Question: I'm not sure if I should add something as an OBS unit, role or skill (e.g., "Java Developer"). What's best practice here?
Answer: One consideration here is that when adding resources to a project, you can filter your resources by name, role and skill, but not by OBS unit. So if you want to filter for something (e.g., "Java Developer") when searching for resources, it's best to add it as a role or skill.
