Excerpt from the Book
Six steps of problem solving
The six steps of problem solving are as follow:
1. Identify the problem
2. Understand the problem
3. Identify the alternative ways to solve a problem
4. Select the best way to solve a problem from the list of alternative solutions
5. List instructions that enable you to solve the problem using the selected solution.
6. Evaluate the solution
Explanation to each step:
1. Identify the problem:
This is the first step towards solving a given problem. One must properly comprehend what exactly the challenge is.
2. Understand the problem:
One must know and properly understand what is involved in the problem before one goes ahead with the problem. This includes comprehending the knowledge base (which is the pre requisite knowledge that one must have before attempting a particular task) of a problem.
3. Identify the alternative ways to solve a problem:
One must have a set of different approaches towards a problem so that one can choose the best approach from them and can work with some other approach in case the first approach fails. A list of alternatives helps one to prioritize the alternatives.
4. Select the best way to solve the problem from the list of alternative solutions:
One must be totally through with the pros and cons of the problem before going ahead with it. The following are the parameters on which the best alternative is decided:
The solution must be concise and efficient.
It must involve as less manpower as possible.
5. List instructions that enable you to solve the problem using the selected solution:
Instructions, which are listed properly helps one to refer to them for guidance. This increases the efficiency of the task in hand and also saves time, cost, etc.
6. Evaluate the solution:
To evaluate a problem means to check whether the solution of a problem is correct. The solution must be reviewed in proper detail so that the evaluation can be completed efficiently and quickly.
