In my company, I work in a project-based/matrix-based combination of an organization. There are multiple projects going on at a time and each project has it’s team. However, the teams are made up of staff from different departments (R&D, regulatory, marketing, tech leads) who also are part of at least one other project for their respective role. I’ve noticed particularly that there is limited knowledge sharing between different projects since each one runs independent of another. For each project, there is usually a scientific lead/engineer running the specific project but another manager we must report to that manages all persons of a specific role (for example, all R&D engineers). It can be messy at times, with communication lacking between project members, but it does help to meet every week as a project team to discuss progress.
