DOM 511 :Operations Management Practice1- Overview By: Munyao-mulwa UON School of Business Dept of Management Science
What is Operation Management? • Manufacturing: Getting the products a company makes to an agreed specification, in due time • Transport: Ensuring the transport runs to an agreed schedule • Retailing: Pushing the merchandise through the store to the consumer • Service: Providing satisfactory, according to an agreed schedule, the service to the customer Operations Manager: • The supplier of products or services required by the market place • Utilises the organization resources to meet the product or service specifications efficiently & effectively
Operations ManagementDefinition • Operations management may be defined as the design, operation, and improvementof the production system that creates the firm’s primary products and services. • Analysis of definition;- 4
Operations ManagementDefinition • OM is the science & art of ensuring that goods & services are created & delivered successfully to customers. • Applying the principles of OM entails a solid understanding of people, processes, & how they are integrated within a business to create value 4
From General Management To Operations Management • Traditional Management paradigm revolves around planning, organizing, directing & controlling • OM is the only means by which managers can directly affect the value provided to all stakeholders – customers, employees, investors & society 4
From General Management To Operations Management Key activities for OM discipline; • Understanding the needs of customers, measuring customer satisfaction & using the information to develop new & improved goods & services • Building quality into goods, services & processes & continually improving them to reduce errors, defects & waste • Using information about customers, goods/services, operations, suppliers, employees etc to make better decisions 4
From General Management To Operations Management Key activities for OM discipline; • Exploiting technology to design goods & services that respond rapidly & flexibly to customer requirements & improve productivity • Creating a high-performance workplace thro’ training, rewards etc • Continually learning from co-workers, competitors & customers & adapting the organization to global & environmental changes 4
OM Discipline OM principles are not complicated for they constitute the “basics” of everyday life eg Respect for customer experience Focus on the dynamics of demand Recognition that experience is delivered by people etc >>The fundamental purpose of OM is to deliver ever-improving value to customers through the continuous improvement of overall company performance & capabilities 4

Transformation Process Input Output (Value Adding) OM Involves Managing Transformations • People • Plants • Parts • Processes • Planning and Control Transformation is enabled by The 5 Ps of OM: 6
Operations ManagementDefinition • Value = quality / price • How can an organization increase customer value? 4
OM’s Transformation Role • To add value • Increase product value at each stage • Value added is the net increase between output product value and input material value • Provide an efficient transformation • Efficiency – perform activities well at lowest possible cost 7
Transformations • Physical--manufacturing • Locational--transportation • Exchange--retailing • Storage--warehousing • Physiological--health care • Informational--telecommunications 7
Systemic Approach Greater value than inputs Requirements • Inputs • Material • Machines • Labor • Management • Capital • Outputs • Goods • Services Transformation Process Feedback Feedback Push or Pull?

Trends in OM • Service sector growing to 50-80% • Global competitiveness • Demands for higher quality • Huge technology changes • Time based competition • Work force diversity
Why OM? • For long-run success companies must place much importance on their operations • The 1950-1960 era was the U.S. golden era where primary opportunities were marketing • The 1970-1980 U.S. companies experienced a large decline in productivity growth – international firms began to challenge in many markets • The 1970-1980 era saw U. S. firms lagging behind in methods and processes • The resurgence of American business in the 1990’s capitalized on improved operations
Today’s OM Environment • Customers demand better quality, greater speed, and lower costs • Companies implementing lean systems concepts – a total systems approach to efficient operations • Recognized need to better manage information using ERP and CRM systems • Increased cross-functional decision making
OM in Practice • OM is the most diverse organizational function • Manages the transformation process • OM has many faces and names such as; • Chief Operating Officer, V. P. operations, Director of supply chain, Manufacturing manager • Plant manger, Quality specialist, etc. • All business functions need information from OM in order to perform their tasks

Objectives of Productive Systems • Volume of output • Cost (materials, labor, delivery, scrap…) • Utilization (labor & equipment) • Quality & product reliability • On-time delivery • Investments (ROI) • Flexibility for product change • Flexibility for Volume change
The Lifecycle of a Productive System • Birth of the System • Product Design & Process Selection • Design of the System • Start-up of the System • The System in steady state • Termination of the System
Key Decisions in the life of a Productive system • Birth of the System • What are the goals of the firm? • What product or service will be offered? • Product Design & Process Selection • Design of the System • Start-up of the System • The System in steady state • Termination of the System
Key Decisions in the life of a Productive system • Birth of the System • Product Design & Process Selection • Form & Appearance of Product? • Technologically, how should the product be made? • Design of the System • Start-up of the System • The System in steady state • Termination of the System
Key Decisions in the life of a Productive system • Birth of the System • Product Design & Process Selection • Design of the System • Capacity? • Location? • Lay-out? • How to maintain quality? • How to determine forecast for demand? • What job is each worker to perform? • How will the job be performed & measured? • How will the workers be rewarded? • Start-up of the System • The System in steady state • Termination of the System
Key Decisions in the life of a Productive system • Birth of the System • Product Design & Process Selection • Design of the System • Start-up of the System • How do you get the system in operation? • How long will it take to reach desired level of output? • The System in steady state • Termination of the System

Key Decisions in the life of a Productive system • Birth of the System • Product Design & Process Selection • Design of the System • Start-up of the System • The System in steady state • Termination of the System • How does the system die? • What can be done to salvage resources?
Output Input Productivity = Productivity • Become more efficient • Downsize • Expand • Retrench • Achieve breakthroughs Productivity improves when firms:
Productivity • Partial measures • output/(single input) • Multi-factor measures • output/(multiple inputs) • Total measure • output/(total inputs) 17
Example 10,000 Units Produced Sold for $10/unit 500 labor hours Labor rate: $9/hr Cost of raw material: $5,000 Cost of purchased material: $25,000 What is the labor productivity? 18
Example--Labor Productivity 10,000 units/500hrs = 20 units/hour ... ... or we can arrive at a unitless figure (10,000 unit*$10/unit)/(500hrs*$9/hr) = 22.22 19
Competitiveness The degree to which a an organization can produce goods and services that meet the test of international markets while simultaneously maintaining or expanding the real wealth of its shareholders.
Competitiveness • Competition Intensity is high when • Firms equal in size • Resources, products & services standardized • Slow industry growth (battle for market shares, the global market remaining constant) • Industry growth exponential (you must have a foothold in the market) • Consequences • Price wars • Relentless advertising • High Frequency of introduction of new products & services • Free trials • Low profit margins • Purchasing incentives • Switching bonuses • Financial packages; cheap credit
Entry Barriers • Economies of Scale • Fixed & variable costs • Unit cost decreases when capacity increases • Newcomers: insufficient orders to justify large capacities => higher costs • Initial Capital Investment • May be prohibitive (service to community, hospital, robotized mega plant) • May be low: e-commerce, consulting… • Access to Supply & Distribution Channels • May be controlled by (major) Competitors Bargaining Power (Porter) • Exclusivity agreements • Largely easier when going to e-commerce (no broker, distributor needed) • Learning curves • Lack of experience, skills, expertise can be penalizing (aerospace, shipbuilding [10% cost reduction for each similar ship built])
