ABSTRACT
Reliability ranks with quality and efficiency in importance since it is a key factor in many purchasing decisions where alternatives are being considered. The prerequisite of lean quality is the continual examination of all the requirements and people ability to meet them, both in terms of product quality and reliability, and process reliability and efficiency. The formworker, who is paid by the square metre, is busy laying as much flat slab sheeting as possible so that his payment is maximized. The measurement of capability is extremely important if quality chains are to be formed within or outside of an organization. The quality of conformance to design is the extent to which the product or service achieves the quality intended in the design. The quality of finishes in many areas of construction are hard to judge, standards are loosely defined and assessments of quality are subjective.
