Now, let me, at this point, refer you to an important difference between
project management and process management.
Process management, the topic of this course,
is all about doing things repeatedly.
You want to serve hundreds and hundreds of customers over the day.
And at this point I'm primarily interested in computing the flow of customers through
the process.
It turns out that for the flow of customers through the process, it doesn't
matter whether we work stations one, two or three sequentially or in parallel.
If all you have to do is make one sandwich it would be lovely to, for
example leaving out the customer, just station three in parallel
to station one and two, but at the end of the day every customer here
on the flow has to go through station one, two and three.
And so we are not going to serve any more customers by working in parallel.
