iTop is an Open Source web application for the day to day operations of an IT environment. iTop was designed with the ITIL best practices in mind but does not dictate any specific process, the application is flexible enough to adapt to your processes whether you want rather informal and pragmatic processes or a strict ITIL aligned behaviour.
The belief behind iTop is that a CMDB must be an operational tool. The only way for a CMDB to be accurate and up to date is to be used day-to-day by the IT teams (support agents, IT engineers, etc.). Moreover, the more the CMDB is integrated with other IT tools (monitoring systems, reporting tools, automated inventory, etc.), the better.
