I agree that there is always a right time and a wrong time for introducing something new, and I think it has directly to do with one word: trends.
If we take business data and effectively analyze it to correlate the shopping and spending trends of consumers, we can decide which is the right time to introduce something new to the market.
It would be futile, for example, to break peace with current shopping patterns if the going is good only to introduce something that might divert sales away from a hot item.
What would work best is to exhaust sales in one department and then introduce something new of a different kind when the trends show that people's tastes and needs are shifting.
Timing is an essential element in most endeavors. I would think that bringing out something new in business would be highly dependent on timing, as well. There has to be a need in the marketplace to which the new element introduced can be a response. I think that this takes a level of research of market understanding and the ability to ensure that the timing is right. For example, Apple's introduction of the Ipad last week coincided with an assessment of timing. Certainly, the technology was able to develop the Ipad about two months ago, but it was chosen as last week to be the time to introduce it. Timing was vitally important in this instance, and for the most, part, there is an exact time that figures into the introduction of something new.
It would seem that it is always a right time to introduce new technological "toys" for people, however. Take for example the Ipad introduced by Steve Jobs and Apple Corporation. While jesting was made by other companies that it was simply four Iphones duct-taped together, and flaws were pointed out, people, nevertheless, waited in line from 2:30 a.m. on the morning to purchase one of these devices. As they walked from the store with their new purchase, some held it triumphantly over their heads.
Is it reasonable, then, to conclude that any improvement or "advancement" on technological items that entertain such as the Ipad, televisions, etc. is almost always timely--not to mention "heroic"? (Continuing the facetious tone: Where is a biting satirist like Jonathan Swift when we need him?)
This seems to me like something of a truism -- one of those adages that is surely right but is not really worth much in practical terms.
If you are talking about business, there is clearly a right time and a wrong time to introduce something new. If you have some bright new idea for your product but you introduce it in the middle of a bad recession, it might not do well even if it would do well in more normal times.
The problem is that you never know ahead of time when the right time or the wrong time is going to be. That is why I don't think this saying is very useful.
There is always a right and wrong time to introduce something new. For example: California was experiencing a terrible gas shortage in the late 1970s. The timing was not the correct time to introduce larger vehicles for sale. Had they and they were produced in quantity, the consumers would not purchase them.
Another example has to do with swimming pools during that time. California was experiencing a drought and water restrictions were placed. Companies that had sold swimming pools had to downsize their products instead of up size the pools. Most pools companies ended up closing and it would not have been the appropriate time to introduce new pools, etc..
