A metric is an objective measure for assessing performance against defined success criteria. It helps engineering managers gauge progress, plan strategically, and identify areas for improvement. section 1.2
Useful measures can cover several connected dimensions of team success:
- Business value, such as customer satisfaction, retention, and customer feedback. section 1.2.1
- Delivery and execution, including milestone timing, team velocity, and quality standards. section 9.2.6
- Collaboration and development, including communication, knowledge sharing, innovation, and upskilling. section 9.2.6
- Operational outcomes, resource use, and return on investment. section 1.2 section 9.2.6
Set a measurable project goal
A product launch that raises customer satisfaction by 20% and reduces escalations by 30% meets its success criteria when those measures were agreed during project initiation. Analyze changes carefully: a metric alone may not identify their cause. section 1.2.1
For technical work, measures can help make trade-offs clear to nontechnical partners. Reliability, service-level agreement violations, customer impact, and short- versus long-term costs can help frame a technical-debt decision. section 9.3.4
