IQ Principles in Software Development
This paper shows how we developed a 7-Steps-Method to determine, measure and improve DQ in our team. Based on an actual business process description, we worked out the critical process points. Then we interviewed all Team Members to get a basic idea of how our Information Customers rate Data Quality at all and within the sub-processes looking at the critical points. After we collect all that data we could set up a system that allows us to measure DQ in a Customers focus. This System is the basis for all our further work. Currently we are somewhere between Step 4 and 5, this paper will show consolidated and anonymous data till Step 3. We plan to continue publishing our results when further steps are taken 1 Problem Description We are an internal consulting group of 80 team members. Our organizational structure looks like a matrix. Beside our boss we have a sales-team, a production-team, a service and IT-team and 5 different customer focus consulting groups. All tools they used to organize their work were developed internally by their own. There are two main databases, which are used to manage the team, one focuses on projects the other is focusing on the skills of our staff. Both databases are maintained basically looking more on data collection than on DQ. Most of the users are concerned about systems accessibility, reliability of data, usability, understand ability and so on. On the other hand the users do not update the current software system timely, which is the most important for reports 438 To avoid very high complexity we based our metrics on the 16 dimensions Richard Y. Wang published. We also determine the user groups of our organization and the basic business processes. The service group contains: Secretary, Accounting, Quality Management, DQ-Management, and IT-Management. In our team philosophy IT and Services is not a department. We look at it as independent services providers addressing all department members. Each service unit is lead by a Service-Unit-Manager who assists, consults and coaches also the Head of Department. 3 Measure Customer Focus To answer all questions of our clients we set up a framework and designed a calculation model following our 7-Steps-Method.
