Before starting today Discussion -  All above mentioned topics will Lead you towards one Concept & That is " Improvement of Business process & Intent to decrease Process variation & Improve Customer Satisfaction"

Above topics are Tools which will lead toward above mentioned resultant.





 Lean - A philosophy of production that emphasizes the minimization of the amount of all resources (Yes, Including the Time) Used in various activities  of the enterprises. it involves identifying and elimination non value added activities in design, production, Supply chain management and dealing with customers. 

It Contains a Set of Principles and practices to reduce cost and removal of waste and simplify all Process (Manufacturing & Support ). 



Lean matches Supply with demand by providing only what is in demand and only at the rate it is demanded. This Might mean slowing production when demand slows. 

This set the pace for Logistics activities also. Logistics professional are empowered to match customer service to customer priorities eliminating unnecessary service feature.


                                   Lean = Non Valve added (Definition of waste)

            Eight Form of waste :

  •  Transportation -      Excessive Movement of People, Things Or information 
  •   Inventory -             Storage of Materials prior to Demand signal 
  •   Motion -                  Unnecessary handling , walking, driving, bending, lifting, reaching
  •  Waiting -                  Idle time caused by lack of direction, instructions, information, parts or                                            Equipment 
  • Overproduction-    Make more than Immediately required 
  • Over processing -   Higher grade materials or tighter tolerances than required
  • Defects -                 Scrap , rework & erroneous Documentation
  • Skills -                  Worker Underutilization or empowerment Beyond Capabilities


 -    What is Muda, Mura & Muri  ??? 

Lean Takes a problem solving approach to waste, Looking for waste in one of three major areas. 

 Muda - Activities that consume resources but  create no customer value
 Mura -  Demand or activities ,that are Inconsistent or unformal or uneven
 Muri -  Overburdening of workers & Process 


 


    Just in Time one of Lean Concept & Pillar of Lean House.. 
 
A philosophy of  manufacturing based on planned elimination of all waste and on continuous improvement of Productivity. It  focus on successful execution of all manufacturing activities required to produce a final product. 

Four Elements of JIT ::

- ZERO INVENTORIES 
- SHORT LEAD TIME
- SMALL INVENTORIES 
- HIGH QUALITY PRODUCTS (ZERO DEFECTS)

Jit allows delivery of right Items at the right time to right place in right amount . 


TAKT TIME -  The Pace of Production to match the rate of customer demand. It also Facilitate JIT

                       Takt Time =     Available Production time/ Customer demand

                                        


Lean Concepts are really a Long topics to discuss and also Important for any course in Supply chain management..
