Lean manufacturing is a system aimed at minimizing waste within manufacturing processes. It was developed from the Toyota Production System between 1948-1975. The key principles of lean manufacturing include continuous improvement (kaizen), just-in-time production to reduce waste and inventory, visual management like andon cords to detect issues, and focusing on adding value from the customer's perspective. Implementing lean principles can benefit companies through improved productivity and efficiency, increased quality, and faster delivery, while benefiting employees and customers.

Each person in every stage of an organization should continually improve all existing
processes for the success of the company as a whole. If companies want to benefit from Lean
Manufacturing, continuity and learning are the keys.

10. b) Flow
Cut lead time as much as possible and identify
problems like defects, transportation, turnover
and others that can delay the process.
• Just in time -> the right product in the right
quantity at the right time.
• Continious Flow -> A system where the
production line moves so that the products
roll off just as the need arises for them.

11. c) Customer Perspective
Create value and eliminate every waste that doesn’t add value from the
customer perspective.

12. d) Jidoka
Aka Automation, it’s a practice by
which each team develop the ability
to detect odd conditions that occur,
and immediately stop the production
line. It avoids the spread of bad
practices.

13. e) Waste
Called Muda in japanese, the goal is to eliminate anything that happens to a
product or service that doesn’t add value from customer perspective. We
count 7 of them.
E.g. : You break your leg, you go to a Hospital. You spend 2 hours in the waiting room until a doctor
examines you for 5 minutes to tell you ‘son, your leg is broken!’. Then someone put you a plaster, which it
lasts 25 minutes. On 2 hours and 30 minutes, only 30 minutes added value from your patient perspective. If
this hospital intends to be lean, it would try to identify and eliminate all the wastes to reduce those 2 hours
that added no value to you, the customer.

14. There are 7 identified kind of wastes
1. Overproduction : inventory is a waste. No customers ordered anything.
2. Waiting : periods of inactivity.
3. Transporation : moving between places, between work station
4. Inventory : excessed supplies, work in process, unneccessary material
5. Motion : useless motion of people or equipement. Inneficient layout.
6. Overprocessing : rework and reprocessing that add no value to the product
7. Defective product : returns, claims… anytime the product fail to its expectations or
specifications
+ 8. Talent : nowadays talent is a considered as a waste. Some people have amazing
talents
