Contents Lean Construction Ireland Annual Book of Cases 2020 Terms & Concepts 84 is scheduled to be accomplished such as building design, completion of foundations, erection of exterior walls, building dry-in. A phase can be either a time period or a group of activities leading to the accomplishment of a defined goal/ milestone. Phase Plan A plan for executing a specific phase of a project using a pull technique to determine hand-offs. It is prepared by the team actually responsible for doing the work through conversation. Work is planned at the request/demand of a downstream customer. Plan Reliability The extent to which a plan is an accurate forecast of future events - it is measured by PPC. Planning The act of conversation that leads to well-coordinated action. Plus/Delta Review A continuous improvement discussion performed at the end of a meeting, project or event used to evaluate the session or activity. Two questions are asked and discussed. Plus: What produced value during the session? Delta: What could we change to improve the process or outcome? Poka-Yoke A Japanese term for mistake-proofing method or device developed by Shigeo Shingo that is used to prevent an error or defect from happening or being passed on to the next operation. Personal Protective Equipment (PPE) Integral to health and safety, this is the equipment worn to minimise exposure to serious workplace injuries and illnesses. Process Mapping A flowchart identifying all the activities, operations, steps, and work times for a process. Promise The action taken by a performer to commit to a customer to take some action to produce a mutually understood result, for example CoS, by a definite time in the future. Pull A method of advancing work when the next-in-line customer is ready to use it. A request/demand from the customer signals that the work is needed and it is pulled from the performer. Pull releases work when the system is ready to use it. Push Push an order from a central authority based on a schedule; advancing work based on central schedule. Releasing materials, information, or directives possibly according to a plan but irrespective of whether or not the downstream process is ready to process them. Quality Quality denotes an excellence in goods and services, especially to the degree they conform to requirements and satisfy customers. Quality Assignment Assignment that meets quality criteria for release to the customer process. The quality criteria are: (1) definition; (2) soundness; (3) sequence; (4) size; and (5) learning. Reason for Variance Factors that prevented an assignment from being completed as promised, used by the team to promote learning concerning the failure of the planning system to produce predictable workflow. By assigning a category of variance to each uncompleted task, a team is able to identify those areas of recurring failure that require additional reflection and analysis. Reliable Promise A promise made by a performer only after self-assuring that the promisor: (1) is competent or has access to the competence (both skill and wherewithal); (2) has estimated the amount of time the task will take; (3) has blocked all time needed to perform; (4) is freely committing and is not privately doubting ability to achieve the outcome; and (5) is prepared to accept any upset that may result from failure to deliver as promised. Request The action taken by a customer to ask a performer to take some action to produce a mutually understood result (CoS) by a definite time in the future. Right First Time (RFT) This concept involves ensuring that all activities/processes are carried out in the right manner the first time and every time. A quality management concept that defect prevention is more advantageous and cost effective than defect detection and associated rework. Root Cause Analysis Integral to Lean tools and techniques, and the essence of problem solving, this is a systematic method of analysing possible causes to determine the root cause of a problem. SCAMPER The SCAMPER technique is based very simply on the idea that what is new is actually a modification of existing old things around us. It is a creative thinking and problem solving technique developed to address targeted questions that help solve problems or ignite creativity during brainstorming meetings. The name SCAMPER is acronym for seven techniques: (S) substitute, (C) combine, (A) adapt, (M) modify, (P) put to another use, (E) eliminate, and (R) reverse.
