What can analysis of a document tell you about the future system?

What will be an ideal response?

In documents, you can find information about the following:
• Problems with existing systems
• Opportunities to meet new needs if only certain information or information processing were available
• Organizational direction that can influence information system requirements
• Titles and names of key individuals who have an interest in relevant existing systems
• Values of the organization or individuals who can help determine priorities for different capabilities desired by different users
• Special information processing circumstances that occur irregularly that may not be identified by any other requirements determination technique
• The reason why current systems are designed as they are, which can suggest features left out of current software, which may now be feasible and more desirable
• Data, rules for processing data, and principles by which the organization operates that must be enforced by the information system
