Why is it impoprtant to plan your work and be accountable to others?

According to my point if veiw by planing our work we can make it more effective and reliable.if every thing go in proper way than there is a less stress and the person will be satsfied so that to be having accountable for others will be no problem at all .And it is important in a manner that nobody can survive without a society so within a society a person have some duties for which he is responsible and accountable for others.

Hope answer is satisfactory.
