What is 6σ DMAIC?

Process Maturity versus Six Sigma DMAIC Methodology
Process Maturity versus Six Sigma DMAIC Methodology
  • DMAIC’ is an acronym for “Define, Measure, Analyse, Improve, Control” This is the high level process or ‘roadmap’ used in Six Sigma improvement projects
  • The DMAIC methodology is a very powerful and effective methodology for improving existing products, services and processes to ‘Six Sigma’ level
    (For new products, services and processes see DFSS section)
  • Six Sigma (6σ) derives it’s name from it’s statistical performance target, which equates to 99.99966% good (or just 3.4 PPM defects)
  • Six Sigma achieves these incredible quality levels by:
  • Focussing on customer alignment of functions, features and processes
  • On establishing clear linkages to customer goals, variation from the goals is identified
  • Causes are identified, prioritised and eliminated and/or controlled
  • The result is virtually defect free parts, products, services and processes
  • Six Sigma DMAIC is a rigorous, ‘heavyweight’ process, requiring a high level of training, coaching and support to become proficient
  • Six Sigma practitioners are generally known as ‘Green Belts’ and ‘Black Belts’ .  They are coached by ‘Master Black Belts’ and supported by management ‘Champions’.
  • The personal development and subsequent career progression of Six Sigma practitioners is usually linked to becoming ‘certified’ at each level. Certification is dependant on having met a set of stringent, pre-defined criteria, including: education, experience, and proof of results through deploying the Six Sigma methodology and tools

Why we get results

  • We have substantial experience in training, coaching and deploying Six Sigma DMAIC
  • We can help you specify the best approach for your business (see Diagnostics for more details), or simply provide whatever consultancy, training and coaching or development you require
  • We’re practical and pragmatic - our focus is always on getting results (we’re practitioners - not just trainers!)
  • We tailor our services and approach to meet your needs (please see methodology deployment requirements diagram below)

There are three main Methodology Deployment options

There are three main Methodology Deployment options

There are three basic levels to deploy any methodology:

  • At a basic level a methodology can be used to solve a specific problem
  • Methodologies can also be deployed strategically to resolve strategic issues across the business.  Generally, this involves developing capability within the business to achieve this
  • Often, businesses decide to apply a uniform approach to business improvement across their entire business.  This, ‘total immersion’ approach, involves developing a ‘critical mass’ of capability within the company, with support structures to ensure that it is self-sustaining
  • We can help you, whatever deployment model you choose - please contact us to discuss your requirements

Capability Development

The level of capability development is an important factor in Strategic and ‘Total Immersion’ deployments

Stages of Capability Development: Training; doing supported by coaching; Community infra-structure development

Stages of Capability Development: Training; doing supported by coaching; Community infra-structure development
  • Training provides knowledge, but real understanding is only developed by doing
  • We offer a range of coaching services, to guide capability development and ensure that results are achieved.
  • Beyond having people that can do, you’ll need your own, sustainable, support structure to ensure the continued growth and success of your capability - we’ll help you create, or develop, your infra-structure to achieve this

Training, Coaching & Support

Besides full deployments, we also offer the individual components, to support and supplement existing programmes:

  • Six Sigma training: bespoke and ‘off-the-shelf’ Six Sigma DMAIC courses available:
  • Awareness
  • Champion
  • Green Belt
  • Black Belt
  • Master Black Belt, including 'train the trainer'
  • For more general information about training please click [link to Training page]
  • Six Sigma coaching: 
  • A range bespoke of support options to ensure that both personal capability and business results are achieved.  These range from providing a full-time support team to remote support options, as appropriate
  • Coaching is especially important for Six Sigma, as it is a ‘heavy-weight’  methodology  and can be abstract for anyone not familiar with statistical analysis.  It is therefore essential to safeguard your investment in training by ensuring that the trainees have adequate support during their early projects
  • For more general information about coaching please click [link to Coaching page]
  • Accreditation (certification) of Six Sigma professionals requires that they have proven their skills and understanding by successfully delivering projects using the methodology
  • We provide certification at all levels
  • When you have sufficient internal capability, we can also design, develop and install your own corporate certification process, ensuring that the capability you're developing continues to meet the real needs of your business.
  • Six Sigma community infra-structure: Bespoke services to design, develop and install appropriate capability support and development infra-structure

Imagine a future with your key metrics at 'world class' levels…
