erasEwaste Use Cases

Volunteer Use Cases

1. Login_Layout

Identification: An erasEwaste volunteer logs into the system with his name and his ID given to him by his manager. He then clicks ‘Login’.

Primary Actors: The user (volunteer) and the manager are the primary actors. The manager sets up the volunteer’s account and the volunteer signs in.

Stakeholders: The stakeholders include the volunteer, the manager, and Property Control. The manager can track his volunteers, the volunteers can log their work, and Property Control can have records for itself and recipients.

Preconditions and Main Success Scenario: Having the manager set up the volunteer’s account is the first precondition and making the volunteer aware of his login information is the second.

2. Title_Layout

Identification: This screen welcomes the volunteer after logging in and gives them the option to ‘Enter New Record’ or click ‘Find Mode'. ‘New Record’ allows a user to register a product that came in from Property Control. ‘Find Mode’ allows the user to search through products that were already registered. The user also has the option to ‘Logout’ in the top right corner of the page.

Primary Actors: The volunteer is the primary actor. The volunteer can access ‘Enter New Record’ and ‘Find Mode’.

Stakeholders: The stakeholders here are the erasEwaste volunteers and Property Control.

Preconditions and Main Success Scenario: The volunteers must have an account and be logged in to get to this screen.

3. Products_Layout

Identification: On this screen the erasEwaste volunteer is welcomed and can register a product into the database. He first chooses a ‘Product Type’ from a dropdown list, then determines the ‘Product Quality’ and selects the appropriate radio button, then determines whether or not the product passed ‘Final Inspection’ and selects the appropriate radio button. The volunteer then may add any ‘Additional Notes’ in a comment box. The final step here is to provide the volunteer’s ‘Signature’ with his finger on the tablet itself. After all of this information is input, a QR code will be generated on the right side of the screen unique to that product. The volunteer may go back by clicking ‘Home’. The volunteer can also ‘Create New Record’ or ‘Delete Record’. Clicking the ‘Next’ button takes the volunteer to a screen with the product's QR code. The user may also ‘Logout’ in the top right corner.

Primary Actors: The volunteer is the primary actor who determines the data on this screen.

Stakeholders: The stakeholders are the erasEwaste volunteers, managers, Property Control and end recipients.

Preconditions and Main Success Scenario: The preconditions are that the volunteer received a product. If the product received is a computer, then the volunteer must do a hardware test and a software update.

Alternate Flow: If a computer fails the hardware test, it is to be documented into the database. The product is to then undergo hardware testing again and proper documentation. If a product goes through three hardware tests/documentation and still fails, the erasEwaste volunteer is to strip the computer for valuable parts to be used when refurbshing other products. The remaining scraps are to be transferred to a landfill. We aim to erasEwaste as much as possible while limiting the effect on the environment.

4. QR_Code

They are shown the product’s unique QR code and are given the option to click ‘Finish’, which takes them back to the Volunteer Home page, or click ‘Logout’.
