+
+1. **Data Preparation:** Team A generates CSV data adhering to a predefined format and places the file in a shared
+   location accessible to Team B (e.g., a shared repository or cloud storage).
+
+2. **Notification:** Team A notifies Team B that the data is ready via corporate communication channels (email, chat,
+   task management system).
+
+3. **Validation:** Team B uses predefined validation rules stored in the repository to check the CSV file for accuracy
+   and integrity before importing. This includes verifying date formats, numerical values, and the presence of required
+   columns.
+
+4. **Data Import:** After successful validation, Team B imports the data from the CSV file into their system for further
+   processing.
+
+5. **Error Handling:** If validation identifies errors, the process halts, and Team B provides feedback to Team A for
+   data correction.
+
+**Why Validation is Necessary:**
+
+- **Reduce Errors:** Validating data before import minimizes the likelihood of errors, enhancing data quality.
+- **Efficiency:** Prevents time loss on manual error correction post-import.
+- **Data Consistency:** Ensures data meets the expectations and requirements of Team B, facilitating accurate processing
+  and analysis.
+- **Automation:** Storing validation rules in the repository eases the process of checking automation and simplifies
+  updating validation criteria.
