PLEASE HELP ME DEVELOP AN ACTIVITY DIAGRAM FOR THIS CASE STUDY

Develop an activity diagram based on the following narrative which describes a workflow for an application for a job promotion in an organisation. The applicant completes a Work Performance Review (WPR) document and submits it to his/her manager. The manager assesses the WPR document and decides whether to approve the applicants promotion. Where a promotion has not been approved by the manager, the manager sends the applicant written feedback on where the applicant needs to improve for promotion to take place. Where promotion has been approved by the manager, the manager informs the Human Resource Manager who will record details of the promotion and send written notification of the promotion to the applicant. The applicant files any documentation (described above) received as a result of the application process
