# IT Project (Mainframe) – Risk

To know if risk is involved in an IT project ,we need to calculate two values: one is MEAN and 2nd is SD (standard deviation).

Formule:

SD==> (PE-OPE)/6

Percentage ==> SD/Mean==> for example, percentage is 10.90, that project we treat risky.

Note :-Read my previous post for more clarity: [http://srinimf.com/2011/07/03/it-project-estimation/](http://srinimf.com/2011/07/03/it-project-estimation/)

**General thumb Rule to decide Risk:**

If the percentage is higher than 10, we treat the project is** in RISK.**

So, the one which has higher percentage of all (and  greater than 10) call it high risk project.
