Process Stability and Process Capability in Public Schools

Summary: The purpose of the case study was to determine what a process capability study could contribute to the continuous improvement of learning processes in a public school (Riverview Learning Center). Rational subgroups of data contained 18 individual measures on 50 students per day for 65 days for a total sample size of 58,500 individual student measures. The process capability study method was an initial step toward applying process control to learning in public schools. The process improvements, following the case study, which were made in the public school included: a customer-driven system with extensive consultation with school principals; follow-up after instruction to evaluate the special processes in a regular classroom; following a Plan, Do, Check, Act cycle; replacing p/np charts with X-bar charts; collection of conformity data and using Pareto analyses; investigating the use of a light pen and laser system for collecting data on students' performance; investigating solutions to the special causes problem of students' absences; and using control charts with students to help them control their own learning behavior. The conclusions and recommendations are made for a customer-driven quality system, special processes, measured student on-task behavior, and the Plan, Do, Check, Act cycle in public school education.
