You forgot one parameter: Response time. As far as I know, phase III
doesn't even have a design goal for response time, only a naive hope
that it will be "as fast as possible", which in reality for the last
week seems to be an average of 1.5 seconds, with 8% of requests taking
more than 5 seconds. It has been far worse at times.
I think that phase IV should have a design goal for response times,
and that your specification should outline a way to monitor them and
keep them within the goal. I suggest setting a goal for the average
of 1.0 seconds and no more than 1% should take more than 5 seconds.
In my experience, it is slow response times that make users leave a
website never to return again. Lack of features or ugly design isn't
half as bad.
A way to measure churn (the rate at which users abandon the site)
would also be nice.
