Risk

Risk is a module which helps in the recording and managing of risks.

The module allows the creation of risk event class node types. These risk event classes have the following properties:

Title

A title e.g. "Hard Drive Failure".

Description

A description e.g. "A complete failure of our server's hard drive resulting in the
total loss of all data."

Mean

The expected mean number of occurances of this event per day. This is often a very small
number e.g. 2.74E-4 = 0.000274 would correspond to about 1 failure every 10 years.

Profit

The total profit (positive) or loss (negative) associated with the event e.g.
cost of new hard drive + administrators time to install and restore from backups + loss
of buisness due to downtime etc.

The module calculates some useful summary statistics using the Poisson distribution (which may or
may not be appropriate) e.g. probability of 0 events in a specified period (default 30 days),
probability of 1 or more events in the specified period, expected profit in the specified period.

The module also has two blocks:

• Most Exciting Risks which displays the events which are expected to cause the most profit.
• Most Scary Risks which displays the events which are expected to cause the most losses.

The risk module is currently compatible with Druapl 6.x installations.
