QUESTION 1
1.1 Give five core processes required in the development of any information system.
Requirement Gathering and Analysis: The first and most crucial stage in the development of
any information system is to understand and document the requirements of the system. This
process involves interacting with stakeholders to understand their needs, challenges, and
expectations from the system. It also involves analysing the current processes and identifying
areas for improvement to determine what functionalities and features the system should have.
Design: The design stage involves creating the architectural and technical blueprint…………..
