Dr Felton Lean 3 Basic Functions of Business Organizations : 3 Basic Functions of Business Organizations Ensure and allocating financial resources Produce goods or services Assess consumer needs, and sell / promote goods or services Dr Felton Lean Operations: A Transformation Process : Operations: A Transformation Process Workers Managers Equipment Facility Materials Land Energy Information Goods Services Operations and processes Feedback Performance Lead time The time between ordering a good or service and receiving it. Dr Felton Lean Operations Management : Operations Management The management of systems or processes that create goods and/or provide services. Planning Coordinating Executing Dr Felton Lean Slide 6: OVERVIEW OF OPERATIONS MANAGEMENT MODEL Transformation Process Output Goods or Services Control Input: resources raw materials machines personnel capital land/buildings utilities information etc. Dr Felton Lean Slide 7: Operations management is the process of obtaining and utilizing resources to produce useful goods and services so as to meet the goals of the organization. Dr Felton Lean Slide 8: • The difference between the cost of inputs and the value or price of outputs. Inputs Material Labor Capital Transformation/ Conversion process Outputs Goods Services Control Feedback Feedback Feedback Value added Value added Value of the output or price of the output as accepted by the customers, not just enforced by the supplier. Land Dr Felton Lean Slide 9: Operations management considers how the input are transformed into goods or services. Control is when something is learned about the goods or services that is used to more effectively transform future goods or services. Dr Felton Lean Slide 10: • The difference between the cost of inputs and the value or price of outputs. Inputs Material Labor Capital Transformation/ Conversion process Outputs Goods Services Control Feedback Feedback Feedback Value added Value added Value of the output or price of the output as accepted by the customers, not just enforced by the supplier. Land Dr Felton Lean Slide 11: Feedback and Control Measurements taken at various points in the transformation process for control purposes are called feedback. The process of comparing outputs to previously established standards to determine if corrective action is needed is called controlling Physical Flow Information Flow Dr Felton Lean Operations = Transformation Process : Operations = Transformation Process Inputs 5 Ms Management, Methods, Material, Machines, Maintenance Also: Personnel , information & energy Transformation/conversion process Cutting, machining, storing, transporting, investing, analyzing Output Goods/services Value-added The difference between the cost of inputs and the value or price of outputs.

Dr Felton Lean Slide 17: • Degree of standardization • Type of Operation • Manufacturing or Service Major characteristics of operational systems Dr Felton Lean Manufacturing or Service? : Manufacturing or Service? Production of goods Delivery of services “perceptible by the senses especially the sense of touch” WordNet ® 2.0, © 2003 Princeton University Dr Felton Lean Slide 19: Degree of standardization Dr Felton Lean Slide 20: Types of operations Dr Felton Lean Slide 21: Production management is concerned with the manufacturing of goods: Examples of goods: cars books chairs computers houses etc. Dr Felton Lean Slide 22: Manufacturing vs. Service Characteristic Manufacturing Service Output Uniformity of output Uniformity of input Labor content Measurement of productivity Customer contact Opportunity to correct quality problems before delivery Evaluation Patentable Table 1.3 Tangible High High Low Easy Low High Easy Usually Intangible Low Low High Difficult High Low Difficult Not Usually Dr Felton Lean Slide 23: Operations management is also concerned with the management of service industries as well as the manufacturing of goods. Dr Felton Lean Slide 24: What does Operations Manger Do? Dr Felton Lean Slide 25: Operations Management includes: Forecasting Capacity planning Scheduling Managing inventories Assuring quality Motivating employees Deciding where to locate facilities And more . . . Scope of Operations Management Dr Felton Lean Example: Airline Company : Example: Airline Company Forecasting: Weather, landing conditions, seat demands for flights. Capacity Planning: How many number of planes in each route? Scheduling: Scheduling of planes for flights and for routine maintenance, scheduling of pilots and flights attendants. Quality: Quality of the services, Safety. Dr Felton Lean Example: Automobile Factory : Example: Automobile Factory Forecasting: Demands for cars. Capacity Planning : Number of shifts, level of workforce. Inventory: Various component, parts. Scheduling: Scheduling of various types of cars, Scheduling of workforce. Quality: Quality of products, services. Dr Felton Lean Slide 28: Responsibilities of Operations Manager Products & services Planning – Capacity – Location – – Make or buy – Layout – Projects – Scheduling Controlling/Improving – Inventory Organizing – Degree of centralization – Process selection Staffing – Hiring/laying off – Use of Overtime Directing – Incentive plans – Issuance of work orders – Job assignments Table 1.6 Dr Felton Lean Slide 29: Why is Operations Management Important? Dr Felton Lean Reasons to Study Operations Management : Reasons to Study Operations Management 50% or more of the jobs in industry are operations management-related: Customer Service Quality Assurance Production Planning Scheduling Inventory Management Logistics Operations Management activities are at the core of all business organizations. All Other Functional Areas are interrelated with Operations Management Dr Felton Lean Operations as Technical Core : Operations as Technical Core Dr Felton Lean IMPORTANCE OF OPERATIONS MANAGEMENT : IMPORTANCE OF OPERATIONS MANAGEMENT Improves productivity: * Effective control of the conversion process of inputs into outputs (e.g., fewer defect output, less wastage of material inputs, effective allocation of staff, will lead to more output per unit time). ** Higher productivity leads to higher profits – How? Improves our ability to meet customer needs: * Ensure provision of high quality products and services at reasonable prices (not just cheap output) * Enables us to provide service to our target customers better than our competitors * Meeting customer needs is crucial to long term survival of the firm – Why? Dr Felton Lean IMPORTANCE OF OPERATIONS MANAGEMENT : IMPORTANCE OF OPERATIONS MANAGEMENT Central to the building of a brand name/reputation of the company/firm, as a competitive weapon: * High-quality product/service provider * Low cost/good value producer/service provider (e.g., Woolworths, Sony & Panasonic) * Fast delivery or response/lead time (e.g., Hong Kong – for 2 hrs suit tailoring Improves the living standards of citizens and wealth of nations: * Has impact on GDP per capital – high output per unit time * High-value added vs. skills needed to manufacture Dr Felton Lean Slide 34: The Overlapping of Three Major Functions Figure 1.5 Budgeting Economic analysis of investment proposals Provision of funds …… Financial indicators Competitor Customer preference Trend of technology …… Judgment of manufacturability Fulfillment lead time Dr Felton Lean OPERATIONAL-BASED COMPETITIVE ADVANTAGE : OPERATIONAL-BASED COMPETITIVE ADVANTAGE Operational based competitive advantage can be achieved by: * Doing things right the first time - Quality advantage; - defect free output, lower costs, improved competitiveness, can even lead to higher prices (e.g., Sony, Toyota, etc). * Doing things cost effectively - Cost advantage; - cost efficiency leads to price competitiveness and decent profits - Lack of cost competitiveness can lead to large-scale retrenchments * Do things fast: Speed advantage; can lose sales if slow - Reputation for speed is important Dr Felton Lean OPERATIONAL-BASED COMPETITIVE ADVANTAGE : OPERATIONAL-BASED COMPETITIVE ADVANTAGE * Change things quickly: Adaptability-advantage (ability to change from making Tea, Coffee, etc) - Change operations to meet customer demand for variety - SME Furniture manufacturer (beds, chairs, tables, sofa) * Do things right every time: Reliability-advantage - offer error-free products or services to customers EVERY time * Do things better: Service-advantage and continuous improvement (e.g., TQM – all aspects of business important in delivering quality service to customer). Dr Felton Lean Types of Manufacturing Processes (subset of OM Transformations). : Types of Manufacturing Processes (subset of OM Transformations). Conversion - iron ore to iron, mixtures to steel, crude oil to gas, etc. Fabrication - blue beads to pen tops. Assembly - parts to assemblies. Testing - in-house or on-site testing.
