Kaizen and its 3-Mu checkpoints

Question: What is Kaizen? What are the 3-Mus checkpoints of Kaizen activities? Explain how Kaizen helps in waste reduction and continuous improvement in TQM.

Kaizen

Kaizen (meaning literally 'continuous improvement') is a Japanese word for the philosophy that defines management's role in continuously encouraging and implementing small improvements involving everyone.

Improvements come at little or no expense, without costly equipment. It breaks complex processes into sub-processes and improves them. Example: changing a welding booth's colour from black to white improved visibility and weld quality.

3-Mus checkpoints of Kaizen activities

Kaizen checks every area of work for three problems: Muda (Waste), Muri (Strain) and Mura (Discrepancy). These are checked against eleven checkpoints: manpower, technique, method, time, facilities, jigs and tools, materials, production volume, inventory, place and way of thinking.

Reducing waste: common checkpoints

1. MAN: Waste of work force through poor training and development.
2. METHODS: Waste through non-value-adding tasks.
3. MACHINES: Unused, underused or badly maintained machinery.
4. MATERIALS: Stockpiling, warehousing and deterioration of goods.
5. MEASUREMENT: No measurement, so nobody knows if targets are arbitrary.
6. Work-in-progress: Quality is not built in, but depends on being inspected out.

How Kaizen gives continuous improvement

1. Continuous improvement rather than innovation: Innovation is a sudden big leap and fades. Kaizen builds step by step on existing strength.
2. Process-driven, not result-driven: When the process is controlled, results improve automatically. Effort is rewarded too.
3. Customer focus: Ishikawa's idea: "the next process is the customer". Never pass defective work down the line.
4. Standardisation: The SDCA cycle sets a standard, which becomes the base for the next improvement.
5. Right first time and Poka-Yoke: Mistake-proofing devices prevent errors at the source. The aim is zero defects.

Conclusion: Kaizen removes Muda, Muri and Mura through small daily improvements by everyone. It rewards effort, removes the need for inspection and breaks departmental barriers.

TQM, cost leadership and differentiation together

Question: Is it possible for the organisations to pursue both generic strategies of Cost Leadership and Differentiation simultaneously while implementing TQM? Justify giving examples.

Yes, it is possible. The book states that, contrary to achieving just one strategy of Porter's generic model, an organisation can achieve both cost leadership and differentiation simultaneously. Both may be needed for sustained competitive advantage.

Sources that make both possible

The literature names four sources: high quality, innovation, learning effects and economies of scale.

Justification

1. Mintzberg's view: Mintzberg offered an alternative to Porter. It includes "differentiation by quality" as a generic strategy. Others are image, design, price and support.
2. Flawless quality does both: Several writers say flawless quality, and the systems that produce it, are the main way to get low cost and differentiation together.
3. Link with cost leadership: Cost leadership comes from low cost of quality, high workforce productivity, a flat structure and short response times.
4. Link with differentiation: Differentiation comes from dedication to flawless quality and value for customers.
5. High quality with low cost: Cost of quality may be 20 to 30% of cost of goods sold. TQM firms have cut it by 90% or more. Some reached the zero defect stage.
6. Cross-functional systems: TQM uses horizontal structures, fewer management levels and cross-functional teams. This cuts cost and serves customers better.
7. Customer value strategy: Under TQM the focus is on the customer, not only on competitors. Delivering the best value retains old customers and wins new ones, which raises market share.

Examples

1. Japanese organisations: Many Japanese firms in consumer electronics and automobiles have used a quality strategy successfully.
2. Wal-Mart: Its low-cost culture gives it sustained competitive advantage as the world's largest discount retail store.
3. Honda: Honda made a more competitive car than General Motors by controlling cycle time and processes.

Conclusion: Historically, high quality meant high cost. TQM breaks this link. By removing the cost of poor quality, a firm becomes cheaper and better at the same time.

The seven quality improvement tools

Question: What are the seven quality improvement tools which form the basis for decisions and actions in an organisation? Explain each of them.

In SPC, numbers and information form the basis for decisions and actions. So a set of simple statistical tools evolved to collect, present and analyse quality data. These came from the methods of Walter Shewhart and W. Edwards Deming (1930s to 40s). Kaoru Ishikawa, head of JUSE, formalised them as the 7 QC tools.

1. Flowchart: Shows the order of activities in a process. Oval = start/end, box = action, diamond = decision point. It shows steps that affect quality. It is often the first step in Business Process Reengineering.
2. Histogram: A bar chart showing the distribution of a variable. Its shape and width show the nature of a quality problem. Example: students lined up by height.
3. Pareto Chart: Shows effects of different causes, arranged from most frequent to least frequent. It picks out the vital few from the trivial many and shows which problems to work on first. Named after Vilfredo Pareto, the Italian economist.
4. Cause and Effect Diagram: Also called the fishbone chart or Ishikawa diagram. Main causes branch off a core line; sub-causes branch off them. It shows where data should be collected.
5. Scatter Diagram: Shows the relationship between two variables. Example: does the common cold rise as temperature drops? Points close to a line mean a strong relation.
6. Run Chart: Data points plotted in time order and joined by a line. It shows trends over time, before and after a change.
7. Control Chart: A line chart with control limits at 3 standard deviations above and below the average. It is the core of SPC. It is based on Dr Walter Shewhart's studies of the 1930s.

A histogram gives a static picture of variation; a run chart or control chart shows dynamic performance over time.

Conclusion: These seven simple tools let everyone, from shop floor to management, collect, see and analyse quality data. So decisions are based on facts, not opinions.

Leadership in TQM implementation

Question: How does leadership fit into the TQM implementation process? Explain with the help of examples.

"Leadership is the fundamental factor in deciding how an organisation turns out to be."

Great organisations are never produced by accident; they are the product of great leadership. Leadership is needed at supervisory and managerial levels too, not just at the top.

Key elements of leadership in an enterprise

1. The future: The leader creates a shared mission and vision. Example: if the mission is to make the best common man's car at the lowest price, the vision could be the number of people owning that car in a certain year.
2. A theory or a philosophy: All actions come from the leader's theory. Example: McGregor's "Theory X" distrusts people; "Theory Y" trusts them. TQM gives a sound theory of management.
3. Defining current reality: Work with facts and data. Leaders should visit the workplace and use their five senses, not stay desk-bound.
4. Setting goals and making plans: Management runs through the PDCA cycle. Goals must be challenging but meant to be achieved, not manipulative "stretch targets".
5. Building teamwork: An organisation is a system of interdependent parts. Example: a buyer who "indigenises" a spare part to cut cost may cause more breakdowns in the plant.
6. Aligning and empowering people: Align people to the mission, the philosophy ("Quality first", "respect for people") and the way work is done.

Elements of leadership behaviour

1. Maturity: Balance between the courage to act and deep compassion for others.
2. Abundance mentality: The attitude that gives win/win solutions for everyone.
3. Learning and self-renewal: Great leaders are great learners, from reading, experience and their own people.
4. Compelling commitment: Humility and ownership of problems, together with energy and confidence.
5. Acknowledgement: Valuing people for what they are; commitment to them is unconditional.

As Feigenbaum said, quality is not a short-term, "instant-pudding" way to compete. Implementing TQM requires hands-on, continuous leadership.

Conclusion: Leaders give TQM its vision, theory, goals, teamwork and alignment. Without committed, learning leaders at every level, TQM cannot be implemented.

Safety management and its role in TQM

Question: What do you understand by safety management? Describe the role of safety management in TQM.

Safety management

"The first duty of business is to survive, and the guiding principle of business economics is not the maximization of profits, it is the avoidance of loss." (Peter Drucker)

An accident causes loss of the three Ps: People, Property and Process. Safety and Health Management deals with avoiding such accidents.

General concept

Accidents are caused by two factors: an unsafe act (due to an individual) and an unsafe condition such as a slippery floor or poor lighting (a management responsibility). So safety management is two-pronged: prevent unsafe acts and provide a safe workplace.

'Hazard' is something that has a potential for harm. 'Risk' is the likelihood of the harm happening, and the consequences in case it happens.

Job Safety Analysis (JSA): five steps

1. Selection of the task.
2. Breaking down the task into steps.
3. Identifying the hazards of each step.
4. Assessment of risk: to prioritise corrective action.
5. Recommendations: to eliminate the hazards.

Elements of a safety programme: the three E's

1. Engineering: Plan the programme using hazard identification and JSA.
2. Education: Train everyone, including contractors; use posters and signages.
3. Enforcement: Rewards, safety competitions and disciplinary action.

Role of safety management in TQM

1. People: TQM needs all people involved. Their performance depends on safety and health at work.
2. Process: An accident causes machine downtime and loss of production, so productivity and quality fall.
3. Customers: Customers are more aware of safety of products and services.
4. Business excellence: The Malcolm Baldrige criteria include employee well-being and satisfaction, covering health and safety.
5. Continuous improvement: A target of "zero" injury is a journey of continuous improvement, an essential element of TQM.

Safety styles: SWAMP (16%), NORM (77%) and World class (7%) of organisations. Management commitment makes the difference.

Conclusion: Safety management prevents unsafe acts and conditions. It protects people, processes and customers, so it directly supports TQM.
