- i) The concept of quality is considered to have evolved through stages. However, quality is used to describe a prestigious product. It is one that fits the intended customer’s requirements. Impliedly, the product should possess attributes that enables it meet the customer’s requirement or specification. Now, in identifiably distinctive manner, differentiate quality control from the others or quality assurance. ii) Briefly define hazard, when uncertainty is defined as being a situation in which the determination of risk factors is not possible. It is difficult therefore to calculate the effect of uncertainty upon the tender, and a discussion of uncertainty is out of place here. A builder will see risks in two distinct categories: (a). those that can be insured against and,( b). those that cannot be insured against.arrow_forwardAbernathy, Inc., produces two different generators and is concerned about their quality.
