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

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.
