A company is in the final phases of implementing a project for a client.

The business analyst could use the expected vs. actual results technique to iteratively validate the solution. This technique involves comparing the expected results or outcomes of the solution with the actual results or outcomes that are observed or measured after the solution is implemented. This technique helps to verify that the solution meets the requirements and the acceptance criteria, and to identify any gaps, issues, or defects that need to be resolved or corrected. References: PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline1, page 25; Business Analysis for Practitioners: A Practice Guide2, page 141.
