Research doesn’t begin with a published paper—it starts with a question, a plan, and a process that sometimes remains invisible to others. At the Center for Open Science (COS), we use the term lifecycle open science (LOS) to describe an approach to making the record of your work visible: research with publicly accessible plans, outputs (such as data, materials, and code), and outcomes that are linked and findable across the research lifecycle. Lifecycle open science begins with a prospective study plan and preregistration to set a clear, time-stamped foundation for your research.
