Choosing By Advantages: Sound Decisionmaking
(a two-day event)

This 2-day educational event will provide attendees in-depth training on how to utilize Choosing by Advantages Sound Decisionmaking System (CBA). John Koga is a Certified Value Specialist and Registered Architect, who also has significant experience as a building contractor. In 2018 John retired as VP, Performance and Innovation Resources at The Boldt Company, but is selectively continuing some work in this field.

From your instructor, John Koga:

I believe that “Decisions must be based on the importance of advantages.”

This fundamental rule was discovered in 1981 by a man named Jim Suhr. By working with this rule he developed The Choosing By Advantages Sound Decisionmaking System (CBA). It was extensively tested with others. His book was published in 1999. I met Jim soon after and have become an approved trainer. I also believe that:

• Decisionmakers must learn and skillfully use sound methods.
• Decisions must be anchored to relevant facts.
• Different types of decisions call for different sound methods.
• Money decisions call for special methods and these methods are context-sensitive.

CBA is unified by specific definitions, principles, models and methods. The definitions enable explaining the principles. The models help explain the principles. The methods apply the principles. I am unaware of any decisionmaking system as sound. It encourages the use of correct data in a correct way. It avoids critical mistakes such as distortions and weighing of factors. It helps prevent omissions and double-counting.

Use of Choosing By Advantages will simplify simple decisions by taking fewer steps and simplify complex decisions by taking smaller steps. It will simplify all decisions by correctly using correct data.

An advantage is a difference between two attributes. Seeing the difference from the viewpoint of the alternative that considers it beneficial makes the difference an advantage. Seeing it from the viewpoint of the other alternative makes it a disadvantage. Counting it for both alternatives would be a critical mistake. CBA enables consideration of the importance of all the differences by working with them as advantages.

If you have ever been asked a question similar to either of these, “Which is more important, color or temperature?” or “Is your priority comfort or access?” then you have been asked an unanchored
question that cannot be answered and should not be asked. Factor words such as color, temperature, comfort and access are highly abstract and contain many aspects. As such, they cannot be judged. For example, we must know the context, the criteria and specific attributes. We must move the argument to a level that enables a soundly anchored comparison. A CBA method with its questions and rules will help avoid mistakes and assist in providing a correct and clear decision scenario.

When teaching CBA, I often begin by teaching its very simple methods which are used for most decisions. Then methods for sound consideration of issues such as budget allocation can be learned.

John Koga is experienced in project design and construction management in major markets across North America. He is passionate about improving project solutions, process flow and decisionmaking to increase value delivered. John is an approved instructor of Choosing by Advantages Sound Decisionmaking and introduced its use in Lean Construction. He developed “CBA Training for Project Teams.” John is a registered architect and 1974 graduate of the University of Illinois.
