BAM 199 NOTES Operations - responsible for producing goods and/or providing services. THREE BASIC FUNCTIONAL AREAS IN AN ORGANIZATION 1. FINANCE -securing financial resources 2. OPERATIONS -producing goods/providing services 3. MARKETING -selling and promoting Operations Management Customer contact Labor content Uniformity of input Measurement of productivity Opportunity to correct problems before delivery Inventory Wages Patentable - management of systems or processes that are part of the operations that will create goods and/or provide services - involves operating decisions related to product and service design, capacity planning, process selection, work management, inventory and supply management, production planning, quality assurance, scheduling, and project management. Low High Low High High Low Easy Difficult High Low Much Narrow range Usually Little Wide range Not Usually SIMILARITIES: a. Forecasting and capacity planning to match supply and demand. b. Process Management c. Managing variations d. Monitoring and controlling costs and productivity e. Managing the supply chain Production of goods results in tangible output Delivery of service generally implies an act. goods are produced and services are performed. f. Location planning, inventory management, quality control and scheduling process - consists of one or more actions that transform inputs into outputs DIFFERENCES Characteristic Output Goods Services Tangible Intangible Process management - is a discipline in operations management in which people use various methods to discover, model, analyze, measure, improve, optimize, and automate business processes. 3. Random variation - natural variability present to some extent in all processes Three Categories of Business Processes: 1. Upper-management processes 4. Assignable variations - govern the operation of the entire organization - caused by defective input, incorrect work methods, out of-adjustment equipment, and so on. 2. Operational processes - core processes that make up the value stream 3. Supporting processes Operations Function requires both the strategic and day-to-day production of goods. - support the core processes Role of the Operations Manager: Two Major Aspects of Process Management - guide the system by decision making 1. Managing a Process to meet Demand - key figure in the system Supply > Demand = Wasteful, Costly Supply < Demand = Opportunity loss, Customer dissatisfaction Supply = Demand = Ideal - responsibility for the creation of goods and provision of services - responsible for managing all the activities that are part of the production of goods and services. 2. Process Variation There are four basic sources of variation: 1. The variety of goods or services being offered - greater the variety of goods and services, the greater the variation in production or service requirements System design – strategic decisions that usually require long-term commitment of resources System operation – tactical and operational decisions 2. Structural variation in demand - includes trends and seasonal variations which are generally predictable supply chain is the sequence of organizations, including their facilities, functions, and activities, that are involved in producing and delivering a product or service. 3. Performance Metrics - to manage and Typical operations decisions include: 4. Analysis of Trade-offs - analyzing the advantages and disadvantages What: What resources are needed, and in what amounts? When: When will each resource be needed? When should the work be scheduled? When should materials and other supplies be ordered? control operations 5. Degree of Customization - higher degrees of customization involve more complexity in terms of production, layout, worker skills and productivity. Where: Where will the work be done? How: How will the product or service be designed? How will the work be done? How will resources be allocated? 6. Systems Approach – emphasizes interrelationships among subsystems Who: Who will do the work? 7. Establishing Priorities - certain issues or items are more important than others General Approaches to Decision Making 1. Model - an abstraction of reality; a simplified representation of something Classified as: Physical models look like their reallife counterparts Schematic models are more abstract than their physical counterparts such as graphs and charts, blueprints, pictures, and drawings. Mathematical models are the most abstract such as numbers, formulas, and symbols. 2. Quantitative Approaches - frequently seeks to obtain a mathematically optimal solution to certain managerial problems Pareto Phenomenon ­ ­ one of the most important and pervasive concepts in operations management. states that 20% of the things done in the right manner produce 80% of the desired results. It works on the concept of first segregating the “vital few” from the “trivial many” and then working on those “vital few” to achieve the best results. Key Issues for Today’s Business Operations Economic conditions – recession, slow recovery in various sectors Innovating – finding new or improved products or services Quality problems – due to operations failures Risk Management – financial crises, product recalls, accidents, natural and manmad disasters, and economic ups and downs Cyber-security – need to guard against intrusions from hackers Competing in a global economy – outsourcing, reducing costs internally, changing designs, and working to improve productivity. The following areas require more in-depth discussions: Environmental Concerns - Stricter environmental regulations are being imposed. Business organizations are under increasing pressure to generally operate sustainable processes. Sometimes referred to as “green initiatives”. Ethical Conduct – Ethics – a standard of behavior that guides how one should act in various situations. Many organizations have developed codes of ethics to guide employees’ or members’ conduct. The Markula Center for Applied Ethics at Santa Clara University identifies five principles for thinking ethically: 1. The Utilitarian Principle – the good done by an action or inaction should outweigh any harm it causes or might cause. 2. The Rights Principle – actions should respect and protect the moral rights of others 3. The Fairness Principle – equals should be held to, or evaluated, by the same standards 4. The Common Good Principle – actions should contribute to the common good of the community 5. The Virtue Principle – actions should be consistent with certain ideal virtues E-business (electronic business) involves the use of the internet to transact business. It is changing the way business organizations interact with their customers and their suppliers. Lean Systems are systems that use minimal amounts of resources to produce a high volume of high-quality goods with some variety. Lean systems use a highly skilled workforce and flexible equipment. The famous Toyota, Nike and Intel were just few of the successful companies that currently use lean processes. Production is defined as ‘the step-by-step conversion of one form of material into another form through chemical or mechanical process to create or enhance the utility of the product to the user’ production system - the step-by-step conversion of one form of material into another form through chemical or mechanical process to create or enhance the utility of the product to the user Examples of a Production System Tangible goods Intangible goods Differentiate the different classification of production system Job-shop production ­ ­ characterized by manufacturing one or few quantity of products designed and produced as per the specification of customers within prefixed time and cost. low volume and high variety of products. Characteristics: a. High variety of products and low volume. b. Use of general purpose machines and facilities. Advantages: Variety of products can be produced; Learning opportunities to workers resulting to becoming more skilled and competent; Full potential of operators can be utilized; Opportunity exists for creativity and innovation. Disadvantages: Higher cost due to frequent set-up changes; Higher level of inventory at all levels and hence higher inventory cost; Production planning is complicated. Larger space requirements. Batch Production ­ c. Highly skilled operators who can take up each job as a challenge because of uniqueness. d. Large inventory of materials, tools, parts. e. Detailed planning is essential for sequencing the requirements of each product, capacities for each work center and order priorities. ­ ­ ­ types of production most commonly used in consumer durables, FMCG or other such industries where there are large variety of products with variable demands takes place in batches manufacturer already knows the number of units he needs to a manufacturer and they are manufactured in one batch. Examples of batch production include Biscuits, confectionaries, packaged food items etc. Characteristics: a. Shorter production runs. b. Plant and machinery are flexible. c. Plant and machinery set up is used for the production of item in a batch and change of set up is required for processing the next batch d. Manufacturing lead-time and cost are lower as compared to job order production. Advantages Better utilization of plant and machinery Promotes functional specialization. Cost per unit is lower as compared to job order production. Lower investment in plant and machinery. Flexibility to accommodate and process number of products. Job satisfaction exists for operators. Disadvantages: Material handling is complex because of irregular and longer flows. Production planning and control is complex. Work in process inventory is higher compared to continuous production. Higher set up costs due to frequent changes in set up. Mass Production ­ ­ ­ ­ Manufacture of discrete parts or assemblies using a continuous process justified by very large volume of production machines are arranged in a line or product layout Product and process standardization exists and all outputs follow the same path. Characteristics: a. Standardization of product and process sequence. b. Dedicated special purpose machines having higher production capacities and output rates. c. Large volume of products. d. Shorter cycle time of production. e. Lower in process inventory. f. Perfectly balanced production lines. g. Flow of materials, components and parts is continuous and without any back tracking. h. Production planning and control is easy. i. Material handling can be completely automatic. Advantages Higher rate of production with reduced cycle time; Higher capacity utilization due to line balancing; Less skilled operators are required; Low process inventory; Manufacturing cost per unit is low. Disadvantages: Breakdown of one machine will stop an entire production line. Line layout needs major change with the changes in the product design. High investment in production facilities. The cycle time is determined by the slowest operation. Continuous Production ­ ­ Production facilities are arranged as per the sequence of production operations from the first operations to the finished product items are made to flow through the sequence of operations through material handling devices such as conveyors, transfer devices, etc Characteristics: a. Dedicated plant and equipment with zero flexibility. b. Material handling is fully automated. c. Process follows a predetermined sequence of operations. d. Component materials cannot be readily identified with final product. e. Planning and scheduling is a routine action. Advantages Standardization of product and process sequence; Higher rate of production with reduced cycle time; Higher capacity utilization due to line balancing; Manpower is not required for material handling as it is completely automatic. Person with limited skills can be used on the production line. Unit cost is lower due to high volume of production. Disadvantages: Flexibility to accommodate and process number of products does not exist. Very high investment for setting flow lines. Product differentiation is limited. Strategic planning is the process of thinking through the current mission of the organization and the current environmental conditions facing it, then setting forth a guide for tomorrow’s decisions and results. Strategic planning is built on fundamental concepts: that current decisions are based on future conditions and result. Know different strategic planning approaches and forced-choice model. Henry Mintzberg suggests three contrasting modes of strategic planning: the entrepreneurial, the adaptive, and the planning modes. 1. Entrepreneurial Model ­ approach in which strategy is formulated mainly by a strong visionary chief executive who actively searches for new opportunities, is heavily oriented toward growth, and is willing to make bold strategies rapidly ­ entrepreneurial searches for new mode are most likely to be found in organizations that are young or small, have a strong leader, or are in such serious trouble that bold are their only hope. 2. Adaptive Mode ­ used by managers in established organizations that face a rapidly changing environment and yet have several coalitions, or power blocks, that make it difficult to obtain agreement on clear strategic goals and associated long-term plans. ­ degree of innovation fostered by the strategic management process is likely to depend on the ability of managers to agree on at least some major goals and basic strategies that set essential directions. 3. Planning Mode ­ approach to strategy formulation that involves systematic, comprehensive ­ ­ analysis, along with integration of various decisions and strategies utilize planning specialists to help with the strategic management process. The ultimate aim of the planning mode is to understand the environment well enough to influence it. innovation is most likely to occur when strategies explicitly articulate needs for product and service innovation and when toplevel managers help integrate efforts in the direction of encouraging innovation. Forced-Choice Model ­ ­ ­ considered to be the simplest process. usually used by new businesses or organizations with less experience in strategic planning and development Six to twelve members of upper management are involved in this process. The first step is to perform organization assessment which includes financial goals, Strengths and weakness analysis, short term operations plans and future goals. Then an environmental analysis is performed in step two which include economy, regulations, competitors etc. Based on these assessments, strategies are developed.
