Method of operation
Testing is a measure for obtaining insight into the quality and related product risks of a system or package when it is
put into production by an organisation. Since time and resources are usually limited, it is important to determine the
system parts or features that will require extra or less test effort early in the process. Practical choices must be
made here. Performing a product risk analysis (PRA) will help determine the areas of focus for the test.
A PRA within the framework of a test level is optional: if the master test plan PRA has already been done in sufficient
detail (i.e. at the level of characteristics and object parts), this step can be skipped. If there is no master test
plan PRA, it must first be determined what the test goals are and what relationship they have with the
characteristics/object parts that are to be tested in the relevant test level. This is done in a similar way to the PRA
for the master test plan. If there is a master test plan PRA, but not at the level of object parts, then the PRA should
be further refined.
The execution of a product risk analysis is divided into the following steps:
-
Determining the participants
-
Determining the PRA approach
-
Preparing sessions/interviews
-
Collecting and analysing product risks
-
Checking for completeness
These steps are explained in details under Product Risk Analysis.
Products
-
The risk tables with test goals and possible object parts per characteristic with risk indications, managed
separately and optionally established in the test plan
-
The PRA overview of characteristics/object parts with risk class, established in the test plan.
