Production management involves planning and regulating operations to transform materials into finished products. The 5 Ps of production management are products, plant, process, programs, and people. The objectives of production management are to produce the right quality and quantity of products within a predetermined time and cost. Production management activities occur at both the strategic level (e.g. planning) and operational level (e.g. production control). Different types of production include batch, jobbing, project, mass/flow, and process production. Productivity measures the output to input ratio and can be improved through techniques like technology, employee training, efficient materials and processes, product design, and management methods.
