operations process Flashcards
Inputs
are the components used in the transformation process (eg. labour, energy, materials, machinery and technology)
Transformed resources
Inputs that are changed during the transformation process (eg. paint splashed across canvas)
MIC
material, information, customers
Materials
are raw materials or intermediate goods
Raw materials are unprocessed (eg. wood)
Intermediate goods are semi-finished and will be manufactured further (eg. flour used to make bread)
Information
defines how each input is used and where it’s sourced from. It can be from either internal or external sources.
example: a clothing manufacturer could look through a list of suppliers (information) to find the best fabric
a barber needs to know customer preferences (information) before cutting their hair
Internal sources: financial statements, employee knowledge, market research, sales reports
External sources: Australian Bureau of Statistics, scientific studies
Customers
Customer choice define a business’ goods and services through customer orientation
Customers are transformed through use of goods or service delivered.
Example: an exercise machine can help lose weight (goods) and a haircut can change the look of hair (services)
Transforming resources
Inputs that perform the transformation process. They are either human resources or facilities.
Human resources
Employees that design, create and deliver products. They are:
- The most valuable asset of the business
- Responsible for combining other resources to create goods and services
- Should be motivated and skilled -> makes transformation efficient and effective (fewer accidents and absences, less waste, faster completion times, higher volume production)
Facilities
Plants and machinery used to carry out the transformation process.
A plant can be a factory or an office
A machinery can be technology (eg. robots) or equipment (eg. forklift)
When it comes to facilities, businesses need to decide on:
- Location
- Size
- Layout
When it comes to machinery, businesses need to decide on:
- Type
- Amount
- Extent to which it will be used
4 V’s
The 4 V’s are factors that shape operations processes. These are driven by customer demand in the market.
They are volume, variety, variation in demand and visibility
A business with high volume, but low variety, variation in demand and visibility will keep production costs low.
A business with low volume, but high variety, variation in demand and visibility will keep production costs high.
Volume
refers to the amount of output that will be produced. The main driver of volume is consumer demand.
However, it can also be affected by inputs such as supply of raw materials and labour, size of manufacturing plants and amount of technology or information available
Example:
A 5 star restaurant uses high quality inputs and smaller customer base
A fast food company uses cheaper inputs and large customer base
Effects on production: volume flexibility
Operations need to have volume flexibility, i.e. how quickly the production process can adapt to changes in demand
- Slow response to falling demand -> overproduction -> high inventory costs and wastage
- Slow response to rising demand -> underproduction -> lost sales and profits
- If this is balanced right, businesses can shorten lead times (time taken from customer order to product delivery)
Variety
refers to the range of products that a business offers.
Example: a small clothing boutique will have high variety and a clothing factory will have low variety
Effects on production: variety
The more variety, the more that operations has to adapt. With larger variety comes more inputs (wider range of materials) and larger range of transformation processes (more facilities)
If a clothing company wants to sell shoes, they need to:
• Source new materials e.g. leather and glue
• Expand their plant to allow for more product volume
• Bring in machinery designed for shoe making
Variation in demand
refers to how much market demand will change and how operations can respond to these changes
Example:
High variation: an air conditioning manufacturing will have high demand in summer
Low variation: a café will have consistent demand throughout the year
Effects on production: variation in demand
To manage variation, businesses need to be able to anticipate changes in demand and be flexible
Rising demand requires: Supplier (more inputs) Labour (more employees) Energy (more energy) Machinery (efficient machinery)
Falling demand requires:
Reduced staff hours
Slower production
It can be hard to respond if:
Suppliers -> cannot supply on time
Labour -> inflexible, unskilled or unavailable
Energy -> not enough available
Machinery -> cannot adjust to increase in capacity
Example:
there is high demand for toys during Christmas, so high production is required during Christmas
there is low demand for sweaters during summer, so low production is required during summer
Visibility
refers to the level of customer contact businesses have and the extent to which this influences their operations process.
Example:
A hairdresser will have high visibility because customers decide on output
Production of office supplies will have low visibility because of not much input; standardised
Effects on production: visibility
Marketing: Consumer needs and wants (customer feedback) shape the products that businesses create
Operations: The business decides how much customer input there should be.
Therefore, operations and marketing managers should work together to shape which goods and services the business offers
Customers affect all 4 V’s of production!
4 V’s: Effects on production costs
High volume lowers cost because it achieves economies of scale (as production increases, cost per unit of production falls)
Low variety reduces cost because business requires smaller range of inputs and transformation processes
Low variation in demand reduces cost because of reduced need for flexible production
Low visibility reduces cost because less time and resources is spent on gathering customer input. Also, rent costs can be reduced because the business doesn’t need a central location easily accessible by customers.
Sequencing
The order of activities in the operations process
For example: If Valentine’s day was coming up, the chocolate manufacturer will first order materials, secondly prepare and package, last deliver and selling the chocolates
Scheduling
refers to the time taken to complete activities in the operations process.
For example: the chocolate manufacturer may have to wait for two month for their materials to arrive, one month for preparing and packaging and one week for delivery to retailers
Sequencing and scheduling
refers to planning tools for coordinating the operations process and boosting efficiency
Aims of sequencing and scheduling include:
Provide a sense of direction and organisation to make sure everything runs smoothly
Allow adjustments to be made when there are hold-ups, so that completion time is not affected
Gantt chart
Gantt charts outline each step in the operations process, the order in which they will be done, and the time need for each step
Best used when the operations process includes a number of steps that need to be completed to produce an output, i.e. simple tasks and complicated projects
Advantages:
Simple to use
Provides operations managers with a quick overview of their schedule
Encourages managers to plan ahead
Makes it easier to monitor actual progress against plans
Disadvantages:
Not suitable for complex projects
Critical path analysis
Critical Path Analysis (CPA) outlines the activities that need to be done, how long each activity takes, and the best order in which to complete them
Critical Path: minimum length of time needed to complete all activities in a project
Tip: in exams, ALWAYS choose the longest path
Advantages - CPA shows:
How each activity is interrelated
Which activities can be done at the same time
Which activities are the most important in terms of overall time (activities within CPA can be prioritised so that the most important activities are completed first)
Disadvantages:
Not suitable for complex projects
If time estimates are incorrect, there will be major delays
