Explanation
According to the PMBOK Guide, project monitoring and controlling involves the processes of tracking, reviewing, and regulating the progress and performance of the project. One of the tools and techniques for monitoring and controlling project work is data analysis, which includes methods such as performance reviews, trend analysis, and variance analysis. The project lead should use data analysis to collect and evaluate the operational usage data of the software system, which reflects the actual behavior andpreferences of the users. This will help the project lead to measure the delivered value of the project and identify any gaps or improvement opportunities. Building the functionality in the software to collect the operational usage data is the most accurate and reliable evaluation practice, as it avoids the biases or errors that might arise from other methods such as questionnaires, feedback forms, or interviews.
