As the new year approaches, Heidi Waterhouse emphasizes the importance of investing in internal technical documentation to enhance team performance and efficiency. Drawing on industry reports such as the "2021 Accelerate State of DevOps" and GitHub's "State of the Octoverse," she highlights that quality documentation can significantly boost productivity, improve security practices, and meet reliability targets. Waterhouse argues that while internal documentation is not something that can be bought, it serves as a crucial tool for reducing task friction, onboarding new employees, and preventing organizational bottlenecks. She suggests that making documentation an integral part of the software development process—similar to testing—and recognizing it in performance reviews can lead to higher-quality outcomes. Waterhouse also shares practical tips for starting or improving documentation efforts, such as conducting a documentation inventory or addressing the most urgent documentation gaps, and stresses the importance of routine maintenance to ensure accuracy. By making documentation a habitual part of workflows, organizations can leverage it as a powerful tool to align team efforts and preserve institutional knowledge.
