Real-Life Decision Making -- Solution
You recommend that the parts be manufactured using close tolerances,
and that stainless steel be used.
Because the parts are expected to run throughout the life of the plant,
which could be 50 years, you believe close tolerance and better materials
are needed. So, you recommend that the parts be manufactured using close tolerances,
and that stainless steel be used due to its strength. However, because of
the high cost, your company requests a detailed explanation of your decision.
You explain that the parts are expected to last 50 years, and lax tolerances
and cheap materials won't produce the required results. You also explain that
the more expensive parts are safer to use.
You point out that if you build something that's going to last, though
the cost will be greater in the beginning, the parts won't wear out as quickly
and the customers will be better pleased with the results. Since the parts
won't have to be replaced in five years, the companies will experience cost
savings down the road.
This is a real-life decision made by mechanical drafters every
day. There is no one answer for all situations. It depends on various factors,
including the function of the parts, safety considerations, and the economics
involved. Remember one important thing though: you really do get what you
pay for. Better made parts will last much longer than their cheaper counterparts.
Convincing your employer to spend more on better quality parts can be difficult,
however.
"I think a lot of employers don't want to put up that cost upfront," says
drafting instructor Christina Heinrick. "It's short-term thinking sometimes,
rather than what's best in the long term."
