That's a bad place to be stuck in. I'll see if I can put something together that makes sense and is fairly comprehensive. At the moment, a lot of it is "I know it when I see it" but that's not exactly helpful.
Fortunately we seem to be moving away from that now-days :)
And I have talked with our guys and I can sort of see it from their view-point. from their point of view it often is the hunt for the last `checkbox`, the last necessary tick somewhere on the customers requirements page.
In their mind it often seems as a simple calculation, on one hand potentially so much $/year from big-corp vs 2xManxMonth to get a new feature over the line? No brainer.
An I am struggling to somehow explain that you need to add much more to those two developer months, because with every feature there are bugs and regressions and customer tickets, e.t.c. and suddenly it takes one developer in perpetuity.
Much as a salesman can tell when a customer is saying "I would most certainly give you money if you turned your product upside down and painted it blue", which is correctly translated as "I will never buy your present offering."
