RE: Cost Discussions
Mike,
What's happening in 802.3af right now is the result of a number of new
people who have joined the group who missed the "cost/price" lecture. We
have found that doing things with relative costs (dimensionless numbers)
works well. For example, if Solution A has a cost of 1.0, then adding
Feature B increases the cost by 2%, or something. This worked for us.
It's tricky.
Regards,
Steve

Jim, Geoff,
I hate to sound stupid my first time out, but isn't one person's
cost the previous person's price ? So I cannot talk about optics
module costs, or ASIC costs since I purchase those components at a price.
What rule can I use as chair to determine whether people are
truely talking about the cost of something?
thanks,
mike
