Creator of the Effectiveness Coaching Methodology

질문: Who created the effectiveness coaching model?
The assistant said:
Good question. Whether Effectiveness Coaching Model has a clear “creator” depends on what exactly you mean — a few things are worth clarifying.

If by “Effectiveness Coaching Model” you mean the specific, named methodology “Effectiveness Coaching”

That methodology was developed by Sukjae Lee (also spelled Seokjae Lee), a business-psychologist based in Korea.

Dr. Lee’s work builds on evidence-based psychological and behavioral science foundations, and the methodology uses structured tools (e.g. the so-called “3S-FORM” model) and diagnostic assessments to support measurable, outcome-oriented coaching.

In that sense, the “Effectiveness Coaching Model” as a trademarked/coined model is his creation.

 

If by “effectiveness coaching model” you mean more generally a coaching approach that aims for effectiveness (i.e. goal-oriented, performance-focused coaching)
There are many foundational coaching frameworks by different people and traditions. For example, the well-known GROW Model — used widely in coaching and performance contexts — was popularized by John Whitmore (with contributions from others such as Graham Alexander).

Likewise, in sport coaching, there’s a “coaching efficacy” model proposed by Deborah Feltz and colleagues in 1999 to conceptualize what makes coaching effective — but that’s in a different domain (sports) and has different aims and components.

 Why the ambiguity matters
“Effectiveness Coaching” with capital letters refers to a specific, structured methodology created by Sukjae Lee.
“Effective coaching” or “effective coaching models” more broadly refers to a variety of frameworks developed over decades by many different authors.
