ARES: An Agile Requirements Specification Process for Regulated Environments

Agile methods have provided significant contributions to Software Engineering. This work presents a new process for Software Requirements Specification, integrating Agile Properties and regulated environments, such as aviation, medical, nuclear and automotive, among others. The Software in Regulated Environments (SRE) involves plan-driven methods with needed documentation to ensure safety, reliability, security, and discipline. This paper proposes a balance between agile and plan-driven methods. We define a new process, which explores and investigates the usage of agile methods in SRE. The scope of this paper is Requirements Engineering, which is considered as a set of activities involved in the management, elicitation, documentation, and maintenance of requirements. The Adile Requirements Specification (ARES) process contains four methods, 13 activities, and some required artifacts to ensure compliance with the following six relevant Software Standards for regulated environments: RTCA DO-178C, IEC 62304:2015, ECSS-E-ST-40C, IEC 61508-3, ISO/IEC/IEEE 12207, and IAEA SSG-39. The process evaluation was performed using two experiments: a Cockpit Display System (CDS) and a Healthcare Information System (HIS). These experiments were measured with appropriate metrics to ensure improvements in Software Requirements Specification and traceability among artifacts. The experimental results revealed that the ARES process works better than the original Scrum for Software in Regulated Environments. The ARES process can also be integrated with traditional software life cycles (Waterfall, V, and Incremental and Iterative), when applied in the Requirements Engineering phase.

Evaluasi Usability Test e-Repository dengan menggunakan Metode Nielsen’s Attributtes of Usability (NAU)

In meeting good software standards, testing of software quality is required. Usability is an aspect of software The purpose of this study is to obtain the usability test evaluation results on AMIK Indonesia's e-Repository with the efficiency and error factor based on the Nielsen's Attributes of Usability (NAU) questionnaire method, so that later it will be made as a suggestion and recommendation for the development of AMIK Indonesia's e-Repository based on the results The test is to improve the quality of the website in the usability aspect. This research method is divided into 4 stages consisting of activities in it, consisting of; 1) Initiation, 2) Pre-User Testing, 3) Pre-User Testing, and 4) Post User Testing. The sample of users was 22 students consisting of Class 2015, 2016, 2017 and 2018 who were active students of AMIK Indonesia. From the results of the achievement of research conducted that the usability test with Nielsen's Attributes of Usability (NAU) model can be applied in finding the quality level of a website. From the test results, the level of success in the UT-7, UT-8, and UT-10 tests with achievements of less than 80% of respondents failed to answer. For success rates above 80% on testing UT-1, UT-2, UT-3, UT-4, UT-5, UT-6, and UT-9. The results of the analysis carried out very satisfying interpretation of 14, Satisfied 1, Satisfied 2, Not Satisfied 1. As for the interpretation of dissatisfaction with questions with the ER14 code and quite satisfied with the ER12 and ER13 codes which are all three dimensions of error.Keywords:Usability, Evaluation, e-Repository, Website Quality, Nielsen's Attributes of Usability (NAU).

Designing web-scale discovery systems using the VuFind open source software

Purpose This paper aims to provide an overview of the emergence of resource discovery systems and services along with their advantages and best practices including current landscapes. It reports the development of a resource discovery system by using the “VuFind” software and describes other technological tools, software, standards and protocols required for the development of the prototype. Design/methodology/approach This paper describes the process of integrating VuFind (resource discovery tool) with Koha (integrated library system), DSpace (repository software) and Apache Tika (as full-text extractor for full-text searching), etc. Findings The proposed model performs like other existing commercial and open source Web-scale resource discovery systems and is capable of harvesting resources from different subscribed or external sources replacing a library’s OPAC. Originality/value This discovery system is an important add-on to designing a one-stop access in place of the existing retrieval silos in libraries. This system is capable of indexing a variety of content within and beyond library collections. This work may help library professionals and administrators in designing their discovery system, as well as vendors to improve their products, to provide different library-friendly services.

The Cloud Feedback Model Intercomparison Project Observational Simulator Package: Version 2

The Cloud Feedback Model Intercomparison Project Observational Simulator Package (COSP) gathers together a collection of observation proxies or “satellite simulators” that translate model-simulated cloud properties to synthetic observations as would be obtained by a range of satellite observing systems. This paper introduces COSP2, an evolution focusing on more explicit and consistent separation between host model, coupling infrastructure, and individual observing proxies. Revisions also enhance flexibility by allowing for model-specific representation of sub-grid-scale cloudiness, provide greater clarity by clearly separating tasks, support greater use of shared code and data including shared inputs across simulators, and follow more uniform software standards to simplify implementation across a wide range of platforms. The complete package including a testing suite is freely available.
