fast-follow

In the IT world where developers are publishing new software, the occasion may arise where their publication deadline is looming but they are not quite finished the project.  In this case they might decided to do a fast-follow, that is, publish with pretty well all of the product and then follow up very soon with an update to complete the just-published version rather than save it for the next version.  They choose to fast-follow rather than save for the next version.

There is another meaning of fast-follow in the tech world and that is the company strategy to watch on while someone else is innovative in a new market, but, if the product seems successful, to follow up with a rival version of their own.  They need to be quick before the original tech company has secured the market.  The company that is a fast-follower is frowned on by those who feel that there is an element of cheating in this.
