Something that works for me.
Outswinger - An initial step to the line of the ball. Watch it carefully and make a second positive movement as it swings. The aim being to not commit too early and to be in a position to deal with balls you can drive or those that might straighten you up.
Inswinger - I've changed over the years. Use to concentrate on getting outside off stick but I found it difficult to score off as I closed my body up. Now I tend to stay legside of the ball and concentrate on "meeting" the swing with a late forward movement, playing the ball back to where it has come from. ie. if it starts well outside off, I wait for it to shape in and then play it in the direction it came from - normally mid-off/extra cover. If it's straighter than that I try and open myself up as it goes down leg.
There is a massive difference in swing bowling. 90% of bowlers swing it early out of the hand, just watch it go and make your movement when it starts to swing and the line is known. My brother use to swing it late (probably the best outswing bowler I have ever faced, got as far as Bucks U17 before injury did for him) and I lost count of the number of times I would go to flick it off my legs and see my off stick out of the ground. It's so important to not over balance and hold your shape, watch it carefully and play late.
The other thing is practise it. To many people practise looking good on bowling machines instead of practising playing certain types of delivery. Failing that the half taped up tennis/plastic hockey ball was very effective for throw downs.
