The present case study presents a methodology general enough to be used in various fields of applications, as it was tested in different facilities, and service and production environments. Hospital was divided in departments and activities which cover emergency clinic and reception, outpatient clinics, inpatient treatment, operating theater, sterilization, laboratories, diagnosis, maintenance and engineering, biomedical engineering, nursing, financials, administration, pharmacy, and medical supplies. The hospital has 14 outpatient working clinics and more than 300 inpatient beds, just to give an idea about the size of activities involved. All the departments surveyed used a paper-based system evolved by each department personnel either created from their needs or brought from their previous work.
