Operations- manufacturing and services

8.1: Introduction

bulletOperations includes both the manufacturing and services sectors.
bulletJIT (Just in Time) means a stock control system characterised by the ordering of stock as it is required. Such a system saves time on storage costs, handling costs, stocktaking, security costs and problems associated with aging stock on lines with slow turnover.

8.2: Role of operations

bulletManufacturing produces two types of products/l
bulletETMs- Elaborately Transformed Manufactures: manufactured goods that are highly processed and valued. They are complex because of the amount of processing they have undergone.
bulletSTMs- Simply Transformed Manufactures: characterised by their ability to be further processed in a wide range of processes. STMs are manufactured goods that are intermediate by nature. Due to the limited amount of transformation they have undergone, STMs have only a small amount of value added.
bulletOperations in service businesses also involve inputs, operations and outputs:
bulletInputs: knowledge, skills/expertise, information, specialised work site.
bulletOperations: provision of advice/labour/expertise/experience/time
bulletOutputs: improved quality of life, may be tangible, may be intangible

8.3: Organising operations- part one

bulletSupply chain- the range of suppliers from which the business purchases materials and resoucres.
bulletLead time- a term that describes the length of time it takes for the business to actually meet the needs of the customer through the provision of the good (or service) the customer or client seeks
bulletSupplier rationalisation- the process a business goes through when it reviews and reduces the number of suppliers it purchases from.
bulletRostering- the forming of a time-table or plan that shows the availability  of employees and their schedules of work for the business.
bulletMultiskilling- allows employees to develop skills in a wide range of tasks through ongoing training and development.
bulletScheduling and sequencing: has two main aspects- timing and sequencing (order of activities).
bulletThe main tools are the Program Evaluation and Review Technique (PERT), Critical Path Analysis (CPA) and Gantt charts.
bulletPERT and CPA diagrams show what tasks need to be done, how long they will take and what order is necessary to complete the tasks. The Critical Path is the length of time it takes to complete all tasks necessary to complete the process or project. Some tasks can be performed simultaneously, while others need to be started after other tasks are complete.
bulletA Gantt chart outlines the activities that need to be performed, the order they should be performed in and how long each activity is expected to take.

8.4: Organising operations- part two

bulletTask design involves classifying job activities in ways that make it easy for an employee to perform and complete the task successfully.
bulletRecruitment can only take place after task design:

    Task design    -    job description    -    person specification     -    recruitment

bulletPlant/office layout may be:
bulletProduct layout- generally used in mass production with an assembly line.
bulletProcess layout- machines performing similar functions are grouped together.
bulletMost offices are organised around workstations- desk areas required by office workers, usually fitted with access to a computer monitor, keyboard, telephone, mouse and mousepad, storage and close access to fax and printer.
bulletWarehousing refers to the storage of raw materials and inventories.

8.5: Organising operations- part three

bulletTechnology has transformed the way businesses operate. Since technology is usually expensive businesses need to decide whether to buy or lease.
bulletOffice technology includes: computers & related equipment, modem & network technology, mobile phones, answering machines, fax, EFTPOS etc.
bulletTechnolology has allowed for telecommuting- to commute or travel to work, electronically. This means that home becomes the work site and work is delivered via modem and e-mail or the internet.
bulletRobotics applies to highly specialised forms of technology capable of complex  tasks.
bulletComputer aided design (CAD) is a computerised design tool that allows business to create product possibilities from a series of input parameters.
bulletComputer aided manufacture (CAM) is software that controls manufacturing processes. 

8.6: Control of operations

bulletStocktake involves the physical counting of goods to determine how much of each stock item the business has on hand at a certain point in time.
bulletDownsizing is the process whereby a business reduces staff numbers.
bulletQuality Assurance- a pre-control process that ensures quality of inputs before processing- it is proactive and preventative.
bulletQuality control- series of controls designed to bring attention to areas where quality parameters are not met.
bulletTQM (Total Quality Management)- ensuring all practices in a business are the best they can be. It is based on a principle called Kaizen, a Japenese word meaning continual improvement. The 4 main principles of TQM are:
bulletKaizen: continuous improvement
bulletprevention (assurance rather than controls)
bulletfocus on the customer/client
bulletwhole-business responsibility (all people can contribute to improved quality practices).
bulletBenchmarking: the setting of industry-wide standards of best operation and processing practices.
bulletRecords management involves collecting data about the business and it operations.
