Contents Lean Construction Ireland Annual Book of Cases 2020 39 Case 10 Company Overview Mercury mercuryeng.com Overview & Background to the Lean Initiative Lean Initiative Undertaken – Lean Thinking, Tools, Techniques Jason Toomey Author Mercury began its Lean journey in 2014 with a great deal of energy and enthusiasm. Through our Yellow and Green belt programmes, many Lean projects have been undertaken and successfully implemented across all of Mercury’s business units in Europe. Like most organisations that are on their Lean journey, Mercury hit a state of homeostasis after a couple of years of success and lost some of its original momentum. In the last year, Mercury has refocused its efforts, and, by following the Plan, Do, Check, Act (PDCA) continuous improve- ment cycle has set up a governance structure to manage its Lean implementation plan and roadmap. The Mercury senior management have been actively involved in communicating our Lean philosophy across the organisation. We have re-established our Lean training program, with ten members of staff gaining Green Belt accreditation and one gaining Black Belt accreditation. The Lean initiative discussed in this case study examines the modular wiring system design and installation on a large-scale project in Ireland. The objective of this project was to reduce the time taken to produce Modular Wiring 2D drawings and reduce waste on-site utilising Lean Principles. The DMAIC methodology was used for this initiative, with several Lean tools utilised, including: Gemba Walks; Brainstorming; Current State Mapping; and Cause and Effect Diagrams. Collaboration and communication also played a significant part in the success of this initiative. Multiple cross-functional teams collaborating together is required to produce the end result of a modular wiring system designed, manufactured, and delivered to site. This includes the Site Engineering Team, BIM Modellers, CAD Techni- cians, Modular Wiring System Specialists, Lighting Control System Specialists, Project Design Consultants, and Electrical Distribution Board Manufacturers.
