Question 1: (30 Marks) This question concerns the development of a small software system. The scenario below outlines the problem domain. This description is not complete, but it contains all the information needed to answer the questions from 1.1 to 1.10. [Any answer not related to the scenario will be given ZERO mark]. Due to COVID19 pandemic, organizations started applying restrictions and rules for visitors as part of safety measures. It is worth thinking about developing a visitor management system.

The staff schedule meeting, cancel meetings and send emails. The managers of each department approves the meeting schedule after checking their duty schedule. The system administrator does the system maintenance which includes system shut down and error reports. Before developing the application, there is a need to identify various factors such as the software architecture, deployment platform, project risks and assumptions etc. In addition, the system should provide a user friendly web interface to the users and should be able to access using various devices. The system is expected to be functioning within half a year. The system shall operate in accordance with the operating country's monitoring agency and laws. 1.1 2 Marks Identify any TWO requirement constrains mentioned in the scenario.
