Abstract
Just-in-time (JIT) approaches have been suggested
for managing non-functional requirements in agile projects.
However, many non-functional requirements cannot be raised
and met on the spot. In this position paper, we argue that
effective JIT engineering of quality requirements depends on
a solid foundation of long-term knowledge about all relevant
quality requirements. We present two examples from projects
related to safety and security and show that not all aspects
of these quality requirements can be invented and changed
just in time. Further, managing, for example, operationalization
of quality requirements just in time depends on sufficient
understanding of (i) customer value and (ii) the system under
construction that must be shared by the engineering team. If a
Learning Software Organization (LSO) intends to increase agility
and speed up system development, it needs a holistic concept
for managing this knowledge. We propose that a knowledgemanagement
framework can facilitate JIT-RE by structuring,
representing, and allowing updates of long-term knowledge about
quality requirements. Such a knowledge-management framework
should allow to map user value to system requirements and have
important properties to allow JIT RE and sustainable evolution.
