What is Six Sigma?

It was in 1987 when Six Sigma was beginning to be developed and introduced in the industry. Thus, Six Sigma can be traced back to the early 1980s at Motorola; this electronics manufacturing firm suffered from several quality issues. At this time, Motorola was struggling with a high level of new product failures within the consumption cycle, thus damaging customer relations and hindering production rates. The organizational leaders realized an optimistic ranging application method essential to elevate the company's quality and efficiency. Indeed, Six Sigma proved to be the answer, significantly improving the quality and efficiency of companies that embraced it.

Based on the previous study, Six Sigma was introduced by Bill Smith, often referred to as the ‘father of Six Sigma,’ and Mikel Harry. The Six Sigma methodology was developed by Bill Smith, a Motorola engineer, to solve Motorola’s vital problematic areas with quality. He favored the method of quantification of the quality and utilizing statistical tools to control and find ways of eradicating all the causes of variation. Mikel Harry, a Motorola engineer and later a very active Six Sigma consultant, was also one of the essential contributors to the development of Six Sigma as an organized process.

Mikel Harry, a Motorola engineer and later a very active Six Sigma consultant, was one of the essential contributors to the development of Six Sigma as an organized process. His engagements involved defining the process, designing the training methodology, and supporting institutions adopting Six Sigma. His dedication and expertise have significantly shaped the Six Sigma we know today, and we owe much respect to his contributions.

Six Sigma is a business management strategy developed to enhance quality and decrease the variation in business processes and their results while reducing defective products and services. Six Sigma" refers to the statistical concept where a process operates with a defect rate of fewer than 3.4 defects per million opportunities. The goal is to achieve near-perfect quality by focusing on the following fundamental principles:

1. Define: This step states the customer's scope, objectives, and expectations. The customer's needs are assessed, and probable enhancement goals are determined.
2. Measure: Gather information about the existing processes to build the current state snapshot. In this phase, the key performance indicators are determined, and the process performance is evaluated to analyze the current problems and deviations.
3. Analyze: The principal cause of defects must be determined by analyzing the company's acquired data. This phase involves employing statistical tools and procedures to identify the root causes of quality issues.
4. Improve: Propose appropriate interventions for the causes envisaged during the analysis stage. This phase is mainly concerned with designing experiments and evaluating modifications to increase reliability and decrease abnormality.
5. Control: The improved processes must be monitored and controlled to sustain these results. This phase is focused on implementing procedures and controls that can enhance the sustainment of improvements and eradicate the return of defects.

The Six Sigma program smoothly unveiled at Motorola ensured the enhanced quality of products and, at the same time, made working operations more effective. The elimination/minimization of the defects/variability extended customer satisfaction, lower costs arising from rework/scrap, and increased Motorola's productivity. Thus, the positive results of Six Sigma at Motorola motivated other organizations to adopt it into their business. Therefore, Six Sigma’s influence did not stop with Motorola: it contributed to developing other methodologies and quality improvement frameworks. Its principles and practices have been widely adopted. They are now recognized as part of the basis of modern concepts and approaches to quality management and continuous improvement.

As Motorola’s implementation of Six Sigma achieved remarkable results, it became widely recognized as one of the major frameworks for improving organizational performance. Since then, Six Sigma has become popular in manufacturing industries and later spread to the healthcare, finance, and sectors that provide services. Six Sigma has thus been accepted as a business strategy tool by many organizations to enhance and realize operational efficiency. It is necessary to state that Six Sigma management originated in Motorola and was motivated by quality problems and controlling the process. The methodology invented by Bill Smith and Mikel Harry has gone a long way to become one of the fundamental approaches to managing quality and improvement, bringing tangible values to organizations worldwide.

Six Sigma's heart is the DMAIC framework—Define, Measure, Analyze, Improve, and Control. This systematic, data-driven approach helps organizations understand their processes, identify inefficiencies, and implement lasting improvements. The results speak for themselves. Motorola saved billions of dollars, and General Electric, another early adopter, reported savings of over $300 million in the first year alone.

The IT industry is largely fast-paced and ever-changing; managing the industry’s diverse and complex issues needs a tighter problem-solving method. Six Sigma can solve these challenges as a tool that can help optimize the software development life cycles, decrease the number of bugs in made programs, and advance project management. For example, a large IT company, which constantly faced problems with software development inconsistencies, started applying Six Sigma methodologies and got outstanding results. With the help of implementing the DMAIC method, the main reasons for the delays and defects were defined. Through the auditing and optimization of data, they cut the bug rates in half and minimized the time-to-market of new software releases. Furthermore, it can be realized that Six Sigma contributed to centralizing project management techniques, which are more likely to increase reliability regarding the results they bring. Encouraging the IT teams to look for the elimination of defects, Six Sigma’s documented and structured methodology promotes a culture of ongoing improvement. Consequently, the firm's efficiency increased, and customer satisfaction was higher due to delivering high-quality software on time. The survey insists that IT workers using Six Sigma see improvements in their project performance, higher efficiency, and more defined methodology in solving technical problems, confirming Six Sigma's strong standing as an essential tool in the IT field.
