Bill Inmon has given me this wonderful opportunity to blog on his behalf. I like to cover everything from DW2.0 to integration to data modeling, including ETL/ELT, SOA, Master Data Management, Unstructured Data, DW and BI. Currently I am working on ways to create dynamic data warehouses, push-button architectures, and automated generation of common data models. You can find me at Denver University where I participate on an academic advisory board for Masters Students in I.T. I can't wait to hear from you in the comments of my blog entries. Thank-you, and all the best; Dan Linstedt http://www.COBICC.com, danL@danLinstedt.com

Any time we get back to secrets, we seem to fall right back to the category of standards, standardization, measurement and enablement. The old saying is: "if you can't measure it, you can't monitor it, and if you can't monitor it - you don't know when it's broke, or you can't optimize it/fix it." Something like this anyhow.

The common feedback from the general project implementation community is usually: "Why do I need to standardize? Why should I document? Won't it take more time to follow standards than to build rapidly?"

Well, yes and no. If you don't standardize (or your team doesn't standardize), then your project usually cannot be repeated successfully. If the team doesn't standardize then looking back at "what you did right/wrong" is good and can be done, but doesn't provide any sort of "metrics enablement or measurement" abilities against what was done, versus what was estimated, versus what "should" have been done.

Furthermore, documenting the process usually doesn't occur - and when it does happen it's retro-fitted to the existing project just released to production. This also can cause a herculean effort to "reverse engineer" and understand what was built just to build up the documentation.

One more side-effect to these efforts (JAD/RAD typically) include a hit on: flexibility, scalability, and maintainability. In other words, without standards - the project better be a "one-off" never to be repeated in the near future. Reusability is extremely tough in an environment where standards have been tossed into the wind. IT ends up (usually) loosing their agility.

Ok - enough of this, this is all project based stuff. We learned all this in PMP/PMI, Six Sigma, TQM, and so on... what about the templates, how are they useful, can a project be successful using them, how can a project proceed without the "standards" being seen as a hindrance?

Well, there's always a slight hindrance for issuing and following defined procedures. There's always a hindrance to defining standard processes and procedures that are acceptable to the team and the organization. You just can't get away from that. So in this entry we will explore enabling tools and libraries of templates that will help you on your way.

ITIL: on the web at: http://www.itlibrary.org/
Has a plethora of templates, best practices, and standards for projects (including EDW projects). You need to order the books for these.

http://www.isaca.org/
Also has a large array of standards, templates, implementation paradigms and guidance based on SEI/CMMI Level 5.

Or of course you could seek out the Data Vault methodology and approach which has distilled down the templates specific to enterprise data warehousing, enterprise data integration. These templates have also been optimized for quick and easy to use build-outs of your projects. The Data Vault approach (when followed appropriately) helps you instantiate your goals to follow lean-initiatives, business process management, and cycle time reduction.

A few of the different templates that you should have in your project folder include the following:
* Statement of Work
* Service Level Agreement (templated, so you can fit the topic in appropriately)
* Roles and Responsibilities sheet (numbered in accordance with the project plan)
* Organizational Breakdown sheet (numbered in accordance with the project plan)
* Data Breakdown Structure (numbered in accordance with the project plan)
* Project plan (numbered - you guessed it - technically - 1.1.1, 1.2.1, etc...)
* Process Breakdown Structure (numbered in accordance with the project plan)
* Risk Estimation, Mitigation, and responsibilities sheets
* AS-IS and TO-BE data flow documents, and process flow documents
* AS-IS and TO-BE system architecture documents
* Project release plan
* Bug tracking/Enhancement tracking plan

and so on. There are a number of other documents required to make a project successful including the Statement of Work, possibly a letter of intent, Goals and Objectives, Phased approach definitions, Definition of "Success" criteria for development - test and production releases. Estimated person-hours, level of experience on the team (according to the Roles and Responsibilities), and training plan.

A good set of templates, coupled with a solid project approach can be utilized on any project from 800 person-hours to 50,000 person-hours. It can be used repeatably, it can be measured as to it's effectiveness, and when a specific "template" is left out, the RISK of removing that process from the project plan can be accurately assessed.

To be successful in one's endeavors one of the final ingredients is: the ability and desire to teach the client to fish, rather than implement what you have and walk out with your own methodology.... But then again, no one does that to you do they? :)

On the next secrets, we'll get in to what one of these numbering systems looks like and why it helps solve the pain in business today. We'll also address some of the issues plaguing IT, and keeping them from being "agile" in the business environment.

As always, comments are welcome.

Hope this helps,
Dan Linstedt
