The Earned Value method to keep track of project performance

This method is a little different from the classical approach of keeping track of project performance. It has an extra variable that represents the actual cost of the work done at a given point, and it is obtained from the organisation 's accounting system. This data is compared with the earned value to show the project's performance situation running over or under. So, it's possible, at any given point, to compare how much actual work has been completed against how much is expected to be completed. This makes it possible to measure performance and predict the outcome of project.

Structuring into forms

These problems representing the characterization of a phenomenon or process could be modelled at an abstract level by extracting common qualities from specific examples.The process of formulating generalized concepts enables a better understanding of complex issues and, consequentially, the resolution of complex problems.
Therefore, modelling starts with the use of abstraction for the understanding of the problem and the use of methodologies and techniques for the implementation aspects. 
A model has three essential parts:
(i) a process or phenomenon which is to be modeled,  (ii) a mathematical structure capable of expressing the important properties of the process to be modeled, and
(iii) an explicit correspondence between the two.
The first part of a model is a phenomenon or a process which is to be characterized mathematically. For example the execution of a program, the allocation of resources of a computation center, and the flow of information in a computer network. The real wor…
