MMD™ concept of Information Durability captures the information lifecycle of specific semantic constructs. It is defined as the probability that a third party will be capable of understanding the underlying semantic content as expressed, over time.
One person verbally communicating something to another person is an example of low information durability. As time progresses, the likelihood of the semantic content understood by the second person being exactly what the first person intended is very low. One advantage of using verbal communication is the relatively low cost to transmit the information (and speed). One disadvantage would be the short amount of time that the information survives in its original form to be received.
As a comparison, if one person commits the information to written text, the information is considered highly durable. One advantage is that the information exists as long as the written copy does. One disadvantage is that it is considerably more costly to transmit information that way.
One interesting fact about these two examples is that the receiving time is slightly shorter for written word, however differing skillsets in language may eliminate most of that difference where the receiving party needs to ask clarifying questions concerning the information.
Information Durability is a useful concept that helps clarify change management and process development strategies.
