Shadow systems are IT systems, solutions, devices, or technologies used within an organization without the knowledge and approval of the corporate IT department1. They are often the result ofemployees trying to address specific functionality gaps in the organization’s official systems, such as the ERP system. However, shadow systems can pose significant risks to the organization, such as:

Data security and privacy breaches, as shadow systems may not comply with the organization’s security policies and standards, or may expose sensitive data to unauthorized parties2.

Data quality and integrity issues, as shadow systems may not synchronize or integrate with the organization’s official systems, or may create data inconsistencies or redundancies3.

Compliance and regulatory violations, as shadow systems may not adhere to the organization’s legal or contractual obligations, or may create audit or reporting challenges4.

Cost and resource inefficiencies, as shadow systems may duplicate or conflict with the organization’s official systems, or may consume more IT resources than necessary5.

The best way to reduce the risk associated with shadow systems is to implement an enterprise architecture (EA), which is a comprehensive framework that defines the structure, processes, principles, and standards of the organization’s IT environment6. By implementing an EA, the organization can:

Align the IT systems with the organization’s goals and strategy, and ensure that they support the business needs and requirements6.

Establish a governance structure and process for IT decision making, and ensure that all IT systems are approved, monitored, and controlled by the IT department7.

Enhance the communication and collaboration between the IT department and the business units, and ensure that the IT systems meet the expectations and preferences of the end users5.

Optimize the performance and efficiency of the IT systems, and ensure that they are scalable, flexible, and interoperable6.
