Q

Cost and volume objectives

A
  • Business needs to ensure that operations are cost-effective
  • Traditional measures of cost-effectiveness is “unit cost” (total costs divided by total units)
  • Businesses in the same industry face similar cost structures, but each varies in terms of productivity, efficiency and scale of production
  • The business with the lowest unit cost is in a strong position to be able to compete by being able to offer the lowest price of make the highest profit margin

Examples:
- Productivity & Efficiency (e.g. units per week or employee
- Unit cost per item
- Contribution per unit
- Number of items produce (per time period or per machine)

Q

Efficiency & Flexibility objectives

A
  • Closely linked to cost targets
  • Look at how effectively the assets of the business are being utilised
  • Also measure how responsive the business can be to short-term or unexpected changes in demand
  • Efficiency and flexibility are key determinates of unit costs

Examples
- Labour productivity
> Output per employee, units produced per production line and sales per shop
- Capacity utilisation
> The proportion of potential output actually being achieved
- Order lead times
> The time taken between receiving and processing an order
- Output per time period
> Potential output per week on a normal shift basis; potential output assuming certain levels of capacity utilisation

Q

Internal influences on operational objectives

A

Corporate objectives
- As with all the function areas corporate objectives are the most important internal influence as operations objectives should not conflict with corporate objectives

Finance
- Operations decisions often involve significant investment and cost
- The financial position of the business directly affects the choices available

Human resources
- For a services business in particular the quality and capacity of the workforce is a key factor affecting operations objectives. Targets for productivity will be affected by the investment in training and the effectiveness of workforce planning

Marketing issues
- The nature of the product determines the operational set-up
- Regular changes to the marketing mix may place stains on operations, particularly if production is relatively inflexible

Q

External influences on operational objectives

A

Economic environment
- Crucial for operations. Sudden or short term changes on demand impact on capacity utilisation and productivity. Changes in interest rates impact on the cost of financing capital investment in operations

Competitor efficiency flexibility
- Quicker, more efficient or better quality competitors will place pressure on operations to deliver at least comparable performance

Technological change
- Also very significant especially in markets where product life cycles are short, innovation is rife and production processes are costly

Legal & environmental change
- Greater regulation and legislation of the environmental places new challenges for operations objectives

Q

Capacity is a dynamic concept

A

Capacity can change
- E.g. when a machine is having maintenance, capacity is reduced
- Capacity is linked to labour e.g. by working more production shifts, capacity can be increased

Capacity needs to take account of seasonal or unexpected changes in demand
- E.g. chocolate factories need capacity to make easter eggs in December before shipping to shops after Christmas
- E.g. Ice cream factories in the UK needed to quickly increase capacity during a heat wave

Q

Why capacity utilisation matters

A
  • It is a useful measure of productive efficiency since it measures whether there are unused (idle) resources in the business
  • Average production costs tend to fall as output rises - so higher utilisation can reduce unit costs, making a business more competitive
  • Businesses ai to produce as close to full capacity as possible in order to minimise costs
  • A high level of capacity utilisation is required if a business has a high break-even output due to significant fixed costs of production

Q

The costs of capacity

A

Since capacity is all about the output a business can achieve, it is easy to see what costs are involved in making that capacity available

The key cost of capacity:
- Equipment - e.g. production line
- Facilities - e.g. building rent
- Labour - wages and salaries of employees involved in production or delivering a service

25
Dangers of operating at low capacity utilisation
- Higher unit costs - impact on competitiveness - Less likely to reach breakeven output - Capital tied up in under-utilized assets
26
Can a business work at more than 100% capacity utilisation
- Can be possible in the short-term - Increase workforce hours > Extra shifts; encourage overtime; temporary staff - Sub contact some production activities - Reducing time spent maintaining production equipment
27
Problems working at a high capacity
- Negative effect on quality (possibly) > Production is rushed > Less time for quality control - Employees suffer > Added workloads & stress > De-motivating if sustained for too long - Loss of sales > Less able to meet sudden or unexpected increases in demand > Production equipment may require repair
28
Evaluation on capacity
- In general high capacity utilisation is better than low - Capacity has a cost - it needs to be used - Flexibility of capacity is also important: the ability to adjust to meet changes in demand
29
What is lean production
An approach to management that focuses on cutting waste, whilst ensuring quality. This approach can be applied to all aspects of business - from design, through production to distribution
30
Lean production in a nut shell
- Doing the simple things well - Doing things better - Involving employees in the continuous process of improvement - And as a result, avoiding waste and therefore reducing costs
31
Why business need to cut out waste
WASTE = COST
32
Examples of waste in business
Over production - Making more than is needed: leads to excess inventories which may then become unsalable Waiting time - Equipment and people standing idle waiting for a production process to be completed or resources to arrive Transport - Moving resources around unnecessarily Stocks - Often held as an acceptable buffer, but should not be excessive Motion - A worker who appears busy but not actually adding any value Defects - Output that does not reach the required quality standard - often a significant cost to an uncompetitive business
33
Effective lean production requires
- Good relationship with suppliers - Committed, skilled and motivated employees - A culture of quality assurance; continuous improvement & willingness to embrace change - Trust between management and employees
34
Various methods of lean production
- Time based management - Simultaneous engineering - Just in time production (JIT) - Cell production
35
Time based managment
A general approach that recognises the importance of time and seeks to reduce the level of wasted time in the production processes of a business
36
Benefits of effective time management
- Quicker response times to meet changing market and customer needs - Faster new product development - Reduction in waste, therefore greater efficiency
37
Requirements for time based managment
- Flexible production methods > Able to change products quickly > Can change production volumes/ runs - Trained employees > Multi skilled staff > Trust between workers and managers
38
Simultaneous engineering
- An approach to project management that helps firms develop and launch new products more quickly - All parts of the project are planned together. Everything is considered simultaneously rather than separately
39
Benefits of simultaneous engineering
- New product is brough to the market much more quickly - Business may be able to charge a premium price that will give a better profit margin and help recoup R&D costs - A greater sense of involvement across business functions improve staff commitment to the project - Can be a source of competitive advantage for the firm if it can get a reliable new product into the market and build brand loyalty before its competitors
40
Cell production
A form of team working where production processes are split into cells. Each cell is responsible for a complete unit of work
41
Benefits of cell production
- Closeness of cell members should improve communication - Workers become multiskilled and more adaptable to the needs of the business - Greater employee motivation from variety of work, team working and responsibility - Quality improvements as each cell has 'ownership' for quality on its area
42
Potential drawbacks of cell production
- Culture has to embrace trust & participation or workers can feel they are being pushed for greater output with no respite - Business may have to invest in new materials handling and ordering systems suitable for cell production - Cell production may not allow a firm to use it machinery as intensively as in traditional flow production - Some small scale production line may not yield enough savings to make a switch to cell production worthwhile - Allocation of work to cells has to be efficient o that employees have enough work, but not so much that they are unable to cope
43
Just in time
JIT aims to ensure that inputs into the production process only arrive when they are needed
44
How does JIT work
-Based on a pull system of production - customer orders determine what is produced - Requires complex production scheduling- achieved using specialist software to connect production dept with suppliers - Supplies delivered to production line only when needed - Requires close cooperation with high-quality suppliers
45
Benefits of JIT
- Lower stock holding means a reduction in storage space which saves rent and insurance costs - As stock is only obtained when it is needed, less working capital is tied up in stock - Less likelihood of stock perishing, becoming obsolete or out of date - Less time spent on checking and re-working production as the emphasis is on getting the work right first time - Improves firms liquidity
46
Drawbacks of JIT
- There is little room for mistakes as minimal stock is kept for re-working faulty product - Production is highly reliant on suppliers and if stock is not delivered on time, the whole production schedule can be delayed - There is no spare finished products available to meet unexpected orders, because product is made to meet actual orders - A need for complex, specialist stock systems
47
Summary of JIT
- No buffer stocks of any type are held - No production is to order - Stocks are ordered only when is needed - No spare workers are employed - Staff are multi-skilled and capable of filling on for their absent colleagues - It is used by lean producers
48
JIT Vs JIC
- Just in case used to be the system operated by firms for stock - Additional stock was kept JIC for example: > There was a sudden increase in demand > Some of the current stock was defective > Stock deliveries didn't turn up - JIC raised costs because of increased storage costs; for stock deteriorating/ perishing or being stolen
48
Customer define quality
- Quality is about meeting the needs and expectations of customers - Customers needs & expectations: > Performance (fit for purpose) > Appearance > Availability & delivery > Reliability/ durable > Price/ value for money - If a product or service meets all those standards then it passes the quality test - If it doesn't then it is sub-standard
48
Definition of quality
A product or service is of good quality if it meets the needs and expectations of the customer
49
Measures of quality
Tangible - Reliability - Function & features - Support levels & standards - Cost of ownership (e.g. repairs) Intangible - Brand image - Exclusiveness - Market reputation
50
Whys is quality so important in business
- Markets are highly competitive - Customers are more: > Knowledgeable & demanding > Prepared to complain about poor quality > Able to share information about poor quality - If a business can develop a reputation for high quality then it may be able to create an advantage over its competitors
51
Business benefits of greater quality
- Customer satisfaction - Repeat purchase - Customer recommendation - Lower marketing costs - High customer loyalty
52
Quality and competitiveness
- Fewer businesses are competing solely on price - At a similar price, the higher-quality product is likely to win - Quality can enable a business to differentiate its product from the competition
53
Examples of poor quality
- Product fails - e.g. a breakdown or unexpected wear and tear - Product does not perform as promised - Product is deliver late - Poor instructions/ directions for use - Unresponsive customer service
54
Costs of poor quality
- Lost customers - Cost of reworking or remaking product - Costs of replacements or refunds - Wasted materials - Poor quality is a source of competitive disadvantage - If competitors are achieve higher quality, then a business will suffer
55
How good/ poor quality is measured
- Customer service ratings - Product return - Warranty claims - Rejected output from production - Levels of repeat business - Market surveys - Profit margins
56
How poor quality damages competitiveness
- Financial costs (e.g. compensation) - Lost customer loyalty - Damaged business reputation - Need for greater controls and checks - Competitors take advantage
57
Quality managment
- Achieving high quality does not happen by accident Quality management is concerned with controlling activities with the aim of ensuring that products and services are fit for their purpose and meet the specifications Two main approaches - Quality control > Based on inspection > Takes defects out - Quality assurance > Based on processes > Build quality in
58
Definition of quality control
The process of inspecting products to ensure that they meet the required quality standards
59
Quality control overview & Pros/ Cons
- Traditional way of managing quality - Concerned with checking and reviewing output - Mainly about "detecting" defective output - rathe than preventing it - Can be a very costly process Pros - Ensures bad products do not reach public - Responsibility only rests with one trained individual Cons - Does not encourage others to take responsibility - High levels of waste
60
Quality control & Inspection
- When raw material are received prior to entering production - Whilst products are going through the production process - When products are finished - takes place before products are despatched to customers
61
Problems with quality inspections
- Costly - Often at the end of the production process - potentially too late - Inconsistent inspections - Often not compatible with modern production systems - Done by inspectors rather than workers themselves
62
Quality assurance
The processes that ensure production quality meets the requirements of customers - How a business can design the way a product or service is produced or delivered to minimise the chances that output will be sub-standard - Focus of quality assurance is on the product design/development stage > If the production process is well controlled then quality will be "built-in" > If the production process is reliable - there is less need to inspect production output - Self checking - Modern method - Encourages responsibility - Get it right first time - Less waste - Higher level of quality - All staff trained
63
Quality Assurance Vs Quality control
Quality assurance - Focuses on processes - Achieved by improving production processes - Targeted at the whole organisation - Emphasises the customer - Quality is built into the product Quality control - Focus on outputs - Achieved by sampling & checking (inspection) - Targeted at production activities - Emphasises required standards - Defect products are inspected out
64
Advantages and disadvantages of quality assurance
Advantages - No waste, cost saving - Motivated staff - No need for reworking - Quality should increase Disadvantages - Cost of training staff - Not all staff may wish to take on responsibility
65
Evaluating quality improvements
Potential challenges - Culture may need change - Poor quality likely to be the result of multiple issues - Potential high cost: training, new processes, information systems Evaluation - Can a business afford not to address poor quality - Quality is hard to improve in the short term - Competitors don't stand still
66
How to improve quality
- Identify the problems with market research - R&D identifying new improved products and production methods - Kaizen group, staff identify small changes to improve the product or production process - Quality circles, autonomous groups of workers who are responsible for their own decisions
67
Kaizen
- Kaizen (or continuous improvements) is an approach of constantly introducing small incremental changes in a business in order to improve quality and/or efficiency - This approach assumes that employees are the best people to identify room for improvements since they see the process in action all the time. A firm that uses this approach therefore has to have a culture that encourages and rewards there employees for contribution to the process - All staff are encouraged to make suggestions and may be finically rewarded for successful ideas - Kaizen requires managers to listen to workers and changes this requires training for managers and a change in culture
68
Impact of kaizen
- Better motivated staff as they feel they are being listened to and have greater responsibly - Costs saving in production, kaizen should result in less mistakes, less waste and goods being produced quicker - Kaizen should also result in better
69
Quality circles
- Groups of workers who are multi-skilled and can cover for each other - They take responsibility for their own quality regularly discuss how to improve quality - The should result in high levels of motivation and high levels of motivation and high quality products
70
TQM (Total quality management)
- The main aim of TQM is to get it right first time and reduce waste. TQM should result in zero defects - With TQM everyone is responsible for quality not just managers. All work colleagues should be treated as a customers and therefore treated with value and respect. TQM also has a focus on continuous improvement this is know as Kaizen - TQM regards teamwork and teams as the best way of solving problems - TQM is a top down process which requires managers to completely accept all staff are important and have a voice - Firms need to also build close relationships with their suppliers to ensure quality suppliers
71
Advantages of TQM
- Puts customer at heart of production process - Motivational since workers feel more involved and are making decisions - Less wasteful than throwing out defective finished products - Eliminates cost of inspection
72
Disadvantages of TQM
- Requires strong leadership - often missing in business - Substantial investment in training & support - but return on investment not immediate - May become bureaucratic - Disruptions and costs may outweigh benefits
73
Quality improvements benefits
- Improved staff morale, higher productivity and lower labour turnover - Competitive advantage in the market place.
74
Quality improvements difficulties
- Balancing the cost of improving quality against the benefits of quality - Companies that outsource their goods can struggle to ensure quality
75
Influences on the choice of supplies
Price - Often considered the most important, value for money is crucial - Lowest price isn't always best value, depends on quality Quality - Consistently high quality, right product at the right time Reliability - Delivers correct product on time - Goods and services work as described Communication - East to communicate with - e.g. place orders, build relationship Capacity - Able to handle increased volumes of supply, perhaps short notice Financially secure - Long term trading relationships requires suppliers to stay in business - More likely to offer better payment terms
76
Why are suppliers important
- Meets the needs and wants of customers for a business, it needs effective "supply chains" - Suppliers determine many costs of a business - Suppliers closely linked to product quality - Suppliers can be a source of finance to a business - Key relationships are needed especially for business that use lead production and JIT
77
Managing supply chain
- Some firms take an aggressive approach with suppliers encouraging competition between rival suppliers to lower their price and improve delivery time - Some firms build long term relationships with there suppliers
78
Importance of supplier price
- Suppliers must offer good value for money prices - Supplier prices can be lowered by: > Grouping purchases with fewer suppliers > Ensure suppliers compete against each other for regular orders
79
Strategic Vs commodity suppliers
- Some suppliers are strategically crucial to a business - Strategic = the business cannot succeed without maintaining good relationship with suppler. These goods are crucial to a businesses success - Commodity suppliers provide goods that can be easily brought elsewhere
80
What is an organisational structure
Shows how people and management are organised in business
81
Organisational structure reflects
- Authority and responsibility - who is responsible for who and who is in charge
82
Factors that influence organisational structure
Size of business - Small businesses will tend to have informal or flat hierarchal structures - Large business have more complicated structures involving more layers Type of business - Does the business operate in one or several locations - Is the business in the service or manufacturing sector - Is the workforce highly skilled or not Management or leadership style - An autocratic leadership style will lead to a different structure compared to one who prefers to delegate responsibility The competitive environment - Organisation structure are influenced and changed by development in the market
83
Span of control
The span of control is the number of employees whom a manager is responsible
84
Wide span of control
- Gives subordinates the chance for more independence - More appropriate if labour costs are significant - reduce number of managers - Communication has to go through fewer layers
85
Narrow
- Allows for closer supervision of employees - More layers may be required - Helps more effective communication in small teams
86
Span of control depends on
- Personality & skill/ experience of manager - Size and complexity of the business - Whether the business is centralised or decentralised - The extent of use of clear objectives throughout a business
87
Chains of command
- The chain of command describes the lines of authority within a business
88
Levels of hierarchy
The number of layers of management or supervision in the organisation structure
89
Common types of organisational structure
Tall structure - Many layers in hierarchy and narrow spans of control Flat structure - Flat hierarchy, wide spans of control - Delegation encourages
90
Comments on tall structures
- Key features - many layers of hierarchy and narrow spans of control - Allows tighter control due to less delegation - More opportunities for promotion - Takes longer for communcation to pass through the layers - More layers = More staff = Higher costs
91
Comments on flat structures
- Key features - few layers of hierarchy and wide spans of control - Less direct control and more delegation - Fewer opportunities for promotion, but staff given greater responsibility - Vertical communication is improved - Fewer layers = less staff = lower costs
92
Changing the organisational structure
why change the structure - Growth of the business means a more formal structure is appropriate - Reduce costs - Reduce complexity - Employee motivation needs boosting - Key function improvements Challenges - Managers and employee resistance - Disruption and de-motivation = potential problems with staff retention - Costs of redundancies - Negative impacts on customer service quality
93
Delayering
- Removing layers of management from the hierarchy of the organisation
94
Benefits and drawbacks of delayering
- Reducing layers in the hierarchy - Lower labour costs - Faster decision making - Shorter communication paths - Stimulating employee innovation - Widening spans of control - Greater emphasis on teamworking and empowerment
95
Delegation
The assignment to others of authority for particular functions, tasks, and decisions
96
Advantages of delegation
- Reduce management stress and workload - Allows senior management to focus on key tasks - Subordinates are empowered and motivated - Better decisions and use of resources - Good methods of on the job training
97
Disadvantages with delegation
- Depends on quality and experience of subordinates - Harder in a small firm - May increase workload and stress of subordinates
98
Employee empowerment
Giving employees the power to do their job
99
Empowerment
- Linked with motivation and customer service - Employees need to feel that their actions count
100
Authority and organisational - Who makes the decisions
- Decision making is about authority - Should authority rest with senior management (centralised) or should it be delegated further down the hierarchy (decentralised)
101
Benefits of centralisation
- Easier to implement - Prevents other parts of the business becoming too independent - Easier to control and co-ordinate - Economies of scale and overhead savings easier to achieve - Quicker decision making
102
Disadvantages of centralisation
- More bureaucratic - Lack of authority down the hierarchy may reduce manager motivation - Lack of training and developing junior management - Customer service misses flexibility and speed of local decision making
103
Functional structure
The traditional organisation structure of a business has focused on the functions, departments and main activities of a business
104
Product based structures
Organisational structure based around the product portfolio of the company
105
Skills audit
- Skills audit is the process of assessing the skills and competencies of an organizations employees. Some of the benefits of conducting a skills audit include: - Identifying skills gaps and and determining training needs - Helping organisations plan for future skills needs - Enhancing employee retention and reducing turnover
