A well-built workflow naturally facilitates the ease of adding new members to a project, whether open source or a part of an organization. A simple tool suite and guide can be invaluable to those new members, and can help them to get over the hurdle of the first commit. Even a simple getting started README can go a long way, if properly maintained. Onboarding new members to a project is costly, and quality workflow can minimize the time spent by the new member. Bringing on new project members also requires some information and time from existing project members. If your project is an ongoing development effort, it's highly likely that you'll have some turnover, and saving time for existing members while shortening the time for new members to reach effectiveness should be a priority in your workflow.
