ORM conceptual Diagram needs to be drawn for the case below. I am struggling to figure out how to illustrate the relationship of the team members within the project and how that links back to the Staff.

  

A business called ProjectsRus hires project teams to develop and implement technology for a client. The project team is suitably qualified staff who fulfil the project roles of project manager (PM). software developer (SD), system analyst(SA), database developer(DD), user interface developer (UID), and tester(T). Other project roles are possible, and a staff member can have a different role in different projects. For example, you are the system analyst in one project, and in another project, you are a project manager. ProjectsRus maintains information about their project team staff members and the projects performed for clients. The following table shows the list of project team staff members details including their employment start and finish dates.

A project team staff member has only one role in the project. As shown in the examples, the full names of the roles are not used in a project charter.
