Metrics-Driven Metrics

Metrics-Driven Metrics
“You can measure almost anything,
but you cannot pay attention to
everything”

Metrics-Driven Metrics
“Any situation where people
create their own dashboards
without structure, quickly starts to
look like the cockpit of a 747”

Metrics-Driven Metrics
The dashboard should be:
• Meaningful
• Iterative
• Accessible

Metrics-Driven Metrics
The dashboard should reflect
your:
• Roadmap
• Highest Risk
• Most uncertain metrics

Shared Language
“Even the best metrics driven
development fails easily, when it’s
only built for yourself”

Shared Language
Implementation:
• Identify your impacted groups
• Identify the most effective
tools for each group
• Enable automation
