This document contains 5 questions for an Operations and Technology Management exam. The questions cover a range of operations management topics including competing on quality, cost, flexibility, speed and innovation using examples from manufacturing and service firms. Other topics addressed include the four basic types of production processes, Quality Function Deployment (QFD), precedence diagrams, aggregate planning strategies, six sigma quality concepts, Just-in-Time (JIT) systems, Poka-Yoke, Overall Equipment Effectiveness (OEE), and pull systems. Students are asked to discuss, analyze, solve problems and provide examples for each question.
