In the problem solving and solution design world, there is a myriad of approaches and tools that are at the disposal of practitioners. At times, there have been objections that an approach takes too long or the expected results have not been achieved. Multiple factors could contribute to this outcome, but one that in our experience has been a major factor is when practitioners default to an approach that they are most familiar, instead of determining the approach that makes the most sense.

This presentation focuses on several popular approaches to problem-solving and design: Lean, DMAIC, DMADV, and Design Thinking. The goal of this presentation is to provide a high-level description of each approach, express similarities and uniqueness of each, and offer key selection criteria. The presentation will also showcase the use of a transformed QFD, a traditional tool used in the DMADV approach, as a way to help with the decision making.

QFD is a process for ensuring that client needs drive the future state functionality of a solution. It helps in organizing client requirements at all levels of the design, quantifying the requirements and comparing them on critical criteria. QFD has shown value in providing a structure to the design process while providing rigor that the solution meets the initial requirements, and documenting the decisions throughout the process. In this presentation, we will show how to use certain components of a QFD (and its benefits) to both differentiate and facilitate the transition between the problem solving/design approaches.

Conference Chair's Message 

Joel Smith

Continuous Improvement is not just something a Lean Six Sigma (LSS) practitioner leads their organization in practicing, but is also a core competency of their professional makeup. That is why more and more innovative and leading companies are looking for leaders that use the LSS way of thinking in everything they do within their organization.

In this era of data science and machine learning, the ability to connect the dots for end to end solutions across the boundaries of people, process and systems is the key to success. This year’s conference is focused on making sure we are “continuing” our journey as practitioners. Whatever your level of experience, you will learn new concepts, new perspectives and network with the best in the industry.
