QualifiedFor.com allows you to define multiple personnel roles that can be assigned to a person, and contain required and prefered qualifications that the person must hold in order to fulfil the role.
Personnel roles can be entirely configured by the user, but for example a Role of "Driver" might require an active "Driver" qualification and also prefer a "Defensive Driving" qualification.
People with the "Driver" role assigned will show with a pair of or icons to indicate the status of the persons qualifications in relation to their assigned role.
