  8. 8. Notes for Developers/Authors <ul><li>Inspection results will not be used against developers at performance appraisal time. </li></ul><ul><li>Separate your ego from your work products, everyone do need reviews, you don’t have to become defensive during the inspection meeting. </li></ul><ul><li>Participants should be prepared adequately prior to the inspection meeting. </li></ul><ul><li>The items being inspected have to be documented adequately for a reviewer to be able to understand and critique them (this is actually an inspection result in itself). </li></ul><ul><li>Make sure you are properly trained for the inspection process. Reading this manual is of utmost importance before participation. </li></ul><ul><li>Author has to take the results of the inspection seriously and make the suggested changes. </li></ul><ul><li>Inspection meetings should not lose their focus. It should not wander into interesting discussions about technical solutions, and fail to cover the scheduled material. </li></ul><ul><li>The project schedule should incorporate time for inspections. </li></ul>
