With increased focus in the Bureau of the Census on applying project management and Capability Maturity Model Integrated techniques, quality management and measurement become ever more important. Production tasks such as data keying and response coding are suited to acceptance sampling quality control plans, where, given three parameters (lot size, sample size, and an acceptance number), one can project an average outgoing quality limit, interpreted as an approximate outgoing error limit. Typically, all lots are created with a set of parameters chosen to produce a specified error limit. This paper reports quality control operations designed for enhancement in two ways: to assure a particular outgoing error limit when lot size and sample size vary and to optimize efficiency, minimizing inspection workloads using estimates of incoming process error.
