Study Notes

Problem Solving Skills

Engineers are problem solvers, whether involved in analytical, experimental, computational, or design work
Professional engineering often involves complex, open-ended problems requiring high-level thinking
Problem-solving is defined as obtaining a satisfactory solution to a novel problem, or one not previously encountered
Real-world problems differ substantially from textbook exercises
Many engineering graduates lack essential problem-solving skills needed to tackle true-world problems, even with extensive textbook exercises
Problem-solving involves a structured approach in stages.

Problem Solving Approach: Steps

0. Engage/Motivation: "I can do it! I want to do it!" Define the initial problem statement. Sketch the problem if necessary. Identify given information and constraints. Define the criteria for evaluating the final solution. Determine the real objective of the problem. Examine involved issues leading to the problem. Make reasonable assumptions and do a preliminary guess/estimate of the solution.
1. Define the Problem: Clearly specify the problem's statement, sketching if proper. Identify given information, constraints, and desired outcomes.
2. Explore the Problem: Determine the real objective behind the problem. Analyze all the important issues related to the problem statement. Make reasonable assumptions and preliminary estimates.
3. Plan the Solution: Devise a plan to solve the problem. Map out sub-problems. Utilize appropriate theory or principles. Determine necessary information. Define actions to be taken, including calculations and data analysis.
4. Implement the plan: Execute the planned actions, incorporating calculations and analysis.
5. Check the Solution: Verify the solution's accuracy and reasonableness.
6. Evaluate/Reflect: Analyze the solution's appropriateness against the initial assumptions and estimates. Identify any necessary adjustments/improvements to the solution approach. Assess whether any socially/ethically considerations are relevant to the solution.

Wales's Method - Professional Decision Making Process: Steps

1. Affirmation: Make statements to promote effective psychological management.
2. Define the Situation: Pose questions to gather appropriate clarifying information for a comprehensive interpretation of the situation.
3. State the Goal: Establish a clear, tangible goal that is concrete and detailed enough for everyone to agree when it is reached.
4. Generate Ideas: Generate multiple potential solutions. Analyze each idea and choose the most effective or the combination of ideas.
5. Prepare a Plan: Carefully plan the necessary steps required to transform the selected idea into reality.
6. Take Action: Implement the planned steps.
7. Review and Reflect: Check the overall quality of the solution. Determine what approaches/methods were effective or ineffective for the specific problem solving strategy. Identify necessary improvements and clarification on lessons learned after applying the problem-solving strategy.

Example: Professional Decision Making

A water nozzle problem: Given a piston moving at 5 m/s to force water out of a nozzle, calculate the required force and water efflux speed. Irrotational flow, atmospheric exit pressure, with a diameter D = 6 cm.
