Group 4: Roles
The subgroups of a team are roles. When you want to earn money you have to be assigned to a role. When you are assigned to a role by your team captain, you'll get access to the objective group you applied for. That is the subgroup of the role. In the objective group, you can see the open tasks and sign in to one of them. Tasks are the subgroups of objectives. For example, you are a member of the design team and your team captain assigned you the role of UX designer based on your proposal to contribute to the objective 'Create the front end design of the Android app.' You now have access to the group of that objective and all documentation that belongs to that mission. In that group you then notify the Mission Leader of your 'arrival'. He/she will then assign you to a task that fits your skillset, level and experience. The role of the Mission Leader will be explained in group 5: objective.
Payment and Roles
If you are a member of a Role group you also know how much you will get paid once you are working on a task. A role has a fixed hourly rate. Therefore, the biggest responsibility of the team captain is to manage the roles. The team captain manages the budget of the team and he/she should know what kind of roles are needed to get the job done
