• ROI definition
• Systems infrastructure sprawl
• Indicators of unmanaged capacity
• Scope and direction
• Variables and information gathering
• ROI models and cost benefit analysis
Return on Investment
One definition of ROI...
"For a given use of money in an enterprise,
the ROI (return on investment) is how much
profit or cost saving is realized. An ROI
calculation is sometimes used along with
other approaches to develop a business
case for a given proposal.”
Capacity Management ROI
Infrastructure Sprawl
• How much of it is being
used efficiently?
• How do you define
efficient, and does it
apply uniformly?
• Which systems will run
out of capacity?
• What visibility is
required to make it run
efficiently?
Capacity Management ROI
Indicators of unmanaged capacity
• Capacity related incidents
• Reactive mode of operation for capacity incidents
• Lack of visibility into system resource utilization
• Poor performance that is the norm
• No ownership of capacity concerns
• Using excessive hardware to ensure capacity
Capacity Management ROI
Scope to deliver high value returns

Capacity Management ROI
What variables are key to determine ROI?
• Resource utilizations
• Growth in resource utilizations
• Count of hardware/software assets
• Cost of hardware/software assets
• Maintenance cost for hardware
• Capacity related incidents
• Average cost of incidents
• Risk of capacity related incidents
• Capacity related labor costs

Summary and Final Thoughts
Justification for doing capacity management many times will
involve showing a return on investment. Doing this can be
difficult with so many variables involved.
We outlined some key variables that should be included in the
analysis, and presented two spreadsheet models that utilizes
those variables.
• Doing capacity management is worth the effort, and
demonstrating that argument with numbers can help to
show it quantitatively.
