3 Understanding and objectives of lean production systems (LPS) Definitions LPS are operating instructions for the production of products and services and support the planning, operation and continuous improvement of production processes. nnovative organizational concepts/components that have proven to be a best-practice solutions, are matched in an overall system. /Fraunhofer AO/ LPS can be understood as a dynamic network of design principles, methods and tools for the planning, operation and ongoing improvement of business processes. t is run with a high degree of employee participation. /MTM/ Objectives Structuring, describing and quantifying the strategies, methods and instruments / tools associated with the value creation process Representation of interlinkages and interdependencies between the individual components Establish transparent and comprehensible but also flexible standards for the entire company Management philosophy Focussing on overall optimization of production instead of pursuing solutions for single point optimizations

4 Structure of lean production systems specification Objectives (delivery, costs, quality) Principles (process orientation, pull, prevention of errors, flexibility, ) Methods (Poka Yoke, production levelling, Milk Run & supermarkets, Kanban, Kaizen, 5S, PDCA, Jidoka, FMEA, ) normative production management strategic production management also called: elements / sub-systems / modules / field of action Functions to achieve corporate objectives Bundling of methods Also called: components / concepts approaches to implement the single principles Tools (manual, operating instructions, team meeting, Schulungen, brainstorming, maintenance plan, Kanban-card, workshops, interview, qualification matrix, KP-board, audit check list, ) operative production management Also called: instruments / techniques Supporting implementation of methods

5 Phases of development of lean production systems Taylorism Division of labour Mass production Fordism REFA Assembly line production Standardisation Toyotism Toyota produktion system (TPS) Lean Thinking nnovative work organisation Lean Management Production Administration Manufacturing Volvoism Group work decentralisation Processes ntegration of isolated elements of production organization Applicability in all business areas (not fixed to production) LSP Origin: automotive industry, especially TPS Applicability to all industries / business types

16 Conclusion LPS consolidate and systematise the manifold organisational approaches in an overall framework they ensure a stringent alignment of methods and tools in use to superordinated business objectives LPS are becoming increasingly widespread among companies of different branches, sizes, sectors the content of LPS has multiple impacts on the organisation of production of a company overall, the definition and implementation of a LPS seems to be a success story 17

17 and future challenges often companies see the introduction of LPS still highly bureaucratic (focussing on the creation of the manual, staff positions, ), the true "spirit" is to be anchored better / more consistent in many cases stronger consideration of environmental issues requires critical analysis and possibly adjustments/changes to the pool of well established lean techniques and methods adaptation of the method level to the needs of a demographic change among labor force (within the standard element work organization) continue to force the transfer of the successes in the use of LPS contents on industries/ processes beyond automotive/production 18
