The change schedule is used to help plan changes, assist in communication, avoid conflicts, and assign resources. It can also be used after changes have been deployed to provide information needed for incident management, problem management, and improvement planning

Nonrepudiation provides an assurance that the sender of data is provided with proof of delivery and the recipient is provided with proof of the sender's identity, so neither can later deny having processed the data. Further, this concept can apply to any activity, not just the sending and receiving of data; in a more general sense, it is a mechanism to prove that an activity was performed and by whom. Nonrepudiation is typically comprised of authentication, auditing/logging, and cryptography services.

Each activity contributes to the value chain by transforming specific inputs into outputs. The inputs could be demand from outside the value chain, or outputs of other activities, while the transformation is facilitated by ITIL practices, undertaken using internal or third-party resources, processes, skills, and competencies.

• 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.”

The second step is to conduct an objective current-state assessment of existing services and service management practices. This should include consideration of the users’ perception of the value being received, along with a review of people’s competencies and skills, the processes and procedures involved, the capabilities of the available technological solutions and the prevailing organizational culture. The success of an improvement initiative depends on a clear and accurate understanding of the starting point and the required impact of the initiative.

For example, an organization can measure the current net promoter score (NPS) from a customer satisfaction survey, conduct a benchmark survey against its competitors or review findings of operational statistics or audit reports to understand its current state. If this step is skipped, the current state will not be understood and there will not be an objective baseline measurement against which improvement can be measured.
