Take the following contrived sentence:
Our staff's productivity has doubled since we upgraded their computers.
And now this one:
Our staff's [rate of procrastination] has doubled since we gave them new smart phones.
Is there a single word to fit within the italicised section of the second sentence?
As you can see I initially was looking for some sort of form of the word "procrastinate", but "procrastination" doesn't sound like it fits properly on its own (does it?), and I don't think the word has a valid form that is equivalent to "productivity", by which I mean that: your productivity is a measure how much you produce, while [what?] is a measure of how much you procrastinate.
