Six Sigma seeks to improve the quality output of processes by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes. It uses a set of quality management methods, mainly empirical, statistical methods, and creates a special infrastructure of people within the organization ("Champions", "Black Belts", "Green Belts", "Yellow Belts", etc.) who are experts in these methods. Each Six Sigma project carried out within an organization follows a defined sequence of steps and has specific goals, like increase productivity, increase efficiency, reduce pollution, reduce cost, increase customer satisfaction, increase profits and become more competitive. Sigma is the designation for the standard deviation, and a process capability of six standard deviations equals 3,4 defect per million opportunities. That is an ambitious goal! It requires continuous improvement and focus on understanding variation to gain control of production.

Six Sigma projects follow a project methodology inspired by Deming's Plan-Do-Check-Act Cycle. It includes 5 phases and bear the acronym DMAIC. DMAIC is used for projects aimed at improving an existing business process.

  • Define the system, the voice of the customer and their requirements, and the project goals, specifically.
  • Measure key aspects of the current process and collect relevant data; calculate the 'as-is' Process Capability.
  • Analyse the data to investigate and verify cause-and-effect relationships. Determine what the relationships are, and attempt to ensure that all factors have been considered. Seek out root cause of the defect under investigation.
  • Improve or optimize the current process based upon data analysis using techniques such as design of experiments (DOE), Components of variation (CoV), poka yoke or mistake proofing, and standard work to create a new, future state process. Set up pilot runs to establish process capability.
  • Control the future state process to ensure that any deviations from the target are corrected before they result in defects. Implement control systems such as statistical process control - SPC, production boards, visual workplaces, and continuously monitor the process.

Process control

Control process variation with SPC
statistical process control
Statistical Process Control, SPC, has many applications. Use it for predictive maintenance, quality control, decide process capability, robustness and effect of changes, etc. See Statistical Process Control video.


Increase your competitivness
production efficiency
Do you want 10 improvement tips? It includes advices about energy efficiency, production efficiency, quality improvement and productivity increase. Find out how to increase your production efficiency.


Consider error, then conclude
measurement error
Use Measurement System Analysis - MSA to decide measurement error. The medium you measure and the surroundings can influence the measurement. Check video about measurement error.


Use OEE to increase productivity
OEE (Overall Equipment Effectiveness) is a widely used productivity indicator, revealing losses and enabling us to improve. The available production time is crucial. More about this in the video Lean Tech has made about OEE.

Time management

Plan, act, measure and adjust
Time Management
Set a goal, create a strategy, take action and measure. This article includes a video about time management showing you how a mindmap, an activity plan, and easy time registration can help you measure, plan and improve.

  • value stream mapping"I was very impressed with Sissel's Lean Six Sigma knowledge. She makes it easy to identify improvements and create results"
    - Daryl Powell, Lean Manager, Kongsberg Maritime SubseaValue stream mapping
  • Lean engineering"Sissel has worked as part of Cambis project team for two of our projects. Her main focus has been on process design, engineering and procurement. Sissel has proven herself as a competent and committed employee. She has been an important contributor to make good progress in the projects she has worked with. At the same time she is accurate and has good quality of the work she performs."
    - Eivind Willoch, Project Manager, Cambi AS lean engineering
  • benchmarking"We are very happy with the work carried out. We was not very clear what the order was, but with your background and expertise the outcome was what we were looking for and a document we will benefit from in the future"
    - Roger Søråsdekkan, Site Leader at Allnex, Norwaybenchmarking
  • monitoring program"We hired Lean Tech to develop monitoring program for air emission. The monitoring program should satisfy requirements from the Norwegian Environment Agency including sampling frequency to ensure representative samples, uncertainty estimates, calculations and preparation of reporting templates, etc. The assignment was delivered with the correct content at the right time. Recommended." monitoring program
    - Kjell Even Misfjord, SHE manager at Allnex, Norway
