CAS3 Model -- an approach Not a neat, discrete, sequential order; instead a general framework to systematically solve a problem. If your analysis requires that you go back to a previous step; don’t hesitate to do so.
Commonly practiced in the Army Caused by a lack of discipline
Takes discipline to stick with Provides solution faster in the long run; go slow to go fast
The gap between what is and what is desired (goal/end state) is the condition or situation which must be remedied. In some cases there may be an obstacle which prevents the achievement of a goal. The presence of such an obstacle means a problem exists. Problem Stucture: Problems are classified in terms of their structure, meaning the amount of quantifiable information available to you to solve the problem. Well defined problems have all of the required information available you need to solve them -- example: a math problem 3y+6=18, y=4. Ill defined problems are the opposite and have very little information available to solve them -- What is the prolem in Somalia, Bosnia, etc. Medium defined problems are in between these two extremes and are the kind of problems you will solve here at CAS3 and in your Army career. Application of creative and critical thinking schools using the CAS3 problem solving model will make you a sound decision maker/staff officer.
You may want to use the problem classification exercise here.
Redefine the problem as necessary when new information is acquired and assessed.
Problem statement stated as an infinitive. Ask open ended questions. View the problem from different perspectives. Good point to use the “Blind man and the elephant” exercise.
Post a list of the who, what, when, where, and why of the problem situation. Time invested in defining the problem is never wasted.
You may want to use the classifying facts and assumptions exercise.
You may want to do a screening/evaluation criteria exercise at this point.
I have only $16,000; vehicle must have an automatic transmission; and I will not buy a foreign car. My spouse doesn’t like dark colors and I prefer a four door. The above slide is only used to illustrate application of criteria, not where in the process this fits.
You may use the 26 letters of the alphabet exercise at this point. Ensure that the students recognize that while this exercise demonstrates 12 heads are better than one, it is not really a group problem solving exercise -- hitchhiking of ideas is illustrated. Use group problem solving if: Time is available Acceptance of solution is critical Others have experience or information that you don’t have Use individual problem solving if: Time is not available Problem is well structured Group acceptance isn’t important Leading, caring, training, and maintaining exercise could be used to illustrate group problem solving at this time.
