• Estrategia del Servicio

1. What is a "Change"? The addition, modification or removal of anything that could have an effect on IT services. The scope should include all IT services, configuration items, processes, documentation etc. 2. Why do we need a Change management in an organization? The purpose of change management is to: Respond to the customer’s changing business requirements while maximizing value and reducing incidents, disruption and rework. Respond to the business and IT requests for change that will align the services with the business needs. The objective of the change management process is to ensure that changes are recorded and then evaluated,authorised, prioritized, planned, tested, implemented, documented and reviewed in a controlled manner and take necessary corrective action. 3. Importance of Change Management Team in an Organization? Reduction in the number of disruptions to services defects and rework caused by inaccurate specification, poor or incomplete impact assessment of changes. Reduction in the number of unauthorized changes. Reduction in the number and percentage of unplanned changes and emergency fixes. Change success rate (percentage of changes deemed successful at review/number of RFCs approved). Reduction in the number of changes where remediation is invoked. Reduction in the number of failed changes. 4. What is ITIL? Information technology infrastructure library. It is the set of best practices being followed in the organization. 5.

Tables all Request for Changes (RFCs) for a Change Advisory Board (CAB) meeting, issues an agenda and circulates all requests for changes to Change Advisory Board members in advance of meetings to allow prior consideration. Decides which CAB members will come to which meetings, who get specific RFCs depending on the nature of the RFC. Convenes urgent CAB or ECAB meetings for all urgent RFCs. Chairs all CAB and ECAB meetings. Authorizes acceptable changes, either alone or after a CAB or ECAB has taken place. Issues change schedules Liaises with all necessary parties to coordinate change building, testing and implementation, in accordance with schedules Updates the change log with all progress that occurs, including any actions to correct problems and/or to take opportunities to improve service quality. Reviews all implemented changes to ensure that they have met their objectives; refers back any that have been backed out of have failed. Reviews all outstanding RFCs Analyses change records to determine any trends Closes RFCs Produces regular management reports 15. Risk indicators of poor change management? Unauthorized changes.
