I've recently learned a very effective method of keeping my story plot organized;
Cue-cards!
I write major (or just notable) plot events on cue-cards, and then in another colour pen, i'll write out the details around each specified event~
It's very effective for me, so maybe you should give 'er a try!

I second this.
I don't really outline for writing, but when I start to edit the completed story I outline this way:
I love note cards, (or little slips of papers because I can't afford actual note cards.)
With the note cards you can write down the events on them, and then on the back you can put whatever you want, like Bibbidi suggested.
I like to color code my subplots so I can see how they're mixing together.
And the best thing about note cards/ slips of paper is that you can move them and see all the possible combinations.
My issue with outlining is probably that I just can't do it. I chose the end and flounder about until I get there and then I tighten, sharpen, and expand my plot in editing. I write mysteries, so it can work for any genre.
You've just got to figure out what works for you. My best advice would be to keep it short, and to the point.
In my experience, though I have very little experience with outlining, is that no matter what you're not going to get everything in an outline, no matter how detailed they are they're not fool proof, plot holes may still spring up, new, better ideas pop up that aren't included the ouline, that planned sub plot may actual drag the story down, a new character springs up, a character is forgotten and sometimes the whole outline just goes out the window by page five
I suggest keep your ending, as well as some main events in mind and then start writing.
