GTLS: GAS TO LIQUID SYSTEMS® OneChart™ Culture Drives Synergy Ideas and Attainment 25 Hello Jill, I wanted to say a big thanks to you, Camille & Parvesh for yesterday’s shout-out. This really has been a great example of a OneChart approach with many teams involved. Whilst it was really nice for me to get the mention personally, there are many others within HAX & HIN that have contributed to get us to where we are now. One final push to get the casings to Germany (error free) and then I think we can really celebrate ☺ That said, thanks to all for the recognition & to David for his guidance on maintaining our objectives with this project. I always think it is nice to know that we are making a difference & with the Rugby World Cup & Olympics eminent in Paris it is great to see these metro lines taking shape. A small piece of the bigger picture… One Chart | Thank You! Hi Robin, Since we will finish the 6 Sigma training tomorrow, I would like to share my great appreciation to the teacher Named Khubaib. He is a great teacher, and I have learned a lot from him. He helped me figure out a lot of concepts which is pretty helpful for my work in the near future. I was impressed with his expertise and humble character. Great teacher. @Catalano, Robin also thank you, Great Arrangement. Have a great day. 6 Sigma Training | Emerging Leaders Hi Jill – I hope you are well, and I am glad the APAC visit went well with the team. Regarding the below request for a procurement slide for Amers, Europe & China regions. I am working with my regional procurement directors (Taylor, Calum & Liu Yan) to put this together early next week and share with you, Earl, Fred & Sherry. I have a regular cadence process in place monitoring these KPI’s, so the data is available. FYI – we also have a H2 integration plan (update attached) to make the overall procurement governance process consistent across the combined organization. In addition, I thought I would share how we are tracking on synergy, as of today: The team continue to make great progress and the collaboration is really the best I have seen at this stage of an integration process. Awesome…. Awesome Collaboration Hi Jill, Good to be in touch with you. I am Procurement Director for Europe, working closely with Colin, Fred, David and the wider regional team. Further to recent discussions with Colin, please see attached update on EU procurement performance. In summary, we’re tracking well against Howden FY23 AOP plan, rapid negotiation program exceeded expectations, and engagement has been excellent throughout integration of our supply chain teams. Please let me know if you have any questions or would like additional info. Thanks Team Work | AOP“This really has been a great example of a OneChart approach with many teams involved!” “I would like to share my great appreciation to Named.
