Topic 19, Scenario 11 "Incident Management"
The following is the current incident handling process in used at the company.
Step 1: Incident is documented in the incident Tile with the following information:
-Software module or area where the fault occurred
-Who has reported the fault
-Hardware configuration used for the test that found the fault
-The sequential incident number (1 greater than the last one recorded)
Step 2: Developer assigned to fix the fault Step 3: Developer fixes the fault Step 4: Developer signs off the incident as closed, and it is then removed from the incident file

In this scenario, the contract tester who has never worked for the organization before has the highest level of test independence. The three others are less independent as they are likely to make assumptions based on their previous knowledge of the requirements, code and general functionality of the original system.
Note that independence does not necessarily equate to most useful. In practice most test or project managers would recruit a permanent tester who has worked on the original system in preference to a contract tester with no knowledge of the system. However, when assembling a team it would be useful to have staff with varying levels of test independence and system knowledge.
