Efficient quality management: How you can reduce your error rate

High error rates cost time and money. This realization is old and applies to all industries. Successful error management is therefore not a luxury, but an investment that pays off. However, the prerequisite for this is that such management is also known.

The work processes of modern Industry 4.0 and their possibilities are still far from being fully utilized everywhere. Particularly in the area of quality management, many companies are not yet exploiting the full potential of possibilities that did not even exist before digitalization.

This results in errors that would not actually be necessary if, for example, the use of certain tools was fully known, but unfortunately there is a lack of experience or knowledge.

Let’s take a closer look at how you can reduce your error rate: With practical steps and proven methods from quality management, a lot can be done. Read our blog to find out how you can make optimum use of resources and increase customer satisfaction – small changes can sometimes make a big difference.

Employee checks production processes to reduce error rates and optimize quality

The most important facts at a glance

  • Quality management includes elements such as quality planning, control, assurance and improvement and is based on standards such as the ISO 9000 series of standards to promote product quality and customer satisfaction.
  • Preventive approaches such as the Poka Yoke system for avoiding human and mechanical errors or FMEA risk management, which can be used to identify and prioritize potential product defects, are frequently used.
  • Error management is also familiar with methods such as lean production or TPM. They optimize company processes, increase efficiency and reduce the error rate if used correctly. It is important that the team is involved: Regular training, an effective communication culture and active participation on the part of the team ensure the success of error management methods.

The importance of quality management

What does quality management involve? Among other things, the term refers to measures for planning, controlling and improving processes in accordance with defined requirements. The primary objective is always to improve the quality of products or services. High-quality products and services increase customer satisfaction – and satisfied customers are more likely to return.

Quality management is based on a process-oriented approach: All activities within a company are understood as processes that can be monitored and optimized. The focus is therefore on the individual steps of production, not on the product itself. Successful management is system-oriented and makes decisions based on processes and facts. This is a basic prerequisite for profitable business. Quality management supports this way of working.

System-oriented management means that all human and material factors that can influence production quality and customer satisfaction are considered. They are all potential sources of error that need to be uncovered.

Errors, whether human or mechanical, lead to product defects that have a direct negative impact on customer satisfaction. Therefore, the elimination of defects is one of the top priorities of every company in terms of quality objectives.

Important elements of quality management

If you want to establish an effective quality management system in your company, you need a basic understanding of it. Let’s take a look at industrial production: Here, the fundamental pillars of quality management are as follows

  • Quality control planning: Sets targets, defines quality standards and establishes procedures to meet these standards.
  • Quality control: Includes inspections and tests during the production phases, i.e. ensures that flawless products leave production.
  • Quality assurance: Includes proactive measures to prevent errors, such as team training, process definitions, selection of suitable tools, inspection of products.
  • Quality improvement: Continuously examines data from ongoing production in order to re-evaluate processes and discover opportunities for improvement.

Standards and norms in quality management

The core element and legal framework of quality management is the standard. More precisely, compliance with the standards and norms specified in the ISO 9000 series of standards. This international standard contains all the central specifications and principles of quality management that we use today.

ISO 9001 certified – the seal of quality management

This standard provides companies with a framework for the development of quality management systems that contribute to improving product quality and customer satisfaction. The basic aim of this standard is that companies should organize themselves in such a way that they actually and reliably deliver the services they promise their customers. Among other things, this means that

  • processes are reliably organized,
  • all essential information is reliably documented,
  • processes and communication are designed to be comprehensible at all times,
  • promises, such as punctual deliveries, are also regularly kept.

Preventive measures to avoid errors

Preventing errors is one of the main objectives of quality management, if not the most important. This is because errors cost time and money and reduce the quality of products and services – which drives customers away. That is why successful quality management focuses on ways to reduce existing errors and prevent future errors from occurring in the first place.

Preventive measures help with a view to the future. Processes can be checked and designed to be error-proof, provided they are sufficiently analyzed. Today, there are a number of methods and tools that standardize the process and allow every company to quickly define suitable measures and implement them in their own company.

Poka Yoke – avoid unnecessary mistakes

One example of error prevention methods is the Poka Yoke principle. In simple terms, this Japanese word describes a method that avoids errors by making processes “foolproof”. Errors in the production line, for example, are avoided by designing the environment in such a way that process steps can easily be carried out correctly. Mechanisms that indicate errors immediately so that they can be corrected quickly are also part of this approach. Poka Yoke is therefore a preventative method that designs the work in such a way that errors do not occur in the first place.

The Poka Yoke system uses various devices and mechanisms that are designed to make errors in the production process more difficult or to prevent them completely. An effective poka-yoke system is characterized by the fact that it is easy to use and excludes errors in principle.

FMEA risk management

FMEA risk management is another important approach to error prevention. The FMEA method supports preventive quality assurance by systematically identifying and prioritizing the causes of errors and potential defects in the production process.

FMEA analysis is a structured process consisting of seven steps:

  • Planning and preparation
  • Structural analysis
  • Functional analysis
  • Error analysis
  • Risk analysis
  • Optimization
  • Documentation of the results

In FMEA, the risk priority number (RPN) is used to assess the risk of potential failures by multiplying the severity, probability of occurrence and difficulty of detection of failures.

Process optimization and increased efficiency

If you want to make fewer mistakes, you need optimally defined processes and efficient workflows. Analyses show where improvements can be made, where the error rate is high and where more efficient tools could speed up processes. Process optimization leads to an improvement in the quality of your production processes, a reduction in the costs of these processes and a reduction in the error rate.

That sounds complicated at first. However, optimized production processes are the guarantee for low error rates and therefore for the long-term success of the company.

Modern analysis tools bring data to light that make success visible in figures. Process indicators such as throughput time, error rate and productivity, for example, show which costs are incurred and where they can be reduced. The same applies to time management and personnel costs.

Total Productive Maintenance (TPM)

Total Productive Maintenance (TPM) is another holistic approach to improving quality and efficiency, mainly used in the field of production, such as plant and mechanical engineering. TPM aims to improve production tools through greater operator involvement. The aim is to minimize losses and waste, avoid defects as far as possible and keep machine downtimes to a minimum. Originally developed as a method for maintaining machinery, TPM is now a concept that applies to the entire company and its quality management.

The implementation of TPM comprises a combination of preventive and condition-based maintenance as well as continuous plant improvements according to a five-stage approach. TPM helps to reduce waste, lower maintenance costs, increase productivity and improve safety standards as well as employee motivation.

Employee participation and training

Even in the age of Industry 4.0 and big data, the success of a company still depends on the individual team members. They continue to play a decisive role in quality management. For example, companies rely on participation programs that set clear goals for employees and communicate them in a transparent manner. This demonstrably increases employee satisfaction – which not only helps the success of production, but also makes the company attractive as an employer. Appropriate training and general support for employees through participation programs lead to greater job satisfaction, which prevents job changes and possibly also attracts sought-after new specialists.
