Taxonomy of Mobility-Related Requirements

The need for mobile information systems is growing, yet the challenge of requirements engineering for this particular type of systems has not been much explored. While there are several proposals for taxonomies of quality requirements, mobility has not been investigated as a potential category in such taxonomies. This paper proposes a taxonomy of mobility-related requirements. Structurally, the taxonomy is much inspired by similar taxonomies for safety and security-related requirements. However, the differences between mobility and safety/security implies that other sources also had to be taken into account, discussing the concept of mobility from an IS perspective. The proposed taxonomy may be used as a starting point for guidelines on how to write mobility-related requirements, as well as a basis for completeness checklists.
