Due to the COVID-19 pandemic that broke out in 2020, companies switched to working from home on a large scale. Now, in 2025, many employees are working from home entirely or are only in the office irregularly. This has created a new working environment for many software professionals that resembles both the distributed software development (DSD) and open source software development (OSS) models. While working from home or a hybrid work environment is relatively new for many organizations (about 5 years), the challenges in DSD and OSS development have already been widely researched. Our research question focuses on best practices derived from OSS and DSD that solve the current challenges of working from home. We conducted a qualitative survey and interviewed fifteen individuals who have experience with DSD or OSS development. In this paper, we present fourteen proposed best practices for remote communication, collaboration, management, and tooling. Using the context-problem-solution pattern, we go beyond presenting high-level practices and suggest actionable details. The results of the study provide insights into this topic with high industry relevance. At the same time, the study contributes to existing academic research on working from home and the consequences of the COVID-19 pandemic. • Some OSS and DSD best practices solve current work from home challenges. • Proposed best practices are in management, communication, collaboration, and tooling. • Management - people-oriented management and promotion of autonomous decision making. • Collaboration - parallel processing of multiple tasks and status communication. • Communication - maintaining personal relationships and personal contact. • Tooling - There are a number of tools that best support distributed software development. • Our theory (actionable patterns) may improve work from home in software development.

The COVID-19 pandemic in 2020/2021/2022 and the resulting lockdowns forced many companies to switch to working from home, swiftly, on a large scale, and without preparation. This situation created unique challenges for software development, where individual software professionals had to shift instantly from working together at a physical venue to working remotely from home. Our research questions focus on the challenges of software professionals who work from home due to the COVID-19 pandemic, which we studied empirically at a German bank. We conducted a case study employing a mixed methods approach. We aimed to cover both the breadth of challenges via a quantitative survey, as well as a deeper understanding of these challenges via the follow-up qualitative analysis of 15 semi-structured interviews. In this article, we present the key impediments employees faced during the crisis, as well as their similarities and differences to the known challenges in distributed software development (DSD). We also analyze the employees’ job satisfaction and how the identified challenges impact job satisfaction. In our study, we focus on challenges in communication, collaboration, tooling, and management. The findings of the study provide insights into this emerging topic of high industry relevance. At the same time, the study contributes to the existing academic research on work from home and on the COVID-19 pandemic aftermath.
