Redundancy investment

Hi,
I have been made redundant after a great number of years. Because of these events, there is a possibility that I may receive an amount of money for my services. I am however, unsure of what the best way to maximise my money would be if I do In fact receive a severance payment... Would it be wiser to invest the money into something (I.e. with a view to seeing some kind of return) or save the money (e.g. in a savings account)?

I understand that there may be lots of variables to take into account which could apply to such a scenario, however any general advice would be greatly appreciated...
