Archibus should allow the creation of status in the configuration and a way to map process (approve, estimate, plan) to status. We found out that the number of status is limited if you want to track specific questions such as:
- differentiate between request that are waiting for planning that the one being planned
- differentiate between request waiting to be processed by a craft and a request being processed, a request processed but not verified by the supervisor

Also we have custom needs for billing and there is no way to create a status for this.
