Chapter 26: Lean Production and Quality Management

Introduction Lean production and quality management are crucial for businesses aiming to
remain competitive by improving efficiency and ensuring product quality. Lean production
focuses on minimizing waste while maintaining high quality, and quality management ensures
that products meet customer expectations.

1. Lean Production

Definition: Lean production is a systematic method for waste minimization without sacrificing
productivity. It involves streamlining operations to create more value for customers while using
fewer resources.

Key Lean Production Techniques:

 Simultaneous Engineering: This method develops new products by performing essential

tasks like design, market research, and costing concurrently rather than sequentially. This
approach reduces the time to market for new products.
 Cell Production: Instead of a single production line, the process is divided into self-
contained cells, each responsible for completing a whole unit of work. This method
increases worker motivation, enhances teamwork, and boosts productivity.
 Flexible Specialisms: Lean production requires flexible employment contracts, adaptable
machinery, and multi-skilled workers to quickly switch between product designs and
meet changing consumer demands.
 Simultaneous Engineering:
o Example: Imagine a car manufacturer like Toyota developing a new vehicle
model. In traditional production, the design team would finish their work before
the engineers begin their tasks. However, with simultaneous engineering, the
design, engineering, and market research teams work concurrently. As the
designers finalize the exterior look, the engineers are already planning the
mechanical aspects, and the marketing team is identifying target customers. This
approach shortens the development time, enabling the company to launch the car
faster than competitors.
 Cell Production:
o Example: Consider a furniture manufacturer producing chairs. Instead of having
one long assembly line where each worker only performs a single task (like
attaching legs or painting), the production is divided into cells. Each cell is
responsible for making an entire chair from start to finish. One cell might cut the
wood, assemble the parts, and apply the finish. This method increases the sense of
ownership and accountability among workers, leading to higher quality and faster
production.
 Flexible Specialisms:
o Example: Think about a clothing company that produces seasonal fashion items.
During the summer, they focus on producing swimsuits, and in winter, they
 switch to coats and jackets. Lean production here involves having flexible
machinery that can quickly be reprogrammed to produce different items and
workers who can easily adapt to new tasks. This flexibility allows the company to
respond quickly to changing fashion trends without large delays or excessive
costs.

2. Quality Management

Concept of Quality: Quality management ensures that a product meets or exceeds customer
expectations. It focuses on making products that are "fit for purpose," meaning they fulfill the
intended use reliably.

Quality Control vs. Quality Assurance:

 Quality Control: This traditional method involves inspecting products at the end of the
production process. However, this approach can be costly, potentially demotivating for
workers, and does not always prevent defective products from reaching the customer.
 Quality Assurance: This method focuses on setting quality standards at each stage of
production, emphasizing prevention over inspection. Workers are responsible for
ensuring their work meets these standards, fostering a culture of "getting it right the first
time."
 Quality Control:
o Example: In a food processing plant, quality control might involve inspecting the
final products before they are shipped to stores. Workers might check for defects,
like damaged packaging or incorrect labeling. However, if defects are found at
this stage, the company might have to discard the products, leading to waste and
higher costs.
 Quality Assurance:
o Example: Instead of just checking the final product, a bakery might implement
quality assurance by ensuring that every step of the bread-making process adheres
to strict standards. This includes checking the quality of flour as it arrives,
ensuring ovens are at the correct temperature, and monitoring the mixing and
kneading processes. By focusing on each stage, defects are caught early, reducing
the chances of producing defective loaves.

Total Quality Management (TQM): TQM is a comprehensive approach where all employees
contribute to quality improvement. It involves continuous improvement, with each worker being
responsible for quality at every stage of production. TQM aims to reduce defects and improve
overall efficiency by involving everyone in the organization.

 Example: A smartphone manufacturer adopts TQM by involving every department in the

quality process, from design to customer service. For instance, the design team might
 work closely with customer service to understand common complaints about previous
models. They then incorporate this feedback into the new design to avoid repeating past
mistakes. The production team ensures that each phone is tested multiple times during
assembly, and the customer service team follows up with buyers to gather feedback for
continuous improvement. This holistic approach reduces defects and improves customer
satisfaction.

Costs and Benefits of Quality Management:

 Costs: Implementing quality management systems requires investment in training, new

technology, and sometimes a shift in company culture. However, these costs are often
outweighed by the benefits.
 Benefits: Effective quality management can reduce waste, lower unit costs, increase
customer satisfaction, and ultimately improve the competitiveness of the business.
 Costs:
o Training: A company might need to invest in training its employees to
understand and implement new quality standards. For example, a hospital might
train its staff on new hygiene protocols to reduce infection rates, which involves
time and financial investment.
o Technology: Implementing a new quality management system might require
purchasing advanced machinery or software. For instance, a car manufacturer
might invest in robotic arms that can weld with precision to ensure every vehicle
meets safety standards.
 Benefits:
o Reduced Waste: A factory producing bottled beverages implements quality
management to reduce the number of bottles that are incorrectly filled or capped.
By improving the filling process, the factory reduces waste, saving money on raw
materials and increasing overall efficiency.
o Increased Customer Satisfaction: A hotel chain implements TQM by training
its staff to focus on customer feedback. They introduce a new system where
customer complaints are logged, analyzed, and addressed quickly. As a result,
customer satisfaction scores improve, leading to repeat business and positive
reviews.

Summary Points

 Lean production minimizes waste and improves efficiency, benefiting both businesses
and employees.
 Quality management ensures products meet customer expectations, with TQM involving
everyone in the organization in the pursuit of quality.

2. An objective of the company is to achieve ‘quality output at low costs’.

Evaluate the importance of the four factors listed in the case study in helping to
achieve this objective.

The four factors listed are:

1. Just-in-time Production:
o Importance: Just-in-time production reduces inventory costs by minimizing the
amount of stock held at any one time. This helps the company lower costs while
ensuring that production is closely aligned with demand. However, it requires a
reliable supply chain and precise coordination to prevent delays, which could
disrupt production.
2. Multiskilled and Flexible Workforce:
o Importance: A multiskilled workforce enables workers to switch between tasks
and machines, improving productivity and reducing downtime. Flexibility in labor
allocation helps Wheeler’s adapt to different production needs, which is crucial
for maintaining efficiency and lowering labor costs.
3. Use of Different Production Methods:
o Importance: By using both batch and flow production methods, Wheeler’s can
efficiently manage both specialized and high-volume products. This allows the
company to meet diverse customer demands while optimizing production costs.
Batch production allows customization, while flow production achieves
economies of scale.
4. Quality Assurance with Emphasis on Prevention:
o Importance: Emphasizing quality assurance and defect prevention ensures that
fewer resources are wasted on rework or scrap, thus reducing costs. A high
standard of quality also maintains customer satisfaction, which is critical for
sustaining business and reducing costs associated with customer complaints and
returns.

Conclusion: All four factors are crucial in achieving the dual objective of quality output at low
costs. Just-in-time production and a flexible workforce directly contribute to cost efficiency,
while different production methods and quality assurance maintain the balance between high-
quality output and cost control.

needs.

Cons:

1. Supply Chain Risks: The toy industry is often subject to seasonal demand fluctuations,
and any disruptions in the supply chain could lead to stockouts at critical times, such as
during the holiday season. This could result in lost sales and damage to customer
relationships.
2. Quality Control Issues: JIT may pressure suppliers to meet tight deadlines, potentially
leading to quality issues if suppliers cut corners to deliver on time. Poor-quality toys can
lead to returns, recalls, and reputational damage.
3. Implementation Challenges: Switching to JIT requires significant changes to existing
processes and systems, which could be difficult for a company like AVCO that is already
struggling to compete. The initial implementation phase might cause disruptions that the
company can ill afford.

Conclusion: While JIT could offer significant benefits to AVCO, the appropriateness of this
approach depends on the company’s ability to manage the associated risks, particularly regarding
supply chain reliability and quality control. If AVCO can establish strong supplier relationships
and ensure that their operations can handle the demands of JIT, it could be a viable strategy.
However, the risks should be carefully weighed against the potential benefits.
