Diploma thesis is dedicated to the analysis of threats and risks related with document management in a real enterprise -- big telco company. For document management company utilizes a complex solution called application DMS which is implemented on IBM FileNet P8 platform. In my work I will concentrate on risks linked with operation of DMS application.

These problems will be the basis for identification of the risks for the company emerging from the operation of DMS application. Subsequently I will evaluate risks and propose solutions to handle or avoid these risks. I will put proposed solutions into the sequence, in which they should be implemented while considering nature of the risk and financial demands of the proposed solution. Contributions of my work are list of identified risks and list of solutions which both can be used for assigning priorities of the change requests carried out in 2013 and possibly during discussions about budget increase for the DMS application operation.
