- Websites can crash and go down resulting in lost sales
- High setup costs to establish online services
Material Management
The use, storage and delivery of materials to ensure the right amount of inputs are available when required in the operations system
Why do we need material management strategies
- Production ceases if materials aren't available
- Inferior inputs result in inferior outputs
- If quantity is too low demand can't be met
- If quantity is too high there are additional storage costs
Costs of storing inventory
- Potential wastage
- Damages can occur
- High storing costs
4 Material Management Stratagies
- Forecasting
- Master Production Scheduling
- Material Requirement Planning
- Just in Time
Forecasting
Relies on data from the past and present as well as analysis of trends to attempt to determine future events
Why use forecasting
- The business knows the amount of materials needed to meet customer demand
- Not overbuy materials and deal with high storage costs
Qualitative Forecasting
Subjective and gathers info that is based on the opinions of people
Quantitative Forecasting
Makes use of numerical data such as sales from a previous period
Strengths of Forecasting
- Ensures businesses maintain appropriate inventory on hand without overproducing goods and services
- Ensures businesses have enough stock to meet customer demand
Weaknesses of Forecasting
- Unforeseen events may occur, making forecasted date useless
- Forecasting is inaccurate as it is just a guess
The production plan and what it consists of
A production plan that outlines the activities undertaken to create G&S using resources. Includes Master Production Schedule and Material Requirement Planning.
Master Production Scheduling
A plan that details what to be produce, in what quantities, how and when. Planning above the businesses productive capacity will result in the plan not being met.
Material Requirement Planning
Producing an itemised list of all materials involved in production to meet the specified orders.
Strengths of a Production Plan
- Prevents a business from overproducing as too much inventory leads to storage costs
- Prevents a business from under producing, leading to missed sales
- Is flexible and can be changed to fit future production and new products.
Weaknesses of a Production Plan
- Information must be accurate or else errors will occur
- High cost to set up for both training and software
- Once production begins it can be hard to interrupt the process
Just-In-Time
A material management strategy that ensures the right amount of materials and other inputs arrive just as they are needed in the operation process
Strengths of Just in Time
- Reduces costs involved with storage
- Less of the businesses finances are held in stock, better liquidity
- Reduce risk of wastage occuring in storage
Weaknesses of Just in Time
- Suppliers must be reliable, a supplier failing to deliver can hold up production
- Increasing delivery costs as orders are arriving in smaller quantities
- Costly and time consuming to establish
Quality
The degree of excellence of a good or service and its fitness for its stated purpose
How does quality improve a businesses competitiveness
- More consistent, reliable and durable products
- Reduced defects and waste
- Reduces production costs and lowers prices
How will businesses manage quality
- Minimising waste and defects
- Strictly conform to set standards
- Reduce variance in final products
Three Quality Management Strategies
- Quality Control
- Quality Assurance
- Total Quality Management
Quality Control
The use of inspections at various points in the production process to check for any problems or defects.
What type of approach is Quality Control
Reactive, as it detects faults after the error occurred
Check and Reject Technique for Quality Control
- Establish Internal Standards
- Inspect output at regular intervals
- Compare output against standard
- Take corrective action when necessary
Comparison of Quality Control and Quality Assurance
Similarities
- Both improve quality
- Both establish standards
Differences
- QC is not certified, QA is certified
- QC checks the output, QA checks the processes
Weaknesses of Quality Control
- Inspections occur at random intervals so defects can still slip through
- It is reactive, therefor wastage will occur due to more resources needed to fix defects or throwing out defects
Quality Assurance
The quality of an organisation's procedures is endorsed by an external agency
What type of approach is Quality Assurance
Proactive, as it is process oriented and doesn't let defects occur
Systems to ensure Quality assurance
- Process checklists
- Audits
- Developing Standards
Types of endorsements a business can receive regarding quality
- Energy ratings
- International Organisation for Standardisation
Strengths of Quality Assurance
- Waste is reduced, more efficient use of resources
- Higher quality leads to higher sales
- Better customer trust
Weaknesses of Quality Assurance
- Expensive to ensure systems comply with standards
- Employees that maintain standards have a lot of stress and pressure
- Time consuming to apply for endorsements
Total Quality Management
An ongoing, business wide commitment to excellence that is applied to every aspect of the businesses operations
What type of approach is total quality management
Proactive as it prevents quality issues before they occur
4 Approaches for a business to achieve TQM
- Quality Assurance and Control
- Employee Empowerment
- Continuous Improvement
- Customer Focus
Employee Empowerment
Development of quality circles to discuss ways to improve quality of products, they then present their discussions to managers to improve business performance
Continuous Improvement
The belief no process is every perfect and that things can always be improved by benchmarking against the worlds best practice techniques.
Customer Focus
Attempts to improve quality by viewing products and process through a customer perspective. Employees must only provide customers with the highest quality
Strengths of TQM
- Reduces costs and reduces defects, improving efficiency
- Improved cost competitiveness and quality along with higher customer satisfaction allows the business to be more effective
Weaknesses of TQM
- Costly and time consuming
- Employees may resist change as they need to change their thinking and attitude
- Staff needs to be retrained
Strengths of Quality Control
- Improves effectiveness as better quality will lead to higher sales
- Enhanced business reputation relative to competitors, leading to better marketshare
Comparison of Quality Control and Total Quality Management
Similarities
- Both improve quality
- Both are ongoing
Differences
- QC is internal only, TQM is internal and external
- QC is product based, TQM is more broad
Comparison of Total Quality Management and Quality Assurance
Similarities
- Both improve quality
- Both use external standard
Differences
- QA is certified, TQM is not certified
- QA process focused, TQM focuses on customers aswell
Waste Minimisation
A process involving the reduction of the amount of unwanted or unusable resources produced by a business in an attempt to improve efficiency and effectiveness of operations
Reduce
Creating less waste by stopping waste generation at its source
Reduces links to efficiency and effectiveness
- Decreases costs associated with waste removal and loss of products which improve efficiency
- Lower cost of production improves sales and effectiveness
Ways to reduce waste
- Using Just in time to prevent waste from storing inventory
- Using a proactive quality control strategy to prevent defects before they occur
- Using technology to reduce human error and defects
Reuse
Taking older or unwanted items, usually thrown away and finding a new purpose for them
Reuse links to efficiency and effectiveness
- Reusing items reduces waste associated with discarding items
- Reusing can also generate a second revenue stream for businesses
Recycle
Changing discarded materials into new products in order to avoid using more natural and new resources
Recycle links to efficiency and effectiveness
- Recycled materials are cheaper, leading to lower production costs, improving efficiency
- Recycled materials help the environment and improve CSR, increasing customers and improving sales through more effectiveness
Ways to use Recycling
- Purchase new inputs made up of recycled materials
- Purchase input that can be recycled
- Inventing new ways to recycle different items
- Avoid buying materials that are difficult to recycle
Lean Management
An approach to operations management that attempts to improve efficiency and effectiveness by eliminating waste and improving quality, this is done by removing all unnecessary process which do not add to customer value
How does Lean Management Increase efficiency and effectiveness
- Reduces Waste
- Increases speed of production
- Lowers costs
- Improves Quality
Seven wastes a business should work towards eliminating (TIMWOOD)
- Reduce excess transport
- Avoid excess inventory
- Avoid excess motion
- Eliminate waiting times
- Avoid overprocessing
- Avoid overproducing
- Reduce defects
Four Principles of Lean Management
- Pull
- One Piece Flow
- Takt
- Zero Defects
Pull
Customers pull the amount of outputs produced as customer demand dictates the rate at which products are delivered, this reduces waste as the business will only produce products that will be sold
One Piece Flow
Eliminating waiting or idle time by focusing on one part of production at a time and removing unnecessary and wasteful activities, more efficient use of time and better quality as each process is done to a high standard
Takt
the rate of production needed to meet customer demand, it establishes a consistent and smooth workflow to meet consumer demand
Zero Defects
Striving for perfection by identifying errors as they occur and not accepting defects, this reduces waste levels, improving efficiency and improving quality
Lean Managements Link to Efficiency and Effectiveness
- Eliminating waste reduces cost and increases profit
- Better quality leads to higher customer satisfaction and better sales
- Reducing waste results in a more efficient use of resources
Strengths of Lean Management
- Increased worker productivity
- Increased customer satisfaction
- Reduces uncertainty in the businesses production
Weaknesses of Lean Management
- Requires committed and experienced employees
- Constant focus on improvement can stress out employees worsening motivation
- Employees may resent a change to lean
