i-doit is a web based IT documentation and CMDB. i-doit documents IT-systems and their changes, defines emergency plans, displays vital information and helps to ensure a stable and efficient IT operation: The technical documentation: This means that all information can be organised (details flexibly adjusted), stored and maintained in one place. This allows simple Helpdesk, Support and Planning functions and provides the basis for quality assurance and certification. i-doit allows services to be documented as a logical grouping of objects placed in relation to each other. This provides the basis for (ITIL) processes such as Change and Problem Management, helps to control and manage the SLA (Service Level Agreement) or the communication with users. Its interfaces to other ITSM applications (like Nagios, Request Tracker etc.) allow the entering of data only once in the ITSM environment. i-doit maintains one holistic view of the operational situation.
