Its really simple as you have to check out the folowing:

(1) who(who made this issue),what(what was the actual cause of the issue?),when(when did this issue occur?),where ( where did this happen),why(why did this happen),how( how did this happen)?

and last but not the least you have to use your brain and common sense.

Take for and Example Like:

If an issue comes up saying that people are not doing their work properly in an office and in the end of the month the outcome of performance is not upto the expectations of the standards of the company. then we must look out for the following like helding up Meetings and pointing out people whose standards are not upto the mark and try to help in motivating them, and try to improve their faults, in making efforts to improve their performance standards and and then if things are not going as expected then actions should be taken against them which in Rare cases may result in Termination/suspension/or demotion of the specific employee. this is how most of the issues can be resolved....
