George Polya identified step-by-step thought
process for problem solving. They can be applied to reference work,
modeled for reference service users, and taught as enabling
skills.
1. Identify the Problem
 |
Concentrate on its aim. |
 |
What do you want? |
 | Write the question down -- helps focus the mind. |
2. Take Stock of What You Have
 |
What are the facts? |
 |
What inferences can be reasonably and
confidently made? |
 |
What potential uses can be made of the facts
known? |
 |
What assumptions can you use? |
3. Assess the prospects for success
 |
Is there an answer to this question? |
 |
If there is, can you find it? |
 |
Is there just one solution, several solutions, no solution |
 |
Is your idea for solving the problem clear or
vague? |
 |
Is your first hunch likely to work? |
 |
Is there another hunch that may seem less satisfactory, but may lead in the right direction? |
 |
Have initial guesses helped clarify assumptions and strategies as productive or unproductive? |
4. If you can't solve the problem directly, look for
related problems
 |
Look around for an appropriate related problem. |
 |
See what information you can glean from the question |
 |
Find questions from the data. |
 |
See what questions your first examination of information may raise that need clarifying. |
 |
What kind of problem is it? |
 |
Is it related to any known problem? |
 |
Is it like any known problem? |
 |
Do you know a related problem? |
 |
Can you imagine an analogous problem? A more general problem? A more specific problem? |
 |
Make a note of related problems, problems with a similar structure. |
 |
Imagine a similar problem, even a similar problem in a different domain, but preferably one that you could also image a strategy for
solving. |
5. Restate the problem and solve it by
connecting the stated problem to existing knowledge.
 |
This creates a usable piece of knowledge to attack the problem from the outside. |
 |
Restating the problem may bring in new elements. |
 |
Consider the analogy of unwinding a heavily
knotted parcel by locating a free piece of movable string |
 |
The goal is to jog your mind into potential solutions that may
have been overlooked. |
6. Focus on auxiliary problems.
 |
Reduce a difficult problem to several related problems. |
 |
Investigate the validity of any assumptions. |
 |
Widen or narrow the problem by place it in a larger/smaller
context. |
 |
Examine other ideas than the first one that
comes to mind |
 |
Review the logical implications of each idea to
identify those that are helpful |
 |
Use analogies and metaphors to connect knowledge with the problem
at hand.
|
7. When all else fail, reassess the situation
for irrelevant details and side issues.
 |
Examine the problem in its simplest terms, looking again at the question, the known facts, and the circumstances. |
 |
Is everything present being considered? |
 |
Are the concepts that are essential to the
problem understood? |
 |
Is it appropriate to go back and define terms?
Reassessment is the most important problem solving strategy of all!
