Where’s My Magic Quadrant?

When I got involved with Kalido over 15 years ago, we had big plans to change the world of data warehousing, and we still do.  However, one frustration we’ve had over the years is recognition from the major analyst firms that how we build data warehouses is fundamentally different and merits a “Quadrant” or “Wave” of our own.  In a nutshell, we think that the old way of building models with ER modeling tools, having DBAs create physical tables from those models, and then hardcoding the population of those tables with an ETL tool can never allow a business to be as agile as they need to be.

Estimating Velocity

Velocity is perhaps the most important concept in agile development. In his recent Agile 101 class at the TDWI BI Summit in San Diego, Ralph Hughes defined velocity as “The number of story points that can be delivered comfortably in an iteration.” That estimate effects many other estimates, such as the size and mix of your teams, as well as the number of iterations needed to deliver the full project scope—all of which impact the budget.

Kalido and Anchor Modeling (AM)

Someone asked me my opinion of Anchor Modeling, and I had to admit that I hadn’t really looked at it in detail.  I’m not sure why — at first glance, “Almost 6th Normal Form” modified using a practical approach and software automation should be right in wheelhouse of people who work at Kalido!

Is Your Agile Warehouse Project Stuck in Second Gear?

The first twenty-plus years of data warehouse projects yielded failure rates above fifty percent, and the waterfall methodology took much of the blame. Ironically, as Ralph Hughes points out in his book Agile Data Warehousing Project Management, the waterfall methodology itself was based on a “grievous misreading” of another work. Dr. Royce’s 1970 white paper Managing the Development of Large Software Systems had called for a more iterative approach to systems development than the circa-1985 waterfall methodology it inspired.

But the wise man don’t know how it feels…

Who am I to let a good theme die?  Kudos to Jim Harris for his excellent follow up on his “Brickyard Chaos” blog with an even more insightful “Another Brick in the Wall” blog ( I love the Pink Floyd reference).  Truth be told, I’m a bigger classic rock fan than I am a NASCAR fan, thus the association of this blog to the epic “Thick as a Brick” from one of my personal favorites Jethro Tull.  Read more

Yeah, But Who Won The Race?

I just finished reading a Jim Harris blog “Chaos in the Big Data Brickyard”.  When I saw the title, I thought that it must be a reference to the Indianapolis Motor Speedway, a.k.a.”The Brickyard”.  I felt this was a reasonable assumption given the fact that NASCAR just ran their annual race there this past weekend.  Read more

A Good Data Warehouse Starts with a Firm Foundation

This seems so obvious that it hardly warrants mentioning, right? So why have I visited so many companies over my career where data marts, or even entire warehouses, were built using reference data from multiple sources where the data integration is ad-hoc and hardwired? Read more

Iterative (and Incremental) Warehouse Development

We have often discussed the concept of using an iterative methodology when constructing a data warehouse, and have detailed the benefits of such an approach: better alignment with business needs, faster delivery of results, better return on the investment and overall lower development costs, just to name a few. However, it is also important to understand how iterative methodology can support the not only the initial delivery, but also the ongoing extension and enhancement of the warehouse. I like to call this an “Incremental Methodology.” Read more

Kalido listed in “DBTA 100: The Companies That Matter Most in Data”

This week Database Trends and Applications (DBTA) magazine, recognized Kalido for “presence, execution, vision, and innovation in delivering products and services to the marketplace”. Our company is one of a notable list of data solutions providers included in the inaugural “DBTA 100: The Companies That Matter Most in Data.” Read more

Agility’s Growing Pains

I just finished reading a blog by Michael Fitzgerald, CIO Tough Love: Agility Demands Increasing.  In his recap of the 10th annual MIT Sloan CIO Symposium, Michael rightfully warns IT Executives to “brace yourself for pain as you push for agility”.  I couldn’t agree more.  And, the pain comes from many directions and takes on many forms, but there are proven tools and techniques to help you along the way.
