+Integration with Yardstick
+**************************
+
+Problem description
+===================
+
+For each specified QPI [1]_, QTIP needs to select a suite of test cases and collect
+required test results. Based on these results, Qtip calculates the score.
+
+Proposed change
+===============
+Qtip has a flexible architecture [2]_ to support different mode: standalone and agent.
+It is recommended to use **agent mode** to work with existing test runners. Yardstick will
+act as a runner to generate test result and trigger Qtip agent on the completion of test.
+
+
+Work Items in Yardstick
+-----------------------
+
+1. Create a customized suite in Yardstick
+
+Yardstick not only has many existing suites but also support customized suites. Qtip could
+create a suite named **Qtip-PoC** in Yardstick repo to verify workflow of Qtip agent mode.
+
+2. Launch Qtip in Yardstick
+
+Whether to launch Qtip will be determined by checking the existence of OS environment
+variable *QTIP*. If it exists, Qtip will be launched by using Yardstick CLI
+`yardstick plugin install` [3]_.
+
+3. Yardstick interacts with Qtip
+
+See
+`Yardstick-Qtip+integration <https://wiki.opnfv.org/display/yardstick/Yardstick-Qtip+integration>`_
+for details.
+
+Work Items in Qtip
+------------------
+
+1. Provide an API for Yardstick to post test result and environment info
+
+After completing test execution, Yardstick will post test result and enviroment info with
+JSON format via QTIP API. See
+`Yardstick-Qtip+integration <https://wiki.opnfv.org/display/yardstick/Yardstick-Qtip+integration>`_
+for details.
+
+2. Parse yardstick test result
+
+When Qtip agent receive Yarstick test result and enviroment info, Qtip agent will extract
+metrics which is definded in metric spec configuration file. Based on these metrics, Qtip
+agent will caculate QPI.
+
+3. Provide an API for querying QPI
+
+Qtip will provide an API for querying QPI. See
+`Yardstick-Qtip+integration <https://wiki.opnfv.org/display/yardstick/Yardstick-Qtip+integration>`_
+for details.
