Although there are undoubtedly small systems where the risk may be justified, any reasonably sized system should have a design. The design must be able to exploit the proposed hardware and software platform. A very simple example from the dim and distant past was a system that was based on a TP monitor.

However, they are primarily validation processes. Somebody has to be involved in the key decision-making processes that surround the overall technical solution from a performance perspective. This may be a technical architect or a performance analyst, according to local taste and the capabilities of the individuals concerned, but it is important that it is a suitably knowledgeable person. The danger with a technical architect who has no knowledge of performance is that he may shop around for hardware and software products, concentrating on features and price, but not addressing performance implications.

Marketing people can be extremely economical with the truth, but they tend not to lie, at least not in print.
