Satish Narayanan was one of the key leaders that directed me when I was managing the productivity agenda for PepsiCo Jordan. Satish is a distinguished leader in the corporate world. As one of his team members I found him an intelligent creative visionary that balanced between challenging/motivating the team to achieve more, and coaching/understanding his reports and team members.

He always saw a potential in equipping all the talents in Jordan’s team to achieve our productivity targets and has built a pleasant relationship with all members from different levels when he led VSMs and LSS training. Satish was the initiator and main driver of the LSS agenda in PepsiCo Jordan. Personally, Satish taught me how to be patient yet dream big and his knowledge in LSS and other fields is inspiring

An incredibly talented individual and a perfect human. I was one of those lucky ones who got trained by Satish on Lean Sigma and got certified 30-day record completion of a PepsiCo Category Forecasting model. The project nature is highly complex & Big data management. Satish was instrumental in getting the maximum result in a short span of time.

His in-depth SME knowledge helped many people to get certified as such high-level recognition. I wish him all the success in his future endeavors.
