+## Work on heterogeneous PVPs
+
+Usecase of security checks against system (Github and Managed Kubernetes clusters) by multiple PVPs (Auditree, Kyverno, and OCM Policy).
+
+![heterogeneous](https://github.com/oscal-compass/compliance-to-policy/assets/113283236/bb64f81a-986c-41fa-83c6-4e7e9165af76)
+
+#### Steps
+1. (Optional) Create OSCAL Component Defintion including multiple PVPs as validation components
+    - [component-definition.csv](/plugins_public/tests/data/heterogeneous/component-definition.csv)
+1. Generate PVP policies from the OSCAL Component Definition
+    ```
+    python samples_public/heterogeneous/compliance_to_policy.py \
+      -c ./plugins_public/tests/data/heterogeneous/component-definition.json \
+      -o ./policies
+    ```
+    1. Policies for each PVP are generated
+        ```
+        $ tree -L 2 policies
+        policies
+        ├── auditree
+        │   └── auditree.json
+        ├── kyverno
+        │   ├── allowed-base-images
+        │   └── disallow-capabilities
+        └── ocm
+            ├── kustomization.yaml
+            ├── parameters.yaml
+            ├── policy-deployment
+            ├── policy-disallowed-roles
+            ├── policy-generator.yaml
+            └── policy-high-scan
+        ```
+1. (Optional) Collect policy validation results from system
+    - Example all PVP results are located in [/plugins_public/tests/data](/plugins_public/tests/data).
+1. Generate OSCAL Assessment Results from PVP results 
+    ```
+    python samples_public/heterogeneous/result_to_compliance.py \
+      -c ./plugins_public/tests/data/heterogeneous/component-definition.json \
+      -r ./plugins_public/tests/data > assessment-results.json
+    ```
+1. OSCAL Assessment Results is not human readable format. You can see the merged report in markdown by a quick viewer.
+    ```
+    c2p tools viewer \
+      -cdef ./plugins_public/tests/data/heterogeneous/component-definition.json \
+      -ar assessment-results.json
+    ```
+    e.g. [result.md](/docs/public/heterogeneous.result.md)
