I am a senior Program - Project Manager (EPC) with 60+ years of experience on very large and complex projects. My experience shows that there is a misunderstanding in what a schedule is - and how to utilize one effectivelly. I want to quiz the scheduling community on what is wrong with scheduling and how to improve it. I will disclose I'm thinking of writing a book on Project Management on how to achieve success without a new achronym or completely upsetting the apple cart. Let me know your thoughts.
