How to Evaluate & Prioritize Automation Use Cases

Before we dive into each use case, it’s important to understand how best to evaluate and prioritize where to start with network automation based on the value use cases would deliver to your organization.

How to Measure Automation Value

1. Acceleration: The business benefit of reducing intervals.
2. Productivity: Increased work capacity per engineer or team.
3. Efficiency: Percent reduction in time/effort.

The scope of this eBook presents a simple model to calculate value (improvement x task volume) for each use case with a handful of estimated metrics to start building your business case and understanding the value automation can deliver.

How to Calculate Automation Value

Task Time: The amount of time it takes to execute the specific task.

End-to-End Time: The amount of time it takes to complete the full process of a specific task from ticket creation to ticket closure, such as data gathering, pre-checks, the change itself, post-checks, closing the ticket, and communicating the change via messaging systems.

Automation Value Calculations

End-to-End Time Saved =
(Manual End-to-End Duration – Automated End-to-End Duration) x (Devices x Frequency Per Device)

Human Task Time Saved =
(Human Manual Time – Automated Time) x (Device Count x Frequency Per Device)

Total Automation Benefit =
