Goal – Primary Objective • To ensure that standardised methods and procedures are used for efficient and prompt handling of all Changes, in order to minimise the adverse impact of any Change-related incidents upon service quality
Responsibilities • Raising and recording Changes • Assessing the impact, cost, benefit, resource requirements and risk of proposed Changes • Developing business justification and obtaining approval • Managing and coordinating Change implementations • Monitoring and reporting on the implementation • Reviewing and closing Requests for Change (RFC)
Why Change Management • Ensure Standard methods used for all changes • Facilitate prompt handling of changes • Keep a balance between the need for change and the potential detrimental impact of change
Types of Change • Basic Change - Priority: Based on Impact+Urgency High, Medium, Low … (Urgent?) - Category: Based on business impact Minor, Significant, Major • Urgent Change - A change that needs to be implemented more quickly • Standard Change - An accepted solution to an identifiable and relatively common set of requirements (e.g. set up of User profile, Password reset)

Considerations • Change Advisory Board (CAB) - RFC are circulated to selected members depending on Change Category (Minor, Major, Significant) - Mandatory assessment of RFC - Optional attendance of CAB meeting - Meetings held on a regular basis • CAB / Emergency Committee (CAB/EC) - Responsibility for impact assessment of urgent changes • Forward Schedule of Changes (FSC) • Projected Service Availability (PSA) based on FSC
Benefits • Increased visibility and communication of changes to both business and service support staff • Reduced adverse impact of change from improved business, technical impact and risk assessment • Improved productivity of Users through less disruption and higher quality of service • Better assessment of the cost of proposed changes • Greater ability to absorb a large volume of change
CH Exam Tips • Basic and Urgent Change Control Process • Change is associated with RISK • CAB Members • Problem Manager • Change Manager • Customer Representatives

A If it is urgent, as soon as the Request for Change has been classified B As soon as there is a back-out plan for the change C As soon as the impact analysis has been discussed by the members of the Change Advisory Board D As soon as the Request for Change has been formally authorised
