Test Management

Question

Scenario 5 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 organisations. The management staff have 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. Which of the following provides the best example of a product risk leading to a project risk?

Options

  • AThe signalling systems may have more defects than anticipated, leading to the need for more
  • BThere may be unexpected lags on the network traffic communication, causing drivers to slow the
  • CThe new development staff may require training for this type of system, which, if not carried out,
  • DThe budget may need to be increased significantly during the project, otherwise there may be

Explanation

Option A correctly illustrates a product risk causing a project risk: the signalling system containing more defects than expected (a product quality concern) directly triggers the need for additional testing resources, time, or budget - all of which are project-level concerns. This is the defining pattern: a flaw in the product itself cascades into a threat to the project's delivery.

Option B describes a product/technical risk (network lag) leading to an operational or safety consequence (drivers slowing trains), not a project management impact - so the second half is not a project risk. Option C starts with a project risk (staff lack skills/training), not a product risk - the causality runs the wrong way. Option D also starts with a project risk (budget pressure) rather than originating from a product quality issue.

Memory tip: Think "bad product breaks the project." If the thing being built has a quality problem that then threatens schedule, budget, or resources - that's product → project risk. Any option that starts with people, money, or process is already in project-risk territory.
