I've altered the title. I can see how it upset some people expecting it to contain some SQL magic.

This happens all the time. Anyone that says this doesn't happen in 2010, or that it's obvious you communicate with the business, or agile solves this, is full of crap. Good people with good communication skills and willing to try and work with others solve these issues. Too often in all phases of business, not just technology, we don't have those people.

I debated about how to phrase it and run it, and in the end like what Stephen had done. It's a well written reminder that there's more to our jobs than code.

I can't believe this even made it into sqlservercentral. If this dribble is the quality of articles to come I think I will look for a better provider.

If you can't interact with the whole business entity then you are in the wrong vocation and you should think about a change of career.


I think that replies should avoid attacking the author of an article. That is not productive at all. The author took the initiative to share an experience. If you believe the author to be in error, reply with respect and include the logic behind your opinion. If you don't feel this way about it, please refrain from replying.

It implies there is some meaningful, presumably technical information within.

I think you got the point while missing the point. Not all solutions to technical problems are technical. Stepping back and asking "What do we really need?" is an important and oft overlooked strategy to solving a problem.

An excellent article with emphasis on how to involve users in the design process. About 40 years ago I was working with a main frame system person as a representative of the business users of the company. He asked me what I wanted and how would I like it to look (in those days, users did not touch consoles).

He was the first computer person that ever asked me what I wanted. I never forgot him and as a developer for the last 33 years, I ask the same question of my users. I also want to learn how they work so that my system does not force them to alter their work flow.

The programming is just a tool to give the users what they want. Thanks for reminding us.

Dear Stephen,
How does this improve the query speed when the previous 3 hour sql and current 15 seconds sql actually querying diffrent tables and views?

Wondering why your team waited till UAT to find this very visible issue Hehe.

This is a forum, inviting users to express their opinion.

I would consider using cut & paste to repeat your comment along the thread contributes nothing of substance.

Perhaps my comments about the article was a little harsh, but I like many others were tricked into reading this article which meant that other articles submitted by other authors were robbed of some exposure to the readers (reducing their AIR).

In my experience developers have plenty of opportunity to interact with the whole business but they choose not to. They're not interested in contributing and assume that just coding page after page of shocking code makes them a developer.

In my humble opinion the title should be "get your head out of the sand and interact with your business and you'll find you can achieve so much more!".
