Economists identify gaps between the optimized allocation of resources and the current allocation level in a process called gap-analysis. Whereas Surgeons diagnose preoperative patients, perform the necessary operation and provide postoperative surgical care.
Both professions are using a similar framework method to manage and analyze qualitative and quantitative data.
Dr. Tilleman’s consulting firm’s framework, seminars, and books teach how to implement that proven process, yielding outstanding results.
