One of the most essential problems during negotiations is to know what people aim to claim. Although it sounds strange, most professionals go into the negotiation table without enough preparation. Regarding preparation it is important to understand that this is the stage when professionals have to anticipate the counterpart's interests, alternatives, concessions and possible changes in strategy. Experienced negotiators usually keep in their mind the whole negotiation and, most of the time, they still have personal notes about the deal. Indeed, people have memory limits and this may disrupt even the cleverest ones. Therefore, Negotiation Support systems can help to store this information and also manipulate it in the future. In this direction, this work presents an environment focused on a negotiation preparation step, mainly considering knowledge management and mobile technologies. The article shows how these concepts may carry out the preparation stage, advantages to use it and available reports. Besides, some experiments and results will be also addressed in this work. © 2011 IEEE.

Software differs from most manufactured products because it is intangible. This characteristic makes it difficult to detect, control, and understand how it evolves. This paper presents an approach based on software visualization that can detect and externalize design evolution made in a software project during its initial development or at any further phase. By using this approach, a developer can be aware of the current state of the software as a whole and can additionally verify if the current design, also called emerging design, is evolving according to the team expectations and leader guidance, preventing problems caused by misunderstandings of the expected software solution. The approach was evaluated with free/open source software (FOSS) projects. The results indicate that the approach behaves as expected when applied to real software development projects, with minor performance bottlenecks. © 2010 The Brazilian computer Society.

Despite the fact that people frequently see software development as a commodity, decision-making processes in Information Technology (IT) projects usually require great effort in solving several types of conflicts. The main tool to solve such conflicts is negotiation, which requires strategies and personal skills. Preparation step is the cornerstone to lead successful deals, but one of the major issues faced by negotiators, especially beginners, is to find out when they are emotionally prepared. Regarding behavioral aspects, there are particularities in IT people's conduction, once they are more reasoning than other professionals. Thus, this work aims at presenting a research about how IT professionals face IT project's negotiations. The research was managed in Brazilian professionals and evaluated IT people's performance through psychological tests, behavioral simulations and negotiation games to set negotiator skills profile. In addition, some case studies and simulation results are presented. This exploration is important as a way to show possible characteristics of style and dominant skills used by IT people during software development deals. This study works as a fundamental starting point to realize the requirements to develop specific negotiation support systems to IT context.

The Metaverse is very challenging to implement solutions for eXtended Reality applications (XR apps), due to the combination of complex concerns that should be addressed: multiple users with non-traditional input and output devices, different hardware platforms that should be addressed, forceful interactive rates, and experimental interaction techniques, among other issues. Therefore, this work aims to present a Software Product Line (SPL)-based approach to support the development of Web XR apps. More specifically, we define a features model that represents similarities and variables (domain analysis);we defined a core composed of generic and reusable software artifacts (domain design);and we developed an interface to support the instantiation of a Web XR app family, named MetaSee Features Model Editor (domain implementation). This approach integrates with a component of the MetaSEE architecture (Metaverse for Software engineering Education). A preliminary assessment found that Features Model has conceptual consistency from the point of view of the complexity of Web XR Apps multimodal interaction. As future work, features model and artifacts will be increased with improvements and an evaluation with a significant number of participants will be performed. © 2022 IEEE.

Software inspections improve software quality by the analysis of software artifacts, detecting their defects for removal before these artifacts are delivered to the following software life cycle activities. Some knowledge regarding software inspections have been acquired by empirical studies. However, we found no indication that computational support for the whole software inspection process using appropriately such knowledge is available. This paper describes a computational framework whose requirements set was derived from knowledge acquired by empirical studies to support software inspections. To evaluate the feasibility of such framework, two studies have been accomplished: one case study, which has shown the feasibility of using the framework to support inspections, and an experimental study that evaluated the supported software inspection planning activity. Preliminary results of this experimental study suggested that unexperienced subjects are able to plan inspections with higher defect detection effectiveness, and in less time, when using this computational framework.

Decision-making processes in any context usually require great effort in solving regular conflicts. One approach to handle conflicts is through negotiation, which requires a wide range of strategies and personal skills. Moreover, during crisis periods, enterprises tend to downsize and the remaining professionals have to improve their negotiation aptitudes in order to maintain the organization alive. Experienced negotiators assert that the preparation stage is vital to achieve successful deals, but one of the major issues faced by negotiators, especially beginners, is to realize when they are technically and emotionally ready. Regarding the psychological side, sometimes it is difficult to measure how professionals behave when initiating negotiation modeling. Under this scenario, a Web Tool has been designed to support professionals to find out their levels of proficiency and behavior trends while negotiating. Therefore, this paper aims at presenting features of this environment, which combines psychological tests, behavioral simulations and negotiation games to set the negotiator skills profile. In addition, some studies and results are presented. © 2011 IEEE.

Software systems are growing quickly in needs of functionality, complexity, size and structure. Therefore, it becomes necessary to advance the ways where the software suffers changes, so it can be modified more easily to accommodate these needs. However, anticipating to the changes is not an easy task, once there are a lot of reasons why systems change. The Laws of Software Evolution describe how a system behaves throughout their successive versions regarding its decaying. Most of the experimental studies supporting these Laws are concerned with legacy systems' source code. However, we believe the Laws can also be observed and applied when dealing with other software development process phases, including evolutive maintenance. Therefore, we present a set of hypotheses to experimentally verify whether the Laws of Software Evolution can also be observed in the object-oriented software. A case study demonstrating the framework's use is also described.

Software development depends on diverse technologies and methods and as a result, software development teams often handle issues in which team members are not experts. In order to address this lack of expertise, developers typically search for information on web-based Q&A sites such as Stack Overflow, a well-known place to find solutions to specific technology-related problems. The access to these web-based Q&A locations is currently not integrated into the software development environment, and because the associations between software development processes and the supporting sources of known solutions, usually referred to as knowledge, is not explicitly modeled and recorded, software developers often need to search for solutions to similar recurring issues multiple times. Moreover, this lack of integration hampers the implementation of a proactive recommender system that can point developers to knowledge that is relevant to their development processes. This research aims at proposing a solution that explicitly associates process elements (such as project tasks) to Stack Overflow posts and presents a recommender system that proactively recommends Stack Overflow posts to developers based on the similarity of project tasks. A literature review was used to find the concepts to define a meta-model for project tasks. This research paper advances the area of software development knowledge reuse by reporting on both the model and the results of experiments performed with real project development data. © 2018 Conferencia Iberoamericana de Software engineering - CIbSE.

Software development comprises the execution of a variety of tasks, such as bug discovery, finding reusable assets, dependency analysis etc. A better understanding of the task at hand and its surroundings can improve the development performance in general. Software visualizations can support such understanding by addressing different issues according to the necessity of stakeholders. However, knowing which visualizations better fit a given task in progress is not a trivial skill. In this sense, a feature model, intended for organizing the knowledge of a given domain and allowing the reuse of components, can support the identification, categorization and selection of information visualization elements. This work presents an ongoing domain analysis performed for building an information visualization feature model, whose goal is to support the process of choosing and building proper, suitable software visualizations.

Collaboration monitoring in software process is important to check if the collaboration is indeed happening as planned, but there are few approaches that define how to measure and monitor collaboration. By assessing collaboration during an ongoing process execution, project managers can take corrective actions that might improve the process execution and, consequently, reflect on quality gains of the final product. This research work proposes to evaluate the level of coordination achieved by a running software process through social network analysis metrics. © 2014 Springer International Publishing.
