Abstract: Identity Access Management has become a strategic capability for growing medium-sized companies. As organizations expand, collaborate with external partners and operate across multiple digital systems, access rights must be managed in a transparent, secure and scalable manner. This paper outlines how a role-based authorization model can reduce complexity and improve governance across Microsoft 365, HR tools, and project controlling, CRM and finance applications. The proposed model is based on Role-Based Access Control and combines baseline roles, functional roles and temporary project roles. This modular structure supports least-privilege access, improves auditability and enables automated Joiner-Mover-Leaver processes. The paper further discusses stakeholder involvement, governance responsibilities, compliance requirements and the economic value of standardized access management. The findings show that a business-oriented role model is not merely a technical instrument but a strategic enabler for secure growth, operational efficiency and sustainable digital governance.
