UITS units involved in the change, or supporting the change, must agree to the readiness and timing of the change. If any unit does not agree, or is not ready, then the implementation needs to be renegotiated. The degree and lead-time associated with user notification is dependent on the nature and complexity of the change. Changes involving conversions or change in procedure for the user will involve more notification, support and training than other types of change. It is better to notify users of changes and receive false reports of problems blamed on the change, than it is not to notify users and have a single problem associated with the change.
UITS staff are users too.
All principles and procedures applying to end-users apply to changes that can potentially impact UITS staff as well. One set of detailed procedures will not necessarily fit all types of change. It may be entirely appropriate for UITS to follow a single set of procedures to address changes, but it does not necessarily follow that all changes are incorporated into a single procedure. All units within UITS must document and implement a procedure that addresses change. The scheduled implementation date and time should be such as to minimize downtime and impact for the users.
