Software Process Lines: A Systematic Literature Review

Software Process Line (SPrL) has been claimed as a suitable paradigm for tailoring and reuse of software processes. However, despite its increasing importance, there is still a lack of research that systematically characterizes and analyzes the state of the art of SPrL approaches, in particular focusing on how such a paradigm has been used to improve software processes. This paper presents the method followed to perform a systematic literature review on SPrL in order to investigate the state of the art of this area, as well as the results of this review focusing especially on how variability is represented. We found 40 primary studies about this topic published from 1996 to 2013. Our results indicate that the software engineering community has increasingly invested effort in this area. However, it is still considered an immature area with many open issues such as the lack of the modeling of well-known process standards and models using SPrL concepts and the lack of empirical evaluations.

Systematic Literature Review on the Characteristics of Agile Project Management in the Context of Maturity Models

Popularity of Agile Methods is growing up and along with this popularity is also growing the interest in adopting these methods in conjunction with maturity models, like CMMI. Dozens of reports about this topic can be found with different results. Therefore, a Systematic Literature Review was conducted with the goal of identifying characteristics of agile project management in organizations using agile methods and maturity models. We accepted 34 primary studies published from 2001 to 2013. The results show that the area still lacks details on how to perform the software development activities, what techniques can be used to meet issues not directly addressed by agile methods without losing the desired agility and what tools can be used to facilitate the combination of approaches.

Automated support for human resource allocation in software process by cluster analysis

It is widely recognized the potential of using organizational data analysis to enable automated tools supporting process management task. The organizational repositories should be used in an active way to accordingly support dynamic decision-making process in software project management. In this paper, we briefly describe a research aiming to support the human resource allocation process in the software process context based on the analysis of organizational repositories. It intends to provide an organizational data analysis as a mean to take empirical evidence to perform fact-based decisions upon historical and ongoing organizational experiences. As the work is in its beginning, we also present some differences from other already existing approaches and the main challenges to be overcome through completion of this work.

Risk assessment on distributed software projects

Risk Assessment is a growing discipline on the context of distributed software projects. The complexity to develop software and the related knowledge require automated support for project managers in order to analyze actions to reduce the projects risks and measure the impact of such actions. My thesis aims to investigate an approach for the assessment of risks in globally distributed software projects. This research proposes to apply stochastic simulation technique to analyze project data and identify factors that are likely to impact team productivity and that could affect the teams ability to meet its schedule objective. We aim this thesis to be applied by project management groups to perform risk assessment early in the software development process and to help decision-making process.

Recursive ARMA modeling for thermoelectric modules

A thermoelectric module or Peltier module is a non-linear device that operates as a heat pump and can be controlled by electric current. A linear dynamic model that varies with operating condition is employed to describe the characteristic of the Peltier module. The procedure for estimating the model parameters is outlined. The effectiveness of the model is verified experimentally in the laboratory using a specially mounted characterization platform.

Assessing the Value Blueprint to Support the Design of a Business Ecosystem

Ecosystems are an important aspect of today’s software business, and can be beneficial to companies that can create and organize such ecosystems around their products. Unfortunately, creating such ecosystems is not an easy task. The value blueprint is a tool created by Adner, that allows a company to identify the different types of risks to be faced during the establishment of an ecosystem. In this paper we describe a case study conducted to assess the value blueprint as an effective tool to help in the design of new ecosystems. This case study is based on data about the Apple Watch. We report our evaluation of the value blueprint tool and provide recommendations for practitioners interested in establishing their own ecosystems and researchers interested in the design of ecosystems.

Empirical evidence of factors influencing project context in distributed software projects

This study was carried out to find the context and factors that can affect the productivity of a team of developers and testers in a distributed software project. We interviewed project members in order to understand the relationships between those project context factors and their impact on scheduling risk. Our results suggest that, from a testers site point of view, knowledge expertise and communication overhead are important factors influencing the allocation strategy and the team productivity. Also there is still a lack of empirical evidences to define which factors managers, developers and testers should be aware when setting up and executing a distributed software development project.

A hysteresis model for a VO/sub 2/ variable optical attenuator

Variable optical attenuators are largely employed in high capacity optical network systems. The material used in these devices should permit control of its reflectance or transmittance. Thin film of vanadium dioxide VO/sub 2/ seems to be an attractive material to build active optical components. The optical transmittance and reflectance of a VO/sub 2/ thin film is known to depend on the film temperature. Besides, the transmittance versus film temperature characteristic exhibits a hysteresis nonlinearity. The limiting loop proximity (L/sup 2/P) model, developed for magnetic hysteresis, is adapted for this hysteresis characteristics. The model parameters are estimated and the calculated optical transmittance is validated against experimental data.
