“Excellence is the unlimited ability to improve the quality of what you have to offer.” –Rick Pitino
Defining Six Sigma
The model was proposed by a scientist who worked at Motorola in 1986. The term Six Sigma consists of a set of quality-control tools that companies can use to remove faults and improve processes to help boost profits.
Six Sigma process is a management philosophy whose main focus is on statistical improvements to a business process and prefers qualitative measurements of success over qualitative. This is based on the Greek symbol “sigma” which is a statistical term for measuring deviation from the process mean or target.
Six-Sigma has grown into a more general business-management philosophy, which is focused on meeting customer requirements, customer satisfaction, improving customer retention, and constantly improving business products and services.
Anyone can obtain Six-Sigma certification, which solidify and verify their professional skills. Six sigma certificates are awarded through a belt system similar to karate training.

Principles of Six-Sigma
The concept of Six Sigma methodology has a simple goal i.e. deliver near-perfect goods and services for business revolution and customer satisfaction. It has five key principles.
1. Focus on the customer:
A business needs to understand its customers, their requirements, and what is needed to make them long term advocates of the good or service. This requires maintaining the quality standard as defined by the customer or market demands. Basically the primary goal is to satisfy the customer.
2. Finding the problem:
Collect and analyze the data to discover specific problem area that requires to be assessed and transformed. Have clearly defined goals before data collection, including defining the data, reason for data collection, insight anticipated and accuracy of measurements, and establishing a standardized data collection system.
3. Removing the defects:
Once the problem is identified, make changes to the process to eradicate variation, thus removing defects.
Leader’s Tip
Foster a data-driven culture by emphasizing the importance of accurate measurement, analysis and evidence-based decision making.
4. Continuing the process:
Six Sigma process have a great impact on an organization, and the team has to be capable in the principles and methodologies used. So dedicated training and knowledge are required to reduce the risk of project or revamp failures and ensure that the process is performed positively.
5. Flexible and responsive ecosystem:
The people and departments involved should be flexible enough to adapt the change with ease, and to facilitate this, processes should be structured for quick and flawless implementation. Ultimately, the businesses that have an eye fixed on the data, inspects the bottom line at times and adjusts its processes where necessary and thus can gain a competitive edge.

What are Six Sigma methodologies?
There are two main six-sigma methodologies which are DMAIC and DMADV. Let us understand them in detail.
- DMAIC is a data-driven process used to develop existing products or services for better customer satisfaction. It stands for: Define, Measure, Analyze, Improve, Control. DMAIC is useful in the manufacturing of a good or delivery of a service.
- DMADV is a part of the Design for Six Sigma (DFSS) process used to design or revamp different process of good manufacturing or service delivery. It stands for: Define, Measure, Analyze, Design, Validate. DMADV is engaged when already existing processes do not meet customer satisfaction level, even after optimization.
The two methodologies are used in different business scenarios, and professional seeking to master these methods and application scenarios should do online certificate program taught by industry experts.
Leader’s Tip
