Learnability for Reuse

Learnability 2.3.2 is defined as the attributes of software that bear on the users' efforts for learning its application.

Learnability for Reuse is a special case of the quality criterium Learnability 2.3.2 and not specifically mentioned in the ISO 9126-3 standard. It can be understood as learnability of software for a software engineer or developer with the purpose of integrating it in new systems, e.g., learnability of libraries and components.

Hence, internal learnability metrics assess how long software engineers or developers take to learn how to use particular functions, and the effectiveness of documentation. Learnability is strongly related to understandability, and understandability measurements can be indicators of the learnability potential of the software.
