Cost Savings of reduced Queue times
Cost Savings of reduced Queue times
(OP)
Hi,
I'm a new IE/ME engineer and I've been asked to do some justifications for new machines. Some of the savings I can easily quantify, for example reduced run times, reduced scrap, but I'm having issues with quantifying the cost of excessive lead time.
For example one of the new machines could save 3 days on a process, one that we would otherwise have to send outside.
Being new to this I am asking for any all advice and opinions. How have you provided a cost justification on white space for senior management? Are there any texts I should read to familiarize myself on this subject?
Many thanks in advance!

Make sure you properly calculate the inside cost versus the outside cost. Do not include any of your fixed overhead cost. These cost will be present if you make or buy the process being performed.
Those are the typically cost savings calculation for such a case.

Nevertheless, his MBAs (he was apparently drunk when he hired the first one) sold off our in-house machine shop and outsourced all the work, to vendors who eventually and inevitably screwed us over because they had other customers who were less penurious, so we missed some important dates, by a _lot_. ... by much more than those damn MBAs ever 'saved' in their entire damn careers.
My friend has since died, and the company has shrunk and changed hands a couple of times. I expect to see it on the block again shortly.

> In order to fully justify in-house capability, the in-house capability must be able to generate sufficient revenue for its required return on investment (ROI).
> Is there a sufficient market advantage for quick turnaround? Can you charge a premium, or can you show that your market share would increase because your turn times are quicker?
> Is there sufficient evidence to show that your outsourced work is not as efficient or cost effective as doing it in-house, i.e., the turn times are never as quoted, or workmanship is poor, or cost is not as required?
Generally, the load analysis on in-house is the killer; you must have sufficient in-house volume to adequately sustain the machinery, or the turn times are sufficiently lower enough to allow you to accept contracts that you might not otherwise be able to fulfill.
