  • jopera an Agile Environment for web service composition with visual unit testing and refactoring
    Symposium on Visual Languages and Human-Centric Computing, 2005
    Co-Authors: Cesare Pautasso
    Abstract:

    Agile methodologies employ light-weight development practices emphasizing a test-driven approach to the development of software systems. Modern Agile development Environments support this approach by providing tools that automate most of the work required to effectively deal with change, including unit testing and different forms of refactoring. In this paper we discuss how to apply such techniques within the JOpera Visual Composition Language. More precisely, we show how we used the visual language to implement a regression testing framework for compositions written in the language itself and how we introduced support in the visual Environment for refactorings such as renaming, synchronization of service interface changes, and extraction/inlining across different levels of nesting. This is done in the context of the Web service composition tools provided with the JOpera for Eclipse research platform.

  • A Sprint Point Based Tool for Agile Estimation
    Software Engineering, 2019
    Co-Authors: Rashmi Popli, Naresh Chauhan
    Abstract:

    In Agile Environment, the software is developed by self-organizing and cross-functional teams. Agile promotes ad hoc programming, iterative, and incremental development and a time-boxed delivery approach. Agile is always flexible to changes. Estimation approaches of Agile are very different from traditional ones. However, research involving estimation in Agile methodologies is considerably less advanced. This paper focuses on the estimation phase of Agile software development which probably ranks as the crucial first step. Poor decisions related to estimation activity can cause software failures. In Agile Environment in order to support estimation, some delay-related factors are proposed that can delay the release date of the project and also a new Sprint-point based estimation tool (SPBE) is designed and developed in excel. The proposed tool is based on the Sprint-point based Estimation Framework and place major emphasis on accurate estimates of effort, cost, and release date by constructing detailed requirements as accurately as possible.

  • MANAGING UNCERTAINTY OF TIME IN Agile Environment
    Computer Science & Information Technology ( CS & IT ), 2014
    Co-Authors: Rashmi Popli, Priyanka Malhotra, Naresh Chauhan
    Abstract:

    Agile software development represents a major departure from traditional methods of software engineering. It had huge impact on how software is developed worldwide. Agile software development solutions are targeted at enhancing work at project level. But it may encounter some uncertainties in its working. One of the key measures of the resilience of a project is its ability to reach completion, on time and on budget, regardless of the turbulent and uncertain Environment it may operate within. Uncertainty of time is the problem which can lead to other uncertainties too. In uncertainty of time the main issue is that the how much delay will be caused by the uncertain Environment and if the project manager comes to know about this delay before, then he can ask for that extra time from customer. So this paper tries to know about that extra time and calculate it.

  • prioritising user stories in Agile Environment
    International Conference on Issues and Challenges in Intelligent Computing Techniques, 2014
    Co-Authors: Rashmi Popli, Naresh Chauhan, Hemant Sharma
    Abstract:

    In the last few years Agile methodologies appeared as a reaction to traditional software development methodologies. In Agile Environment the requirements from the client are always taken in the form of user-stories and prioritization of requirements is done by Moscow method, validate learning and walking skeleton methods. By literature survey it has been observed that these methods are not efficient because they do not consider importance of user-stories by client. In this research work some importance related and effort related factors are considered on the basis of which the prioritization of user-stories is done. Further the feasibility of work has been validated by a case study of Enable Quiz which is a lightweight technical quizzing solution; for companies that hire engineers. The research work will allows the companies to better screen job candidates and assess their internal talent for skills development.

  • Application of fuzzy VIKOR for concept selection in an Agile Environment
    The International Journal of Advanced Manufacturing Technology, 2013
    Co-Authors: S. Vinodh, Ashwin R. Varadharajan, Abhishek Subramanian
    Abstract:

    Due to the increasing competition, modern manufacturing organisations are adopting Agile manufacturing (AM) paradigm. AM enables the speedy production of customised, high-quality products in varying lot sizes. Concept selection in the context of AM is a typical multi-criterion decision making problem as it involves several agility criteria. The case organisation needs to select the best concept among five alternative designs. VIKOR (VlseKriterijumskaOptimizacija I KompromisnoResenje in Serbian, meaning multi-criteria optimization and compromise solution) has been used to select the best concept design. Based on the inputs gathered from decision makers, concept design (A3) has been found the best concept design from the perspective of agility. The result derived from Fuzzy VIKOR has been compared with fuzzy TOPSIS (technique for order preference by similarity to an ideal solution) methodology. The selected concept design has been subjected to implementation in the case organisation.
