Before
starting of any project, cost for that particular project can be estimated
roughly. To calculate this approximate cost there are two ways which are called
as Historical cost, where you look at other previous similar projects &
estimate the cost & the other method is "Expert judgment" where
knowledge of expertise are taken into the consideration.
We
have done few calculations regarding project cost calculation & learnt how
to calculate the payback period & how it effects the project. When
selecting a project solution we must select the project with the shortest
payback time.
We
have done a case study of implementing an edm for APIIT & identified what
is the cost effective method (PHP or .NET) when developing the software.
Also
it is identified how to proceed with projects based on NPV (Net Present value).
If
:-
NPV
> 0 Accept the project
NPV
= 0 Accept the project
NPV
< 0 Reject the project
NPV
1 < NPV 2 Then Choose NPV 2
