Alferez et al. (2014) presented a metric-based comparative study of existing scenario-based SPL requirements approaches in order to understand how they address modularity, stability and expressiveness.
From these, the newest paper (Alferez et al. (2014)) presents a metric-based evaluation aimed at assessing quality attributes such as modularity, stability and expressiveness of SPL requirements approaches like the PLUSS (Eriksson et al. 2005).
Seemingly contradictory regulations at the federal, state, and local levels can be resolved by using the "greatest requirement" approach to facilitate flexibility in the long-term use of an ASC.
The import allowance requirement approach has its own problems, however.
Despite these three problems with the import-allowance-requirement approach, note that it was a key part of the Lieberman-Warner Climate Security Act in the U.S. Senate in 2008, and may re-appear when serious debate commences in the Senate on climate legislation later this year.
In a recent work, Oliveira et al. (2014) evaluated their requirements engineering approach, the Feature-Driven Requirements Engineering approach (FeDRE), through a case study for developing an SPL of mobile applications for emergency notifications.
Clients still seem pretty complacent, but now that regulators are imposing more reasonable capital requirements, the approach seems to be coming apart.
It is unlikely that a similar cross-national perspective on the teaching workforce in primary schools would reveal such divergent approaches towards qualification requirements, training approaches, professional profiles, and recruitment and support systems.
The requirements engineering approach is grounded in the theoretical framework of C K theory.
