In this paper we present a 3D collaborative educational virtual environment, which was development by utilizing an iterative applied throughout development cycle. The main propose was demonstrating applicability of an evaluation framework idealized by the authors. Our evaluation framework is supported by the Quantitative Evaluation Framework (QEF) proposed by Escudeiro [3]. This framework uses ...

Pan Gas Gombong Store is a distributor of industrial gas and medical that sells cylinders. does not yet have system to process computerized data, therefore sales data recording still manual so lot lost, which causes long time for making transaction reports. With the existing problems, an oxygen cylinder information was built at Gombong. System development carried out using prototype method, PHP...

This paper elaborates on how to use clustering for the evaluation of a software system’s maintainability according to the ISO/IEC-9126 quality standard. More specifically it proposes a methodology that combines clustering and multicriteria decision aid techniques for knowledge acquisition by integrating groups of data from source code with the expertise of a software system’s evaluators. A proc...

In order to develop a software product for a critical system, specifying quality requirements is vitally important. Quality requirements should be defined based on various stakeholders’ needs. Software quality impacts the information system’s behavior, and the behavior impacts the behavior of the External-System that contains the information system. Safety is an issue of the External-System. A ...

The embedded system development methodology has not been as well established as the development methodology in software engineering. Involving inter-disciplinary activities in the development of hardware and software need to be further considered when developing an embedded system. This paper presents a new development model for an embedded system by the hybridization of selected development me...

In this article it is developed and it analyze a computational model based on the concepts of the Fuzzy Logic that it will allow the calculate the value of Usability to final user’s of software developments based on the Norma ISO/IECE 9126-1:2.001, and based on the Fuzzy Model of Takagi Sugeno Kang. For this model’s development it becomes necessary to keep in mind a series of attributes that th...

Usability has become a critical quality factor of software systems in general, and especially important regarding Web-based applications. Measuring quality is the key to developing high-quality software, and it is widely recognised that quality assurance of software products must be assessed focusing on the early stages of the development process. This paper describes a controlled experiment ca...

Making major changes in enterprise information systems, such as large IT-investments, often have a significant impact on business operations. Moreover, when deliberating which IT-changes to make, the consequences of choosing a certain scenario may be difficult to grasp. One way to ascertain the quality of IT-investment decisions is through the use of methods from decision theory. This paper pro...
