JEL Consultancy has successfully deployed world-class performance improvement services in leading industries across Europe. We support all types of organisations across multiple sectors and disciplines to achieve world class performance improvements in terms of quality, cost reduction and volume increases. JEL Consultancy began in 2003 when senior managers responsible for developing and applying Lean practice in Toyota Motor manufacturing UK created hands on consultancy to deliver extraordinary results to ordinary companies within a sustainable culture of Continual Improvement. Through a hands on, down to earth and simple approach we supply the right expert for your needs. Our specialists guide your teams to install the right tools and techniques to achieve the desired results but most importantly they drive the behaviour change by leading. Since then, JEL has grown to service many industries, helping numerous organisations including Aisin, Delphi, Syncreon, Royal Mail and Bentley Motors and many more to evolve into more profitable, efficient businesses. With each new client comes a need to evolve and adapt performance-improving practices to suit the individual nature of everyone we work with. ‘Most managers will only manage but Leaders will Lead.’ This is a testament to the background of our senior management who actually developed many of the tools and techniques other companies now deliver. We firmly believe the ability to evolve our techniques to suit your operating environment using only Toyota trained Consultants sets us apart from our competitors and makes us unique in the market. JEL are an experienced team of Toyota former employees, each specialist gaining extensive experience being trained by a Japanese sensai in Toyota sites in the UK and Japan. ● Toyota trained ● Proven exemplary track records ● Bottom line delivery specialists For over 8 years we have delivered results such as: ● Increasing throughput of engines by 23% in 16 weeks!– Automotive ● £1,000,000 Inventory reductions through Level scheduling and Hiejunka – Aerospace ● New Product Introduction £600,000 cost avoidance Rail ● £4,000,000 Procurement Lean Value stream training – cost saving in the supply chain –Automotive ● Increase throughput of Powder Coating Paint Facility 85% within 4 weeks Case Study A/006 – Light Manufacturing JEL introduce a full Lean Production System to Waste Baler manufacturer The Performance Indicators speak for themselves !

There were problems with sharing tools, machines, cranes and this combined with the inherent high levels of waste in the process and quality concerns resulted in a loss of over £400 per unit. We approached the task taking fresh look at the layout and created a flow line with 8 Stations balanced to Takt, introduced a Wireless Andon System which empowered the operator to stop the line for any quality defect or problem. By removing the strip process from the area it established a clean assembly process improving the quality of the product. Versatility of the team was improved through the need to develop all members, which lead to improved morale. Previously the rigid layout meant each transmission had to be overhauled in a certain cell the flexible Lean Layout meant each station could work each type. As a result of the above changes and the change in approach fostered by the revitalised team the output increased from 7 transmissions per week to 25 per week without increasing labour costs Lean Tools Used: Wireless Andon – Call system to aid problem solving Takt Time - Create a theoretical pace Yamazumi – Effectively balance line Standard In Process stock – Create a Full Work System 5s – Bespoke wheeled shadow boards Photo New resin flooring to improve safety and 5s Visual Scheduling – For effective planning and sequencing Capacity Analysis for Test booths Kanban – Visual Pull system for Customer order Lean Culture Change Tools Used: Production Plan V Actual Performance Lean Leadership Behaviours Practical Problem Solving Kamishibai for sustainment of change. “Quote” “With the introduction of the Andoncall system our productivity and quality performance were significantly improved, we knew we could do things better but by reducing the hours it took to overhaul the gearbox from 33 to 18 hours seemed impossible but JEL took us through every step of the process with their unique hands on approach” Ranesh Gupta Production Control Manager For help with Productivity and performance contact: www.JEL-LEAN.co.uk Case Study S/003 – Service Sector The Royal Mail asked JEL to introduce Kamishibai into their Mail Sorting Depots in the UK and Ireland to support the sustainment of change. The Royal Mail through their own in house Lean improvement teams had made great strides introducing the lean foundation tools. They had installed Visual factory, 5’s’ and a basic TPM system at Operator level in multiple pilot areas. The problem they faced was a common one we have encountered , how to ensure the process changes made are maintained “Once the Focus has gone, how do you maintain the change?, Why is it when we go back the standards have dropped, it is so frustrating!” Kamishibai literally means "paper drama", it is a form of story telling. that originated in Japanese Buddhist temples in the 12th century A Kamishibai board is used as a visual control for performing tasks within a manufacturing process. A series of cards are placed on a board and selected at random or according to schedule by supervisors and managers of the area. JEL introduced a 3 Tier Kamishibai process, this created the perfect foundation as all 3 levels of the organisation accepted an element of responsibility to sustain their efforts. Team Leaders drove their daily activity around the Kamishibai system. Managers would also carry out process confirmation checks to ensure the standards are being achieved. The built in CCAR sheet created a list of issues which the Manager has responsibility to close out, the actions for these close out was part of the Senior Management level review as they too carry out Kamishibai tasks daily. Their main function is ensuring the process is followed and showing they care about the standards, and a Go, look, see activity each day demonstrated this commitment. Lean Tools Used: Kamishibai Standardised Work Visual Factory TPM 5s Practical Problem Solving Lean Culture Change Tools Used: Lean Leadership Behaviours – Go See - understand Practical Problem Solving Kamishibai - for sustaining the changes Built in Escalation QC Tools 5Why “Quote” “After engaging JEL to support our Lean Roll Out they showed us how powerful and effective Kamishibai is as a tool for sustaining the process and the benefits of linking 3 tiers together with a common purpose” Group Maintenance Manager For help with Productivity and performance contact: www.JEL-LEAN.co.uk Case Study R/006 - Rail One of the largest Rail Overhaul Companies in the UK wanted to improve their Problem Solving ability – JEL provided the answer. Before we were engaged the clients approach to problem solving was one of daily fire fighting from Team Leader to Operations Manager. There were no supporting tools in place, operators would leave their workstations to look for support. Team Leaders would provide band aid countermeasures to high profile issues. Hidden problems would equal hidden costs and morale suffered as a consequence. By implementing a wireless call system we were able to change the fire fighting mentality to a controlled and measured methodology to problem solving. This allowed the operator to call for support and team leaders to react quickly to assist and support their team more effectively. By addressing the issues live and using the STOP,CALL,WAIT philosophy meant an improved appreciation of the concerns and allowed a more robust investigation into the root cause improving the countermeasures being implemented. Through this effective problem solving costs were reduced and morale improved significantly. The change in approach was also supported by utilising several lean tools : The Wireless Andon system Consisting of one wireless base station supported by numerous call buttons , 50” plasma screens and Special 105dB speakers. All call data is recorded live and stored for problem solving analysis. PPS – a full Practical Problem Solving training programme for entire workforce. Poka yoke was introduced where possible Full works system In addition we introduced some Lean Culture Change Tools: Production Plan V Actual Performance – hourly at all levels Lean Leadership Behaviours – Go See - understand Kamishibai - for sustaining the changes “Quote” QC Tools 5Why Team Leader shadowing “We have taken lean forward with the obvious foundation tools, then again with the introduction of Takt time and we changed the area, but with Andon we introduced a change in the people..” A day in the life A Caunt Operations Manager For help with Productivity and performance contact: www.JEL-LEAN.co.uk Case Study A/015 - Automotive A major Zero tier Automotive sequencing plant was losing $425,000 per month in late penalties – JEL stopped this loss Cost in $ Downtime Costs 500,000 400,000 300,000 200,000 100,000 0 The client on a daily basis incurred line stop penalties of $500 per minute due to volume and quality issues stopping production in one of the UK’s Largest vehicle assembly plants as well as incurring high internal scrap costs. Workforce engagement and the inability to close out problems quickly compounded the issues. We implemented visual control and hourly management of each of the 4 zones and the engine assembly the line, stoppages at the customer site reduced to nearly zero, cutting the penalty payments from an average of $312,000 to $2,500. With the hourly reviews, the response to zone concerns was immediate this lead to defects dropping from 351 PPM to 22 PPM. By empowering the work force through active participation in the introduction and development of standard work instructions gave them a new focus which had a positive effect resulting in a reduction of the internal scrap cost from $215,000 to $16,000.

We were letting them down Lean Leadership Behaviours every day and needed proven expertise fast. Within days Practical Problem Solving – operator level of engaging JEL they felt like one of the team they Kamishibai - for sustaining the changes grasped the issues and quickly helped us to contain them. “After substantial short term growth and winning contract Sometimes you just can’t do everything yourselves, my only regret was not involving JEL sooner they paid for themselves in days!” Gary Brogan Plant Manager For help with Productivity and performance contact: www.JEL-LEAN.co.uk Case Study R/007 - Rail External defects reduced by 50% within 6 months through the installation of a full PPS system. Monthly Customer Complaints 40 30 20 Contained 10 Closed 0 Before we were engaged our clients customer satisfaction was poor due to a high quantity of new and repeat customer concerns. The same was true for the internal concerns both were managed through fire fighting using temporary countermeasures, with no structured problem solving activities or tools being used to reach true root cause. A significant percentage of shop floor and management staff had little to no experience or knowledge of Quality and Lean tools which could and should have been utilised in problem solving . We took the entire workforce (140 management and 430 shop floor staff) through Practical Problem Solving shop floor based training, developing a fundamental grounding in problem solving using the lean manufacturing and quality tools. Through identification of correct root cause and robust permanent countermeasures the customer confidence and satisfaction improved to extent of rewarding new business. First time quality improved from 74% to 91% by utilising problem tracker and using lessons learnt from root cause identification and countermeasures implemented through the structured approach to problem solving.

With the training of the staff, the standard approach to problem solving utilising the various tools all supported by a robust problem tracking process has shown significant results very quickly. JEL have given us the tools and mentoring to enable us to continue improving our quality performance. “ Tim Jenkins General Manager For help with Productivity and performance contact: www.JEL-LEAN.co.uk Andoncall is a cost effective real time production monitoring system which links your equipment and operators wirelessly providing instant feedback on production efficiency and capacity.
