Software product lines (SPL) are used in industry to achieve more efficient software development. However, the testing side of SPL is underdeveloped.Objective
This study aims at surveying existing research on SPL testing in order to identify useful approaches and needs for future research.Method
A systematic mapping study is launched to find as much literature as possible, and the 64 papers found are classified with respect to focus, research type and contribution type.Results
A majority of the papers are of proposal research types (64%). System testing is the largest group with respect to research focus (40%), followed by management (23%). Method contributions are in majority.Conclusions
More validation and evaluation research is needed to provide a better foundation for SPL testing. 相似文献2.

Release scheduling deals with the selection and assignment of deliverable features to a sequence of consecutive product deliveries while several constraints are fulfilled. Although agile software development represents a major approach to software engineering, there is no well-established conceptual definition and sound methodological support of agile release scheduling.Objective
To propose a solution, we present, (1) a conceptual model for agile scheduling, and (2) a novel multiple knapsack-based optimization model with (3) a branch-and-bound optimization algorithm for agile release scheduling.Method
To evaluate our model simulations were carried out seven real life and several generated data sets.Results
The developed algorithm strives to prevent resource overload and resource underload, and mitigates risks of delivery slippage.Conclusion
The results of the experiment suggest that this approach can provide optimized semi-automatic release schedule generations and more informed and established decisions utilizing what-if-analysis on the fly to tailor the best schedule for the specific project context. 相似文献3.

During development managers, analysts and designers often need to know whether enough requirements analysis work has been done and whether or not it is safe to proceed to the design stage.Objective
This paper describes a new, simple and practical method for assessing our confidence in a set of requirements.Method
We identified four confidence factors and used a goal oriented framework with a simple ordinal scale to develop a method for assessing confidence. We illustrate the method and show how it has been applied to a real systems development project.Results
We show how assessing confidence in the requirements could have revealed problems in this project earlier and so saved both time and money.Conclusion
Our meta-level assessment of requirements provides a practical and pragmatic method that can prove useful to managers, analysts and designers who need to know when sufficient requirements analysis has been performed. 相似文献4.

Although agile software development methods such as SCRUM and DSDM are gaining popularity, the consequences of applying agile principles to software product management have received little attention until now.Objective
In this paper, this gap is filled by the introduction of a method for the application of SCRUM principles to software product management.Method
A case study research approach is employed to describe and evaluate this method.Results
This has resulted in the ‘agile requirements refinery’, an extension to the SCRUM process that enables product managers to cope with complex requirements in an agile development environment. A case study is presented to illustrate how agile methods can be applied to software product management.Conclusions
The experiences of the case study company are provided as a set of lessons learned that will help others to apply agile principles to their software product management process. 相似文献5.

In order to ensure high quality of a process model repository, refactoring operations can be applied to correct anti-patterns, such as overlap of process models, inconsistent labeling of activities and overly complex models. However, if a process model collection is created and maintained by different people over a longer period of time, manual detection of such refactoring opportunities becomes difficult, simply due to the number of processes in the repository. Consequently, there is a need for techniques to detect refactoring opportunities automatically.Objective
This paper proposes a technique for automatically detecting refactoring opportunities.Method
We developed the technique based on metrics that can be used to measure the consistency of activity labels as well as the extent to which processes overlap and the type of overlap that they have. We evaluated it, by applying it to two large process model repositories.Results
The evaluation shows that the technique can be used to pinpoint the approximate location of three types of refactoring opportunities with high precision and recall and of one type of refactoring opportunity with high recall, but low precision.Conclusion
We conclude that the technique presented in this paper can be used in practice to automatically detect a number of anti-patterns that can be corrected by refactoring. 相似文献10.
