For the best results in careers such as healthcare, manufacturing, technology, service industries, and pharmaceutical companies, you must learn Six Sigma<\/a>, Lean, or Lean Six Sigma. Such processes are integral to business performance, quality of products, employee morale, and decreasing the variation process.<\/p>\n\n\n\n

Organizations lean toward strategies or processes that positively impact their operations. Learning these agile project management methodologies<\/a> can therefore land you a better position or a new job. This guide will help you decide whether Lean, Six Sigma, or some combination is the best process for a business to implement. <\/p>\n\n\n\n

What Is Lean?<\/h2>\n\n\n\n

Lean is a set of management practices that aims to improve efficiency and effectiveness by eliminating waste. Now a standard business methodology, this approach started as a revolutionary manufacturing process in the 1950s. At that time, the main Lean principles were respect for people and continuous improvement. <\/p>\n\n\n\n

According to Toyota, the seven kinds of waste in Lean manufacturing are inventory, waiting for motion over-processing, overproduction, defects, and transport.<\/p>\n\n\n\n

Lean also has roots in software development, where it helped optimize the software development life cycle<\/a> of Agile methodology. It creates value for the customer by optimizing a company’s resources, effort, and energy. Use the Lean methodology to identify the root cause of waste, reduce waste, deliver value, and improve the production process.  <\/p>\n\n\n\n

In this more recent incarnation, the fundamental Lean principles are value, flow, perfection, pull, and value stream. These principles are essential in reducing backlog when responding to customer requirements.<\/p>\n\n\n\n

What Is Six Sigma?<\/h2>\n\n\n\n

Six Sigma is also a set of tools and techniques that organizations use to improve business processes. It uses statistical data to eliminate defects and waste. This data-driven process works with six standard deviations between the mean and the closest specification limit. <\/p>\n\n\n\n

Six Sigma projects focus on implementing a measurement-based strategy to improve processes and reduce variation. To improve overall quality, it defines, measures, analyzes, improves, and controls processes falling below the specification guideline. <\/p>\n\n\n\n

Six Sigma has a hierarchy of certifications ascending from White Belt, to Yellow Belt, to Green Belt, and finally to Black Belt and Master Black Belt. Someone with the Six Sigma certificate in Master Black Belt can become a project manager<\/a> who consults on projects and offers strategic guidance to organizations.<\/p>\n\n\n\n

Lean vs Six Sigma: The Most Important Differences and Similarities<\/h2>\n\n\n\n

There is a vigorous ongoing debate about which of the two methods is better for streamlining business processes and eliminating waste. The main aim of business owners, after all, is to improve their ability to meet customer’s expectations. <\/p>\n\n\n\n

Both methods can easily eliminate waste and improve efficiency, but they do so in different ways. The differences and similarities in theoretical and practical aspects can help you select the best tool. Below are the main points to consider.<\/p>\n\n\n\n

Different Approaches<\/h3>\n\n\n\n

Lean looks to maximize value for the customer with the smallest number of resources, whereas Six Sigma aims to achieve high customer satisfaction by minimizing costs. <\/p>\n\n\n\n

Different Definitions of Waste <\/h3>\n\n\n\n

Six Sigma regards waste as a result of variation within a process, whereas Lean defines it as a process or activity that has no benefit to the customer.<\/p>\n\n\n\n

Different Leadership<\/h3>\n\n\n\n

Six Sigma is highly recommended for organizations that are highly structured and use a hierarchical model of leadership. Lean is more flexible and can be used in an autonomous organization to enhance collaboration. <\/p>\n\n\n\n

Different Functionality<\/h3>\n\n\n\n

Lean practices are most effective where maximizing customer value is paramount, as it is in software development. By contrast, Six Sigma works better in more complex environments, where decreasing variability and risk is key. These include engineering, manufacturing, sales and marketing, and customer service. <\/p>\n\n\n\n

Similar Histories<\/h3>\n\n\n\n

Lean and Six Sigma both had their starts in a complex manufacturing environment. As more and more businesses have adopted these tools, however, the objectives and goals of Lean and Six Sigma have begun to diverge.<\/p>\n\n\n\n

Similar Focus on Eliminating Defects and Waste<\/h3>\n\n\n\n

Both of these problem-solving processes seek to eliminate waste and defects<\/a>. Lean and Six Sigma can contribute to the general improvement of any business process.<\/p>\n\n\n\n

Similar Attention to Quality and Efficiency<\/h3>\n\n\n\n

They both can improve quality and efficiency by controlling costs, eliminating waste, and creating flow in the production process.<\/p>\n\n\n\n

Similar Emphasis on Customer Satisfaction<\/h3>\n\n\n\n

They both help in augmenting the quality of a product, which in turn helps to satisfy the customer. Businesses can use either of these tools to foster brand loyalty.<\/p>\n\n\n\n

The Lean vs Six Sigma debate is prevalent in the business world. The two systems are integral to eliminating waste and creating efficiency. However, they take different approaches to achieving the same goal. The following pros and cons will help you gain a better understanding of the processes and decide which is more suitable for your business.<\/p>\n\n\n\n
