Contents Lean Construction Ireland Annual Book of Cases 2020 87 Terms & Concepts Weekly Work Plan (WWP) The commitment-level (will) planning step of LPS identifying the promised task completions agreed upon by the performers. The WWP is used to determine the success of the planning effort and to determine what factors limit performance. It is a more detailed level than the look-ahead and is the basis of measuring PPC. Weekly Work Planning The process by which the Last Planner establishes the plan for the coming period. Work Flow The movement of information and materials through networks of interdependent specialists. Work Structuring Designing the production system to determine who does what, when, where and how, usually by breaking work into pieces, where pieces will likely be different from one production unit to the next. The purpose of work structuring is to promote flow and optimise system throughput by focusing on handoffs and opportunities for moving smaller batches of work though the production system. Workable Backlog An activity or assignment that is ready to be performed, but is not assigned to be performed during the active week in the WWP. If the team agrees that performance of this activity will not hinder other work, then it can be placed on the list of Workable Backlog as part of the WWP. Completion or non- completion of these activities are not recorded or counted in calculation of PPC. Work In Process (WIP) The inventory between the start and end points of a production process. X-Matrix Used in Hoshin Planning, the X-Matrix is a template used in organisational improvement that concisely visualises on one page (A3) the alignment of an organisation’s True North, its Aspirations, its Strategies, its Tactics, and its Evidence.
