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