Quality Assurance has a number of subdivisions; one of those being Quality Control (sometimes referred to as Software Testing). One of the, largely underrated, aspects of Quality Control is Verification.
We define Verification as being the static part of testing while Validation is the active part of testing where completed, compiled, and promoted code is being run using data and generating results. Verification refers to aspects of testing that do not involve actually executing the code and includes: Inspections, Walk-throughs and Reviews.

Since we do not need code, it is possible to launch into Verification much earlier in the process without waiting for code to be completed. As someone once pointed out, the first time you pick up some artifact from the project whether it be a document, minutes of meetings, a communication or even a conversation and start to look at it, you are performing your very first test of that system.

The three major subdivisions mentioned above differ in their degree of formality and where they may be applied. In general Inspections are the most formal of the processes and have a well developed methodology. Reviews can be formal or informal and can be done at various points depending on how necessary they are and what is the intent. Walkthroughs can be very informal and used with minimal effort and training.

The major impact of this type of testing is to discover issues, misconceptions, lack of clarity, incompleteness and misinterpretations as soon as possible.
While the concept is simple, the identification of the most cost-effective place to use Verification techniques is not always easy. There is no point in completing Verification processes without some end in view and a positive ROI.
