The scenario describes a project that aims at improving an organization’s Net Promoter Score (NPS), which is a measure of customer loyalty and satisfaction. The BA and stakeholders are looking for ways to measure the performance of the solution and its impact on the NPS. One of the techniques that may be employed for this purpose is focus groups, which involve gathering feedback from a representative sample of customers who have used the solution. Focus groups can help to evaluate the value, usability, and quality of the solution, as well as the customers’ likelihood to recommend it to others.
