Problem Management′s mission is very simple and intuitive. It is about minizing the adverse effects on the business of Incidents and Problems caused by errors in the infrastructure. Simple example of an error in the infrastructure can be a router error which doesn′t transmit packages properly. If it′s kind of BGP router adverse effects on the business will be obviously huge. That′s why mission of Problem Management is to also proactively prevent the occurrence of Incidents, Problems and Errors - not just pasivly wait when something wrong is going on.

Proactive Problem Management is included in the Scope of Problem Management. It covers all activities which helps indentify and resolve problems before incidents come up. The activities can be divided into two groups:
Proactive Problem Management also targets preventive actions throughout supplying workarounds or procedures to people within the organization (or even 3rd parties) to prevent further incidents from occurring.

This method is very useful to preset which areas of the IT infrastructure are most painfull and which of them can cause the biggest pain when an error occur in a particular area. The pain value is nothing else then number of incidents multiplied by duration and severity multiplied by weighting factor. The rule is as follows:
Pain value = (No. of incidents) * (duration) * (severity) * (weighting factor)
In the Pain Value Analysis the calculation is made as shown (for severity it can be priority and in most cases it′s necessary to revers this e.g. if you have priority of 1-5 with 1 being the most severe impact then you will need to multiply this incidents by 5, low impact incidents i.e. severity 5 will need to be multiplied by 1)

In a grid environment like e.g. global organization having its departmets all over the world the core factor to do the business will be communication and data flows between departments. On the picture above you can see the most painful might be lack of connectivity in cellular phones and / or VOIP network. People in the organization probably use a lot of mobile phones and - because it is a global company that focuses on cost minimizing - Voice Over IP networks. Router are not so visible to end users that′s why many of them don′t even know there are such devices but anyway, they are still very crutial for the organization.
