Description of a Lean Company • Lean is completely about CULTURE, or the “Thinking Way”. • Lean is not a part of what we do, it is in everything that we do, it is our way of thinking. • It is an embedded culture of understanding the customer’s needs, continually striving to reduce waste and optimising the performance of process, people and infrastructure. • At all levels there is a strong desire to be better. • A culture of Lean is visibly prioritised and practised from the top to the bottom of the workforce. • The key is understanding the customer and delivering his requirements. www.beyondlean.com
Lean…. • Improves business performance using simple, practical tools and techniques to enhance quality, cost, delivery and people contribution. • Exposes the wastes in the system • People have to change their long standing work practices and ideas • Senior management will have to drive lean principles forward with total commitment to its success • Not a “bolt on” technique, more a way of life leading to a total change in culture www.beyondlean.com
Incidental Work (NVA), but unavoidable with current technology or methods. Any work carried out that does not increase product value Waste An activity that does not add value to the product and hence something that you don’t want to be doing, hence ‘Waste’. Types of Work – Identifying Waste Non-Value Adding,but unavoidable with current technology or methods. Any work carried out that does not increase product value Value Adding (VA): Any activity that directly adds value to the product www.beyondlean.com
Waste Elimination Non-Value Adding,but unavoidable with current technology or methods. Any work carried out that does not increase product value • Traditional Focus • Work Longer-Harder-Faster • Add People or Equipment • Lean Manufacturing • Improve the Value Stream to Eliminate Waste Value Add Waste LEAD TIME www.beyondlean.com
Non-Value Adding,but unavoidable with current technology or methods. Any work carried out that does not increase product value QUALITY PRODUCTS Defects should never be passed on to the following process The idea that defects are the responsibility of inspection specialists at the end of the line does not exist Incidental Work (NVA)E.g. Inspection www.beyondlean.com
Value Added (VA)E.g. Good Thinking…. ….Good Products Employees are not expected to simply routinely do their job but are expected to contribute to the improvement of their own work operations, utilising their own personal experience, knowledge and creativity. On the remaining slides are brief overviews of some of the ‘Lean’ Tools www.beyondlean.com

Job security Good working environment Reasonable salary & benefits Quality products High productivity Flexibility “If we always do what we always did then We’ll always get what we always got” People and Organisation Lean Transformation:- Lean will touch everyone • Is more than just a new way of manufacturing. • It is going to challenge & change the whole organisation. • Success depends on the people in the organisation and their acceptance and commitment. Customer Management Good Quality Product On time every time Shared Benefits Customer Service Build a Partnership Less firefighting Improved relationships Expects Expects Leadership The WILL to improve DO it! Workforce Change Inspire the BELIEF Provide the TOOLS Invest in job creation Create a long term future Provide everything for the job Create a change environment Encourage innovation Work together for a common goal Give people more skills Provide the tools to be the best Create a safer & cleaner environment Clear and consistent communications Have the skills for the job Involved in problem solving Work smarter not harder Raise & solve problems Create sustainable improvement Less frustration Ownership of cell targets Team working Innovative culture Just do it! You’re not a failure if you don’t make it. You’re a success because you try. Business Employee Change the way you do things, be different - be the best! www.beyondlean.com
Visual Management and Control What we can’t see we can’t improve Visual Controls are simple, clear and concise visible indicators such as charts, diagrams, lights, measurements, floor markings,locations and signs. Always get everyone in the workplace involved Targets A picture paints a 1000 words Achievements Visibility of parts status,quantity & order level. The aim of all these indicators is to make it immediately obvious to everyone the current situation or desired status of a machine, resource, assembly or cell and to expose the ABNORMAL undesired status so that action can be taken to rectify it immediately. Poka Yoke Colour coding SHADOWBOARD Every day use of lights being used to display actions, allowing you to take control your situation. 5C driven initiative www.beyondlean.com

5C Workplace Organisation & Housekeeping The 5C’s are actually steps of the technique that begin with ‘C’ and are utilised to create a workplace suited for visual control and lean production by enabling waste elimination, standardisation and continuous organisation of the workplace. This technique was first developed in Japan by Toyota and used 5S’s. 5C is a foundation for continuous improvement. Without 5C all other improvements will be lost. The aim of 5C is to:- Improve the work environment Reduce wasteful activities Encourage visual controls Enhance team working Reduce frustration Increase efficiency 5C's 5S's It is all about having what you need to do your job when you need it.

Seek it out and get rid! 1 Over Processing Inventory 7 2 Processing beyond the standard required by the customer. Raw material, work in progress or finished goods which is not having value added to it. Rework 6 Waiting 3 Non right first time. Repetition or correction of a process. People or parts that wait for a work cycle to be completed. 5 4 Transportation Motion Unnecessary movement of people, parts or machines within a process.

Levelled Production • The pre-requisite of Just in Time working. • Levelled production maximises the benefits of Just in Time by smoothing both the quantity and variety of parts over a production period. Cycle time 30 Mins 20 Non-Levelled Production Levelled Production 10 Overworked Mins Mins Product 60 60 Under-utilised Product Product • Avoids overburdening through even distribution of work • Consistent production supporting customer demand • Improved labour effectiveness Benefits of Production Levelling are: www.beyondlean.com
Pull System Pull systems rely on the customer order ‘pulling’ material through the production system when it is required. The system can be thought of as a chain reaction,initiated by the customer withdrawing parts. KANBAN Fill-up Pull Kanban is not a system, but a means of communicating customer orders through the manufacturing process. There are 3 main types:- Production Instruction Kanban Parts Withdrawal Kanban Tablet Kanban • all parts are available in this system (like a supermarket) • kanbans are used to authorise replenishment and control build sequence • the rate of production is controlled through the levelling board T PW PI Sequential Pull Factors for type of pull Sequential Pull Fill-up Pull x High product variety Large product size Short shelf life Manuf LT > Cust LT High variable demand Unreliable process High piece cost x x x OK BEST x x • parts are built to order. Customer lead time must exceed production lead time • production is triggered at the point at which the variant is defined, via a sequence list • tablet kanban is used to authorise production or withdrawal, but does not specify variant • FIFO principles must be used to ensure production sequence equals demand sequence www.beyondlean.com
Takt Time ‘Takt is the German word for ‘beat’ and represents the pace at which the customer requires the product. Takt is therefore used to determine the rate which parts have to be produced throughout the shift. Takt Time = Total production time available* Total customer demand *(does not include breaks, meetings & clean up time) eg: Total time available = 5 Hrs Customer demand = 10 units Therefore = 5 x 60mins takt time 10 units = 300 mins 10 units = 30 mins This means that each process needs to complete one unit every 30 mins to satisfy the customer demand of 10 units in 5 hours. Current Future Takt allows the work to be balanced, which frees up machines and operators.

Just In Time What is Just In Time? Just In Time is:- “Manufacturing and conveying what is needed, when it is needed, in the amount that is needed, at the quality required and in the shortest possible lead time” Continuous JIT has 3 parts, based on one pre-requisite.
