ABSTRACT
This paper discusses and illustrates the evaluation of health care systems from the perspective of statistical quality management. Many health care organizations have use of statistical quality management and basic statistical process control has to become wider. Statistics Process control has been commonly used in many areas of Engineering Finance and Health care statistics. Although there many ways to analyzing and improving in Healthcare Quality. But SPC is the best one to identify the result .I using a excel model to showing the result for healthcare system.

Introduction

Today healthcare is more and more important in our true life. People pick up the healthcare that’s because many people have no longer to face food shortages, worm house etc. More and more people forcing on Life quality.
