Once your solution is up and running, you need to track and report the progress and results of your solution to your customer. You can use various tools and methods to collect and analyze data, such as dashboards, surveys, feedback forms, interviews, testimonials, case studies, and so on. You need to align your reporting with the success criteria and the KPIs that you agreed with your customer, and highlight the achievements and challenges of your solution. You also need to provide recommendations and suggestions for improvement and optimization, and show how you can add more value and solve more problems for your customer.
