Toyota Way Fieldbook : A Practical Guide for Implementing Toyota's 4Ps

Chapter 16. Consider Alternative Solutions 363

Reflection Activities

1. Present at least two potential solutions for each root cause
   you identified in the previous chapter. Review your propos-
   als with others, and double the possible solutions (to at least
   four) for each root cause. This may challenge your thinking,
   but don’t give up until the list is doubled.


2. Using a matrix to evaluate each solution, rank them based on
   the following criteria:
   a. Is the proposed solution within your control to implement?
   b. Is it simple (preferably a method change)?
   c. Is it possible to implement the proposed solution quickly?
   d. Which of the proposed solutions can be implemented for
   the least cost?


3. Without actual implementation, develop a method to test
   each viable solution that met the above criteria.
   a. Do any of the proposals need to be modified to more
   effectively correct the root cause?
   b. What method will be used to verify the effectiveness of
   each proposal?
   c. Quantify the potential benefit versus the cost for each
   solution.
