Six Sigma

Six Sigma is a rigorous and disciplined methodology that uses data and statistical analysis to measure and improve a company's operational performance by identifying and eliminating "defects" in manufacturing and service-related processes. Commonly defined as 3.4 defects per million opportunities, Six Sigma can be defined and understood at three distinct levels: metric, methodology and philosophy.

The Six Sigma Strategy

To achieve Six Sigma quality, a process must produce no more than 3.4 defects per million opportunities. An “opportunity” is defined as a chance for nonconformance, or not meeting the required specifications. This means we need to be nearly flawless in executing our key processes. Clients value consistent, predictable business processes that deliver world-class levels of quality. This is what MAC strives to produce through our Six Sigma process improvements.

Critical to Quality:

Attributes most important to the customer

Defect:
Failing to deliver what the customer wants

Process Capability:
What our process can deliver

Variation:
What the customer sees and feels

Stable Operations:
Ensuring consistent, predictable processes to improve what the customer sees and feels

Design for Six Sigma:
Designing to meet client needs and process capability

The “DMAIC” Methodology For Client Centric Approach

Define: What is important to the client

  • Client Surveys
  • Client Assessments

Measure: What Is The Frequency Of Defects? 

  • Process Mapping
  • Baseline Measurement

Analyze: Why Do Defects Occur?

  • Descriptive Statistics
  • Data Measurement
  • Hypothesis Testing

Improve: How Can We Improve The Overall Process? 

  • Design Of Experiments
  • Expert Brainstorming
  • Benchmarking

Control: How Can We Sustain The Improvement?

  • Measurement Feedback & Control
  • Assimilate process across verticals
