About Us


About Quantum Associates

Quantum Associates was founded in 1999 by Willie Carter. After spending over 25 years working for various industrial firms in operations and quality management roles Willie decided to establish his own process improvement consulting firm to leverage his operations and quality experience to help small to medium-sized industrial and service firms use process improvement methodologies  do more with less.

Our approach draws on the disciplines of Lean Management, Six Sigma Quality, and Constraint Management to help client organizations minimize their costs and accelerate their cycle time enabling them to do more with less.

Although we have worked with large companies our primary focus is on assisting medium-size companies (100-999 employees) to accelerate adding value to their products or services enabling them to improve gross margins and efficiency. We do this by building common ground, forming strong relationships with your people, and paying attention to detail in developing process improvements. Our process improvement consultants are dedicated professionals who are truly experienced in continuous process improvement utilizing lean management principles, six sigma and  the theory of constraints in both the manufacturing and service sectors.

How We Work

Preparing your team for process improvement.

Client Team

We conduct an assessment of your critical business processes to determine which combination of the process improvement methodologies will deliver the best results for you. During the assessment we listen to and engage your staff in dialogue, suspend judgment, explore assumptions and build common ground in an effort to gather the data to support our findings as well as establish buy-in . Our assessment will describe in detail the steps you need to take to meet your improvement objective (cycle time reduction, increased capacity,  quality improvement, improved collaboration, etc.)

After our assessment we will help you implement the business process improvement recommendations we proposed if you so choose. These recommendations may be rooted in lean methodology, six sigma, the theory of constraints or ISO 9001. Once the implementation phase is complete we offer sustainability services to help protect your process improvement investment.

Our process management consultants pride themselves in building strong relationships with your people cultivating them to help you meet the challenges of improving your organization. Our goal is to engage your employees to create buy-in. When your people are engaged in the transformation, satisfaction, performance, and profits increase.

We sweat the details in teaching your people how to use lean process improvement tools, six sigma process improvement tools, and process analysis to develop and execute improvements to your processes and to help you become self sufficient in the continuous improvement transformation. We focus on the details when developing improvements to your processes because the little things does matter and can make a difference in process integrity.

Only a few companies achieve sustainable results by permanently transforming themselves. Many companies practice Lean or Six Sigma process improvement, but they never truly internalize it as part of their DNA. Our brand of process improvement has proven successful in  manufacturing and service companies in helping them implement and sustain their refined/redesigned processes long after we are gone.
