Question: CoSysMo is a detailed, systems engineering planning tool. It predicts person months by looking at size and effort factors. But there is also a "calibration" factor called "A" in the equation:
What does "A" really represent? Elaborate on the real meaning of a "low A", a "high A" and how significant the business ramifications are to this number
Develop a CoSysMo prediction of person months (pm) required given the following data:
i. Previous performance against CoSysMo predictions that used an "A" = 1 are as follows:
Prediction using A = 1
Actual PM Required
125 pm
190 pm
85 pm
125 pm
105 pm
157 pm
ii. Economies of Scale are nominal at 1.0
iii. Requirements are balanced between normal and difficult with 150 of each.
iv. There are 12 interfaces and each one is going to be difficult
v. We have only 3 easy algorithms to develop
vi. But we have 3 really difficult scenarios that must be managed.
vii. We have done something similar in the past so our understanding of the requirements is nominal.
viii. But the technical risk for this effort is very high. This will have people "in the loop" and it cannot fail.
ix. Because of ups and downs in our industry the continuity of our team has been low and this must be addressed.
