Re: business rules?

Why can't I have all 3? What are the
technical obstacles that prohibit "business
rules" from having all 3? (maintenance,
performance and flexibility)

I think we're talking past each other. I don't think the choice between maintenance, performance, and flexibility is the same as the choice between speed, quality, and expense.

Here is the choice between speed, quality, and expense:

1. Time is required to do a job well. The higher the quality the deliverable of a job, the more time it will take to complete that job.
2. Labor costs money. The more people work on a job, the greater the expense of labor to complete that job.
3. If you want a high quality deliverable, and you want to save labor costs, you can have a minimum number of people work on the task. But then the task will take more time because fewer people are working to complete it and live up to quality standards.
4. If you want a high quality deliverable, and you want it done quickly, you can have several people work on it to complete it quickly. But then you have to pay labor costs for several people.
5. If you don't really care about the quality of the deliverable, you can assign a minimum number of people to work on the job and force them to complete on a short deadline. But the quality of the deliverable usually suffers (design limitations and bugs).

Armchair philosophy is so much easier than software development! :-)

You've left out price. You can have maintenance performance and flexibility, that would fall under good an fast, but it is going to cost you.

2 out of 3 is about the best you can do.

Price.  Service.  Quality.
Pick any 2 . . .

The choice would be Low Price, Fast Service, and High Quality: pick any 2.
