Susan Scachitti is a Professor of Industrial Engineering Technology at Purdue University Calumet. Professor Scachitti consults and teaches in traditional areas of Industrial Engineering which include Total Quality techniques and organizational change, methods engineering (including Lean methods), facility layout, process improvement, simulation and ergonomics. Prior to working in education, she spent ten years in various engineering and supervisory roles in the telecommunications industry which focused on high volume electronics manufacturing. Her accomplishments include implementation of Total Quality principles including Lean Manufacturing concepts, Demand Flow Technology, self-directed work teams and various other techniques that improve overall process efficiencies within the organization. Also, she held key roles in successfully attaining ISO9001 certification, establishing a benchmark for a self-directed workforce, conducting economic analysis and cost justifications for new manufacturing technologies as well as utilizing various other industrial engineering concepts to reduce cycle times and increase production efficiencies. Since 2004, Professor Scachitti has focused her efforts towards applying Industrial Engineering concepts to improve Healthcare and other non-traditional service environments using Lean and Six Sigma methods.

Application of Lean Six Sigma in Healthcare – A Graduate Level Directed Project Experience Continuous change in complex healthcare environments is a challenge for nurseleaders, but it can also be an advantage. Change can leverage the introduction ofinnovations that improve the quality of care delivery. It all depends on how change ismanaged. Six Sigma and Lean are two powerful performance improvementmethodologies that are changing the face of modern healthcare delivery. From theemergency room to the board room, Lean Six Sigma (LSS) can reduce variability andtherefore waste - fewer errors, better processes, improved patient care, greater patientsatisfaction rates and more productive employees that translate to bottom-lineimprovement. LSS is a combination of Lean methods and Six Sigma approaches and itbuilds on the knowledge, methods and tools derived from decades of operationalimprovement research and implementation. In this project the workload of Nursing ShiftDirectors’ (NSD) has been analyzed. NSD are responsible for the administrative directionof the healthcare facility including serving as a clinical resource person, interpreting andenforcing policies and procedures, intervening in difficult situations and medical crises,having overall responsibility for appropriate utilization of nursing personnel and forpatient placement, and serving as a liaison to facilitate communication and problemsolving within the healthcare facility. The purpose of this study is to (a) create a baselinemetric of the existing process, (b) collect operational data and analyze ways to improvethe work efficiency by eliminating the non-value added tasks from the daily workload, (c)automate some of the tasks performed by NSD and (d) monitor and provide controlmethodologies for sustainability.
