Problem Solving Process - Presentation Transcript

  1. IST 421 Advanced Enterprise Integration Problem-Solving Processes Sandeep Purao, Ph.D. Associate Professor of IST
  2. The Problem
    • Seeing problems makes me think, but does not tell me how to solve them.
    • Seeing solutions to these problems helps, but it still does not tell me how to solve the problems.
    • What can we do?
  3. An Example
    • Consider this problem :
    • 3X + 2Y = 40
    • 3X + 4Y = 50
    • Here is the solution :
    • X = 10
    • Y = 5
    But how did you get it?
  4. Solution Process
    • Let’s start with the fact that we have two equations:
    • 3X + 2Y = 40 (I) and 3X + 4Y = 50 (II)
    • Let’s subtract equation (I) from equation (II)
    • This will result in a new equation:
    • 0X + 2Y = 10 (III)
    • That tells me that Y = 5
    • Substitute this in either of the original equations
    • 3X + 10 = 40
    • Subtracting 10 from each side yields
    • 3X = 30, which in turn yields X = 10
    Now I get it.
  5. Examining the Process
    • Issues
      • What made you subtract (I) from (II)?
      • Why not the other way around? Or even add?
      • What is the more general lesson for me here?
      • What would happen if I have X, Y and Z?
      • Will I need to have three equations to start?
      • What should be the order? Start with eliminating one?
      • What may happen if we have very many unknowns?
  6. Reflecting on what we learned
    • Problems we will encounter for organizational + technology concerns
      • Are unlikely to have “final” “correct” outcomes
      • Are unlikely to have good yardsticks for assessing the “correctness” of outcomes
      • Will require some creativity in demonstrating the “quality” of outcomes achieved
      • Can, therefore, benefit from examining and reflecting on the “process” of achieving the solutions - as the solution are being developed
  7. Consider this Problem
    • For your project, you need a project management software package.
    • Decide which project management software you will use.
      • Do this with your neighbor.
      • Have one person write steps you are going through.
      • Every so often, read the steps
      • Ask yourselves whether you are doing this in the right manner.
      • Adjust the steps as you answer your own question.
  8. Some Issues
    • Did we consider a large set of alternatives?
      • (Design) Fixation
    • Did we critically examine the alternatives?
      • Familiarity Bias
    • Did we capture the real reasons for choice?
      • Local Rationality
  9. Outcomes
    • You should be able to:
      • Work on problems, and simultaneously, reflect on your problem-solving process
      • Capture your problem-solving process externally so that you can examine it from a distance
      • Share the learning that you gain from this experience with others in the team by verbalizing
