operations processes Flashcards
(35 cards)
inputs
- labour
- energy
- raw materials
- machinery and technology
capital-labour substitution
machinery and tech replacing people by doing the work they do
transformed resources
- materials + intermediate goods
- information (internal + external)
- customers (needs & feedback)
transforming resources
- human resources
- facilities
materials (transformed resource)
- raw materials: wood or steel
- intermediate goods: goods manufactured and used in further processing
information (transformed process)
- external info: comes from outside the business as: market reports, media reports or gov stats
- internal info: comes from within the business as: financial reports, quality reports & KPIs e.g lead times, inventory turnover & production data
customers (transformed resource)
customers become transformed resources when their choices, needs & wants shape inputs
Facilities (Transforming resources)
- number of facilities to be used
- location & its capacity
- zoning and restrictions
- energy and water reqs
- optimum plant design and process layout
zoning
dividing of an area into zones to restrict the number and types of buildings and their uses
process layout
the arrangement of machines such that the machines and equipment are grouped together by the function they perform
influence of Volume
- mass production involves high volume: repetition in tech
- good volume flexibility: shorter lead times
- mismanagement leads to overproduction which causes wastage and increased inventory
influence of variety
range of goods and services offered by a bus
- mix flexibility is the mix of products made, or services delivered through the informations process
- the greater the variety offered, the more the ops process needs to alow for greater variation
influence of variation
variation is demand is about the amount of products desired by consumers
- an increase in demand requires an increase in inputs, HR, energy use: fast suppliers, flexible labour and high energy sources
failure to meet increased demand can result in production delays leading to loss of sales as consumers purchase elsewhere - important for businesses to forecast and quickly react to changes in demand
influence of visibility (customer contact)
customer contact or feedback and their preferences shape what businesses make as they maximise sales
- customer contact can be direct (surveys, interviews) or indirect (sales data, market share)
- visibility and success of competitors plays an important role
sequencing (helps w organising and ordering)
the order in which activities in the operations process occurs i.e order in which tasks need to be performed
scheduling (helps w organising and ordering)
length of time activities take within ops process i.e time required for each task in the assembly process
scheduling tools
Gantt Charts and Critical Path analysis (CPA)
Gantt Charts
bar chart that shows both scheduled and completes work over a period of time
- forces managers to plan the steps needed to complete a task
- specify the time required for each task and makes it easy to monitor actual progress against planned activities
Critical Path Analysis
A scheduling method that shows what tasks need to be done, how long they’ll take and the order to complete those tasks
Technology (In the transformation process)
- increases the quality of products, allowing businesses to charge a higher price on their products
- shortens the production process and encourages the better use of raw materials, allowing ops process to be more cost-effective
types of tech in the transformation process
office tech (computers, keyboards) manufacturing tech (robotics, computer aided design)
task design
involves classifying job activities in ways that make it easy for an employee to successfully perform and complete the task.
workplace/plant layout
arrangement of equipment, machinery and staff within the facility. largely influenced by level of customisation and quantity of goods/services. O.M manager needs to consider the best layout to ensure:
- enough physical space for volume of production
- effective use of equip + tech to minimise waste + cost
process layout
arrangement of machines such that the machines and equipment are grouped together by the process they perform : allowing for specialised production processes
- deals with high-variety, low-volume production. Each product has a different sequence of production and the production is intermittent, moving from one dep to another
