Delivery Performance

🇬🇧 🇧🇷

Delivery performance is defined by Forsgren et al. [1] as a combination of three metrics:

This definition seeks to avoid the problems of previous performance metrics, such as lines of code or velocity. These previous metrics often suffer from two drawbacks: focus on outputs rather than outcomes and focus on local results rather than in global ones. On the other hand, Forsgren et al. defined delivery performance in such way to focus on global outcome, ensuring teams aren’t pitted against each other.

Based on a survey with 27,000 responses in 2017, Forsgren et al. applied cluster analysis to these metrics and discovered three groups: high, medium, and low performers.

High performers:

Medium performers:

Low performers:

The research of Forsgren et al. has also discovered that the level of delivery performance correlates to the achievement of higher-level goals of the organizations, both for commercial and noncommercial purposes.

In our research, at ccsl/devops, we are not interested in distinguishing medium from lower performers. We are interested only in identifying high performers and non-high performers. But the above clusters are problematic for our purpose since there is a gap between high and medium performers cluster.

We circumvent this problem by considering an organization as high performer if i) it is within the boundaries limiting the cluster of high performers above defined or ii) it violates at most one high-performance threshold by only one point in the scale adopted for the metric.

Here follows the scale for each metric.
