how successfully get open work permit due to spouse?

[scallop]

hello
if spouse has a study visa
how possible to increase chance of getting SOWP ?
what factors decrease chance of obtain visa?
which parameters can increase?
obviously just if we say it's completely based on chance and arbitrary from officer
it won't be correct and accurate because definitely there are so many guys can take it ....but which factor specified ?
and one other Question is which documents needed further than passport,photo,marriage certificates for getting SOWP?

just one things always has been question for me
any one go to Canada one important and most reason is after education proceed to take PR and change it to Citizenship
one reason for giving SOWP is you leave immediately after expiration of visa
but all we know if your spouse going for a study visa she/he can (post graduation work permit) and beside he/she his/her spouse can extend due to starting full-time job under NOC 0,A,B
