Free registration required

Executive Summary

Coders write abundant amounts of SAS code for ad hoc analysis. This code is not usually intended for use in a full scale production system, but it is still critical that it be validated. Specifically, the code should meet the necessary business requirements, be syntactically correct and have the output reviewed. What makes this challenging is coders must often do this without the benefit of external testing/peer review and usually in a short time frame. This paper presents a method and checklist for reviewing the work that will ensure each of these points are covered. It is easy to remember and implement. The content presented here is not specific to any particular SAS platform or version. It is intended for beginning and intermediate SAS coders.
