This paper presents a behavioral approach to specifying interactive multimedia applications. This requirements specification approach allows one to model sequence, parallelism, branching and iteration. Transitions due to events are subdivided into automatic, user and clock The transitions due to tasks to be done are subdivided into animate, image, sound, text and video, which are the elements of a multimedia application. The approach is relatively simple and easy to understand. A toolkit to support specification of requirements has also been developed. Future work includes the possibility of code generation translated from the text file containing information on graphical representation.

Understanding software requirements and customer needs is vital for all SW companies around the world. Lately clearly more attention has been focused also on the costs, cost-effectiveness, productivity and value of software development and products. This study outlines concepts, principles and process of implementing a value assessment for SW requirements. The main purpose of this study is to collect experiences whether the value assessment for product requirements is useful for companies, works in practice, and what are the strengths and weaknesses of using it. This is done by implementing value assessment in a case company step by step to see which phases possibly work and which phases possibly do not work. The practical industrial case shows that proposed value assessment for product requirements is useful and supports companies trying to find value in their products.

The research presented in the literature thus far on process deviations, inconsistencies and general nonconformance have all been very generic, process wide methodologies. Their application has also been limited to one domain, such as the software, business or manufacturing process. In this paper we differentiate between activity/general process nonconformance and resource based nonconformance which we treat as different and the mechanism for testing is treated in a different way. This research is aimed at identifying instances of nonconformance between an instantiation of a generic process and its associated process model by examining only the resources specified and observed. We propose a conceptual design model illustrated with a simple case study on this topic which although is not based on a software engineering process, illustrate simply how our model can benefit a real world situation across many domains alongside software engineering.

Security is an integral part of most software systems but it is not considered as an explicit part in the development process yet. Input validation is the most critical part of software security that is not covered in the design phase of software development life-cycle resulting in many security vulnerabilities. Our objective is to extend UML to new integrated framework for model driven security engineering leading to ideal way to design more secure software. Input validation in UML has not been addressed previously, hence we incorporate input validation into UML diagrams such as use case, class, sequence and activity. This approach has some advantages such as preventing from common input tampering attacks, having both security and convenience in software at high level of abstraction and ability of solving the problem of weak security background for developers.

The purpose of this work is to define a strategy for the generation of platform independent model (PIM) for the Brazilian satellite launcher (BSL) software, based on the model driven architecture (MDA) approach. To accomplish that, a generic software model is created, using design patterns, to represent a family of satellite launcher vehicles whose characteristics are similar. From this generic model, PIMs are generated for variations of launcher vehicles, based on MDA approach. This strategy can contribute to the development of the software for same-family satellite launcher vehicles, as it defines a systematic for activities related to software modeling, and also allows the increase of BSL software models reuse.

A range of technologies and teaching strategies may be used to improve the quality of teaching object- oriented (OO) concepts where there is a close relationship between OO analysis and design (OOAD) combined with OO programming (OOP). This study investigates the application of a number of these technologies and teaching strategies across university courses in OOAD and OOP, using an empirical approach based upon attitudinal and student performance data. The systems used include: development environments that provide two-way linkage between UML diagrams and OO program code; interactive whiteboards to allow educational demonstrations that more closely represent actual practice; and an online delivery tool for course content, messages and discussions. Close integration between the processes of OOAD and OOP courses is also investigated. The approaches significantly improved student grades, perceived levels of understanding and productivity. The integration of course concepts and assignments, and the electronic discussion boards, are key benefit drivers.

There are many methods available for prioritising software requirements. Choosing the most suitable one can often be quite difficult. A number of factors need to be considered such as the project development methodology being used, the amount of time available, the amount of information known about requirements, the stage of the project and the degree of information about priority required. This paper examines the type of information available at different stages in a project and matches it to the properties of prioritisation methods. It then recommends the usage of specific prioritisation methods at certain stages of a project.

Knowledge representation for specific dominions through ontologies has received great interest, although it is no yet evident an appropriate integration of sub-dominions that contemplate complementary spaces of interpretation. From ontology of dominion of university institutions developed by the authors, it is tried to improve that supported on integration strategic tools. A methodological variant suggested by APFEL is tested, under the context of FOAM incorporated in protege-PROMPT. This proposal considers the systemic quality cube as a reference framework to determine the proportions to the quality of the process and product of incremental integration when "adding and/or adapting" significant semantic and logics, "from the excellent knowledge" from the experts. They were taken from other two public ontologies about the similar domains developed by other ones. A partial evaluation of the resulting ontology was made combining technical of validation complemented with the visual interaction experts through a process based on the support-cognitive paradigm.

Previous studies of Object-Oriented (OO) software have reported avoidance of the inheritance mechanism and cast doubt on the wisdom of 'deep' inheritance levels. From an evolutionary perspective, the picture is unclear - we still know relatively little about how, over time, changes tend to be applied by developers. Our conjecture is that an inheritance hierarchy will tend to grow 'breadth-wise' rather than 'depth-wise'. This claim is made on the basis that developers will avoid extending depth in favour of breadth because of the inherent complexity of having to understand the functionality of superclasses. Thus the goal of our study is to investigate this empirically. We conduct an empirical study of seven Java Open-Source Systems (OSSs) over a series of releases to observe the nature and location of changes within the inheritance hierarchies. Results showed a strong tendency for classes to be added at levels one and two of the hierarchy (rather than anywhere else). Over 96% of classes added over the course of the versions of all systems were at level 1 or level 2. The results suggest that changes cluster in the shallow levels of a hierarchy; this is relevant for developers since it indicates where remedial activities such as refactoring should be focused.

Handling problems and defects in software development projects is still a difficult matter in many organizations. The problems' analyses, when performed, usually do not focus on the problems sources and root causes. As a result, bad decisions are taken and the problem is not solved or can even be aggravated by rework, dissatisfaction and increases cost due to lack of quality. These difficulties make it hard for organizations that adopt the CMMI model to implement the Causal Analysis and Resolution (CAR) process area in software projects, as projects usually have to deal with very limited resources. In this context, this work proposes an approach, called MiniDMAIC, for analyzing and resolving defect and problem causes in software development projects. The MiniDMAIC approach is based on Six Sigma's DMAIC methodology and the Causal Analysis and Resolution process area from CMMI Level 5.
