Lean Six Sigma Introduction

As the resident LSS black belt at a local community hospital, I have been requested to construct a Lean Six Sigma introductory presentation for all new employees. Upon completion of the hiring process, all new employees will perform an on-line orientation which will now include a very basic overview of Lean Six Sigma. It will be more basic than a White Belt level as the employee mix will range from food service and housekeeping, to clinical and managerial staff members. Thus I would like to know if anyone has developed a slide show presentation that can be useful for all hospital personnel to understand the basics of LSS.
