Problem solving methods

 To do problem solving, we have to go through the following stages:
    - Recognize that a problem exists 
    - Think about how to solve the problem by investigating and collecting material that will be of help 
    - Try to solve the problem by constructing a plan of attack and putting the plan into action
    - Conclude, after reflection, that the problem has been solved, and make a judgment about how successfully this was done, and what improvements could be made.

    A Methodology for problem solving 
    - step 1 study the problem situation
    - step 2 determine the structure of the required data
    - step 3 determine the information to be output and how the information will be communicated to those who need it.
    - step 4 develop a set of test data and expected results to test the accuracy of processing.
     - step 5 determine the processing required to produce the solution, and represent the solution using suitable technique.
    - step 6 refine and represent the steps involved in producing the output
    - step 7 construct the solution using the selected software
    - step 8 test the functioning of the solution by comparing real output to be the expected output 
    - step 9 refine the solution 
    - step 10 run the solution and produce the desired output and communicate it 
    - step 11 evaluate the efficiency and effectiveness of the solution and refine the solution as required
