Improvement of Software Testing Phase, with Respect To Requirements Management & Change Control

 

Subject Index Code : Electronics, Microelectronics, Information Processing, Information Systems

Other Indexes : Software testing, test coverage, requirements management, change control, traceability

Objective : Israel Aircraft Industries (IAI) develops, manufactures and maintains embedded systems for the aerospace and large electronics systems market.

Software is an essential part of all IAI's advanced products. We are interested to enhance the efficiency and effectiveness of the software testing phase, a major quality factor and cost driver in complex mission critical systems, especially with respect to automation of requirements coverage and change control.
The objective of this experiment is to reduce the time and effort required for testing activities without reducing product quality, thus reducing the cost of development to improve our competitiveness and shortening time to market while improving customer satisfaction.

General Information : THE EXPERIMENT The aim of the proposed Process Improvement Experiment (PIE) is to improve the software testing phase at the component and at the integration level.
The experiment especially focuses on the relation between testing and requirements coverage which is central to achieving satisfaction of our customers needs. This experiment will refer to following aspects of the development process:

  • Software testing during various software testing phases to obtain satisfactory coverage within project time and budget constrains using the Logiscope tool (or similar) .
  • Management of system requirements allocated to software using RTM tool (or similar) .
  • Management of requirements changes using a data base application developed at IAI (RCR) .

This will be used to control requirements changes : description of desired change, cost estimation
of the change, impact and risk assessment of the change and recording of resolution.

The output of this change control process will drive the changes to the base line requirements data base in RTM.The baseline project is an advanced avionics system enhancement including hardware modifications as well as extensive software development of its main five components. The development effort is presently estimated at over 20 man years. This baseline project is typical for IAI and reflects the commercial market trend of our products which demands high quality, increasingly complex functionality and short development time.

EXPECTED IMPACT AND EXPERIENCE :

IAI expects to increase test coverage of requirements, increase the percentage of code exercised in testing and reduce integration testing cycle time. Consequently we expect to reduce software development costs while increasing product quality, especially in mission critical systems. In the PIE we want to demonstrate the following Measurable Objectives: Increase test coverage of requirements by 15%; Reduce integration testing cycle time by 5% Reduce software testing costs by 10%; d. Increase percentage of code exercised in testing by 15%.
