a solution but in brief, Power BI currently offers a few options for managing data centrally or migrating datasets to managed servers.

  • The Data Management Gateway enables data in a published model to be refreshed at regular scheduled intervals with on-premises or cloud-based data sources.
  • The Analysis Services Connector enables reporting & visualization from an on-prem instance of SSAS (currently Tabular only) without copying the data to the cloud.
  • The Power BI REST API gives us the ability programmatically push data into, and refresh, the model at will.

We work with some organizations who, for various reasons, can’t utilize cloud services for some of their reporting scenarios.  Most data professionals I talk to don’t know where this boundary lies for them and it’s an important discussion to have with strategic leaders and decision makers.  Many businesses are adopting cloud services for strategic use and I’m learning to approach this topic using appropriate language to discover where those opportunities are. For example; if I were to ask a business leader if it would be OK to move their precious data to a data center offsite and outside of their IT control, she will probably say “no”.  But, if I were to ask if we could consider using an encrypted cloud service from a trusted service provider that is likely more secure than your online banking site – at a fraction of the cost and in less time, she is likely to say “let’s investigate that option”.  Sometimes, it’s a matter of presentation.  A healthcare company may not be able to allow patient  personal information to be used in a cloud-hosted data model but may have no issues publishing facility data in a securely-managed solution.

The good news is that a lot of Power BI capabilities are available for on-prem solutions with cross-compatibility between Microsoft BI products.  The path to move between cloud-based Power BI and the confines of the corporate firewall isn’t entirely concrete and is a moving target on a few fronts, as the products continue to evolve.  The two points I think about in this regard are that: one, development of these tool is moving forward at a rapid pace, giving us new options all the time.  The second point is that we’ve had a lot of experience testing the water and learning what options are supported and actually work well.
