Windows Application Deployment via Microsoft Intune: The Departmental Approach
Streamline your Windows application deployment with Microsoft Intune using our department-first strategy. This guide will help IT professionals efficiently manage applications across your organization while minimizing bloat and maximizing relevance.

Establish a Departmental Deployment Strategy
The foundation of effective application management in Intune starts with mapping your organizational structure to your deployment strategy. This approach ensures users receive only the applications they need for their specific roles.
Begin by analyzing each department's unique software requirements. Identify which applications are universally needed (like Microsoft 365) and which are department-specific (like QuickBooks for Finance). This targeted approach prevents unnecessary application bloat on devices and streamlines the user experience.
1
Map Department Needs
Document each department's core application requirements based on their workflows and responsibilities.
2
Identify Overlap
Determine which applications are needed across multiple departments (Teams, Office suite, etc.).
3
Define Unique Apps
List department-specific applications (QuickBooks, Adobe Creative Suite, etc.).
Organize Microsoft 365 Groups by Department
Microsoft 365 Groups serve as the foundation for your departmental deployment strategy. Create groups that mirror your organizational structure to simplify targeting and management.
Naming Convention
Use consistent naming like M365-Finance-Users, M365-HR-Users, M365-IT-Admins, and M365-Marketing-Users to clearly identify each group's purpose.
Assignment Control
Leverage these groups in Intune to control required deployments, available apps in Company Portal, and exclusions based on organizational roles.
Cross-Department Flexibility
This structure easily supports users who need access to applications across multiple departments through group membership.
Package Applications with Departmental Scope
Properly packaged applications are crucial for successful deployment through Intune. Each package should be prepared with departmental targeting in mind to facilitate precise deployment and management.
Include clear naming conventions that reflect the target audience, such as "Adobe – Acrobat Pro – 2025.001 – HR Only." This approach makes it immediately obvious which department each application is intended for, simplifying troubleshooting and auditing.
.intunewin Package Requirements
  • Silent install commands verified for unattended deployment
  • Accurate detection rules to prevent reinstallation
  • Department-specific version handling
  • Uninstall scripts for clean removal

Pro Tip: Test your silent install and uninstall commands thoroughly before packaging. Command-line parameters often vary between application versions, which can cause deployment failures if not validated.
Define Clear Application Taxonomy
A well-defined application taxonomy streamlines deployment decisions and helps maintain application hygiene across your organization. Categorize applications based on their purpose, target audience, and deployment requirements.
This structured approach prevents unnecessary installations and allows for more granular control over which applications are deployed to specific departments or roles.
Use Group-Based Assignments for Control
Group-based assignments are the cornerstone of departmental application deployment in Intune. They provide precise control over which applications are installed on which devices, based on user roles and departmental needs.
Always assign applications to the most specific group possible, rather than using broad "All Devices" assignments. This targeted approach minimizes unnecessary installations and reduces potential licensing costs, while ensuring users have access to the tools they need.
Slack
Assigned to M365-Marketing-Users as Available in Company Portal
VPN Client
Assigned to M365-IT-Admins as Required installation
Office Suite
Assigned to All Users via a parent M365 Group
Handle Shared Applications Across Departments
Many applications span multiple departments but may have different deployment requirements for each. Intune offers several methods to manage these shared applications efficiently.
Create Shared Groups
Build M365 groups that combine multiple departments (e.g., M365-Finance-and-HR) for applications used by specific combinations of teams.
Apply Intune Filters
Use filters to create exceptions or role-specific targeting within departments for more granular control.
Individual Assignments
Assign to each relevant departmental group individually when deployment requirements differ between departments.

Example: Power BI Desktop might be required for Finance and Operations departments, but only available as an optional installation for Marketing.
Testing Strategy per Department
1
Create Test Groups
Establish pilot groups for each department with technically proficient users who can provide meaningful feedback.
2
Validate Deployment
Test the installation experience, detection rules, and functionality within the department's workflow.
3
Gather Feedback
Collect user experiences and technical issues before proceeding to full deployment.
4
Adjust and Deploy
Make necessary adjustments based on feedback before rolling out to the entire department.
Thorough testing is essential before deploying applications to entire departments. Create a phased rollout approach that includes a small pilot group from each department to validate the deployment experience.
Establish "Ring 0" test groups for each department (e.g., M365-Marketing-Pilot) consisting of technical users who can provide valuable feedback. This approach allows you to identify and resolve department-specific issues before affecting all users.
Centralize Monitoring by Department
Effective monitoring is crucial for maintaining a healthy application environment. Intune provides robust reporting tools that can be segmented by departmental groups to track deployment success rates and identify issues quickly.
1
Track Deployment Status
Monitor installation success and failure rates per application, segmented by department to quickly identify patterns in deployment issues.
2
Review Installation Failures
Analyze department-specific installation failures to identify potential compatibility issues or policy conflicts unique to certain teams.
3
Monitor User Actions
Track user-initiated installations and uninstallations from Company Portal to understand department-specific software preferences and needs.

Export logs filtered by M365 Group membership to correlate user experiences and identify department-specific patterns that might not be obvious in aggregate data.
Ongoing Maintenance and Security Governance
Quarterly Reviews
  • Audit application versions across departments
  • Validate current department assignments
  • Identify and eliminate redundant applications
  • Update documentation with deployment groups and dependencies
Security Best Practices
  • Review app permissions per department
  • Audit installation attempts for suspicious activity
  • Implement Conditional Access for sensitive applications
  • Avoid broad-based assignments to reduce attack surface
Regular maintenance and strong security governance ensure your departmental deployment strategy remains effective over time. Schedule quarterly reviews to reassess application assignments, remove redundant software, and update documentation to reflect organizational changes.
