An Approach for Selecting the Suitable Requirement Elicitation Technique

Requirements elicitation is an initial phase in software development. In this phase, requirements engineers gather the requirements of the software under development from users, stakeholders and customers. The techniques used for gathering requirements have a big influence on the quality of requirements and the success of project. Many requirements elicitation techniques (RET) such as: interview, prototype and observation can be used for requirements gathering process. However, one technique is not suitable for all different projects. Usually requirement engineers select the RET based on personal preferences and assumptions such as; this is the only technique which they know. However, this subjective decision can result in using inappropriate RET. Using unsuitable RET may decrease the quality of elicited requirements. Even though researchers have proposed many techniques for elicitation, one of the challenging issues is to choose the suitable RET for specific situations. The purpose of this paper is to help requirement engineers to choose suitable RET. To do that firstly, we identify factors that affect in selecting RET. Secondly, an approach to select suitable RET is proposed. Thirdly, a prototype is developed to help requirements engineers and to ease the process of selectingelicitation technique. Lastly, experts evaluate the proposed approach and the prototype.

Implementasi Aplikasi Pengukuran Kondisi Fisik Pemain Sepak Bola Berbasis Web Mobile

Penelitian dilakukan pada pemain sepak bola di Universitas Bina Darma mengenai kondisi fisiknya. Kondisi fisik merupakan unsur yang penting dan menjadi dasar dalam mengernbangkan teknik, taktik, maupun strategi dalam bermain sepakbola. Pemain Sepak Bola perlu adannya pengukuran kodisi fisik atlet guna meningkatkan potensi fugsional atlet dan mengembangkan kemanpuan biomotor kestandar yang paling tinggi. Pengukuran kondisi fisik atlet yaitu atlet Sepak Bola di Universitas Binadarma masing dilakukan secara manual yaitu ditulis dalam kertas untuk poin-poin yang diperoleh selama pengukuran kondisi fisik. Kondisi seperti ini akan memperlambat untuk mengetahui berapa biomotor hasil yang diperoleh dalam pengukuran kondisi fisik atlet, dan kesulitan untuk mengetahui histori biomotor hasil pengukuran kodisi fisik sebelumnya, apa mengalami penurunan atau kenaikan biomotornya. Solusi dari permasalah tersebut dengan mengembangan sistem dalam mengukur kodisi fisik atlet Sepak Bola dalam bentuk Aplikasi Pengukuran Kondisi Fisik berbasis web mobile. Metode pangambangan aplikasi yang digunakan adalah metode waterfall dengan beberpa tahapan antara lain communication (project initiation & requirements gathering), planning (estimating, scheduling, tracking), modeling (analysis & design), construction (code & test), deployment (delivery, support, feedback). Tujuan dari penelitian ini untuk mempermudah dan mempercepat dalam pengukuran kondisi fisik atlet.

WLCG Authorisation from X.509 to Tokens

The WLCG Authorisation Working Group was formed in July 2017 with the objective to understand and meet the needs of a future-looking Authentication and Authorisation Infrastructure (AAI) for WLCG experiments. Much has changed since the early 2000s when X.509 certificates presented the most suitable choice for authorisation within the grid; progress in token based authorisation and identity federation has provided an interesting alternative with notable advantages in usability and compatibility with external (commercial) partners. The need for interoperability in this new model is paramount as infrastructures and research communities become increasingly interdependent. Over the past two years, the working group has made significant steps towards identifying a system to meet the technical needs highlighted by the community during staged requirements gathering activities. Enhancement work has been possible thanks to externally funded projects, allowing existing AAI solutions to be adapted to our needs. A cornerstone of the infrastructure is the reliance on a common token schema in line with evolving standards and best practices, allowing for maximum compatibility and easy cooperation with peer infrastructures and services. We present the work of the group and an analysis of the anticipated changes in authorisation model by moving from X.509 to token based authorisation. A concrete example of token integration in Rucio is presented.
