Process Improvement for RE - A Good Practice Guide
PI-GPG
|
|
Introduction
The PI-GPG supports the systematic and continuous improvement of a Requirements
Engineering (RE) process for critical systems. The module aims to create a
repeatable and well defined RE-process which fulfils both the technical
requirements of the critical system to be produced and the company specific
business and marketing needs.
Summary Description
The module contains a strategy for the controlled and economic introduction and
improvement of a RE-process. Essential properties of this improvement strategy
are:
- Goal oriented improvement to a quality oriented development process which
considers company specific business and marketing targets.
- Consideration of data and experiences of past projects for the
improvement.
- Integration of improvement strategy from existing process improvement
approaches such as SEI, Bootstrap, SPICE and ISO-9000.
The PI-GPG module contains a set of best practices for the application of the
improvement strategy. These practices include:
- Assessment and evaluation of an existing RE-process.
- Systematic definition of improvement goals for an RE-process including
business and marketing goals.
- Planning and carrying out of RE-improvement activities.
- Planning and management of the RE-improvement process.
- Control and information of the cost and adequacy of the RE-process
improvement.
Benefits and Application Areas
There is an increasing awareness of the importance of adequate RE-processes for
the development of critical systems. An adequate RE-process makes it possible to
avoid costly errors in later development phases and guarantees that the system
fulfils the customers needs.
The application areas are: production of complex software systems with high
requirements to reliability, availability, maintainability, security or safety.
Business sectors include: complex commercial application software, banking,
insurance, telecommunication, transport, aerospace and chemical industry.
How to Apply
The PI-GPG guide can be applied both for the introduction of a new RE-process
(this is valid for development processes where no or only poor requirements
engineering is performed) and for the improvement and adaptation of an already
existing RE-process.
The PI-GPG uses the other REAIMS modules RE-GPG, MERE, PERE, FRERE and PREview in
the context of continuous process improvement for RE. Nevertheless process
improvement for RE can be started by using the PI-GPG stand alone. The PI-GPG can
be used stand alone to start process improvement for RE or together with other
existing process standards like SEI, Bootstrap, SPICE, ISO9000 or ami.
