    Does anyone have any statistics on the error associated with using hand counted inventory? Or any propaganda to support using barcoding inventory.

    You can create your own statistics using GR&R.
    Repeatibility and Reproducibility. That’s why this concept was introduced, to assess how good a measurement system is.
    Personally, statistics fr other people who may be at the other part of the world doing same hand count inventory method could mislead you coz you may not count the same animal, not to mention human nature which tends to differ over countries, continents, etc
    Thus; create your own statistics by doing GR&R. That’s the best answer to your qs

    If you lean out your inventory / set appropriate kanbans or processes for the different classes of inventory your issue will go away.

    You must have missed the post were Darth called me a “Slacker”.
    It true I am a lazy slacker but I also need to turn in a capex by the end of the day to get the most out of a window of opportunity that just came open.

    Ezwald,
    I can give you two examples from the medical testing industry:
    1. Barcoding of specimen inventory (WIP) reduced the number of lost specimens from 840 to 3 in one year. It reduced the number of misplaced specimens from 2,000 a month to approximately 0. A lost specimen results in lost revenues of up to $20,000 per client per year. The total savings for the first year of implementation is estimated at $1.6 Million annualized.
    2. A large processor expectes savings in the amount of $65,000,000 per year by using a barcoding system that allows for reduced inventory and JIT supply chain management.
    These are numbers that were used for the justification of large-scale lean Six Sigma projects for 2006.
