10 IT Assumptions You Need to Eliminate to Ensure Successful Change and Configuration Management
Processes, workflows, best practices, and new developments have become ingrained for many to be the salvation that IT operations needs to stay ahead of complexity that turns the data center on its head. Check out these 10 assumptions that need to be eliminated to get things done right in IT operations today.
1. No Process Shortcuts in Change and Configuration ManagementDon't enforce a change and configuration management process that does not have legitimate shortcuts.
2. Approved Changes Are Perfectly ImplementedDon't assume that a change that was implemented is exactly the same as the change that was approved.
3. Pad the Project Plan with Extra TimeStop cushioning your project plan with extra time for environment setup and release stabilization. This just means giving up to the bad practices that can be simply eliminated.
4. Not Working Because Pre-production is Low on ResourcesStop blaming the failures of testing on the fact that pre-production is smaller with less resources than production.
5. When an Incident Happens, Just Ask the Team What they DidGet out of phone tagging across operational teams with a question "did anyone change anything?" This is not the most efficient way for incident investigation anymore.
6. Implement the Latest Technology DevelopmentDon't expect new technologies to be a silver bullet. Neither virtualization nor cloud completely solve the change and configuration management challenge. They change the focus of the challenge not eliminate it.
7. People Should Keep Track of Their Own ChangesRelying on your people is very important. However don't rely on them, when they claim that they know exactly what they changed. This falls apart in a complex and dynamic environment, since so many things are happening, people don't always keep track of everything.
8. The CMDB is Best for Handling Change and Configuration ManagementAccept the truth that final deployment of your CMDB project is not the ultimate end of change and configuration management implementation. CMDB is just a bird-eye view of your assets. Additional intelligent and granular analysis is required to take on full control of your environment.
9. Rely on Your Change Management WorkflowDon't assume your environment's appearance is as a result of your change management workflow. Environments drift in spite of any defined workflows.
10. Depend on Rare Failover TestsDon't leave your disaster recovery environment to depend on rare failover tests. If the DR environment is not aligned with your production when it is needed it turns into a waste of money and provides false security.
