A Few Questions
1. Who has created or viewed more than 10 Visio diagrams this
year?
2. Who typically documents inventory data in Excel and
diagrams in Visio?
3. Who has had a Visio training course in the last 3 years?

Managing Change…
Managing change in critical IT Infrastructure
Managing – culture, processes and support systems
Change – systems, projects / tasks, operations
Critical – risk to business functions / processes
IT Infrastructure - servers, software, power, cabling

Infrastructure Change Support
It’s common sense that you should know what is in your IT
infrastructure, how it is configured, how it works
So planning changes is easy
Fault diagnosis is quick
To optimise infrastructure resources
To check with other information

But…. Does the CMS/CMDB
• Make it easy to find equipment and connectivity?
• Produce the project and operational diagrams we need?
• Identify spare and underused racks and infrastructure?
• Provide appropriate lists and diagrams to suit projects/ops?
• Have a user interface that makes it easy for users?
• What is practical and realistic?

Avoiding Excel & Visio Chaos
• Infrastructure is complex
• The risk of disruption increases with complexity
How do you manage complexity?
![Page 13: Managing Change in Critical IT Infrastructure - Square Mile Systems](https://reader030.vdocuments.mx/reader030/viewer/2022021008/6203a2f1da24ad121e4bb52e/html5/thumbnails/13.jpg)
Avoiding Excel and Visio Chaos
![Page 14: Managing Change in Critical IT Infrastructure - Square Mile Systems](https://reader030.vdocuments.mx/reader030/viewer/2022021008/6203a2f1da24ad121e4bb52e/html5/thumbnails/14.jpg)
Why Infrastructure Configuration Management?
• Time
– Reducing project and change delivery times
– Identifying faults and recovery risks
– Providing management information / evidence of control
• Cost
– Reduce workload on project teams – site survey, discovery
– Identify consolidation / resource utilisation opportunities
– Operational management change/incident/reporting/billing
• Risk
– Individual / team overload due to experience/skill set
– Identify change impacts / risks
– Communication across teams

But..
Infrastructure complexity
– Scale and scope – local, end to end
– Understanding risk and dependencies
– Maintaining diagrams – network, power, application, space
Duplication and overlap of infrastructure data
– Multiple toolsets, spread sheets and diagrams
– Distraction - autodiscovery/CMDB/integration
How to change
– Knowing the starting point – process, data, benefits
– Reduce data sets and maintenance effort
– Change skills, work process and culture

Why is Infrastructure CM Different?
• Standard naming and conventions
– Fixed infrastructure
– Active components
– Connectivity power, network, SAN
• Multiple outputs from a few sources
– Rack and floor management
– Capacity management space, power, connectivity
– Visual views, rack, network, power, system
– Inventory and asset management
– Service and system mapping
• Reduce multiple data sets to a reduced set
– Project, operations, risk, asset, audit, platforms

Q. When would a rack diagram be updated with the position of a new server?
Q. When would patching records be updated for it’s network connections?
Q. Who would update the documentation?

Implementing Infrastructure CM
• You could define your own approach but will be limited by
– Authority
– Experience
– Technical qualifications
– Best communicators available
– Management information
• So you should adopt a pragmatic approach
– Look for quick wins that all understand
– The first steps are often setting standards – so they’ll take longer
– Create a POC that shows the benefits as soon as possible
– Selective use of advisors, training, workshops, tasks
– It doesn’t have to be perfect, just better!
