Challenges in Applying Continuous Experimentation: A Practitioners' Perspective

Background: Applying Continuous Experimentation on a large scale is not easily achieved. Although the evolution within large tech organisations is well understood, we still lack a good understanding of how to transition a company towards applying more experiments. Objective: This study investigates how practitioners define, value and apply...

The effects of change decomposition on code review—a controlled experiment

Background: Code review is a cognitively demanding and time-consuming process. Previous qualitative studies hinted at how decomposing change sets into multiple yet internally coherent ones would improve the reviewing process. So far, literature provided no quantitative analysis of this hypothesis.<br/>Aims: (1) Quantitatively measure the effects...

A controlled experiment for program comprehension through trace visualization

Accepted version for publication in IEEE Transactions on Software Engineering. Software maintenance activities require a sufficient level of understanding of the software at hand that unfortunately is not always readily available. Execution trace visualization is a common approach in gaining this understanding, and among our own efforts in this...

Effort involved in single- and two-axis manual control systems

A theoretical and experimental program was conducted to study human response characteristics in a variety of single- and dual-axis control situations. The object was to build and support a human control effort model. The aspect of human controller's effort is indispensable for a complete description and prediction of human operator behavior and...
