For example, a food delivery app includes a user dashboard, payment gateway interface, and restaurant management interface.
6. Data
Data defines the input, output, and storage of information in the software system. It ensures that information is processed, stored, and retrieved correctly. Moreover, proper data management improves system performance and security. Data helps in decision-making and generating useful reports. Poor data handling may lead to errors and data loss. Therefore, data is an important factor in defining software scope.
For example, a food delivery system stores customer details, restaurant data, order history, and payment records in a database.
7. Users
Users are the people who will interact with and use the software system. Their needs, skills, and expectations must be considered during development. Moreover, understanding users helps in designing user-friendly software. Different types of users may have different access levels and roles. Proper user identification improves system usability and functionality. Therefore, users are a key factor in defining software scope.
For example, a food delivery system includes customers who place orders, restaurant staff who manage food items, and administrators who control the system.
