Prioritize the implementation of a single sign-on (SSO) solution for all resources, as it simplifies user access but may not fully address compliance and scalability needs.

Design a solution that provides seamless access to both cloud and on-premises resources, integrates with existing systems for centralized management, and includes multi-factor authentication (MFA) to enhance security while meeting compliance standards.

Focus solely on implementing the IAM solution for on-premises resources to reduce complexity, ignoring the cloud resources which could limit future scalability and flexibility.

Implement a decentralized IAM solution that allows each department to manage their own access controls, potentially leading to inconsistencies in security policies and compliance violations.
