As the business world continues to evolve and globalize, competition between companies continues to increase. To remain ahead of the competition, today’s corporate teams across industries must adopt methodologies like Lean Six Sigma to improve their operations and agility.
Often left to the manufacturing world, this methodology for continuous improvement and business process optimization can help organizations in virtually every industry.
With the increasing trend of employees leaving the workplace, organizations must revise and improve their processes and systems to fulfill increasing product or service demand. If they don’t do it, someone else will.
Companies strive for maximum efficiency and quality, yet the best solution may only sometimes involve technology or automatization.
Sometimes revising operations and processes can help attain and surpass desired results.
Even when adopting technology, you must ensure that your processes and systems are optimized and that your people can sustain the transformation.
What is Lean Six Sigma?
Lean Six Sigma (LSS) is a proven methodology that emphasizes streamlining and simplifying processes. The methodology also minimizes mistakes and simultaneously focuses on customer satisfaction.
The result is a company-wide mindset of improvement and optimized operations. This translates into reduced operational costs, improved business outcomes, and greater agility.
The Lean Six Sigma methodology approach marries two powerful philosophies: Lean’s philosophy to improve agility and Six Sigma’s focus on improving quality through defect reduction.
When employed together, these tactics create an unbeatable combination for optimizing productivity and bottom-line results.
Lean is a set of principles that focus on eliminating waste, streamlining the flow of activities, and improving efficiency.
Lean identifies eight types of waste:
- waiting time
- excess inventory
- underutilizing intellect (e.g., personnel capabilities, knowledge, and skills)
Defining Six Sigma
The Six Sigma methodology enables process optimization and defect elimination by targeting variations in performance. Drawing from statistical principles, the approach emphasizes measurement and monitoring to accurately evaluate process fluctuations and variability.
This way, businesses can eliminate waste or redundancies while increasing efficiency.
Certified Six Sigma professionals use the five-step DMAIC process to assess and improve overall business performance.
This financial evaluation and data analysis system is perfect for pinpointing any deficiencies in a company’s operations. It includes;
- defining the problem they wish to address,
- measuring its current condition (including identifying the root cause)
- analyzing it for solutions,
- improving any areas of concern
- and ultimately controlling them in order ensure successful long-term outcomes.
Six Sigma certifications are often pursued by manufacturing operations leaders. These certifications are often provided by professional educational organizations abiding by international certification standards.
These criteria include educational qualifications and job standards to acquire belt rankings similar to those in martial arts.
LaSalle Group believes that Lean and Six Sigma drive the best results when they work in tandem.
Combining Lean and Six Sigma
By unifying Lean principles and the Six Sigma methodology, you increase the speed and quality of results. It’s a holistic system that allows businesses to achieve greater efficiency, cost savings, quality assurance, and customer satisfaction, all while creating a better workplace culture.
Most organizations see LSS as a set of tools to improve processes and help achieve greater results.
They often lose sight of an incredible benefit: Lean Six Sigma focuses on providing value to the customer and engages everyone in the process.
Wouldn’t it be remarkable to enable 100% of your team to participate in driving better results and delivering customer satisfaction?
The Lean Six Sigma approach to problem-solving is popular among large companies, small businesses, and individual freelancers alike.
LSS is an all-encompassing system that doesn’t require complete overhauls or expensive investments — it simply calls for improvement in existing processes. Once you start to embed LSS in your way of working, it never ends.
Lean Six Sigma Belts
Lean Six Sigma can be applied to any organization, small or large, and in any sector of the economy. Although Lean Six Sigma is well-known in the manufacturing industry, not everyone knows about the methodology’s benefits or its belt rankings in the general business world.
