I am the program maintainer/demonstrator. According to my project role, I must do demonstration of project execution, (e.g., milestone reports, project tracking, etc.) and Evidence of effective use of version control system. I need to work on only Project 1: develop an IT software system to manage customers and allow them to book flights, manage flight reservations, seat selections, purchasing in-flight services such as food and drinks (check pg.4 of project description). I need 30%-50% of the work by 06/20/2021 (coming Wednesday), because it is just an initial submission. And then the rest of it by 14/10/2021 when the whole assignment is due. I have attached the program to help understand start with the task. I can also attach the WBS structure. Please let me know if you need anything else, I can ask my group mates and help.
