Developer Evaluation: Assessing the Quality of Outsourced Personnel
Outsource team KPIs help businesses evaluate the performance of outsourced teams based on velocity, bug rate, and delivery rate. This article guides you through building KPIs for outsource teams and provides a free template to measure project performance.
Building a clear KPI system for outsourced teams is an essential step in helping businesses manage outsourced performance. Many projects encounter delays, high bug volume, or inconsistent delivery simply because there were no proper KPIs established from the start. When businesses can track velocity, bug rate, and delivery rate with concrete data, performance evaluation becomes transparent, less subjective, and more optimized for overall team productivity.
This article explains in detail the three most important KPI groups for outsourced teams and provides a free template businesses can apply immediately.

Velocity is a core metric when evaluating outsource team performance in Agile. It reflects the amount of work completed in each sprint and shows the team’s ability to maintain throughput over time. When velocity is stable, businesses can predict release timelines and estimate required resources for the next sprint.
If velocity fluctuates significantly, it signals issues with skills, processes, or internal coordination. Therefore, velocity is considered one of the most important KPIs for outsource teams to control quality and speed.

Besides speed, output quality is a crucial measure of outsourced team performance. Bug rate indicates the number of defects found per feature or per sprint and reflects the accuracy, review process, and technical skills of the team.
When bug rate is too high, the project tends to spend more time fixing issues than building new features, leading to delayed releases, increased costs, and worse user experience. Conversely, a team with a low bug rate demonstrates that testing, review, and coding processes are following best practices, enabling stable development progress and saving time for the business.

Delivery rate shows the percentage of tasks delivered on time by the outsourced team. If the team completes many tasks but does not deliver them by the deadline, the project still risks missing go-live dates. Thus, delivery rate is a KPI that helps businesses measure team commitment, ability to maintain timelines, and adherence to processes.
A team with a stable delivery rate usually demonstrates strong responsibility, good communication, and a clear understanding of project priorities. This is a crucial factor in any evaluation of outsource team KPIs, especially for projects requiring a well-defined roadmap.

Below is a sample template to help businesses evaluate outsource team performance based on three KPI groups: velocity, bug rate, and delivery rate.
Outsource Team KPI Template:
| KPI | Formula | Evaluation Purpose |
|---|---|---|
| Velocity | Story points / sprint | Measures completion speed |
| Bug rate | Number of bugs / task or sprint | Measures product quality |
| Delivery rate | Tasks delivered on time / total tasks | Measures commitment & discipline |
Businesses can expand this template based on project scale or add additional KPIs such as code quality, response time, or number of reopened bugs.
