The Problem With Defining Information Requirements

by Tim Bryce - 29 April 2009

Business AnalystAs many of you know, I have been active in the Information Technology (IT) industry for a long time now. It’s a strange business and, frankly, sometimes I wish I had never gotten involved with it. There are a lot of problems associated with IT, such as computer performance, capacity planning, security, networking, disaster recovery, but probably the biggest problem is requirements definition. In other words, accurately defining the information needs of the end-user. The industry is actually quite good at designing and writing software, developing data bases, and acquiring hardware, but after all these years they still have trouble understanding what the user needs to run his or her part of the business.

There is one camp that believes development to be an art form requiring free-spirited creative types of people, and another camp believing it to be a science requiring people that are more disciplined and organized.

The difference between an art and a science is subtle but significant. An art form is based on the intuitiveness of the person performing the work, something that is difficult, if not impossible, to pass on to another human being. For example, apprentices serving under an artist may try for years to emulate the master, but may never attain his level of skill and creativity. In contrast, a science is based on a governing body of concepts and principles and, as such, can be easily taught to others. From this perspective, programming can certainly be viewed as a science as it has certainly been taught and passed on to others for many years; further, it involves certain governing principles in terms of language syntax, approaches to defining program logic and construction. Some might argue the physical design of a report or screen requires creativity, and there is a certain element of truth to this as some look better than others. But even the design of reports and screens can be governed by certain principles in terms of layout, navigation, color schemes, etc.
