CHAPTER ◆ 23

The product team must be confident that the development team has built the hardware

and software in a quality manner. The product team can accomplish this through inde-

pendent verification and validation; the term quality assurance (QA) generally refers to

these activities. Systematic auditing of both the development process and the developed

products will ensure that development has been done properly and that the software and

hardware components meet specifications and quality attribute requirements. QA processes

naturally escalate development issues to the product team level, forcing a constructive

dialog with the development team, a critical determinant of success. That is, QA does not

create quality, but it does measure it.

QA does not prescribe a set of procedures, only that they be created and followed.

The product team, who after all is accountable for the performance of the working trading/

investment system, must be confident that the development team:

● Designed components and evaluated alternative implementations.

● Benchmarked various technologies.

● Properly conducted buy versus build comparisons.
