How This Assessment Was Built, and Where It's Going
Closing the series with a developer's note rather than an ad. Origin, trial-and-error, qualifications and limits, and internal quality-check criteria.
1. Where it began
This tool did not begin on a whiteboard in a large conference room. It was built on one person's desk, as the accumulated result of a long stretch of time.
In college, attending a seminar based on Hyrum Smith's The 10 Natural Laws of Successful Time and Life Management led me to start using a professional planner. As my faith took shape over the following years, I went through countless trials and errors of organizing, searching for, and trying to live out my mission, vision, identity, and strengths. Life Portfolio is the tool that grew out of that accumulated time.
So this assessment did not start as a theory in academia. It is the structured residue of pages written, erased, and rewritten in a personal planner. That is both a strength and a limit. (The limits are covered in Part 4.)
2. What shaped this tool
This tool did not begin in a single book, nor in any one theory. It is the slow residue of many books across self-management, time management, life design, career, psychology, faith, and education; of the lives of many different people watched up close and from a distance; and of the operator's own years of writing, erasing, and rewriting his own life onto paper. One item, one question at a time, that accumulation gradually settled into the shape you now see.
So this tool is less a specialist instrument from any single field, and more a generalist's reference sheet — fragments from several disciplines turned over for a long time on one person's desk, and then organized. That is the character of this tool, and at the same time one of its limits (the limits were already covered in Part 4).
If a few currents within that accumulation had to be named for sitting more firmly with the operator than the rest, they would be: the value-based time-management tradition that shaped the backbone of values → goals → daily action; the paper-tool design philosophy that binds values, roles, and priorities into a single notebook, which shaped the conviction that a life can "fit on one sheet"; and the operator's own faith reference, which kept the question "what does a person live for" from ever being set down. The items themselves were not made religious, but the posture of taking mission, identity, and calling seriously came from there.
That said — we are not the follow-up work of any one scholar, and we are not the heir of any one tradition. We borrowed the shoulders of those who walked the same questions for a moment; we do not borrow their authority to justify this tool. The work of one person, drawn together over a long time across several fields — that is what this is. No more, no less.
3. The person who built it — credentials and limits
The operator, Kim Youngsik, has completed coursework in business administration and holds a Korean Lifelong Education Specialist (평생교육사) license. Not a clinical psychology license. Not a vocational counselor license. Not a doctorate in psychology. That's the accurate statement.
So we draw the boundary clearly. The 1:1 coaching delivered directly by the operator stays inside what business-administration study and a Lifelong Education Specialist license naturally cover — life design, self-understanding, learning & career curation, and self-management coaching. Clinical or medical work, mental-health treatment, and industrial/organizational psychological assessment are out of scope.
A credential tells you, more precisely than what someone can do, what they must not do. Referring out beyond the credential's boundary is an obligation the credential places on us.
That said, "we refuse everything outside our credential" is not our answer either. We plan to extend coaching and after-care coverage step by step through partnerships with experts and organizations across different fields — clinical psychology, vocational counseling, financial planning, career consulting, and faith-based mentoring among them, in a model where we collaborate with credentialed practitioners. We will report progress here on this blog.
4. Four things we hold ourselves accountable to
Four honest questions a maker of an assessment tool ought to keep asking themselves. These are internal standards, not external certifications, and we are working through them step by step over time.
| Standard | Where we are today | Where we are heading |
|---|---|---|
| Content validity Do items cover the domain's core concepts? |
Consistent 11-domain × 4-axis mapping in place. The broader influences that shaped the tool are disclosed in Section 2 above. | Post-hoc weight adjustment as responses accumulate. |
| Face validity Does it feel natural to respondents? |
Several hundred respondents have completed the assessment to date, with no significant complaints about flow or item interpretation. | Regular review by external advisors and coaching partners. |
| Operational quality Data protection, refunds, accessibility, support |
Privacy policy, refund terms, and payment system in operation. Direct support through our Kakao channel. | Broaden accessibility (WCAG) coverage; periodic refresh of terms and refund policy. |
| Psychometric validity Statistical reliability, factor structure (e.g., Cronbach's α) |
Not yet begun. We disclose this stage honestly as "not yet." | Begin in earnest with external experts once response data on the order of hundreds of thousands has accumulated. |
This table is the operator's own set of questions and answers — not an external certification. As stages progress, we will share honestly on this blog again.
5. Closing the 5-part series
Part 1 disclosed all 11 domains, Part 2 the four-axis mapping, Part 3 the weighting system, Part 4 the places we don't reach. Part 5 is the story on the desk where it was built.
This tool may not be right for you. We wrote these five articles so you can decide that accurately. If you conclude it's not right, that's also a good outcome.
A closing line
We live in a time when attempts to organize one's life onto a single sheet of paper grow rarer. May this assessment be a small tool that returns that sheet to your desk. What gets written on it — your hand and your time still decide.
