ISYS90048 Managing ICT Infrastructure 2 Standards An industry standard refers to a set of specifications to which all elements of products, processes and designs under its realm must conform A standard enables effective coordination of activities between independent developers, carriers, manufacturers or users of technologies A standard enables agreement to be reached on the solutions of recurrent problems Standardization is a process in which conformity is sought and ratified, relating to all relevant elements of products, processes, designs and procedures with the realm of the standard Standards setting seeks to: Protect public health and safety Assure the public of conformance to minimum standards of quality Increase the efficiency of design, manufacturing and use Increase the effectiveness of interoperability Improve economic performance 3 The Standardisation Process Standards may arise through one or more of the following processes: De facto / market driven choice One or more developers propose, design and market products that conform to a given specification Due to the extent of market penetration, the market players may decide which of one or more competing specifications is to be chosen as the de facto standard A de facto standard can often be unstable as the develops enhance or modify its specifications In a risky marketplace, de facto standards can arise through alliances being formed between established players and new entrants; it is less risky to ally with an established product base than to try to go it alone No regulatory or formal standardisation body is involved in the development of the standard 4

ISYS90048 Managing ICT Infrastructure 3 The Standardisation Process Formal standards The specifications of the standard are derived by a recognised standards body For example, the voluntary body International Standards Organisation (ISO) A standards body may have a more or less defined membership For example, the TCP/IP standards have been developed through RFCs (requests for comments) Someone proposes a standard, which is published and a RFC issued Responses enhance the standard until it becomes acceptable Standards bodies have increasingly become more focussed on anticipatory standards of emerging technology Frequently such a body will coordinate the ratification of a de facto standard 5 The Standardisation Process De jure / Regulatory standards
