# The Wait-Test-Deploy Framework: A Phased Rollout Strategy for Enterprise Apps

In the modern endpoint environment, the “Update Day Disaster” is a recurring threat to organizational productivity. When a third-party vendor releases a software update, it often contains unforeseen bugs, hardware incompatibilities, or security regressions that can paralyze a 10,000-device fleet instantly. Relying on “Auto-Updates” is no longer a viable strategy for enterprise stability; it creates a chaotic software environment where troubleshooting becomes impossible due to version fragmentation.

To combat this, we implement the **Wait-Test-Deploy** framework. This is a disciplined release management logic designed to transition the organization from reactive firefighting to proactive **Global Version Control.** By enforcing intentional delays and tiered validation phases through the **Hexnode UEM,** IT administrators can ensure that every device regardless of location or department remains on a known, stable, and tested software baseline.

1. The Patching Matrix (SLA & Risk Levels)
----------------------------------------------

Updates are categorized by risk. The “Wait” period allows for third-party bug discovery before the **Policy Association** for the internal fleet begins.

Execution Steps in Hexnode UEM
---------------------------------

### Step A: Configure the “Wait” (Update Deferral)

- **For macOS Apps:** Navigate to **Policies > New Policy > macOS > Patches & Updates > App Updates**. Use **Maintenance Window** to restrict when app patches are applied, ensuring they only occur during approved testing or deployment hours.
- **For Windows Apps:** Navigate to **Policies > Windows > Patches & Updates > App Updates**. Configure settings to control when app updates are enforced, preventing the Microsoft Store or local installers from updating until the “Test” phase is finalized.
- **For Android (Managed Google Play Apps):** Navigate to **Policies > Android > App Management > Required Apps**. Configure **Update apps only over Wi-Fi** to ensure large patches do not trigger over cellular data during the observation phase.

### Step B: The “Test” Phase (Pilot Deployment)

1. **Group Creation:** Navigate to **Manage > Device Groups**. Create a **Custom Device Group** or **Dynamic Device Group** named **“Pilot – Alpha Testers.”**
2. **Targeted Deployment:**
    - For **Enterprise Apps (MSI/APK/PKG):** Upload the new version to the **App Inventory**.
    - **Policy Assignment:** Go to **Policies > App Management > Required Apps**. Add the app and **Associate** this policy only with the “Pilot” Device Group.
3. **Monitoring:** Check **Action History** for real-time deployment logs.

### Step C: The “Global Deploy” (Production)

1. Once the pilot is validated, navigate to your **Production Policy**.
2. **Policy Sync:** Perform a **Policy Refresh**. Hexnode will automatically trigger the **Global Push** to the remaining 95% of devices.

3. Troubleshooting & Rollbacks
----------------------------------

If a “Test” phase reveals a critical bug, initiate the following:

- **Halt Deployment:** Immediately **Disassociate** the Pilot Policy from the affected Device Group.
- **Version Pinning & Downgrade:**
    - In the **App Inventory**, select the application and ensure the previous stable version (e.g., v4.2.0) is the active **Managed Version.**
    - For **Android Enterprise,** enable **Enforce App Downgrade** within the policy to force devices back to the stable release.
- **Admin Communication:** Use the **Messenger** service within Hexnode to send a **Broadcast Message** to the Pilot Group, notifying them that a rollback is in progress.
