Through a rule, darkly
My observation is that business customers need to take ownership of, and be heavily engaged with, any process to try and improve this situation. It cannot be an IT-driven project. It is not critical whether the ultimate repository of this is a data warehouse, a master data repository or some different business rules repository entirely, but it is key that the exercise actually happens. At present the opaquenes and lack of consistency of business rules is not something that most companies care to own up to, yet it is a major controls issue as well as a source of a great deal of rework and difficulty in presenting accurate data in many contexts.
I was amused by the readership poll quoted that said that 61% of respondents say that they have "no standard process or practice" for business rules management. This might imply that 39% actually did, a number I would treat with considerable caution. Personally I
have yet to encounter any that does so on a global basis.
