SOFTWARE PROCESS IMPROVEMENT FOR AVIONICS SYSTEMS

Objective

Embedded systems become more and more complex. The software part of embedded systems is increasing in costs, complexity and risk. A key solution for solving this problem is to act on the process management itself. This application experiment, by the use of new modelling method and best practice such as process management techniques was conducted to improve quality and productivity into the System and software engineering process applied to embedded systems.

THE EXPERIMENT

IMPROVE focuses on software development process modelling with PROCESS WEAVER tool. This experimentation took place in a real user environment to evaluate the competitive advantages in term of time to market, concurrent design and improvement on predictability and repeatability for software development process. The achievement of the objective above requires the improvement of process management practices and the implementation of methods and tools as follows:

1) Process Design,
2) Integration of the workflow in the system and software workshop,
3) Process Implementation with the workflow,
4) Electronic Process management

The experiment has been performed in the same company, but between two different organisations geographically separate (two different servers with their own clients and their own corresponding processes to the responsibility).

EXPECTED IMPACT AND EXPERIENCE

The expected result was:

- improving co-operative working within software process,
- simplifying the certification process by giving more confidence on management and reliability of the development software process,
- raising the software engineering process maturity,
- increasing productivity in software development

The experiment shows the real improvement using formalised Process Design Methodology (A,B,C). Due to the restriction on a demonstrative real case and the duration (only 12 months), only some of the workflow characteristics have been verified, but without the ability to quantify the time cycle gain (D). The workflow used seems to be very adaptable to heterogeneous network environment. The deployment of the Design Process Methodology is in progress. The use of workflow tools is under studies for new programmes at an enterprise level.
