"Among its findings are:
"1. The Alcotest Software Would Not Pass U.S. Industry Standards for Software Development and Testing: The program presented shows ample evidence of incomplete design, incomplete verification of design, and incomplete "white box" and "black box" testing. Therefore the software has to be considered unreliable and untested, and in several cases it does not meet stated requirements. The planning and documentation of the design is haphazard. Sections of the original code and modified code show evidence of using an experimental approach to coding, or use what is best described as the "trial and error" method. Several sections are marked as "temporary, for now". Other sections were added to existing modules or inserted in a code stream, leading to a patchwork design and coding style.
"The software development life-cycle concept is governed by one of the nationally and internationally recognized development standards to prevent defects from entering the software during the design process, and to find and eliminate more defects as the software is coded, tested, and released to the field. This concept of software development using standards requires extensive and meticulous supporting data, and notations in source files, and a configuration management system. None of this methodology is evident in the Alcotest code. Further, the decision method of how to allocate the architecture and assignment of tasks does not match any of the software standards. This further substantiates that software development standards were not used to verify or test the software, including the ISO 9000 family of standards."
