Six Sigma
Stop the same defects from coming back
Six Sigma gives your team a structured way to define a quality problem, measure it, find the real root cause and put controls in place so it stays fixed.
The business problem
Rejections and rework keep returning. Each time, someone fixes the symptom, and a few weeks later it happens again. Customers notice inconsistent quality, and rework quietly consumes capacity and margin.
Who it suits
Quality and operations leaders, engineers and cross-functional teams facing recurring defects, high variation or customer complaints about quality.
Outcomes we work towards
- Fewer defects, rejections and rework hours
- Less variation in key product or process characteristics
- Decisions based on data rather than opinion
- Controls that keep the problem from returning
Actual results depend on your starting point, data and conditions.
Our approach
DMAIC, explained plainly
- D
Define
Agree the problem, the customer impact and the project goal.
- M
Measure
Establish a reliable baseline from real data.
- A
Analyse
Use root cause analysis and simple statistics to find what drives the problem.
- I
Improve
Test changes on a small scale and confirm they work.
- C
Control
Put a control plan, SPC and review routines in place so the gain lasts.
Indicative deliverables
- A defined problem statement and project charter
- A measured baseline
- Root cause analysis
- Tested improvements
- A control plan with monitoring (SPC where it fits)
- Process capability assessment where specifications apply
Confirmed for each engagement after a discussion. We do not publish fixed fees or durations.
Your team's involvement
A project sponsor, a project leader and team with time for the project, and access to process and quality data.
Delivery
Online, at your premises, or a mix. Projects can run alongside Green Belt or Black Belt training, so your people are certified on real work. Explore Certification Programmes →
Questions
Do our people need statistics training first?
No. We teach the methods the project needs as the project goes along.
How is this linked to belt certification?
Teams can combine a live project with White, Yellow, Green or Black Belt training. See Training for programme details.
What data do we need?
Whatever data you already record on the problem. If there is little, measuring it properly becomes the first step.
How long does a project take?
It depends on the problem and your data. We agree the timeline after the first discussion.
Which defect keeps coming back?
