“Stack Tester’s Fingerprint”

The last thing a buyer wants is to fail because of the tester. The stack test should be void of the tester's fingerprints. Having overseen stack testing for more than 10 years, I have found the following disturbing facts:

*The lack of understanding of what the stack tester does, leaves the buyer listening to the fastest talker. Without knowledge, the buyer can only ask the tester if this is the best (right) way and if it was a job well done.

*The financial squeeze on the stack sampling community has produced a lowering in quality of the average test. The buyers’ concept is to “hire local” to save on cost and lower response time. This limits the playing field and quality.

*The increase in the volume of stack tests has also reduced the quality of the stack tests. This is because the State reviewers are overloaded and cannot help in quality control. Also, the stack testing new hires are promoted more rapidly.

*Quality is not just determined by the price or the company hired, but by the people on site. The most critical person in a stack test is the on site test manager. The company will provide organization, available equipment, and report organization, but it is the people on site that collect the data. Garbage in is garbage out. It is better to get an ugly report then ugly data.

The buyer's concerns as to quality usually start after discovering the test has failed. Concern should have started with writing the protocol. Once a tester is on site, the majority of the cost of the job has been expended. This is the time to make sure the tester does the job they were hired to do. Reviewing the report only is an attempt to disqualify it.
