common and repeated use, rules, guidelines or

characteristics for activities or their results, aimed at

the achievement of the optimum degree of order in a

given context


Why we have ong>Standardsong>

Advantages of ong>Standardsong>

• Large market, mass production, lower cost

• World standard products with world standards.

ong>Standardsong> can promote interoperability,I.e.,that two

different implementations can work together,

interoperability leads to more choices.

ong>Standardsong> can contribute more to economic growth

than patents and licenses


Why we have ong>Standardsong>

Disadvantages of ong>Standardsong>

ong>Standardsong> tends to freeze technology for a certain time

period

• Designs may be frozen with too many imperfections

remaining

• Decreased variety results in less customer appeal

• Standardisation costs
