Analogies

[robmoffat]

I've written a further piece of work in the Estimating series.

https://riskfirst.org/estimating/Analogies

There have been four other parts to this - Fill The Bucket, Kitchen Cabinets, Journeys and Fractals. This one tries to bring them all together in some way, but you don't really need to have looked closely at those other ones to appreciate what I'm talking about here.

Would love some feedback as usual.

Hopefully this is paving the way to talk more about how change affects estimates, and then start talking about agency risks a bit, but that'll be in 2020.

Merry Christmas!
