Dependencies in DevOps Survey 2021

While various empirical studies on the application of DevOps in practice exist, the state of application dependencies and their impact on the order of deployments has not been assessed yet. Such insight would indicate whether independent, cross-functional DevOps teams may deploy their applications independently or whether they need to coordinate. Further, in case coordination is required, we do not yet have insight into how such coordination is accomplished. To fill this gap, we perform a cross-sectional, self-administered, online questionnaire survey with IT professionals. This report documents the survey until April 15, 2021, including the analysis of the collected data. Further, we provide the dataset and the scripts for the paper and this report. <strong>Contents</strong> README.md: Overview and instructions on how to use this artifact. report.pdf: Survey report providing documentation, results and analysis of the survey until April 15, 2021. survey-data.csv: Survey dataset until April 15, 2021. analysis.zip: Analysis scripts for all statements and generation of all contents of report.pdf.

尽管现有诸多关于开发运维一体化（DevOps）实际应用的实证研究，但针对应用依赖关系及其对部署顺序的影响现状，目前尚未有相关评估。此类研究洞察将能够明确，独立的跨职能DevOps团队是否可以独立部署其应用，抑或需要开展协作协调。此外，若确实需要协作协调，目前我们仍未明确此类协调应如何实施。

为填补这一研究空白，我们面向IT专业人士开展了一项横断面、自主填写式的线上问卷调查。本报告记录了截至2021年4月15日的该项调查全过程，涵盖所收集数据的分析内容。此外，我们还提供了本报告及相关学术论文所使用的数据集与脚本文件。
