The risk impact is the measure of the potential negative consequences of a risk item on the project objectives. It depends on the severity of the defect, the frequency of occurrence, and the visibility to the stakeholders. Since requirement R1 is business critical, any failure in meeting this requirement would have a significant impact on the customer satisfaction, the reputation of the organization, and the legal compliance. Therefore, the risk impact for requirement R1 should be categorized as high or very high, regardless of the likelihood of occurrence. References =

Classification trees are a visual way of identifying test objects and data, and pairwise testing is a technique of generating test cases that cover all possible pairs of values from different classifications. Classification trees support pairwise testing by:

• Helping to identify inputs to be used by the pairwise test technique, as each class represents a possible value for a test parameter.
• Showing the combinations needed to cover all-pairs, as each test case is a selection of one class from each classification.
• Helping to identify particular combinations of interest, as the test engineer can use the tree structure to group or prioritize classes based on their relevance or risk. References = ISTQB Advanced Level Test Analyst Syllabus 2019, section 3.2.3; Smarter Test Design with Classification Trees and Pairwise Techniques, slides 6-12.

The minimum acceptable level of coverage for this use case is to cover all the scenarios and their combinations. Therefore, we need at least one test case for each of the following:

• Basic scenario single-sided to single-sided
• Alternative single-sided to double-sided
• Alternative copy of a set
• Alternative copy using the automatic document feeder
• Error no paper in paper tray
• Error paper jam
• Error out of staples References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 63, section 4.4.2.2.
