 "No we were going to keep
it simple. If we debounce the switch then we add a requirement to keep track of time. I would like to keep such
things out of the software if possible."
"Sounds like a bad design decision
to me."
"If we find out we need it
we will just add it later, XP allows us to act as if future requirements don't exist, you'll see. Next we need
to talk about functional testing."
"We don't test our products
we send them off to QA. They test it and tell us what is broken. We fix it and send it back again until everything
is working."
"I was thinking of a different
scenario. Suppose we send a product to QA that has no bugs?"
"That has never happened."
"We can at least try. What
we will need is a computer with a 32 bit PIA to connect to the microcontroller we are building for the coffee maker.
An additional PIA to control the coffee maker's power would also be good. We can then program the functional test
computer to run scenarios on the coffee maker's microcontroller and test it completely before it even goes to QA."

"We could make something available
near the end of the project, but you will need one of our MDL's and a FLASH burner for it to do you any good. That
kind of equipment is already in short supply. You guys have a lot to learn about building commercial software!"
"I suppose if you could help
us verify a software simulation, which we could then supplement with an occasional run on real hardware that would
be enough. We would also like to do a spike solution before we attempt to cost out this project. We will need a
prototype coffee maker. We want to try a simple experiment of reading inputs and controlling outputs."
"We haven't finished our design
yet. Circuit boards won't be available for awhile."
"How about if we wire wrap
something together quickly that just has the processor, brew button and the indicator light?"
"We can help with a schematic
and show you how to burn the FLASH memory, if you do all the wire wrapping."
"Agreed."
Next let's see how the rest of the
team is doing with the FADD helping them create user
stories. |
