A new model for the development of information systems

The most commonly used systems specification and design techniques in commercial computing are described and compared; Information Engineering as proposed by James Martin, A Framework for Information Definition-Muitiview proposed by Wood-Harper et al, Real-world Modeling as described by Jackson, Structured Analysis and Design as In Demarco, Yourdon and Constantine and Output-Oriented Structured Requirement Definition proposed by Orr. In addition, system prototyping is discussed, including the role of prototyping in large software development projects and as a tool for the design of human-computer interfaces. Other areas described and discussed include decision support systems (DSS) and knowledge based management support systems. The context is in the design and development approaches for DSS, prototyping for DSS, expert system for DSS and the integration of DSS and information system. The design and development of human-computer interface is also discussed in relation to user Interface complexity and adaptive interfaces. Further, the important issue of user involvement and support within the development process Is discussed. Thus, weaknesses of current approaches to the system development process are identified and a new model for the development of information system is proposed. In proposing the model, data and functional analysis structured method and methodology for decision support systems (DSS) development is presented including guidelines for the development of knowledge based DSS. The new proposed model is put to test in the design, development and implementation of large integrated commercial systems including DSS. Results and discussion on the use of the model is reported with special consideration to the users' and developers' view of the model. Finally the objectives of this research program are examined in relation to what has been achieved during this program of research. The prospect of using the model for the development of information systems are concluded with references to current and future goals

State diagram design application for EDAG Production Solutions

En este trabajo de fin de grado se presenta el desarrollo realizado de una aplicación de escritorio para la empresa EDAG Production Solutions GmbH & Co. KG, dedicada a implementar soluciones de producción para sus clientes. Dentro de la empresa, los desarrolladores de software del departamento de producción IT emplean distintas herramientas software al trabajar en las diferentes fases que un proyecto requiere, y, como le ocurre a otras empresas, para ciertos casos el mercado no ofrece soluciones accesibles cuando se trata de resolver problemas concretos. En concreto, EDAG Production Solutions GmbH & Co. KG necesita para el departamento de producción IT una aplicación de escritorio para diseñar diagramas que representan el comportamiento de un sistema y que, a partir de este diseño, genere automáticamente una plantilla del diagrama escrito en Java, ya que esta tarea se realiza manualmente y el tiempo de desarrollo de un proyecto se reducirá notablemente con esta herramienta. Actualmente, la empresa no ve adecuadas las soluciones existentes ya que o no son software libre o no permiten generar código a partir de un diagrama de la forma que necesitan. Además, estas herramientas no son intuitivas y demasiado complejas para lo que realmente necesita la empresa, por ello buscan una solución más adecuada a sus necesidades. La aplicación desarrollada como trabajo final de grado permite esta funcionalidad que EDAG Production Solutions GmbH & Co. KG necesita. Además de la importación y exportación de diagramas en formato GraphML. Esta aplicación se ha desarrollado utilizando Angular, un framework para desarrollar aplicaciones web, sobre Electron, un framework de código abierto que permite ejecutar componentes para aplicaciones web en una aplicación de escritorio compatible con los sistemas operativos para ordenador más utilizados

Human Factors in Agile Software Development

Through our four years experiments on students' Scrum based agile software development (ASD) process, we have gained deep understanding into the human factors of agile methodology. We designed an agile project management tool - the HASE collaboration development platform to support more than 400 students self-organized into 80 teams to practice ASD. In this thesis, Based on our experiments, simulations and analysis, we contributed a series of solutions and insights in this researches, including 1) a Goal Net based method to enhance goal and requirement management for ASD process, 2) a novel Simple Multi-Agent Real-Time (SMART) approach to enhance intelligent task allocation for ASD process, 3) a Fuzzy Cognitive Maps (FCMs) based method to enhance emotion and morale management for ASD process, 4) the first large scale in-depth empirical insights on human factors in ASD process which have not yet been well studied by existing research, and 5) the first to identify ASD process as a human-computation system that exploit human efforts to perform tasks that computers are not good at solving. On the other hand, computers can assist human decision making in the ASD process.Comment: Book Draf

Sales Management Portal

In any business organization, sales is the department that generates revenue. No matter how good your manufacturing operation is, how cutting-edge your technology is, how tight your financial goals are or how progressive and forward-thinking your management techniques are, you must still have a sales mechanism in place, or everything else is useless. Why is this project important? A sales management portal is a phenomenal way to explain the importance of marketing or sales within the organization. it involves the possible way for all the people to get connected and get the information they may need for potential sales. Indeed, portal is a doorway for the process of marketing and get to the next step of any business. What problem does it solves? This project will cover all the options about the selling activities, where management can easily access the detailed report about the sales team and managing their performance. Therefore, the management will have the option of accessing updated information through their DASHBOARD and can leave important notes to the employee. The other important benefit includes, all the information about the clients and the communication between the sales team and the managers will be easily accessible for future purposes. Does it provide a new application/service, replace an existing application/service, or enhance an existing application/service? This project will cover more focused functionalities, such as: USER FRIENDLY OPTIONS: the designed features used in this project is easily understandable to anyone. NOTES: this is an additional feature, where the sales team can leave their opinion or comments in order to know the management about the ongoing work, which in turn the management can give their feedbacks. OPPORTUNITY: in addition to above, there is another feature included in this project where the sales person can easily evaluate the possibility of having opportunities to finalize the initiation of project. The Sales Management Portal will be available for its final presentation and release before 5th December 2016
