Root cause analysis is a technique that involves identifying and analyzing the underlying causes of a problem or an issue. Root cause analysis can help the business analyst to determine how the selection criteria requirement was missed, and to prevent similar errors from occurring in the future. Root cause analysis can be done using various tools, such as fishbone diagram and the Five Whys. A fishbone diagram is a graphical tool that organizes the possible causes of a problem into categories, such as people, process, technology, environment, etc. A fishbone diagram can help the business analyst to visualize the relationships between the causes and the effects, and to identify the most likely root causes. The Five Whys is a questioning technique that involves asking “why” repeatedly until the root cause of a problem is revealed. The Five Whys can help the business analyst to drill down into the details of the problem, and to uncover the underlying factors and assumptions that led to the missed requirement. References: PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline1, page 21; Business Analysis for Practitioners: A Practice Guide2, page 101.

 A use case is a technique that describes how an actor interacts with a system to achieve a goal or perform a task. A use case consists of a main scenario and possible alternative scenarios that capture the normal, exceptional, and error flows of events. A use case can be used as a source for building tests of end-to-end business processes across business functions and systems, as it provides a comprehensive and realistic view of the expected behavior and outcomes of the solution. A use case can also help to verify and validate the functional requirements and acceptance criteria of the solution. References: PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline1, page 20; Business Analysis for Practitioners: A Practice Guide2, page 99.

Time-boxing is a prioritization technique that involves allocating a fixed amount of time or resources to each requirement or backlog item. Time-boxing can help the business analyst to review the amount of work the team is capable of delivering based on the approved project schedule by setting deadlines and constraints for each requirement or backlog item. Time-boxing can also help to focus on the most valuable and feasible requirements or backlog items and avoid scope creep or gold plating. References: = PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline (2019), page 11; Business Analysis for Practitioners: A Practice Guide (2015), page 66.
