Going forward is almost a completely useless phrase. If one says [x] going forward, they mean [x] into the future, but it is very redundant, as one could just as easily say [x]. It seems that many business people want to sound as fancy as possible, so they use as many fancy words as possible to get the same point across. This leads to entire dialogues of contentless speech, filled with words devoid of meaning.
A BBC article puts it much more poetically than me:
When someone says ‘going forward’ it assaults the ears just as, when a colleague starts slurping French onion soup at a neighbouring desk, it assaults the nose.
I think it is a phrase that one should avoid as much as possible, as in the relatively short time it has been in use, it has been abused, hung out to dry, and abused again.
As ianjs has said, it is quite redundant. Redundancy isn’t a bad thing in itself, as it can help to reinforce points. But going forward is so cliché that its effect is lost.
The term can be useful in certain situations, such as “I will be polite to you, going forward”, but it sounds too much like the overused term, that it sounds nicer to say “From now on, I will be polite to you”, or “I am going to start being polite to you.”
Going forward just grates against my ears, and despite it being perfectly relevant in the above example, I would avoid using the term altogether. This is obviously a matter of opinion, but, because of the way the phrase has been used recently, it would be better to use a bit of imagination, and use different wording.
PS: This answer has had 4 up-votes and 3 down-votes, which means it is a very contentious issue. Take this answer with a grain of salt, and remember that English usage is subjective. This probably means that going forward annoys ⁴⁄₇ people who voted on this post, and that ³⁄₇ voters like the term.
It sometimes depends on the context. "The blue" generally refers to, either, the ocean or the sky.
The "wild blue yonder", for example, refers to the sky as it exists as an existential and physical frontier that pushes the limits of human engineering should humans wish to travel to or beyond it.

This is in reference to a 'blue movie', a euphemistic term for a pornographic film.
It has since been toned down somewhat and phrases like a bit of blue can be used to say that something is 'adult' in nature. Often this includes dealing with sexual material but doesn't necessarily mean visually pornographic; a comedian who tells jokes with a sexual theme could be called 'a bit blue'.
going a bit blue then would mean that the programme/character in question is normally 'clean' but has begun to include more adult themes.
It would appear that the term has been used thus since the early 1800s, originating in Scotland, though a clear connection between the colour and the connotation has not been settled on.
N.B.: Bolton comedian Peter Kay is famous in England and well known for his family friendly stand up material. In his shows he will occasionally tell a joke with some sort of subtle sexual reference or other 'adult' theme and then follow the joke by saying 'a bit of blue for the dads there'.
