CHAPTER ONE
1.1    GENERAL INTRODUCTION
    it is important at the outset of this discussion to know exactly what is quality control i.e. it is a degree of excellent, fitness and elative nature.

This is because they can bring about three important types of knowledge, their knowledge of the material, they bought their knowledge or market or economic change their knowledge of sources of supply.
    A concept of quality as outlined above could in turn be derived into a number of constraints, such as finish, strength design material, manufacture and so on and the scale of excellent could be draw up for this in such a way that we can analyses the quality of   given it may score well is some respect and badly in others, it may be in incapable of measurement. The researcher is interested in this topic because quality is very biologics business.
