Lean Construction Ireland Annual Book of Cases 2021 103 and performance indicators in plain view.This ensures that the status of the system can be understood at a glance by everyone involved and actions taken locally in support of system objectives. VUCA This stands for Volatile, Uncertain, Complex, Ambiguous, and it describes the situation of constant and unpredictable change that is now the norm in certain industries and areas of the business world. VUCA demands that we avoid traditional and outdated approaches to management, leadership, and day-to-day working. Waste The opposite of value, these are activities/processes that do not directly add/contribute value to customers, and that the customer would not be happy to pay for.The aim of Lean is to reduce and remove waste from processes. WasteWalks These are“GembaWalks”and are a form of direct observation and simply entail a planned visit to where work is being performed to observe what’s happening and to note the waste. It differs from gosee activities in that you are specifically looking for waste. WeeklyWork 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. WeeklyWork 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 theWWP. If the team agrees that performance of this activity will not hinder other work, then it can be placed on the list ofWorkable Backlog as part of theWWP.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 Part of the Hoshin Planning process, the X-Matrix is a template used in organisational improvement that concisely visualises on one page (A3) the alignment of an organisation’sTrue North, its Aspirations, its Strategies, itsTactics, and its Evidence. Glossary Editor’s Note This Glossary is compiled from various sources, including theWIT Glossary ofTerms & Concepts, the Lean Construction Institute (USA) Glossary, and the Lean Enterprise Institute Lexicon. It is recommended that plain language terms be used as much as possible.
