The Rybnik Eng Center was reactivated at the beginning of 2008. One of the objectives of this new center is to develop the lean spirit and to directly apply it to the new center. Two years have now passed and these 2 papers give the opportunity to review the current status and to reflect on the lessons learned so far on our lean journey. The 2 papers are structured around people, processes and tools. The first paper focuses on the people, the second one on the processes and the tools. Some great progress has been made in the different areas of application including: - Processes: Some key engineering processes in Testing, CAD, CAE and prototype shop were thoroughly investigated and improved. Especially the quality of the outputs and significant reductions in lead times have been achieved. - Tools and Technologies: Tenneco worked on both aspects, the soft and hard tools. Soft tools are covering visual management which allows a better alignment.

After having successfully implemented lean manufacturing in the 1990ies and lean engineering since 2004, Tenneco Europe decided to expand Lean to their administrative organizations in October 2009. The implementation approach was directly derived from lean engineering [1], [2], [3], [4], [5], [6]. After having defined a vision and a road map, a lean steering committee, composed of senior managers and a lean coordinator, identified and supported the first areas for implementation of lean in their transactional processes. It was decided to challenge the organization by selecting some critical cross functional processes.

After having successfully implemented lean manufacturing in the 1990ies and lean engineering since 2004, Tenneco Europe expanded lean to its administrative organizations in October 2009. The implementation approach was directly derived from lean engineering previously implemented in Tenneco Europe as this was considered closer to administration processes than manufacturing processes were. A first SAE paper on lean transactional was presented in 2011. This paper covered a vision, a road map and a process to roll out the lean Spirit in the Administrative world. This paper and the papers listed in the reference list provide in detail the lean tools and principles used in lean transactional and engineering. This new paper is focussed on some concrete applications where the lean mindset has been implemented mainly by the finance team supported by sales, project management, marketing, manufacturing and engineering.

Tenneco first implemented the lean transactional process ten years ago. One of the key success factors was to ensure that the lean system was sustained within an organization as part of a philosophy of continuous improvement. This has probably been the most challenging part of implementing lean in Tenneco. During the early years of implementation, lean was managed as a top down approach which consisted of: identifying executing and tracking lean projects by the management, a small number of additional people and lean experts. This approach had the advantage of building up critical mass and helped to instill a lean change culture in a reasonable timeframe. But the Tenneco experience showed that even if early results were encouraging, the implementation was not consistent enough to sustain a mindset of continuous improvement. This top down approach needed to be reinforced by a much stronger bottom up approach which consisted of group leaders acting as change agents.
