+Inspector Design Guideline
+==========================
+
+.. NOTE::
+ This is spec draft of design guideline for inspector component.
+ JIRA ticket to track the update and collect comments: `DOCTOR-73`_.
+
+This document summarize the best practise in designing a high performance
+inspector to meet the requirements in `OPNFV Doctor project`_.
+
+Problem Description
+===================
+
+Some pitfalls has be detected during the development of sample inspector, e.g.
+we suffered a significant `performance degrading in listing VMs in a host`_.
+
+A `patch set for caching the list`_ has been committed to solve issue. When a
+new inspector is integrated, it would be nice to have an evaluation of existing
+design and give recommendations for improvements.
+
+This document can be treated as a source of related blueprints in inspector
+projects.
+
+Guidelines
+==========
+
+Host specific VMs list
+----------------------
+
+TBD, see `DOCTOR-76`_.
+
+Parallel execution
+------------------
+
+TBD, see `discussion in mailing list`_.
