Design Tradeoffs

Having spent several rounds of initial specifications with a potential
customer, that is less likely to be a viable project as they want to

"Squeeze a gallon into a pint pot"

I could see that the prospect was actually trying to get all THREE
sides of the Quality Triangle often referred to as Tradeoff Triangle

Good
/ \
/ \
/ \
/ \
Fast ---- Cheap

"Pick any two"

I actually think these days it should become the

"Tradeoff Square"

Good ----------- Small
| |
| |
| |
Cheap ------------ Fast

"Pick any THREE"

In the ever miniaturising world of keyboards too small for anyone
other than a mouse to use.

Often good means performs the perfect job, but it must the size of a
postage stamp, cost less than $1..

An often seen example is often expecting to get broadcast audio and video
quality out of a camera smaller than a webcam, at full HD frame rates,
with half hour full quality storage in MPEG-4 in real time, on postage
stamp size PCB and costs $1.

That is what I am doing too often saying 'no', and in one case
definitely does not understand the triangle/square.

I see projects having 4 factors and a variation in one factor effects the
other 3.

QUALITY
COST
TIME
EXPERINCE

If you want a cheaper product then you can reduce the quality /
specification.

AND another major problem is the client's have done they business plan
homework for the product.

I sense a bit of cynism about their 'homework' there..

Sorry - I meant "haven;t" done their home work.


I had some asked me to build an RF product.... but with out understanding
what was required and how much work was involved... more than just the
electronics..... tooling for plastics, hardware and
mechatonics... Geez..
