i-doit is a Web-based IT documentation and CMDB. It documents IT-systems and their changes, defines emergency plans, displays vital information, and helps to ensure a stable and efficient IT operation. All information can be organized (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, and 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.
