AbstractSystems engineering (SE) is a general methodological approach that includes all relevant activities to design, develop and verify a system. This work was based on the need to enhance the integration of the customer needs into the design phases of SE. A joint methodology was proposed integrating the SE approach with the Design Thinking (DT). An analysis was conducted as part of a case study proposed by IBM Corporation for the development of a security system for a building. The results confirm that the insertion of the DT in the SE has a significant impact on the generation of concept solutions.

A Value

In recent years, crossover services have attracted wide attention as an emerging service mode in the modern service industry. Crossover services can offer values that cannot be provided by single-domain services, and they usually need to cross the boundaries of domains, organizations, and processes, which puts forward more challenges for requirements modeling and analysis under the crossover scenarios. Given the characteristics of crossover services, the authors propose a value-driven meta-model framework from multiple viewpoints to support the requirements analysis of crossover services, which consists of three parts: a value network, a goal network, and a service network. Based on the proposed meta-model framework, a value-driven crossover service modeling tool is developed to help requirements analysts in requirements analysis and design, and a case study is presented to illustrate the usage of the proposed approach. Finally, we evaluate our methods and tools using a controlled experiment, and the experimental results show the effectiveness of the approach.

Requirements elicited from requirements elicitation session with stakeholders are usually comes in bulk and it is impossible to execute them simultaneously. In addition, the requirements elicited are unfiltered and usually low quality including ambiguous, incomplete and unclear. The low quality of requirements are then refined in the next activity which is requirements analysis in requirements engineering. This paper aims to integrate requirements prioritization techniques focused on the factor of risk in requirements analysis since the early stage of requirements engineering. It is seems to have a little evidence on that requirements prioritization focus on the factor of risk in requirements based on our conducted literature review. This paper begins with elaboration on requirements prioritization, further to the aspects of requirements prioritization, criteria for best suited technique, a literature review on requirements prioritization techniques. We then proposed a framework for requirements analysis with the integration of requirements prioritization. A case study is elaborated for a better vision on the process of the proposed approach. Finally, this study is believed to produce a better quality of requirements from the requirements analysis process.

Requirements Modeling

Inconsistent specification are an inevitable intermediate product of a service requirements engineering process. In order to reduce requirements inconsistencies, we propose PASER, a Pattern-based Approach to Service Requirements analysis. The PASER approach first extracts the process information from service documents via natural language processing (NLP) techniques, then uses a requirements modeling language – Workflow-Patterns-based Process Language (WPPL) — to build the process model. Finally, through matching with workflow patterns, the inconsistencies in service requirements are identified and resolved by checking against a set of checking rules. We have conducted a preliminary experiment to evaluate it. An ATM service case study is presented as a running example to illustrate our approach.
