Establishing and Maintaining Web Performance Measures
"You can't fix every problem...instead, focus on what you need to fix, and know what you can fix." - Ernie Bonacquisti, Global Technology Manager, Deloitte
Are you struggling with how to develop and evaluate performance measurements for the modern web experience? You are not alone -- it's a challenge facing even the most successful, forward thinking companies. Deloitte's Global Technology Manager Ernie Bonacquisti shared successful techniques they implemented to establish and maintain web performance metrics.
When establishing web performance metrics, it's important to understand that every measurement put out there may be subject to heavy scrutiny. The foundation of performance measurement is rock solid data -- data that has an identifiable source and clear significance to consumers. This data allows companies to create, establish and meet real world SLA's. Maintaining rock solid data requires using the most up-to-date best practices, the latest version of code.
Deloitte's rock solid data is reported internally on two levels, or views -- a management overview and an in-depth technical details view. The four metrics used to measure performance that are highlighted in these reports are:
1. First Byte - How well your server responds
2. DOM Interactive - How soon a user can interact with the application
3. Page Load Time - Determines page size, as well as asset prioritization and functionality
