+# Scenario: Creating Users with Specific Requirements
+
+## Original Problem
+- Create a new user called 'analyst1' with home directory '/home/analyst1'
+- Create a group called 'datateam'
+- Add 'analyst1' to 'datateam'
+- Create a directory '/data/reports' owned by 'datateam' with SGID set
+- Ensure members of 'datateam' can read/write, others can only read
+- Set password expiry for 'analyst1' to 90 days
+
+## Environment
+- OS Version: RHEL 9.5
+- Initial State: No user 'analyst1' exists
+- Required Outcome: User 'analyst1' created with specific requirements
+
+## Solution Steps
+1. Step 1 - Create the user 'analyst1'
+   ```bash
+   sudo useradd -m -d /home/analyst1 analyst1
+   ```
+   This creates the user 'analyst1' with a home directory '/home/analyst1'
+
+2. Step 2
+   ```bash
+   sudo groupadd datateam
+   ```
+   This creates the group 'datateam'
+
+3. Step 3 - Add 'analyst1' to 'datateam'
+   ```bash
+   sudo usermod -aG datateam analyst1
+   ```
+   This adds 'analyst1' to the 'datateam' group
+
+4. Step 4 - Create the directory '/data/reports' owned by 'datateam' with SGID set
+   ```bash
+   sudo mkdir -p /data/reports
+   sudo chown :datateam /data/reports
+   sudo chmod 2775 /data/reports
+   ```
+   This creates the directory '/data/reports' owned by 'datateam' with SGID set
+
+5. Step 5 - Ensure members of 'datateam' can read/write, others can only read 
+   ```bash
+   sudo chmod 2775 /data/reports
+   ```
+   This ensures members of 'datateam' can read/write, others can only read
+
+6. Step 6 - Set password expiry for 'analyst1' to 90 days
+   ```bash
+   sudo chage -E $(date -d '90 days' +%Y-%m-%d) analyst1
+   ```
+   This sets the password expiry for 'analyst1' to 90 days
+
+## Verification
+Commands used to verify the solution works correctly
+
+## Key Learnings
+- Understanding of useradd, groupadd, usermod, mkdir, chown, chmod, chage commands
+- Importance of verifying user creation
+- Importance of setting password expiry
+
+## Additional Notes
+> [!NOTE]
+> This scenario is a good example of how to create a user with a specific home directory, add them to a group, create a directory owned by the group with SGID set, and set password expiry.
