Abstract

The purpose of this qualitative multiple case study is to research the current causes to cost estimation errors and revisit the research question of a well published quantitative study to explore whether responses would be consistent using qualitative methodology. Both overlaps and deviations are to be expected as a result of this comparison. The focus of this paper is on differences where new issues are likely to be found. The 8 resulting cross case cost estimation inhibitors validate 7 out of 16 issues found in the quantitative study. They are also related to the theory within and outside the area of software engineering resulting in five underlying software cost estimation inhibitors and providing a deeper understanding for the snapshot of the current causes of cost estimation errors reported by the practitioners. Lastly, the question of the practitioners' ability to report upon software cost estimation inhibitors is discussed. We argue that there might be causes of cost estimation errors that practitioners might be unwilling to reveal or might even be completely unaware of. Thus, they might unconsciously be providing researchers with invalid data.
还有其他成本估算障碍吗?
本定性多案例研究的目的是研究成本估算误差的当前原因,并重新审视一项已发表的定量研究的研究问题,以探索使用定性方法的反应是否一致。由于这种比较,重叠和偏差都是可以预料到的。本文的重点是可能发现新问题的差异。8个交叉案例成本估算抑制剂验证了定量研究中发现的16个问题中的7个。它们还与软件工程领域内外的理论相关,这些理论导致了五个潜在的软件成本估算抑制因素,并为从业者报告的成本估算错误的当前原因提供了更深入的理解。最后,讨论了从业者报告软件成本估算抑制因素的能力问题。我们认为,可能存在从业者不愿意透露或者甚至完全不知道的成本估算错误的原因。因此,他们可能会无意识地向研究人员提供无效的数据。
