The success of a brand or a product is intricately tied to the quality it offers. When a product meets high standards of quality, customers are more likely to choose it over others. Therefore, prioritizing quality management is crucial for any business.

Losing a customer due to quality issues is something no business can afford. It's far more beneficial to continually work on enhancing processes and manufacturing, aiming for zero-defect manufacturing to ensure top-notch quality and customer satisfaction.

Zero-Defect Manufacturing

In zero-defect manufacturing, it is vital to instill a mindset among all employees that every product must be free of defects and that each person is accountable for performing their tasks accurately.

Renowned scholar Philip B. Crosby, in his book "Quality is Free," emphasized that product defects can lead to significant financial losses. The zero-defect approach focuses on enhancing the manufacturing process to eliminate product defects.

Shifting Perception: It is essential to cultivate a mindset that strives for perfection in every aspect of the manufacturing process.

Quality-Related Losses: Identifying and addressing potential losses stemming from poor product quality is crucial for sustained success.

Anticipating Challenges: Proactively identifying and addressing potential issues resulting from low product quality is essential for maintaining a competitive edge.

To illustrate, when a car's brakes malfunction, customers expect the service center to rectify the issue effectively. Similarly, by adhering to a zero-defect approach, you ensure that your customers receive products free of any defects, bridging the gap between your expectations for yourself and those of your customers.

Implementation of Zero-Defect manufacturing process

Defect prevention is preferred to correction

Preventing defects is more advantageous than correcting them later on. Identifying and addressing defects in the early stages is more efficient than dealing with them at a later stage, as it saves time and resources. For instance, if you notice that the brake shoe of your bike is not functioning properly, it's wise to replace it immediately rather than waiting for it to fail completely and potentially cause an accident.

Quality to meet customer requirement

The primary objective of a product should be to consistently meet and exceed customer expectations and requirements. For instance, when considering an ink pen, a local brand's ink pen performs reliably without any ink leakage, whereas a costly gold-plated ink pen may leave ink marks while writing. Despite its higher price, the gold-plated pen fails to deliver on customer requirements, making the local brand's pen the preferred choice.

Another example is CarboMedics, a company that specializes in manufacturing medical equipment, including artificial heart valves. By adopting a zero-defect approach in their manufacturing process, CarboMedics ensures that their products fit perfectly the first time, meeting the specific requirements of their customers within the medical industry.

Change in working behaviour

In order to implement a zero-defect management process, it is important for everyone, including top management, employees, and workers, to undergo a change in their working behavior. This may involve adopting new quality control measures, improving attention to detail, and enhancing overall work standards to ensure zero defects in the management process.

Quality check to be mandatory

It is essential that a thorough quality check is conducted at every stage of production to ensure that no product leaves the factory without being thoroughly inspected. The primary objective of the quality check is to identify any defects as early as possible and to take corrective action promptly.

In addition to formal quality checks, implementing a self-testing process is crucial. Furthermore, it is important for all team members to not only check their own work but also to review the work of their colleagues and provide guidance as needed to ensure that high standards are consistently met.

Skilling and training

Training and skill development are crucial for the workforce in your factory to ensure the smooth functioning of processes and minimize the possibility of errors. You can organize regular training sessions and display comprehensive training guides prominently on the walls throughout the factory. This approach will provide employees with easy access to reference materials, enabling them to clarify any uncertainties they may have.

In addition to traditional training methods, consider incorporating One Point Lessons into your training program. One Point Lessons are concise, focused training sessions lasting approximately 10-15 minutes, typically led by experienced team members. This practical approach allows workers to gain hands-on experience and better grasp the operational aspects of specific machinery and processes, contributing to enhanced overall understanding and proficiency.

Automation

The majority of errors are caused by humans rather than machines. Therefore, it is crucial to implement automation in order to minimize the occurrence of mistakes in processes.

Evaluation

To assess whether the zero defect manufacturing process is effectively implemented in your company, it's important to utilize various tools to gauge the efficiency of production, minimize wastage, and determine the overall improvement in product quality. Some of these tools include:

Total Productive maintenance (TPM)

Total Productive Maintenance (TPM) is a comprehensive approach used in production management to optimize the effectiveness of equipment. The main goals of TPM are to reduce cycle time, increase production output, and minimize defects. One of the key practices in TPM is the use of inspection cards, which are used to track the inspection status of machines and identify maintenance needs. Additionally, TPM forms are available to assist in organizing all relevant information, ensuring that maintenance activities are carried out efficiently and effectively.

Total Quality Management (TQM):

Total Quality Management (TQM) is a systematic approach to quality improvement that aims to ensure that the entire process of producing a product or delivering a service is carried out correctly the first time, thus minimizing the occurrence of any quality issues. TQM involves a continuous commitment to quality by all members of an organization and focuses on customer satisfaction, employee involvement, and process improvement.

Service Quality Measurement (SQM):

In the Service Quality Measurement (SQM) process, you can request customers to rate your product based on its reliability. Additionally, they can provide ratings based on their in-store or online shopping experience, as well as their interactions with customer care agents over the phone. When customers rate your product on these different parameters, you can gain insights into areas that may need improvement.

Six Sigma Quality (SSQ):

Six Sigma Quality (SSQ) is a methodology that focuses on minimizing defects and variations in processes to achieve a high level of quality. It involves a rigorous approach to identifying and eliminating causes of errors or defects in manufacturing and business processes. By implementing Six Sigma Quality, organizations can ensure that quality checks are integrated at every stage of production, leading to improved efficiency and customer satisfaction.

Poka Yoke

Poka Yoke is a technique used in manufacturing to prevent errors and mistakes. Originating from Japan, this method involves implementing processes that include safeguards to prevent errors from occurring. For example, workers may receive alerts through an alarm system before making a mistake, allowing them to take corrective action. This approach aims to improve quality and reduce defects in the production process.

Quality Measured in Terms of Money

Quality in manufacturing is often measured in terms of money. When a product has a defect, it can lead to additional expenses, as the product may need to be inspected, reworked with new materials, and require additional labor. Furthermore, customer satisfaction may be affected, resulting in further costs. For instance, in recent years, numerous cars were recalled globally due to various issues, with nearly 300,000 cars being recalled in 2019 because of airbag problems. These recalls affected major brands such as Maruti, Ford, and Hyundai. To maintain quality, companies have started implementing zero-defect tools in their manufacturing processes. Additionally, if suppliers fail to meet the standards of zero-defect manufacturing, companies may refuse to accept parts from them. The entire process of creating and delivering a product to the customer's door is crucial for maintaining quality.
