Implies a continuous improvement of business processes through the elimination of waste
Achievements with a lean project?
Less effort Fewer means
Better use of people Faster
On a smaller surface Less inventory
a. Preface
Lean manufacturing = lean production = Toyota Production System (= TPS)
4 employees developed the TPS based on British and American principles
Toyota managed to
o Significantly reduce its cost basis
o Improve quality
o Become one of the leading companies in the world
90’s LEAN philosophy conquered the West
Mostly in production= lean manufacturing
Later in administrative environments= lean office
b. What made Toyota different?
traditional production Toyota
company
•economies of scale = mass •focused to client value
production
•strong hierarchy •flat organisation

c. Basis idea of lean
- Perfect processes leading to perfect results
- Eliminate waste and as such reduce cost become more efficient
i. Perfect processes
The client determines value
Every step in the process adds value for the client
Each step in the process has to be:
- Capable does what it has to do
- Available not absent or broken
- Adequate enough capacity
- Flexible responds to changes in client requests
ii. MUDA
Value added activity Activity that creates value for the client, for which the
client is prepared to pay
Class 1 MUDA: - Activities that create no value, but are necessary
Non-Value Added but Required Activity - Make those as minimal and efficient as possible
Class 2 MUDA: - Create no value for the client
Non-Value Added Activity - Eliminate
d. The 7+1 forms of waste
over
production
waiting defect
under
utilised
transport: if talent
not valued inventory
adding
over
movement
operation
e. Standard processes
- Written processes describing the most efficient way to produce the highest possible quality
in a safe manner
- The only acceptable way to execute the process
- With continuous improvement
- Minimizes variation and increases consistency of output
