All Rights Reserved Process Strategy The objective is to create a process to produce offerings that meet customer requirements within cost and other managerial constraints Copyright © 2020, 2017, 2014 Pearson Education, Inc. All Rights Reserved Process Strategies (1 of 2) • How to produce a product or provide a service that – Meets or exceeds customer requirements – Meets cost and managerial goals • Has long-term effects on – Efficiency and production flexibility – Costs and quality Copyright © 2020, 2017, 2014 Pearson Education, Inc. All Rights Reserved Process, Volume, and Variety Figure 7.1 Copyright © 2020, 2017, 2014 Pearson Education, Inc. All Rights Reserved Process Strategies (2 of 2) Four basic strategies 1. Process focus 2. Repetitive focus 3. Product focus 4. Mass customization Within these basic strategies, there are many ways they may be implemented Copyright © 2020, 2017, 2014 Pearson Education, Inc. All Rights Reserved Process Focus (1 of 2) • Facilities are organized around specific activities or processes • General purpose equipment and skilled personnel • High degree of product flexibility • Typically high variable costs and low equipment utilization • Product flows may vary considerably, making planning and scheduling a challenge Copyright © 2020, 2017, 2014 Pearson Education, Inc. All Rights Reserved Process Focus (2 of 2) Figure 7.2(a) Copyright © 2020, 2017, 2014 Pearson Education, Inc. All Rights Reserved Repetitive Focus (1 of 2) • Facilities often organized as assembly lines • Characterized by modules with parts and assemblies made previously • Modules may be combined for many output options • Less flexibility than process-focused facilities but more efficient Copyright © 2020, 2017, 2014 Pearson Education, Inc. All Rights Reserved Repetitive Focus (2 of 2) Figure 7.2(b) Copyright © 2020, 2017, 2014 Pearson Education, Inc. All Rights Reserved Product Focus (1 of 2) • Facilities are organized by product • High volume but low variety of products • Long, continuous production runs enable efficient processes • Typically high fixed cost but low variable cost • Generally less skilled labor Copyright © 2020, 2017, 2014 Pearson Education, Inc.
