One of the disadvantages of using standards in specification is that.

Explanation

Using standards in specification is very convenient. They reduce the time and effort to produce. They tend to be very accurate with correct technical terminologies. They are well recognised and accepted by a wide range of suppliers and buyers. However, since a standard is very specific, complex and lengthy, it requires a lot of time to be drafted and approved. Therefore, standard tends to be static and don't encourage innovation. It may also not accommodate latest technology and trends.
