# W8_WAS_Best and Efficient Method of Washing Clothes_mindmapping

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:

1. Alternatives of washing
2. Characteristic of each options

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

1. Laundry per kg,
2. Single tub Top Load Washing Machine and

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.

### One response to “W8_WAS_Best and Efficient Method of Washing Clothes_mindmapping”

1. Again, GREAT case study Pak Wirawan but your treatment of it could have been better. While Mind Mapping is a great tool for brainstorming, why not take it one step further and turn the mind map into a full blown DECISION TREE? (See Engineering Economy, pages 506-514?

See where I am going with this? You are picking really relevant and appropriate case studies, but then you really aren’t using the tools and techniques I am trying to get you to master.

PLUS, if you had used decision trees then not only could you have claimed credit for your Blog but also credit for one of your problems from Chapter 12. REALLY important I get you to spend less time on internet searches and more time in Engineering Economy and Humphrey’s….. Show me you can master those tools and techniques and I assure you, it will help you achieve BOTH of the agreed to objectives of this course…

PASS and ROTI….
