Answer to Question 1

The elements that must be designed when building an information system include the following: (1 ) human-computer interface, (2 ) databases and files, and (3 ) processing and logic.

Designing the human-computer interface: Just as people have different ways of interacting with other people, information systems can have different ways of interacting with people. A human-computer interface (HCI) is the point of contact between a system and users.
Designing databases and files: To design databases and files, a systems analyst must have a thorough understanding of an organization's data and informational needs.
Designing processing and logic: The processing and logic operations of an information system are the steps and procedures that transform raw data inputs into new or modified information.

Answer to Question 2

Organizations need to be prepared for when something catastrophic occurs. The most important aspect of preparing for a disaster is the creation of a business continuity plan, which describes how a business resumes operation after a disaster. A subset of the business continuity plan is the disaster recovery plan, which spells out detailed procedures for recovering from systems-related disasters, such as virus infections and other disasters that might cripple the IS infrastructure. When planning for disaster, two objectives should be considered by an organization: recovery time objectives and recovery point objectives. Recovery time objectives specify the maximum time allowed to recover from a catastrophic event. Recovery point objectives specify how current the backup data should be.
