In December 2015, Crown Cab teamed up with the University of North Carolina at Charlotte where every employee attended the Yellow Belt Lean Six Sigma (LSS) course.  Crown Cab realized that its workflow was not well defined, and did not have adequate visibility into the processes  and work in progress. Similarly, documentation related to the drivers, vehicles, and the clients required a faster and more accurate filing and retrieval mechanism. Improving the workflow and documentation related tasks was important to grow and become the preferred service provider, hence two DMADV LSS projects were formulated.

LSS is a well-recognized quality management methodology. LSS projects follow two project methodologies called the DMAIC and DMADV continuous improvement cycles, which have roots in the Deming's Plan-Do-Check-Act Cycle. DMADV was used for the Workflow and Documentation Management System Design projects at Crown Cab.

Under the consultant Prof. Ertunga Ozelkan, two teams worked on the two projects. I was the coordinator between them and Crown Cab for all the data requirements, communications and training.

These projects established standard, efficient and scalable management systems at Crown Cab. Improved systems have helped to address the customer needs faster and accurately. Potential liability issues, costs due to errors and excessive handling have reduced. Crown Cab has more flexibility to grow and support its constraining operations.

We decided to present and share the success of our projects at the Engineering Lean & Six Sigma Conference 2016 by Institute of Industrial and Systems Engineers by designing a poster, creating a paper, and delivering a presentation as a speaker. We received 2nd award for our poster. Our presentation was well appreciated. Feedback: 4.2/5


The Lean Six Sigma projects started with Yellow Belt Course, continued with two projects at Crown Cab, and concluded with Awarad winning Poster, Paper, and Presentation at the Engineering Lean & Six Sigma Conference 2016 by Institute of Industrial and Systems Engineers.
