Service Department Visits

This is a demo Vaadin application created with Spring Boot. It is a queue management system allowing customers to reserve time in queue and specialists to accept/complete/cancel visits.

Functionality

2 roles are supported:

• Customer (unauthenticated user)
• Specialist (authenticated user)

Customer

Unauthenticated users can interact with "Book Time" screen where they can choose a specialist and book a visit in queue. Once booked, they get a reservation code and approximate waiting time which is currently calculated based on formula

Wait Time = Average visit time x Earlier visits, where

• Earlier visits is the number of active/waiting visits before this visit
• Average time is based on the following conditions:
  • If a specialist has some completed visits, average time is calculated for that specialist
  • Otherwise, average time is calculated for all specialists
  • If there are no completed visits by any specialist, system defaults to 7 minutes. Additionally, customers can cancel the visit.

Specialist

Specialists must authenticate at /login endpoint. Specialist accounts must be created by manual data insertion into database. For simplicity purposes, system is already pre-populated with the following specialists and their credentials:

• gabrielle.patel@nfq.com // test
• brian.robinson@nfq.com // test
• eduardo.haugen@nfq.com // test

Once authenticated, Service Department link appears in the navigation menu. Service department screen allows the specialist to:

• View up to 6 visits in queue (1 active + 5 waiting)
• Accept or Cancel next customer in line. Only 1 visit can be "active" (accepted).
• Complete or Cancel current visit. Only active (accepted) visit can be completed.

Either specialist action immediately updates the screen.
