JIT Philosophy
„
„
„
„
A systems approach to developing and operating a manufacturing system
Based on the total elimination of waste and producing only the necessary
units in the necessary quantities at the necessary time by bringing
production rates exactly in line with market demand
Inventory is seen as incurring costs instead of adding value
Ideas:
„
„
„
„
Statistics
Industrial engineering
Production management
Behavioral science
History of JIT
„
„
„
„
Originated in Japan and generally associated with the Toyota motor
company
Initially known as the "Toyota Production System".
Taiichi Ohno is most commonly credited as the father/originator of this way
of working
JIT philosophy arouse out of two things
„
„
Japan’s wish to improve its production quality
Kaizen (Continuous Improvement)
After the Second World War the president of Toyota said "Catch up with
America in three years, otherwise the automobile industry of Japan will not
survive".
Founder of JIT
„
Pioneered by Taiichi Ohno in Japan
„ Father of Toyota Production system (Lean Manufacturing)
„ Wrote several books about the system
„
„
„
„
“Toyota Production”
“Just In Time Today Tomorrow”
“Toyota Production System: Beyond Large Scale Production”
Employee at first then rose through ranks and became an
executive
Key Elements of JIT
„
„
„
„
„
„
„
Reduce and eliminate setup times
Reduce lot sizes (manufacturing and purchase)
Preventive maintenance
Flexible work force
Small-lot (single unit) conveyance
Require supplier quality assurance
Reduce Lead Times (production and delivery)
Order Winners & Qualifiers of JIT
„
„
„
„
„
„
Customization
Improved Quality
Time consumption
Flows of goods from warehouse to shelves are improved
Focuses on processes rather than results
Focuses more on team dynamics
Requirements for JIT
„
Each manufacturing process is different in terms of goals, production
requirements, etc.
„
To establish a JIT manufacturing system, every department must have
commitment to a common goal, which also needs to be supported by the
company’s top management.
„
Financial commitment is necessary during the early stages of development
and implementation to change over to a JIT system.
„
Management needs to be at the top of their game in the early transition
phase of JIT.
„
Trust and commitment between the supplier and the customer is a must.
Process of JIT
1. Buyer receives
order
2. Cases the order
3. Prints case
labels
4. Creates ship
notice and
invoice
5. Connects and
sends
documents
1. Specify value in the
eyes of the customer
2. Identify the value
stream and eliminate
waste
3. Make value flow at the
pull of the customer
4. Involve and empower
employees
5. Rinse and Repeat
Problems with JIT
„
Major problem is it leaves the supplier and downstream
consumers open to supply shock
„
With shipments coming into a company several times a day
they are susceptible to an interruption in the flow
„
Most companies have to use two suppliers for most
assemblies
