Handling external factors in project definitions
Hi there, I've been lurking for a long time this great community, and finally I've decided to ask a doubt that has been on my mind for a long time.
When naming a project, the usual wisdom is phrasing it so you make it dependent on internal factors, things upon which you have control (for example, 'having 2 new products by ...' You go through the toil and then you have 2 new products).
But now and then I found projects that are dependent on an external measurement, for example 'Get 4,700 unique visitors for my web by...'. I don't see a way to reframe a project like that to put it into personal control. What would you do in a case like that? I don't have the reference here, but I think in 'Making it all work' there is an example project that goes 'Increase sales by 5% by ...', which is, again, out of one's control. What's your experience about this division? Thank you
