Program Overview

Lean Six Sigma: Methodology or Mindset?

Lean Six Sigma is often perceived merely as a process improvement methodology designed to enhance productivity while minimizing variation and waste. While this perspective holds some validity, it presents only a partial understanding of its true essence. Beyond being a structured methodology, Lean Six Sigma embodies a mindset that fosters continuous improvement, problem-solving, and data-driven decision-making. This mindset extends beyond operational efficiency, influencing organizational culture and leadership approaches. Therefore, rather than viewing Lean Six Sigma solely as a set of tools and techniques, it should be recognized as a comprehensive philosophy that drives sustainable improvements and innovation across various industries.

“Lean Six Sigma is about the mindset, not about the tools.”

Lean Six Sigma Mindset

Lean Six Sigma embodies a mindset centered on continuous improvement, emphasizing the necessity of adapting to the dynamic demands of both customers and the broader environment. Given that change is the only constant in life, the adoption of this methodology is not merely an enhancement but a fundamental requirement for organizations and individuals striving for operational excellence. By fostering a culture of continuous learning and process refinement, Lean Six Sigma enables businesses to remain competitive and responsive to evolving challenges. Therefore, integrating this mindset is not an optional practice but an essential approach to achieving sustainable success in an ever-changing world.

Mindset and Application

The practical application of a continuous improvement mindset within Lean Six Sigma is contingent upon the specific organizational context. Lean Six Sigma provides solutions to a wide range of challenges, both short-term and long-term. A distinction can be made between two types of problems: those that are readily identifiable, often referred to as "low-hanging fruit," and more complex challenges requiring a structured problem-solving approach. "Low-hanging fruit" pertains to evident customer concerns that can be addressed on a recurring, short-term basis. These issues are typically categorized as "ongoing initiatives," as they should be identified and resolved as part of routine operations. The resolution of such concerns is an integral component of daily continuous improvement efforts. Conversely, more intricate problems, where the root causes are initially unknown, necessitate a structured, project-based approach. These initiatives, often spanning a duration of approximately three to six months, involve rigorous problem-solving methodologies such as Six Sigma or A3 projects. To effectively implement continuous improvement within these project-based initiatives, organizations may benefit from structured interventions such as monthly reviews, bi-weekly workshops, or regular project meetings. In contrast, addressing low-hanging fruit can be facilitated through the use of improvement boards and short, frequent discussions, such as daily or bi-weekly huddles.

Toolset

These types of initiatives and methods to continuously improve and solve problems require the right attitude and mindset, but we can only apply them by using the tools we have at our disposal. Anyone reading Lean Six Sigma books will find a magnitude of tools. These range from more complex statistical tools such as a Design of Experiments (DOE) to qualitative tools such as brainstorming or fishbone diagrams. The tool you pick depends on what you want to change (the type of problem) and the situation you’re in (long-term project or ongoing initiative).

Tools, Methods and the Pitfall of Obfuscation

It is at this point that we encounter one of the pitfalls of Lean Six Sigma; focusing on the tools instead of the mindset. When I did my Black Belt course so many years ago, I remember having to memorize a myriad of tools, ranging from visualization tools to complex statistical tools, each accompanied by a variety of complicated abbreviations. And besides this plethora of tools, there were also a bunch of methods to memorize, each of which was related to a different set of tools that you could use. After all, a hammer by itself does not produce a chair; this requires a ‘method’ of carpentry. But hammers don’t belong solely to the carpenter’s arsenal of tools, as they’re also vital to the construction worker in his labors. The only thing that should be important to both the carpenter and the construction worker is that they deliver the product that the customer wants; the hammer is just a means to an end. The same applies to Lean Six Sigma’s tools.

A Mindset above all else

Studying the numerous tools and methodologies associated with Lean Six Sigma can be an overwhelming experience, often leading to difficulty in discerning the broader objective. This challenge underscores a fundamental principle: Lean Six Sigma is primarily a mindset rather than merely a collection of tools. The application of tools without the appropriate mindset is a key factor contributing to the failure of Lean Six Sigma initiatives. While individuals may acquire technical proficiency in these tools, an improper mindset often results in resistance to change, leading to a reversion to reactive problem-solving rather than addressing root causes to achieve sustainable improvements.
