Emergency changes. These are changes that must be implemented as soon as possible; for example, to resolve an incident or implement a security patch. Emergency changes are not typically included in a change schedule, and the process for assessment and authorization is expedited to ensure they can be implemented quickly. As far as possible, emergency changes should be subject to the same testing, assessment, and authorization as normal changes, but it may be acceptable to defer some documentation until after the change has been implemented, and sometimes it will be necessary to implement the change with less testing due to time constraints. There may also be a separate change authority for emergency changes, typically including a small number of senior managers who understand the business risks involved.”

Achieve its goals in delivering quality and cost effective services

Meet the needs of its customers

Satisfy the requirements of its stakeholders

It is important to understand the difference in these terms not just for clarity, but because outputs are much easier to measure than outcomes.

Outputs are nearly always quantitative, with data available to show whether these have been delivered. Outputs are easy to report on and to validate. There is no grey area.

Outcomes are more challenging to verify because they are both qualitative and quantitative. Whether your outcomes have been achieved will rely, to a great extent, on the perception of the people who receive the service. Perceptions are not easy to measure or report on, but it is essential you find a way to do so.
