if you have four years up you should already know most of what you have asked. its like any business outside of the maya 3D app.., you plan, plan and plan again.

you need as many team members as you can get.

you divide the work load amongst those who can perform the tasks the best. OR.., you will have to pick them at random and train them with tuts o r on site.

divide work with constant communication and a good naming convention for files.., make sure every object is names and every scene has a suffix or prefix like '_A' and the date (on EVERY FILE\SCENE)

how do you pipe line a project?? if you dont know you better read a good book about it.., or do a google and u tube search.., you cant expect a one sentence answer to that one?? basically though, allocate and communicate and be enthusiastic even when you dont feel it.

TIME MANAGEMENT and TEAM WORK.., there are a lot of god books and such

try a search for a guy who became famous for giving what known as 'the last lecture,' he gave this ecture at a colledge in the States and died shortly there after.., it is BRILLIANT.., and from there google search his name under time management. he gave another about this not long before he died.

20 min?? aiming high there my friend!! 4 minutes could take three months, 3 days, three years???
