Service Evaluation in SOA: Toward Business/IT Alignment

Alignment between Business Requirement, Business Process, and Software System: A Systematic Literature Review

“…Indeed, they identify the business requirements using the goal-oriented modeling notation i * and define them by using the UML activity and class diagrams. (iv) Jing Wang et al [53] use a quantitative evaluation method to measure the degree and evaluate how the services in SOA can contribute to the satisfaction of the business requirements. (v) Galster and Bucherer [57] align high-level business goal with services using the BGSC (Business-Goal-Service-Capability) Graph.…”

“…e majority of studies that deal with the topic of alignment between business requirement and software system consider the linking level. us, there is just one paper [53] that proposes the evaluation step. However, there is no paper that proposes a method to correct the misalignment detected.…”

“…2009 [53] Development of a web application to calculate two measurements of mean and variance; the objective is to evaluate the contribution of services to the business requirements S48 2008 [63] Proposition of an approach of checking alignment by using consistency relationships S59 2005 [74] Proposition of ten criteria and ten metrics according to four factors; the objective is to evaluate the fit between business and system sides focusing on the phase of linking models (by transformation or generation of models, by proposing some mapping, or consistency rules etc.). In our future work, we aim to propose an exhaustive approach that deals with the phases of alignment between each of the two levels.…”

The Determination of Service Couplings for Non-disruptive Systems

“…There are a number of researches in the literature that have proposed techniques to determine the quality of a system design (Yang et al, 2005;Rich et al, 2012;Wang et al, 2009;Gui and Scott, 2006;Allen and Khoshgoftaar, 1999). Among the proposed techniques, system component coupling or dependency is one of the most widely adopted techniques (Yang et al, 2007).…”

“…In a service-oriented environment, any service interruption may cause some loss in business due to the business disruption. Therefore, for business continuity, a highly available system should consider providing at least one alternative service for each critical one (Wang et al, 2009). That means when a critical service becomes unavailable, there should be some other service that can provide the equivalent functionality.…”
