Discuss THREE circumstances that could necessitate the maintenance of information systems by an organization.

Technological Advancements: One of the main circumstances that necessitate the maintenance of information systems is the rapid pace of technological advancements. As new technologies emerge, organizations need to update their information systems to stay competitive and efficient. This could involve updating software, replacing outdated hardware, or implementing new security measures to protect against cyber threats.

Organizational Changes: Changes within the organization can also necessitate the maintenance of information systems. For example, if a company expands its operations, merges with another company, or changes its business processes, it may need to update its information systems to support these changes. This could involve adding new functionalities, integrating systems, or reconfiguring existing systems.

Regulatory Compliance: Organizations are often subject to various regulations that dictate how they manage and protect their information. If these regulations change, or if the organization falls out of compliance, it may need to maintain its information systems to meet these regulatory requirements. This could involve implementing new controls, updating policies and procedures, or conducting audits to ensure compliance.
