We report on an evaluation of the Customer Journey Modelling Language (CJML) for documenting and visualizing a service process from the customer's perspective. The target group is employees in service organizations. We present a modelling toolkit and a scenario-based procedure that was used during the experiment with 48 target users. The purpose was to assess the applicability of CJML when introduced...
Domain specific languages (DSLs) ease the adoption of formal specification in industry. They allow developers to describe their specification models in concepts of their domain. However, DSLs evolve over time, causing specification models to have to co-evolve to reflect the evolution in the DSL. The maintenance overhead introduced by these, often manual, changes to specification models threatens to...
Requirements engineering is a most critical activity in the engineering process of complex cyber-physical systems. To avoid the ambiguity of natural or semi-formal languages, to provide tool support for engineering activities all along a system lifecycle (from scoping studies to system operation, maintenance), EDF has developed FORM-L, a formal constraints-based language for the modelling of assumptions,...
This mini-tutorial highlights and conveys key practices in Requirements Engineering that can be applied in daily projects. It synthesizes the essence of six tutorials presented at the RE'13 Tutorial's sessions, and so promotes a great opportunity for a wider audience to learn from practice and have knowledge transfer. Besides that, this session is a great stimulus to increase the global synergy between...
As a new field of study, software engineering teaching and subjects vary from one textbook to another. Despite the fact that most of the books cover similar subjects, however, students' view of the subject is mixed. Some students have problems understanding the entire picture. Other students have problems connecting concepts with each other. In this research, an overall view of software engineering...
In view of variety and complexity of enterprise asset management system of coal preparation plant, the global analysis and design model is established. In addition, the modernized coal preparation plants are oriented towards interconnection and automation. It is of great necessity for the coal preparation plant to adopt the enterprise asset management. The enterprise asset management is a systematic...
The rapidly growing service-oriented economy has highlighted key challenges and opportunities in ICT-supported service and product lifecycle management. From a service consumer point of view there is no standardized way to locate, evaluate, negotiate and monitor services. Composition of third party services is fraught with uncertainty due to absence of definitive SLAs. Moreover, there is a lack of...
The design of extract transform loading (ETL) aggregation policy for data warehouse in LTS is introduced in the paper. Firstly, we analyze the characters of data storage in LTS, and according to the subject and logic model analyzed to LTS, estimate the data scale and classify the refresh frequency, then design the ETL aggregation policy, including aggregation tables and the process of aggregation...
This paper introduces the design of a template of architectural building blocks (ABBs) for the service component layer in the SOA solution stack (S3) reference architecture. SOA solution architects can use the industry practice-based template as a starting point to quickly configure, customize, and prototype their application-specific service component layer that provides code containers that implement...
