Change is inevitable, and the rate of change in technology is increasing. Businesses, business processes and business models constantly have to adapt to the economic climate, competitive pressures, and the opportunity to create through change and innovation. Change management, as a discipline in distributed computing is somewhat lacking. Yet, change management for IT operations is critical to improving availability, performance and throughput. Strong change management is the backbone for IT operations. Strong IT change management enables an enterprise to change the business process and business model that are so intertwined and dependent on the technology. Any business process change is likely to require significant technology changes. Thus, the IT operations group must step in and address these changes with the business units and applications development organization. Strong operational change management reduces errors, as well as planned and unplanned downtime.
The goal of the Change Management process is to ensure that standardized methods and procedures are used for efficient and prompt handling of all Changes, in order to minimize the impact of Change-related Incidents upon service quality, and consequently to improve the day-to-day operations of the organization.
Activities undertaken will involve:
**Urgent changes follow the same steps, but usually in a different order. The CAB/EC approves an urgent change immediately and the building, testing and implementation is done before the paperwork. But DON’T FORGET THE DOCUMENTATION!
Change Advisory Board (CAB): A dynamic group of people (depending on the change) that approve Changes with medium to high priority, risk and impact.
CAB/EC (Change Advisory Board/Emergency Committee): CAB Emergency committee approves and authorizes changes with high urgency, risk and impact.
Change Manager: Responsible for the Change Management process and authorizes all changes
Change models: Some organizations use change models prior to implementation to estimate the impact of the change. Change Management and Capacity management work together on this.
Forward Schedule of Changes (FSC): The FSC contains details of all approved changes and their proposed implementation date.
Projected Service Availability (PSA): The PSA contains details of changes to agreed SLAs and service availability because of the current FSC.
Requests for Change: Every change to the IT Infrastructure has to go through Change Management. A Request for Change (RFC) is formally issued for every change request.
A controlled way of managing changes in the IT infrastructure with minimal –or deliberately taken – risk to the service levels.
