经验软件工程已经产生了稳定的基于证据的结果，这些结果涉及影响重要结果的因素，如成本，质量和间隔。然而，程序员通常对这些问题也有强烈的先验意见。这些意见很重要，因为开发人员是受过严格训练的专业人士，他们的信念无疑会影响他们的实践。与循证医学一样，向开发人员传播经验研究结果是确保研究结果影响实践的关键步骤。在本文中，我们描述了一个案例研究，在微软的开发人员的信念，这些信念的关系，这些开发人员的工作项目的实际经验数据。我们的发现是：a）程序员确实对某些主题有很强的信念，B）他们的信念主要是基于个人经验形成的，而不是基于实证研究的结果，c）信念可以随每个项目而变化，但不一定与该项目中的实际证据相对应。我们的研究结果表明，应采取更多的努力，传播实证研究结果的开发人员和更深入的研究，在软件实践中的信念和证据的相互作用是必要的。
Empirical software engineering has produced a steady stream of evidence-based results concerning the factors that affect important outcomes such as cost, quality, and interval. However, programmers often also have strongly-held a priori opinions about these issues. These opinions are important, since developers are highlytrained professionals whose beliefs would doubtless affect their practice. As in evidence-based medicine, disseminating empirical findings to developers is a key step in ensuring that the findings impact practice. In this paper, we describe a case study, on the prior beliefs of developers at Microsoft, and the relationship of these beliefs to actual empirical data on the projects in which these developers work. Our findings are that a) programmers do indeed have very strong beliefs on certain topics b) their beliefs are primarily formed based on personal experience, rather than on findings in empirical research and c) beliefs can vary with each project, but do not necessarily correspond with actual evidence in that project. Our findings suggest that more effort should be taken to disseminate empirical findings to developers and that more in-depth study the interplay of belief and evidence in software practice is needed.
