Estimating, planning and managing Agile Web development projects under a value-based perspective
Context: The processes of estimating, planning and managing are crucial for software development projects,
since the results must be related to several business strategies. The broad expansion of the Internet
and the global and interconnected economy make Web development projects be often characterized by
expressions like delivering as soon as possible, reducing time to market and adapting to undefined
requirements. In this kind of environment, traditional methodologies based on predictive techniques
sometimes do not offer very satisfactory results. The rise of Agile methodologies and practices has
provided some useful tools that, combined with Web Engineering techniques, can help to establish a
framework to estimate, manage and plan Web development projects.
Objective: This paper presents a proposal for estimating, planning and managing Web projects, by
combining some existing Agile techniques with Web Engineering principles, presenting them as an
unified framework which uses the business value to guide the delivery of features.
Method: The proposal is analyzed by means of a case study, including a real-life project, in order to obtain
relevant conclusions.
Results: The results achieved after using the framework in a development project are presented, including
interesting results on project planning and estimation, as well as on team productivity throughout the
project.
Conclusion: It is concluded that the framework can be useful in order to better manage Web-based
projects, through a continuous value-based estimation and management process.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-
Small business innovation research. Abstracts of completed 1987 phase 1 projects
Non-proprietary summaries of Phase 1 Small Business Innovation Research (SBIR) projects supported by NASA in the 1987 program year are given. Work in the areas of aeronautical propulsion, aerodynamics, acoustics, aircraft systems, materials and structures, teleoperators and robotics, computer sciences, information systems, spacecraft systems, spacecraft power supplies, spacecraft propulsion, bioastronautics, satellite communication, and space processing are covered
The NASA SBIR product catalog
The purpose of this catalog is to assist small business firms in making the community aware of products emerging from their efforts in the Small Business Innovation Research (SBIR) program. It contains descriptions of some products that have advanced into Phase 3 and others that are identified as prospective products. Both lists of products in this catalog are based on information supplied by NASA SBIR contractors in responding to an invitation to be represented in this document. Generally, all products suggested by the small firms were included in order to meet the goals of information exchange for SBIR results. Of the 444 SBIR contractors NASA queried, 137 provided information on 219 products. The catalog presents the product information in the technology areas listed in the table of contents. Within each area, the products are listed in alphabetical order by product name and are given identifying numbers. Also included is an alphabetical listing of the companies that have products described. This listing cross-references the product list and provides information on the business activity of each firm. In addition, there are three indexes: one a list of firms by states, one that lists the products according to NASA Centers that managed the SBIR projects, and one that lists the products by the relevant Technical Topics utilized in NASA's annual program solicitation under which each SBIR project was selected
Seafloor characterization using airborne hyperspectral co-registration procedures independent from attitude and positioning sensors
The advance of remote-sensing technology and data-storage capabilities has progressed in the last decade to commercial multi-sensor data collection. There is a constant need to characterize, quantify and monitor the coastal areas for habitat research and coastal management. In this paper, we present work on seafloor characterization that uses hyperspectral imagery (HSI). The HSI data allows the operator to extend seafloor characterization from multibeam backscatter towards land and thus creates a seamless ocean-to-land characterization of the littoral zone
Modelling the Requirements of Rich Internet Applications in WebRe
In the last years, several Web methodological approaches were
defined in order to support the systematic building of Web software. Together
with the constant technological advances, these methods must be constantly
improved to deal with a myriad of new feasible application features, such as
those involving rich interaction features. Rich Internet Applications (RIA) are
Web applications exhibiting interaction and interface features that are typical in
desktop software. Some specific methodological resources are required to deal
with these characteristics. This paper presents a solution for the treatment of
Web Requirements in RIA development. For this aim we present WebRE+, a
requirement metamodel that incorporates RIA features into the modelling
repertoire. We illustrate our ideas with a meaningful example of a business
intelligence application.Ministerio de Educación y Ciencia TIN2007-67843-C06-03Ministerio de Educación y Ciencia TIN2010-20057-C03-0

Decision support for build-to-order supply chain management through multiobjective optimization
This paper aims to identify the gaps in decision-making support based on
multiobjective optimization for build-to-order supply chain management (BTOSCM).
To this end, it reviews the literature available on modelling build-to-order
supply chains (BTO-SC) with the focus on adopting multiobjective optimization
(MOO) techniques as a decision support tool. The literature has been classified based
on the nature of the decisions in different part of the supply chain, and the key
decision areas across a typical BTO-SC are discussed in detail. Available software
packages suitable for supporting decision making in BTO supply chains are also
identified and their related solutions are outlined. The gap between the modelling and
optimization techniques developed in the literature and the decision support needed in
practice are highlighted and future research directions to better exploit the decision
support capabilities of MOO are proposed
