3 1. Motivation Personal experience in workflow management Experienced lack of proper change request management for small IT projects à Model CRM through workflows for small software projects with strong customer focus Partner: Robert Bosch Singapore Product Manager Workflow Management WorkON 200,000 users, 300 applications Heuschild sebis 3

Basic Principles Change Request Management Resons for Change Requests Dependent for Requirements Engineernig Independent from Requirements Engineering Implementation Problems Costs / Budget Incorrect Requirements Scheduling Ambiguous Requirements Strategy (Marketing / Sales) Technical Changes Changes in Business Environment Changes in Laws / Governmental Regulations New Requirements concerning Security Heuschild sebis 5

15 5. Pratical Exmaple Change Requet Management for WorkON Six Gaps 1. Missing CR ranking 2. Missing information 3. Classification of changes 4. Project does not follow CR-process 5. Tool does not support every process step 6. Tool is not self-explaing / easy-to-use Heuschild sebis 15

18 5. Practical Example Change Request Management for WorkON New Project Schedule Heuschild sebis 18

19 6. Evaluation & Conclusion Benefits 1. Tool supports process 2. Easier decision-making 3. Ranking available 4. Improved reporting 5. Reduced processing time 6. Less user administration 7. Reduced costs Six Gaps 1. Missing CR ranking 2. Missing information 3. Classification of changes 4. Project does not follow CR-process 5. Tool does not support every process step 6. Tool is not self-explaing / easy-to-use 8. Better process documentation 9. Less familiarization time Heuschild sebis 19

Missing information 3. Classification of changes 4. Project does not follow CR-process 5.
