Step 1- Problem or Opportunity Statement
Right now I’m living with my wife. We’re considering the best and efficient method of washing dirty clothes. Before doing any calculation, I will use mind mapping to capture the big picture of clothes washing options.
A mind map is a graphical way to represent ideas and concepts. It is a visual thinking tool that helps structuring information, helping you to better analyze, comprehend, synthesize, recall and generate new ideas.
Step 2 – “FEASIBLE alternatives”
There are a few alternatives in doing laundry, listed above
Step 3- Develop the outcomes for each alternative (minimum 2)
These are my mind mapping of possible washing options.
Step 4- Selection of the acceptable criteria
In the mind map, captured:
- Alternatives of washing
- Characteristic of each options
- Advantages & disadvantages
Step 5- Analysis/ Comparison of the Alternatives against the Criteria
Mind mapping is used to get a big picture of each alternative. No decision is made, because the choice is still not mathematically calculated. But at the mind map, I can see some choices are too time consuming (washing by myself and 2 tube top load washing machine) and laundry per piece will be too expensive.
Step 6- Selection of the Best/ Preferred Alternative Compared against the Criteria
My wife and I simplify the choices to
- Laundry per kg,
- Single tub Top Load Washing Machine and
- Front Load Washing Machine
as they are less time consuming and affordable for a long term
Step 7- Performance Monitoring and Post Evaluation of Result/ Follow up Assessment
For more comprehensive comparison, I will use life cycle calculation or Multi Attribute Decision Making. Therefore I can eliminate the choices to a solution of washing method I will use. Please stay tuned for my next blog post.
