Decisions in software development proyects management: an exploratory study.

Given the importance of software in today's world, the development of software systems is a key activity that requires complex management scenarios. This article explores the implications of hard decisions in the context of software development projects (SDPs). More in deep, it focuses on the emotional consequences of making hard decisions in IT organisations. Complex SDPs involve a great variety of actors. This fact entails morale, feelings and emotions, which play an important role for communication, interaction and, ultimately, decision making. The aim of the article is twofold. First (Study 1), to identify which are the most important hard decisions in SDPS. Second (Study 2), to study the influence of emotions on decision-making processes (Study 2). Findings show the complex emotional consequences and difficulties that managers must face in hard decision-making processes.Publicad

Gottfried Konecny: The photogrammetric and remote sensing trend setter

PREFACE: There are various publications on the 90th birthday of Gottfried Konecny. His involvement in the International Society for Photogrammetry and Remote Sensing (ISPRS) is particularly described by others. Here, his forward-oriented impulses in research and development at the former Institute for Photogrammetry and Engineering Survey of the (Technical) University of Hannover, today Institute for Photogrammetry and Geoinformation, Leibniz University Hannover, and some of his activities supporting developing and other countries by given short-term courses are highlighted. Gottfried Konecny was always one of the first in pushing new technologies. With the analytical plotter AP/C-3, he introduced analytical photogrammetry in Germany. Based on his experience with this not really operational version, he induced the company Zeiss to develop the first really operational analytical plotter Planicomp, which resulted in the end of analog photogrammetric devices and their limitations. At the invitation of Gilbert Hobrough, a mainly hardware-based image correlator was developed for the AP/C-3 in Hannover which anticipated many of today’s applications. Gottfried Konecny initiated remote sensing in Germany. Based on his proposal with the Metric Camera Flight on Spacelab, the then highest resolution civil stereoscopic space images available were generated. Despite limited computer performance at his institute, a digital stereo plotter was developed, using hardware components from the cooperating Swedish company Context Vision, long before digital stereo workstations with increased and affordable computer capacity were possible. Also, in the area of GIS, he too, pushed development in collaboration with companies and administrations. Shortly before the end of his time as head of the institute, and more so after he became emeritus professor, he started a series of educational workshops, particularly in developing countries, but also other countries, to support the development of photogrammetry, remote sensing and GIS. He promoted the use of space imagery for mapping to improve the situation of poorly updated topographic maps. © 2020 Wuhan University.

Human machine interface performance and instrumentation for high availability systems

Trabalho de projecto de mestrado, Engenharia Informática (Sistemas de Informação), Universidade de Lisboa, Faculdade de Ciências, 2010Air Traffic Control (ATC) provides services whose objective is to manage aircrafts to ensure safely orderly and expeditious flows of traffic. The LISATM system has a number of Controller Working Positions equipped with surveillance display applications, the Operator Display System (ODS). Due to redundancy requirements, there are two equivalent applications developed with different technologies. This project focused on the Air Situation Display System (ASD), na application which provides a surveillance display with user-interaction capability and is developed in Java technology. The application integrates the Radar Fallback keeping the looks and feels from the ODS System, only being developed in a different programming language. Thus the present work focused on monitoring the performance of high availability Real-Time Human-Machine Interface applications. Recommendations were endorsed for quantifiable performance, being these activities accompanied by a corresponding demonstration of results suitability for the intended context. Modules were defined in order to instrument applications Human-Machine Interface High Performance and High Availability (HMI-HPHA) with features necessary and sufficient for the pursuit of Real- Time performance analysis. These modules were developed using JAVA technology using the Java Management eXtensions (JMX), to manage the created agents. All the monitoring services run in real-time so it can inform the managers of changes of the application state as soon as it happens. This implies that the information provided needs to be not only concise but also adequate to the context.O Controle de Tráfego Aéreo (ATC) presta serviços, cujo objectivo é direccionar o fluxo de aeronaves para garantir a ordem, rapidez e segurança do tráfego, bem como para dar informações aos pilotos. O sistema LISATM tem um número de postos de trabalho, para os controladores, equipado com aplicações de vigilância radar (Display System Operator - ODS). Devido a requisitos de redundância, existem duas aplicações equivalentes desenvolvidas com diferentes tecnologias. Este projecto focou-se no Air Display System (ASD). Aplicação que fornece vigilância radar com capacidade de interacção com o utilizador, sendo desenvolvido com tecnologia Java. A aplicação integra o Radar Fallback, mantendo o aspecto e mecânica de utilização igual ao Sistema ODS, com a diferença a residir na linguagem de programação. O foco do presente projecto incidiu sobre o desempenho de aplicações de Interface Homem-Máquina em Tempo-Real de elevada disponibilidade. Desta forma foram elaboradas propostas de recomendações de desempenho quantificáveis a serem incorporadas no ciclo de desenvolvimento de aplicações HMI-HPHA (Human-Machine Interface High Performance and High Availability). Estas foram acompanhadas da correspondente demonstração da adequabilidade ao contexto pretendido. Para isso foram definidos e desenvolvidos módulos de forma a instrumentar a aplicação HMIHPHA com as funcionalidades necessárias e suficientes para a persecução da análise de desempenho. Estes módulos foram desenvolvidos com recurso à tecnologia JAVA e às ferramentas de automatização dos mesmos, usando Java Management eXtensions (JMX) para gerir os agentes desenvolvidos. Todos os serviços de monitoria foram executados em Tempo-Real de modo a informar os gestores aquando de alguma mudança de estado da aplicação. Estas informações necessitam não só de ser concisas, mas também adequadas ao contexto
