Do you plan before you act? 5

There is one common situations in the life of all of us. At times, we are asked to complete given assignments in a definite time. There are two ways of doing it. One, you immediately start working on the assignment. Two, you plan your every move, determine and arrange needed resources, and also determine what stands in the way of completing the assignment and how are you going to handle these bottlenecks. Once this is done, you put the plan in action.

In first case, you may or may not complete the assignment within given time. In second case, the possibility of successfully completing the assignment increases. Or in other words, you can say that possibility of a possible failure decreases.
