+Performance Trending (PT)
+`````````````````````````
+
+CSIT PT runs regular performance test jobs measuring and collecting MRR
+data per test case. PT is designed as follows:
+
+1. PT job triggers:
+
+   a) Periodic e.g. twice a day.
+   b) On-demand gerrit triggered.
+
+2. Measurements and data calculations per test case:
+
+  a) Max Received Rate (MRR) - for each trial measurement,
+     send packets at link rate for trial duration,
+     count total received packets, divide by trial duration.
+
+3. Archive MRR values per test case.
+4. Archive all counters collected at MRR.
+
+Performance Analysis (PA)
+`````````````````````````
+
+CSIT PA runs performance analysis
+including anomaly detection as described above.
+PA is defined as follows:
+
+1. PA job triggers:
+
+   a) By PT jobs at their completion.
+   b) On-demand gerrit triggered.
+
+2. Download and parse archived historical data and the new data:
+
+   a) Download RF output.xml files from latest PT job and compressed
+      archived data from nexus.
+   b) Parse out the data filtering test cases listed in PA specification
+      (part of CSIT PAL specification file).
+
+3. Re-calculate new groups and their averages.
+
+4. Evaluate new test data:
+
+   a) If the existing group is prolonged => Result = Pass,
+      Reason = Normal.
+   b) If a new group is detected with lower average =>
+      Result = Fail, Reason = Regression.
+   c) If a new group is detected with higher average =>
+      Result = Pass, Reason = Progression.
+
+5. Generate and publish results
+
+   a) Relay evaluation result to job result.
+   b) Generate a new set of trend summary dashboard, list of failed
+      tests and graphs.
+   c) Publish trend dashboard and graphs in html format on
+      https://docs.fd.io/.
+   d) Generate an alerting email. This email is sent by Jenkins to
+      csit-report@lists.fd.io
