WISB WIRI and CMDB Oh My

Do you really know what’s going on with your network assets?
When you make a planned change how can you be sure it was successful?
What when something breaks unexpectedly – maybe someone made an unplanned change or didn’t communicate this to the team?

WISB and WIRI models can help detect changes by performing regular queries against your CMDB. What does this all mean? How does it work.

What

What

Change
Management
Data
Base

It’s quite simple when you think about it. But there will be some work required to set it all up and fine tune the reporting. Getting access to the data and making sense of it is another matter. ITIL describes this process as DIKW. The idea is that you can’t make a Wise decision without the Knowledge that comes from Information derived from Data.
