Comparative Study on Agile software development methodologies

Today-s business environment is very much dynamic, and organisations are constantly changing their software requirements to adjust with new environment. They also demand for fast delivery of software products as well as for accepting changing requirements. In this aspect, traditional plan-driven developments fail to meet up these requirements. Though traditional software development methodologies, such as life cycle-based structured and object oriented approaches, continue to dominate the systems development few decades and much research has done in traditional methodologies, Agile software development brings its own set of novel challenges that must be addressed to satisfy the customer through early and continuous delivery of the valuable software. It is a set of software development methods based on iterative and incremental development process, where requirements and development evolve through collaboration between self-organizing, cross-functional teams that allows rapid delivery of high quality software to meet customer needs and also accommodate changes in the requirements. In this paper, we significantly identify and describe the major factors, that Agile development approach improves software development process to meet the rapid changing business environments. We also provide a brief comparison of agile development methodologies with traditional systems development methodologies, and discuss current state of adopting agile methodologies. We speculate that from the need to satisfy the customer through early and continuous delivery of the valuable software, Agile software development is emerged as an alternative to traditional plan-based software development methods. The purpose of this paper, is to provide an in-depth understanding, the major benefits of agile development approach to software development industry, as well as provide a comparison study report of ASDM over TSDM.Comment: 25 pages, 25 images, 86 references used, with authors biographie

SensorCloud: Towards the Interdisciplinary Development of a Trustworthy Platform for Globally Interconnected Sensors and Actuators

Although Cloud Computing promises to lower IT costs and increase users' productivity in everyday life, the unattractive aspect of this new technology is that the user no longer owns all the devices which process personal data. To lower scepticism, the project SensorCloud investigates techniques to understand and compensate these adoption barriers in a scenario consisting of cloud applications that utilize sensors and actuators placed in private places. This work provides an interdisciplinary overview of the social and technical core research challenges for the trustworthy integration of sensor and actuator devices with the Cloud Computing paradigm. Most importantly, these challenges include i) ease of development, ii) security and privacy, and iii) social dimensions of a cloud-based system which integrates into private life. When these challenges are tackled in the development of future cloud systems, the attractiveness of new use cases in a sensor-enabled world will considerably be increased for users who currently do not trust the Cloud.Comment: 14 pages, 3 figures, published as technical report of the Department of Computer Science of RWTH Aachen Universit

International conference on software engineering and knowledge engineering: Session chair

The Thirtieth International Conference on Software Engineering and Knowledge Engineering (SEKE 2018) will be held at the Hotel Pullman, San Francisco Bay, USA, from July 1 to July 3, 2018. SEKE2018 will also be dedicated in memory of Professor Lofti Zadeh, a great scholar, pioneer and leader in fuzzy sets theory and soft computing. The conference aims at bringing together experts in software engineering and knowledge engineering to discuss on relevant results in either software engineering or knowledge engineering or both. Special emphasis will be put on the transference of methods between both domains. The theme this year is soft computing in software engineering & knowledge engineering. Submission of papers and demos are both welcome

Customized agile development process for embedded software development

Agile software development has grown in popularity starting from the agile manifesto declared in 2001. However there is a strong belief that the agile methods are not suitable for embedded, critical or real-time software development, even though multiple studies and cases show differently. This thesis will present a custom agile process that can be used in embedded software development. The reasons for presumed unfitness of agile methods in embedded software development have mainly based on the feeling of these methods providing no real control, no strict discipline and less rigor engineering practices. One starting point is to provide a light process with disciplined approach to the embedded software development. Agile software development has gained popularity due to the fact that there are still big issues in software development as a whole. Projects fail due to schedule slips, budget surpassing or failing to meet the business needs. This does not change when talking about embedded software development. These issues are still valid, with multiple new ones rising from the quite complex and hard domain the embedded software developers work in. These issues are another starting point for this thesis. The thesis is based heavily on Feature Driven Development, a software development methodology that can be seen as a runner up to the most popular agile methodologies. The FDD as such is quite process oriented and is lacking few practices considered commonly as extremely important in agile development methodologies. In order for FDD to gain acceptance in the software development community it needs to be modified and enhanced. This thesis presents an improved custom agile process that can be used in embedded software development projects with size varying from 10 to 500 persons. This process is based on Feature Driven Development and by suitable parts to Extreme Programming, Scrum and Agile Modeling. Finally this thesis will present how the new process responds to the common issues in the embedded software development. The process of creating the new process is evaluated at the retrospective and guidelines for such process creation work are introduced. These emphasize the agility also in the process development through early and frequent deliveries and the team work needed to create suitable process.Siirretty Doriast
