Thanks Ron,
You numbers and mine are roughly in the same ballpark, roughly

Subject: RE: Price of the Freerunner spare parts Yes,
The information about returns and defects etc needs to be shared. First,
however, it needs to be established or estimated. I haven't seen a single
number from anybody on the demand rate for batteries or LCD or back covers.
Anyone care to guess?
~~~~~~~~~~~~~~~~
Since you asked <g>, here are my WAGs (with rationale)
Item: Projected spares demand (adjust after 6 months field
experience)
Battery 1 spare per 8 units sold
rationale: desire for spare battery more likely due to
wide range of uses
(as compared with standard phone).
If Nokia battery
is really "as good as" then this can be
lower but not zero.
LCD 1 spare per 75 units sold 9slightly more than 1 percent)
LCD breakage is not frequent, but enough that we need
spares
Back cover 1 spare per 200 units sold
not a high failure item, but a pain when it goes.
if this is not a sturdy part
with perfect fit, the rate will be quite a bit higher
~~~~~~~~~~~~~~~~~~~
A lot of money can be squandered if spares kan-bans are set too high but the
flip side of that coin is that a lot of delay for customers to get spares
leads to unhappy customers, and in some cases will trigger swapping an
entire unit which is REALLY expensive.
