Topic 5, Case Study# 5 Scenario
A rail services provider is upgrading its signalling systems, to allow train drivers and signallers to
communicate securely and timely.
This is seen as a safety critical system. The IT processes in place include many quality check
points, including the use of the V-model for software development.
The provider has recently lost many of its software development and test staff to other
organizations. The management staff has been retained, including the project and development
manager for this upgrade. A recruitment drive is underway.
You have been brought in as a new test manager, and you have been asked to review the
processes surrounding development and testing.
The project manager has been asked about a formal process of building test procedures using
specification-based techniques.

C.
Inspections of code should be carried out by the developers, whilst code walkthroughs should
include just the testers.
