Hello, I need help with this assignment.1) Identify four use cases for the PSSM

Hello, I need help with this assignment.1) Identify four use cases for the PSSM staffing system and create a Use Case Diagram for each. The use cases should identify the name, actor, trigger, type, major inputs/outputs, major steps preformed and information required for each step.
The following template should be used for the submission; I shared it below. 2) Draw a Use Case Diagram in Visio with the four use cases, actors, and relationships.
3) Create a Context Diagram in Visio for the PSSM system.
The submission for Part I should be a Word document or .pdf (.doc/.docx/.pdf) containing the Use Case Diagram and Context Diagram in Visio. Hint: As a logical DFD, we are modeling the PSSM system which includes human actors (i.e. Contract Manager who reviews the terms and conditions of the contract) that are within the system. We don’t consider these human actors as external entities or external actors. They conduct process activities which act as part of the system. As you complete part I of the case, be thinking about how technology could improve the process/system for fulfilling contracts.
