The evolution from character based user interfaces using MS-DOS to graphical user interface using MS Windows 95/NTand 32 bits architecture causes the complexity of the application to increase significant.
- By adopting new processes, methods and technology which gives the opportunity of component based reuse, we target quality improvement, increased productivity and decreased time to market.
- The goal is to reach level 2 and parts of level 3 of the Reuse Maturity Model (RMM).
The experiment will introduce organised reuse by using a component based object-oriented development process.
New roles, methods and techniques will be used to create a new software development process which will result in reusable components.
The experiment will include the following activities:
- New roles will be introduced to dedicate knowledge vertically. Roles will be defined that each covers a special interest responsibility; Client/Server architecture, Repository administration, User interface, OLE business logic and design
- Object oriented development will be done using OO-ram.
- A component repository will be constructed.
- The experiment will be processed in steps of 3 months length, with evaluation after each step.
- Metrics based upon GQM will be used to evaluate the process.
The experiment foundation are two baseline projects:
1. Baseline 1, which is maintenance of a invoice system developed in COBOL with no reuse.
2. Baseline 2, which is a new development of the invoice system developed in Borland Delphi with reuse as a main goal.
Baseline 1 will be used as scale for the metrics on baseline 2.
DI Systemer AS has a total of 20 employees, 7 of these will be involved in baseline 2.
EXPECTED IMPACT AND EXPERIENCE
DI Systemer AS has the goal to improve their development process by introducing organised reuse that satisfies level 2 and parts of level 3 of the RMM specification. DI Systemer AS will continuously expand and improve their component repository and expects in near future to achieve a reuse grade of over 40%.
