In my job today I have to look at how I'm going to produce a certain amount of units on any given production line and if I have any problems with producing those units on that production line. Sometimes it might be equipment related... let's say for instance... if I have a defect ratio of 40 percent, then obviously I can't meet my scheduled goal on my schedule of l00 percent. I'm only going to output 60 percent of what I need to output, and that's a big problem because then my customer is not going to understand why he can't [have] that other 40 percent which is being [lost] by my production process which again relates to engineering.
So every day I look at these factors and I look at what we did the day before, what our defect ratio was the day before, how much more I need to keep onƒ the production line--because if I have units coming off the production line, that's money every time a unit is rejected off the production line.
[Kim explains how she uses algebra. She creates equations in order to set production goals.] I use algebra in - Let's say for instance we have scheduled meetings and we meet with the materials group and our planners and they sell product to the customer. Well they say, this is what we sold to the customer, and then they come to us, production, and say, what can you build? Well, they've already told the customer we can build this amount and so I have little flexibility in that.
But all I can say is, well, based on what you sold the customer which might be 92,000 units that you sold for that particular month-- I go back and I look at my averages per production line and our past performance and I take those averages and I come up with a percentage that I think we can achieve for that particular month based on our past performance and then _ there might be pluses and minuses that engineering might have corrected, and then I take all that into [an equation] and then I give planning what I think I can actually produce for that particular month. And sometimes we're pretty much very close, and then sometimes we're not. It just depends on what's going on for that particular month.
