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.
************************************

Which of the following provides the best example of a product risk leading to a project risk?

A.
The signalling systems may have more defects than anticipated, leading to the need for more
retesting to be carried out.

B.
There may be unexpected lags on the network traffic communication, causing drivers to slow
the trains down unnecessarily.

C.
The new development staff may require training for this type of system, which, if not carried out,
may lead to an increase in the number of defects introduced.

D.
The budget may need to be increased significantly during the project, otherwise there may be
delays in the delivery of the system.
