+ Operations Management + Concept of Operations Management Production systems Operations Management decisions Goods Ethics versus services operations and social responsibility + Production systems The production system produces goods and services by transforming inputs into desired outputs. Since World War II operations systems have benefitted from mechanisation, automation, robotics and a huge number of technical innovations. Service industries have experienced advances in information and communication technology, which have generated increases in productivity. + Transformations Transformation is the process of taking a series of raw materials to create desired products and services. There are three key elements of an operation system: inputs processes outputs Inputs that are typical in an operation system are: human skill/effort, raw materials, facilities, machinery & equipment + Operations management decisions Strategic versus planning decisions Operations managers have to be involved in the decision making process at a strategic level. Strategic planning such as the marketing of what is produced, clearly has to go handin-hand with operations decisions such as how the product is sold. Planning decisions at the operational level include decisions about the day-to-day operations such as: What are the stock levels to be maintained? How will the production processes be scheduled? What type of layout is required for the process? What type of maintenance is required? + Role of operations manager The function of the operations manager is to coordinate the transformation of inputs into desired goods and services. The operations manager in an organisation may be known by other titles including: factory manager materials manager production manager quality manager supply officer + Goods versus services operations Many differences exist between goods and services management. Currently many modern organisations provide both goods and services. For example a record label will produce physical CDs (goods) as well as tours (services). + Ethics and social responsibilities The need for ethical and socially responsible management (ESM) applies to the operations function as it does to all functions of the organisation. Operations managers, for example, make decisions that involve elements of ethics or social responsibility – decisions that involve fair treatment of employees or the use of environmentally friendly materials. The processes used in the manufacturing processes must be in accordance with the standards set by the environment in which they operate. This means that they must adhere with the laws and regulations with regard to many different areas including the disposal of waste and emissions. + Operations Management Strategy Operations management strategy relates to choices of: Product process f acilities quality + Product choice Organisations must be able to produce a product of quality and at a cost that allows it to be marketed at a competitive price. There are five stages to new product development once an opportunity or need has been identified. In order they are: exploring and generating ideas rough screening business analysis or thorough screening prototype development testing + Product definition Product definition is the selecting and documenting of all the features of a good or service to be produced and all the inputs needed for production. The requirements for the manufacture of the products also need to be defined such as the type of machinery needed for production and the process involved. Is the product going to be a completed product or require some assembly by the customer? If so, what type of instructions will need to accompany the product? + Process choice Operations managers need to make choices about the types of technologies used, the flow of the production process and the overall capacity of the production process. The technology used to transform inputs into goods and services is known as process technology. The technology is only as good as the way it is used. Research and development (R&R) should also play a vital role in management’s planning of new process technology. + Process flow Process flow involves developing detailed specifications of the physical facilities as well as the human skills and effort required to produce the desired volume. Design and layout must accommodate the different types of production processes and organisation is likely to use. In manufacturing five types of processes can be identified: project – one-of-a-kind or customised projects job shop – small batches of different sorts of products batch – different sorts/batches of products assembly line – large volumes of a narrow range continuous flow – high volume process that runs endlessly + Quality choice Approaches to quality control: Quality control – a process or strategy for monitoring the quality of a good or a service during its production or delivery. Statistical techniques such as sampling and analysis are used. Quality assurance (QA) – the certified achievement of a level of quality in the production of a good or service. Organisations need to meet specified standards set down for their industry. Total quality management (TQM) – quality circles (teams of employees of usually four to ten people led by team leaders) meet regularly to discuss production (QA) and quality improvements, and to find solutions to workplace problems. + Total quality approach There are three central principles in the total quality approach: continuous improvement customer focus employee participation & teamwork + Continuous improvement Quality is seen as a journey rather than a destination. The principle of continuous improvement expects all employees at all levels of an organisation to seek ways to improve work performance – their own, their team’s and the performances of the whole organisation. Continuous improvement often includes benchmarking and identifying best practice in a particular production process or area of work. + Customer focus In the total quality approach, quality is based on the expectations of the customer – quality is in the eye/mind of the customer. TQM demands that all employees serve the customer. In any production process problems with quality can be prevented at the earliest stage if internal customers are treated well. Worked passed on to the stage of the process should improve the next stage. It should never make the work of the internal customer more difficult. + Employee participation and teamwork Employees are a key part of the total quality approach. The broad participation of employees in the decisions-making encourages everyone to take responsibility for quality. The aim of each employee is to eliminate errors in operations by doing right the first time (zero defects), therefore delivering quality to other employees in the process. + Planning and control The planning and control function which operations managers must undertake involves the management issues such as: inventory management production control maintenance quality control + Inventory management Inventory is an organisation’s stock of materials. The inventory that must be managed in operations are: material inputs to production (raw materials, supplies, parts) work-in-progress (unfinished goods) finished goods (not yet delivered) spare parts for machinery & equipment + Techniques Early stages of operations planning result in the development of a general guide to operations. This general guide to operations is known as a master production schedule (MPS). The MPS covers: what goods and services are to be produced the production methods to be used where production is to take place the volume to be produced when production is to take place the staff needed to do the work The MPS is used as a starting point to plan materials needs in detail. + Inventory control Inventory control takes two main forms: physical control – this involves stock, security control, physical movement of stock and regular stocktakes (physical count of stock) accounting control – this refers to maintaining a secure accounting system as well as a regular comparisons between accounting records and physical inventory. The just-in-time (JIT) approach to inventory control has been taken up by many large organisations. Under JIT inputs are delivered just before their time of use in operations (so they do not sit idle or need storage). + Production control Production control involves the careful planning and scheduling of the production process. This is done through the use of a number of scheduling techniques or the outsourcing of certain processes. Production planning and scheduling: The scheduling of the activities is another vital part of the whole production process. For example, knowing when each part of the process is going to take place, that is, exactly which day certain raw materials are going to be needed. + Dispatching Dispatching is a set of instructions that sends the inputs in the transformation process to where they are needed. Instructions can be given in many different ways. These instructions may include: verbal orders written instructions customer inputs + Scheduling techniques The planning of the schedule requires input from all parties with jobs to complete in the production process. The schedules which are most commonly used are: Gantt chart Program evaluation and review technique (PERT) Critical Path Analysis
