  • Evaluating and Comparing Perceptions Between Undergraduate Students and Practitioners in Controlled Experiments for Requirements Prioritization
    Advances in Intelligent Systems and Computing, 2015
    Co-Authors: José Antonio Pow-sang
    Abstract:

    The Use Case Precedence Diagram (UCPD) is a technique that addresses the problem of determining the construction sequence or prioritization of a software product from the developer’s perspective in software development projects. This paper presents a perceptions evaluation of the UCPD based on the Method Evaluation Model (MEM), where the intention to use a method is determined by the users’ perceptions. Perceptions were collected using a questionnaire which was applied immediately after the controlled experiments were carried out. Those controlled experiments were replicated twice with undergraduate students, and twice with practitioners. The results show that the intentions to use UCPD exist in undergraduate students and practitioners with at least 2 years of experience in the industry, but the relationships defined by the MEM are best confirmed with the results obtained with practitioners.

  • FGIT-ASEA/DRBC/EL - A Replicated Experiment with Undergraduate Students to Evaluate the Applicability of a Use Case Precedence Diagram Based Approach in Software Projects
    Communications in Computer and Information Science, 2011
    Co-Authors: José Antonio Pow-sang, Ricardo Imbert, Ana Moreno
    Abstract:

    The Use Case Precedence Diagram (UCPD) is a technique that addresses the problem of determining the construction sequence or prioritization of a software product from the developer’s perspective. This paper presents a replicated controlled experiment with undergraduate students. The results obtained from this experiment confirm the results obtained in previous studies with practitioners in which the proposed approach enables developers to define construction sequences more precisely than with other ad-hoc techniques. However, unlike previous studies with practitioners, qualitative evaluation of the UCPD based on the Method Adoption Model (MAM), where the intention to use a method is determined by the users’ perceptions, shows that the relationships defined by the MAM are not confirmed with the results obtained with undergraduate students.

  • FGIT - Evaluating the Intention to Use the Use Case Precedence Diagram in Software Development Projects
    Future Generation Information Technology, 2010
    Co-Authors: José Antonio Pow-sang
    Abstract:

    The Use Case Precedence Diagram (UCPD) is a technique that addresses the problem of determining a software’s scope and construction sequence from the developer’s perspective. This paper presents a qualitative evaluation of the UCPD based on the Method Adoption Model (MAM), where the intention to use a method is determined by the users’ perceptions. The results show that the intentions to use UCPD exist in undergraduate students and practitioners with at least 2 years of experience in the industry, but the relationships defined by the MAM are only confirmed with the results obtained with practitioners.

  • evaluating the applicability of a use case Precedence Diagram based approach in software development projects through a controlled experiment
    International Conference on Security Technology, 2008
    Co-Authors: Jose Antonio Powsang, Ana Moreno, Arturo Nakasone, Ricardo Imbert
    Abstract:

    Use Cases are the most utilized technique to specify software requirements. Currently, there are several proposals based on this technique to address the problem of determining the scope and construction sequence of a software, but most of them lack ease of use from the developer’s perspective. In this paper, we present an approach to determine software construction sequences which emphasizes easiness from the developers’ point of view and a controlled experiment based on this approach with professionals who have had at least two years of experience in software projects. The results obtained from this experiment show that our approach enables developers to define construction sequences more precisely than with other ad-hoc techniques.

  • optimasi dan penyusunan ulang schedule proyek pembangunan pipa gas grissik pusri dengan menggunakan metode Precedence Diagram method time cost trade off
    Proceedings Conference on Piping Engineering and its Application, 2018
    Co-Authors: Noer Pratomo Pudjo, Rizal Mochammad Choirul
    Abstract:

    On a project there is often a problem or constraint outside of the initial planning of the project, so that delays in a project will inevitably occur. The delay that occurs will cause the duration and cost of the planned project will not be equal to the duration and cost of project implementation. One way to anticipate it by doing optimization. The Grissik-Pusri Gas Pipeline Project was selected for the research study due to delays in its completion. Optimization is done by making the network using Precedence Diagram Method to get critical jaluk, then calculation of productivity and cost of work on critical path then using Time Cost Trade Off method to compare the addition of working hours and workers used to determine the duration and optimum cost in project work. From the analysis results obtained work with the addition of working hours cost Rp. 21.923.400.000,00 and duration of 5 months, while work with the addition of workers cost Rp. 17.544.000.000,00  and 3.5 months duration. Timing optimization using the addition of workers is selected because it can solve the problem of delay that occurred without adding the total duration of the project

  • When the project absolutely must get done: marrying the organization chart with the Precedence Diagram
    Proceedings of the 2000 International Conference on Software Engineering. ICSE 2000 the New Millennium, 2000
    Co-Authors: Stan Rifkin
    Abstract:

    Presents a new project planning technique to marry the organization chart with a project's task Precedence Diagram. This permits one to simulate the project at a micro-scale, project-specific level. One can perform "what-if" scenarios related to organizational structures, the deployment of specific individuals and skills, and the structure of information flow and exception handling in a project. The tool used, ViteProject, was developed in a Stanford University laboratory, where substantial results have been achieved when it was applied to design activities other than software. The author presents his real-world experience with several software projects, where ViteProject has improved project visibility and allowed projects to be rationally optimized in a way that has hitherto been impossible.

    Abstract:

    Very little is new in project planning, but this is! We present a technique to marry the organization chart with a project's task Precedence Diagram. This permits us to simulate the project at a micro, project-specific level never before achieved. We can perform “what-if” scenarios related to organization structures, the deployment of specific individuals and skills, and the structure of information flow and exception-handling in a project. The tool used, ViteProject, was developed over the last ten years in a Stanford University laboratory, where substantial results have been achieved when applied to design activities other than software. We present our real-world experience with several software projects, where it has improved project visibility and allowed us to rationally optimize projects in a way hitherto impossible.
