It is necessary for us to improve our problem-solving abilities.If you don't properly understand the problem, your solutions may be ineffective or fail entirely.1.For example,is there one problem or actually several?Can you restate the problem in your own words?By spending time with the problem you will better understand it and be equipped to generate（产生）solutions.

2.Collect data,ask people or experts connected to the problem,look for resources online,in print,or elsewhere. Once you have data,organize it.Try to do this by rewording or summarizing it.Perhaps you could even map it out in a chart.You may not need to bother with this step for simple problems,but it will be essential for those of a more complex one.

The first step in finding a solution is to look at data that you have gathered about the problem and to analyze its importance.3.Start with the raw data.Sometimes,information will need to be broken into smaller,more manageable parts or to be ranked for its importance.

4..You might do this on a limited,trial scale at first to test the results.Or,you might go all in.Keep in mind that unpredictable problems which you did not plan can arise at this stage.

Keep in mind that problem-solving works in a cycle.It will generate a number of different solutions that each should not be ignored.5.If not,then you must look for another solution and start the process over again.So make small changes if necessary.

A.If you fix the problem,you have found a suitable solution.

B.Once you have chosen the best solution,put it into practice.

C.You should focus on the problem and your problem-solving process.

D.Gather as many acts as you can about the problem to get a clear picture of it.

E.A hobby is another way that you can continue to improve your problem solving skills.
