Top three EVM performance measures

Your project sponsor is not familiar with earned value management (EVM). You have been asked to provide him with a quick overview of EVM. Using the information covered in the readings, suggest the top three EVM performance measures (some may be indexes as well) on which you would educate your project sponsor. Explain what each measure tells the project manager. Also, identify other performance factors beyond EVM that you would communicate to your sponsor. Provide a rationale for your selection of topics.
