Applying Software Defect Estimations: Using a Risk Matrix for Tuning Test Effort

TL;DR

This paper introduces a Test Risk Matrix that visualizes defect estimation data, aiding decision-making and risk assessment in large-scale software development.

Contribution

It presents a novel application of a risk matrix for tuning test effort based on defect estimations, enhancing management tools.

Findings

Proven effectiveness in multiple large-scale releases

Clarifies risks in development planning meetings

Improves decision-making regarding test activities

Abstract

Applying software defect esimation techniques and presenting this information in a compact and impactful decision table can clearly illustrate to collaborative groups how critical this position is in the overall development cycle. The Test Risk Matrix described here has proven to be a valuable addition to the management tools and approaches used in developing large scale software on several releases. Use of this matrix in development planning meetings can clarify the attendant risks and possible consequences of carrying out or bypassing specific test activities.
