Q

What is the formula from cocomo II

A

E = (A) (KLOC^b) (EAF)

E = effort in person months
A en B = given
KLOC = number of lines x 1000
EAF = given -> contextual, between 0.9 - 1.4 (effort adjustment factor)

Same as power interest grid, with power (low to high) on the horizontal axis and support on the vertical axis (low to high).
Shows which of the stakeholders support your ideas and also if they can do something about it.
From left under to right under, to left top to right top:
Weak opponent
Strong opponent
weak supporter
