  1. Problem Demarcation

  2. Why “problem demarcation” ? Best serve your client’s interest 1.  Establish what is your client’s real problem

  3. Why “problem demarcation” ? Best serve your client’s interest 1.  Establish what is your client’s real problem Be efficient 2.  Look only into issues that matter  In adequate detail

  4. Why “problem demarcation” ? Best serve your client’s interest 1.  Establish what is your client’s real problem Be efficient 2.  Look only into issues that matter  In adequate detail Be accountable for your findings 3.  Make clear what you decide to ignore  Reflect on how this limits your conclusions

  5. Why “problem demarcation” ? Best serve your client’s interest 1.  Establish what is your client’s real problem Be efficient 2.  Look only into issues that matter  In adequate detail Be accountable for your findings 3.  Make clear what you decide to ignore  Reflect on how this limits your conclusions

  6. Problem demarcation How to proceed? 1. Starting point 2. Means-ends analysis 3. Several problem statements 4. Objectives trees + System boundaries 5. Compare & Choose

  7. 1. Choose one issue as a starting point
