Optimal project feature weights in analogy-based cost estimation: improvement and limitations
TL;DR: This work proposes to allocate separate weights to each project feature and to find the optimal weights by extensive search, and finds that this method increases estimation accuracy and reliability, reduces the model's volatility and, thus, is likely to increase its acceptance in practice.
Journal ArticleDOI
Software reviews, the state of the practice
TL;DR: A 2002 survey found that many companies use software reviews unsystematically, creating a mismatch between expected outcomes and review implementations, suggesting that many software practitioners understand basic review concepts but often fall to exploit their full potential.
Proceedings ArticleDOI
PlanningLines: novel glyphs for representing temporal uncertainties and their evaluation
TL;DR: Main results are that PlanningLine users make fewer mistakes and are faster in conducting tasks than users of a traditional visualization technique.
Journal ArticleDOI
Investigating the defect detection effectiveness and cost benefit of nominal inspection teams
Stefan Biffl,Michael Halling +1 more
TL;DR: An initial baseline of inspection performance with regard to process diversity and effort in inspection teams is provided and further studies on the topic of time usage with defect detection techniques and its effect on inspection effectiveness in a variety of inspection contexts are encouraged.
Proceedings ArticleDOI
A case study on value-based requirements tracing
Matthias Heindl,Stefan Biffl +1 more
TL;DR: In this article, the authors present a case study on value-based requirements tracing (VBRT) that systematically supports project managers in tailoring requirements tracing precision and effort based on the parameters stakeholder value, requirements risk/volatility, and tracing costs.
