Lean Six Sigma Process Improvement Support

ICF International possesses unparalleled credentials for providing Lean and Six Sigma support in both the private and public sectors.



Today most organizations are faced with developing and delivering a myriad of services, programs, or products that require complex enterprise-wide activities or process changes—with the usual objectives of increasing quality, reducing production time, managing risk, and minimizing the cost of delivery. ICF’s seasoned Lean Six Sigma Black Belt facilitators and implementers assist clients in achieving significant, tangible top- and bottom-line results. Applying value-added Lean and Six Sigma methodologies promotes a continuous process improvement environment designed to fulfill customer expectations for increasing efficiency, productivity, and profitability.

ICF’s comprehensive approach combines Lean and Six Sigma tools with a proven process to ingrain continuous process improvement into an organization’s culture and leadership practices, creating an organizational model with responsive decision making, flexibility, and innovation. ICF tailors its approach to meet individual client needs by identifying, assessing, and addressing issues related to people, practices, processes, and technology to create sustainable change.

What can Lean and Six Sigma methodologies do for your company?

  • Create a powerful connection from strategic priorities to operational improvements

  • Help facilitate a company’s transformation to align its corporate culture, processes, and capabilities

  • Increase efficiency in all areas of manufacturing and production

  • Decrease "re-work," which is the frequency of products or processes that have to be re-accomplished to develop a finished product

Progressive Lean Six Sigma Training™ Model

Like today’s common Lean Six Sigma course curricula, ICF employs a phased approach. But unlike those models that follow the DMAIC (define, measure, analyze, improve, control) project model completion sequence, ICF presents students with a less menacing, more orderly and logical approach, based on adult learning models, with project time between phases—increasing their likelihood of achieving mastery and ingraining principals into an organization’s culture. This phased approach is built on the fundamental implementation of Lean practices before progressing with more difficult six sigma deployments.

The four phases of the ICF Progressive Lean Six Sigma Training Model™ are:

Lean Practitioner

In alignment with our operating philosophy, ICF believes that process improvement training should begin with a strong introduction to the principles of a Lean Enterprise. In addition to training in flow, value, and waste, this training includes basic graphical analytical techniques and an introduction to the DMAIC framework. The toolkit at this level is relatively simple, but powerful, and does not require a specialized foundation in other subjects.

Understanding Variation – LSS Green Belt

In this Week II training session, ICF focuses on understanding processes, adding the basic statistical concepts of variation and central tendency. Introduction to the use of confidence intervals provides a simple, but analytical way, for the student to become a more powerful user of data collection and analysis. The core concepts taught during this phase are variation, probability, standard distribution models, standard error of the mean, control charts, and process capability.

Reducing Variation – LSS Black Belt Week I

During the third one-week session, students build on the confidence interval concept to develop the idea of statistical significance. Teaching focuses on tools which provide students powerful root cause analysis and prediction abilities, which is the key to success on more difficult projects. This session’s primary focus is on Hypothesis Testing, Analysis of Variance (ANOVA), regression and correlation, and Measurement Systems Analysis.

Optimizing Processes – LSS Black Belt Week II

The fourth-week module expands on the concepts of regression and ANOVA (analysis of variance) to include multivariate analysis. Beginning with an introduction to multiple linear regression and multilevel ANOVA, ICF progresses the student through designed experiments and advanced regression techniques.
