The term that is assigned to this measurement is key performance indicators. These are the metrics that are used to evaluate the performance and progress of the organization, the project, or the solution against the predefined goals and objectives12. Key performance indicators help to monitor and communicate the value and benefits of the solution, and to identify areas for improvement. Henry and Fred are using key performance indicators to compare the productivity before and after the implementation of the new software, and to see the real effect of the solution on the business need. The other options are not terms that are assigned to this measurement, but rather concepts or techniques that are related to the business analysis work, such as post implementation factor (A), which is a factor that affects the success of the solution after it has been deployed3, yield (B), which is a measure of the efficiency or effectiveness of a process or a solution4, or S-Curve (D), which is a graphical representation of the cumulative progress or performance of a project or a solution over time5.
