    Hi
    I would like to know if anybody has been involved in applying 6s to reduce the LT without affecting inventory and cost adversely. Any ideas on this subject will help.

    You’d better take a look at Lean tool kit.
    Anyway, I think the best way to start is to map out the processes and start to record the operative cycle time for each process to define the weakest link.
    I have been working on a computer program, which will calculate DPMO, Yield, Sigma Level and Cycle Time. The program may help you record the operative cycle time for your processes and help you manage the Internal CAR.
    Send me an email, I will forward the program to you.

    Hi,
    For lead time reduction the following are some metodologies available.
    1. SSSS- Six steps to Six Sigma
    2. TQSS- Transactoinal Quality to Six Sigma ( Wipro’s Developed)
    3. CFPM- Cross Functional Process Mapping.
    Thanks & Regards,
    Mannu

    Does anyone has recommendations on how to reduce WIP also??

    Venky,
    You may want to explore a combination of Lean and Six Sigma. Specifically supplier kanban and then Six Sigma analysis of your MRP variables. (analyze variances and reduce safety stocks EOQs compare Lead Times and fix the fliers)   If you set up a pull system with your supplier, you will need to take a second look at Lead Time calculations in your MRP system and reduce accordingly.
    You could get more Lean info on the LEI website
    regards & good hunting

    Hi “Flow Guy”,
    I guess you mean http://www.lean.org/ when you state LEI ?
    Regards,

    Again, the Lean tool kit. Kanban pull system, one piece flow and takt time target on reducing inventory/WIP which is one of the 7 wastes.

    I keep receiving emails asking for the program. Please make sure following items before sending me email.
     
    1)      It is a Microsoft Access program. Make use you have Access installed.
    2)      It is not a calculator. It is a database that keeps production data (input, defect, operational time) and calculates Yield, Sigma Level and Operative Cycle Time.
    3)      It is primarily designed for manufacturing processes to record and generate reports/charts for production performance measurements such as Yield, and Cycle Time. I don’t know if it fits to service industries (I think it can).
     
    Thanks
    Logan

    This is an area that has lots research done. You can look at Quick Response Manufacturing (book by R Suri) and Fasctory Physics (Spearmab abd Hopp). Note you cannot reduce lead time without decreasing WIP (Litle’s Law: Wip=throughput*leadtime)p.s. I do have other ideas but these involve commerial stuff so I will not post them here.Greg Diehl

    If you want to reduce WIP, you could start by reducing the batch size (thats if it is possible). Leadtime is a function of the batch size. By doing this make sure that you look at set up times within your process. If you can reduce set up times then you can look at reducing the batch size. Remember if you can save on 20% of your set  up then you could reduce your batch or lot size by 20%. But remember WIP is there for a reason. It make people feel comfortable and tpically hides away problems. So by removing the WIP you will get very aggitated people and you will expose probems. You can typically use the SMED approach to reducing your set up times. Hope this hellps.

    Hi!
    Can I get a copy of your program to control production in my company?
