27. Variability Management in Software Product Lines: An Investigation of Contemporary Industrial Challenges.

Author

Chen, Lianping and Babar, Muhammad Ali

Abstract

Variability management is critical for achieving the large scale reuse promised by the software product line paradigm. It has been studied for almost 20 years. We assert that it is important to explore how well the body of knowledge of variability management solves the challenges faced by industrial practitioners, and what are the remaining and (or) emerging challenges. To gain such understanding of the challenges of variability management faced by practitioners, we have conducted an empirical study using focus group as data collection method. The results of the study highlight several technical challenges that are often faced by practitioners in their daily practices. Different from previous studies, the results also reveal and shed light on several non-technical challenges that were almost neglected by existing research. [ABSTRACT FROM AUTHOR]

28. Middleware Architecture Evaluation for Dependable Self-managing Systems.

Author

Liu, Yan, Babar, Muhammad Ali, and Gorton, Ian

Abstract

Middleware provides infrastructure support for creating dependable software systems. A specific middleware implementation plays a critical role in determining the quality attributes that satisfy a system΄s dependability requirements. Evaluating a middleware architecture at an early development stage can help to pinpoint critical architectural challenges and optimize design decisions. In this paper, we present a method and its application to evaluate middleware architectures, driven by emerging architecture patterns for developing self-managing systems. Our approach focuses on two key attributes of dependability, reliability and maintainability by means of fault tolerance and fault prevention. We identify the architectural design patterns necessary to build an adaptive self-managing architecture that is capable of preventing or recovering from failures. These architectural patterns and their impacts on quality attributes create the context for middleware evaluation. Our approach is demonstrated by an example application – failover control of a financial application on an enterprise service bus. [ABSTRACT FROM AUTHOR]

29. Project Cost Overrun Simulation in Software Product Line Development.

Author

Hutchison, David, Kanade, Takeo, Kittler, Josef, Kleinberg, Jon M., Mattern, Friedemann, Mitchell, John C., Naor, Moni, Nierstrasz, Oscar, Pandu Rangan, C., Steffen, Bernhard, Sudan, Madhu, Terzopoulos, Demetri, Tygar, Doug, Vardi, Moshe Y., Weikum, Gerhard, Münch, Jürgen, Abrahamsson, Pekka, Nonaka, Makoto, Zhu, Liming, and Babar, Muhammad Ali

Abstract

The cost of a Software Product Line (SPL) development project sometimes exceeds the initially planned cost, because of requirements volatility and poor quality. In this paper, we propose a cost overrun simulation model for time-boxed SPL development. The model is an enhancement of a previous model, specifically now including: consideration of requirements volatility, consideration of unplanned work for defect correction during product projects, and nominal project cost overrun estimation. The model has been validated through stochastic simulations with fictional SPL project data, by comparing generated unplanned work effort to actual change effort, and by sensitivity analysis. The result shows that the proposed model has reasonable validity to estimate nominal project cost overruns and its variability. Analysis indicates that poor management of requirements and quality will almost double estimation error, for the studied simulation settings. [ABSTRACT FROM AUTHOR]

30. De-motivators of Software Process Improvement: An Analysis of Vietnamese Practitioners' Views.

Author

Hutchison, David, Kanade, Takeo, Kittler, Josef, Kleinberg, Jon M., Mattern, Friedemann, Mitchell, John C., Naor, Moni, Nierstrasz, Oscar, Pandu Rangan, C., Steffen, Bernhard, Sudan, Madhu, Terzopoulos, Demetri, Tygar, Doug, Vardi, Moshe Y., Weikum, Gerhard, Münch, Jürgen, Abrahamsson, Pekka, Niazi, Mahmood, and Babar, Muhammad Ali

Abstract

We have conducted face-to-face questionnaire based survey sessions with twenty-three Vietnamese software practitioners in order to determine software process improvement (SPI) de-motivators. The main objective of this study is to provide SPI practitioners with some insight into designing appropriate SPI implementation strategies and to maximize practitioners support for SPI. We asked practitioners to choose and rank various SPI de-motivator against the five types of assessments (high, medium, low, zero or do not know). From this, we propose the notion of 'perceived value' associated with each SPI de-motivator. We have identified 'high' and 'medium' perceived values demotivators that can undermine SPI initiatives. We have identified what demotivates developers and managers to be actively involved in SPI initiatives. We have also identified SPI de-motivators of small-medium and large sized organisations.
