    Hi All,
    I am a full-time BB who is trying to find the best way to present a Six Sigma project.
    Basically, the project is related to the repair of a product that requires installation of accessories. These accessories are bought from a vendor and are extremely pricey.
    My team came up with a good technical solution that allows us to reduce the repair cost of the product via ‘clean, inspect and reuse’ of one of the accessories. i.e salvaging those that came originally with the product.
    Now the challenge: What should I define as the ‘Y’ or howshould I measure as the output. Due to some complicated financial system setup, using the ‘cost’ of repair as the output measurement is out. I thought of using the salvation yield (previously 0%…now 80%) as the output measurement. However, this seems does not fit well into the DMAIC process, which is a mandatory approach for this project.
    Please help advise how I could scope the project ‘Y’ or output.
    Thanks so much.

    So, how did you “come up with a good tech approach”, without identifying your Y=f(x)’s up front in “D” of DMAIC?
    For reporting purposes, you need to focus on the bottom line improvement(s) to cost/quality/delivery…period. 
    For instance:  Quantify the savings from cannabalizing parts instead of buying new.
    “Due to some complicated financial system setup, using the ‘cost’ of repair as the output measurement is out..”  -This is fishy…You ned to push back w/ Finance, who, hopefully was engaged in this project from the start

    “My team came up with a good technical solution that allows us to reduce the repair cost of the product via ‘clean, inspect and reuse’ of one of the accessories. i.e salvaging those that came originally with the product”Understanding what you have suggested is important (not saying right or wrong):1. Warranty is affected because of the life cycle issue you have with the cannibalized parts with time on them. What are the customers’ expectations?2. Why did the other parts fail and what affect has this had on the swapped parts? 3. What checks have you put in place to ensure removal and re-installation of the parts have not made the system worse?4. Will the vendor cover the reinstalled parts?Cannibalizing comes with a price that you need to understand. We did it in the military for years to reduce downtime for the mission. Costs to rework were not addressed because the mission was more important. Canning’ parts also become habitual which has its own unintended consequences. Now with that said, you were asked what study you did in the define phase to make this decision… it still applies.

    hbgb b^2,Thanks. I had to crawl into too many aircraft fuel tanks to canx fuel probes when we we were low in supply… guess what the probes kept breaking. It also takes a long time to defuel, purge, and refuel for testing not to mention introducing risk to the me the worker. It is okay though… the fule fumes did nothing to my brane.
    Thanks
