Then a “summary ” gives an overview of the methods in the SOP, with special attention to what is likely to be of greatestinterest to readers. Next, the SOP includes the “training qualifications ” of the people involved in applying the method and the “equipment and supplies ” needed to perform the SOP. Finally, the “method ” is detailed, including specific numbered steps.
