As we embark on this intellectual journey, it's imperative to remember that navigating the business landscape is often akin to setting sail on a tempestuous sea. In an environment riddled with variables, having a proficient navigator could mean the difference between sinking or sailing. One such navigator that has quite the reputation in the business world is the 'Six Sigma Consultant.'

Six Sigma, a set of tools and techniques developed by Motorola in 1986, is designed to improve processes by identifying and removing defects and minimizing variability in business processes. It's a philosophy that fosters an environment of continuous improvement and efficiency. The consultants, the shepherds of this philosophy, provide guidance on how to effectively implement Six Sigma in an organization. Yet, the path to engagement isn't always as straightforward and well defined as the theories they espouse. Here are five key insights I wish I had known before hiring a Six Sigma consultant.

• The Importance of Cultural Congruity:

  The implementation of Six Sigma is not merely a process modification; it's a cultural shift. Karl Marx once said, "The human being is in the most literal sense a political animal, not merely a gregarious animal, but an animal which can individuate itself only in the midst of society." Similarly, a Six Sigma consultant should not just be skilled but must also be able to merge with the existing cultural ethos of your organization. If the consultant's style is too alien or abrasive, it may lead to resistance, impeding the successful implementation of Six Sigma principles.

• The Weight of Experience:

  Theories and frameworks are essential, but the application of Six Sigma principles requires a deeper understanding that only comes with experience. While credentials like Black Belt or Master Black Belt are impressive, don't overlook the value of hands-on experience. A seasoned Six Sigma consultant, akin to a chess grandmaster, will be adept at foreseeing potential obstacles, planning moves ahead, and modifying strategies promptly, enhancing the chances of a successful project completion.

• The Necessity of Customization:

  Much like the Heisenberg's Uncertainty Principle in quantum mechanics, where it's impossible to measure simultaneously both the position and velocity of a microscopic particle with any degree of accuracy or certainty, applying a one-size-fits-all approach in Six Sigma can lead to uncertainty and inefficiency. Each organization is unique, with its own set of problems and processes. A consultant who can tailor the Six Sigma approach specifically for your organization, rather than rigidly adhering to a pre-defined plan, will yield the most effective results.

• The Cost of Consultation:

  Adam Smith's concept of 'invisible hand,' explains how individual self-interest and competition can lead to economic prosperity. However, in the realm of consultancy, this can also lead to inflated rates. Before hiring a Six Sigma consultant, it's vital to conduct a comprehensive cost-benefit analysis. The consultant's fees, coupled with the cost of potential downtime during process change, can be significant. Be sure the projected improvements in efficiency and cost-saving will outweigh these expenses.

• The Expectation of Ongoing Support:

  Implementing Six Sigma is not a sprint, but a marathon. It's not a one-time project, but a continuous commitment to improvement. A proficient consultant should provide ongoing support even after the initial project concludes, assisting with any amendments, reviews or audits. In the realm of business, as in biology, it's not the strongest that survive, but those most responsive to change.

In conclusion, employing a Six Sigma consultant can be a strategic move towards streamlined processes and enhanced profitability. However, as John C. Maxwell said, "A leader is one who knows the way, goes the way, and shows the way." Therefore, it's imperative to ensure your Six Sigma consultant not only knows the Six Sigma way but can effectively integrate it into the unique fabric of your organization, leading you smoothly through the tempestuous seas of business.
