Guide: Software Release Management for Small Teams

Small teams frequently have to compete with bigger, more structured organizations who are capable of allocating more resources to project management, and software release management in particular. This means that small teams, or even individual developers, need to properly organize and execute their release process in order to keep up. In this article, Toptal Freelance Software Engineer Lucas Mancini focuses specifically on small startups, teams that don't have, or can’t afford, DevOps support, or teams that don't have a formal process defined for releasing new versions of their product. The author provides a suggested checklist method to manage releases, tailored to match his past experience working on different projects, together with some recommended best practices and guidelines.
