Abstract

Introduction of the Last Planner System helped to improve predictability and overall productivity in the construction industry. In manufacturing, the use of takt- time resulting in production to a set beat, has long been a center piece in leveling work flow and optimizing production lines. This paper will explore how we successfully merge the rigorous and more pre-determined structure of takt-time planning with the fluid, more interactive and responsive Last Planner System. The paper will use the Cathedral Hill Hospital Project as an example of takt-time planning in use and describe how the production team can work together with Last Planners to make sure that the structure and alignment from the takt-time plan also improve and simplify the Last Planner’s ability to plan their work successfully. We are especially interested in the dynamics around worker buy-in and the notion of manageable chunks’ of work to improve the ability for workers to plan successfully.
