v1.7 PCS Sector Intelligence Chapter

Companion to: v1.0 + v1.1 Korean cultural-validity + v1.2 SIOP/AERA psychometric + v1.3 Cross-cultural + v1.4 Trainability + v1.5 AI-graded creative + v1.6 Trainability final. Purpose: Document the sector-intelligence layer and the career-mobility addition, and frame how PCS scores + sector intelligence compose into end-to-end career-fit reasoning. Audience: SIOP / AERA peer-review readers + counselors evaluating PCS career-recommendation outputs. Status: Self-published chapter; not peer-reviewed. Informed by established career-development and labor-market frameworks. Author: Talentopian Research Version: 1.7.0 sector intelligence chapter

1. Why this chapter exists — sector intelligence as PCS validity context

The v1.0 whitepaper §3.4 documented the labor-market overlay (O*NET occupational taxonomy + WEF Future of Jobs industry profiles). Across v1.1–v1.6 the focus was on PCS measurement validity (Korean cultural context, SIOP psychometric standards, cross-cultural generalizability, and trainability). v1.7 closes the gap by documenting the sector-intelligence layer that PCS career recommendations rest on — without which PCS scores would have no interpretive frame at the recommendation level.

The end-to-end career-fit reasoning chain (per the v1.0 whitepaper §1.2 architecture):

PCS scores (48 parameters × 8 categories) → bridge to occupations (O*NET-anchored taxonomy, top-N matched occupations) → enrich with sector intelligence (sector profile + signature skill + salary + AI-resilience + career-mobility paths) → counselor-mediated discussion of fit

v1.7 documents the third step. Without sector intelligence, the second step produces a list of occupation codes without context. With sector intelligence, each recommended occupation carries the descriptive frame a counselor needs for productive discussion.

2. The sector-intelligence layer

Conceptually, the layer is a set of complementary components, each adding one distinct interpretive capability:

Component Capability it adds
Sector PCS benchmark Benchmark a user's PCS profile against the typical profile of a sector
Sector profile A cohesive per-sector descriptor fusing the 8 PCS dimensions with resilience and salary context
Sector signature skill Identifies the dimension that most distinguishes a sector from the cross-sector mean (e.g., creativity in the Arts sector)
Occupation-keyed bridge Re-keys the sector descriptor to individual occupations so dashboards and reports can consume it
Per-user sector context Fuses the relevant sector descriptor into a user's own profile for live use
Salary triangulation Strengthens the salary basis by triangulating across multiple public and licensed wage data sources rather than a single source
Sector opportunity surface Summarizes the most opportunity-rich and most AI-exposed sectors for administrative reporting
Career-mobility paths (NEW in v1.7) For each occupation, surfaces higher-paying careers within the same broad sector

Architecture pattern: the benchmark, profile, and signature components build the sector descriptor; the occupation-keyed bridge makes it consumable per occupation; the per-user context fuses it into individual profiles; salary triangulation strengthens the salary basis; the opportunity surface supports administrative reporting; and the career-mobility component adds the mobility dimension. Each component contributes a distinct capability to the layer.

3. Career-mobility paths — the substantive addition

The career-mobility component surfaces, for each occupation, a small set of higher-paying careers within the same broad (WEF-defined) sector, along with an estimated salary uplift. It is derived from an occupation-to-sector crosswalk combined with the triangulated salary basis.

Illustratively, a lower-paid occupation within a broad sector maps to higher-paid specialities in the same sector (for example, entry occupations in healthcare mapping to higher-paid clinical specialities). Occupations already at their sector's salary peak correctly surface no higher-paying same-sector targets.

3.1 — The honest caveat (preserved)

"CAVEAT: because the grouping is by broad sector, some paths are aspirational rather than realistic transitions; they should be framed as 'higher-earning careers in your field.' A skill-realistic version requires expanded skill-tag coverage across occupations — a future lever."

Interpretation for v1.7: the mobility layer is a "directional aspiration map," not a "realistic career-transition planner." A user whose PCS profile matches a lower-paid occupation, seeing a much higher-paid speciality in their growth-path list, should NOT interpret this as an immediately attainable next step. The counselor frame is: "your sector contains careers at much higher salary points, and here are their requirements — would you want to invest in that path?"

3.2 — Skill-realistic version (future work)

A skill-adjacent version of the mobility layer would filter candidate targets by PCS-dimension distance — showing only careers whose dimensional profile is within a bounded distance of the user's actual PCS. This is future work, dependent on expanded skill-tag coverage across the occupation universe. When that coverage grows, the framing can shift from "aspirational same-sector" to "skill-adjacent same-sector," strengthening the counselor-discussion value.

4. PCS + sector intelligence as end-to-end career-fit reasoning

The composition (per the v1.0 whitepaper §1.2 + v1.7 §1):

   USER GAME PLAYS
        ↓ [per the v1.0 whitepaper §3.3 scoring pipeline]
   PCS SCORES (48 parameters × 8 categories)
        ↓ [per the v1.0 whitepaper §3.4 taxonomy bridge]
   TOP-N MATCHED OCCUPATIONS
        ↓ [per v1.7 §2 sector-intelligence layer]
   ENRICHED OCCUPATION RECOMMENDATIONS:
     - sector descriptor (benchmark + profile + signature)
     - per-user sector context
     - triangulated salary
     - same-sector mobility paths
        ↓ [per the v1.0 whitepaper §1.3 counselor-mediated positioning]
   COUNSELOR-MEDIATED DISCUSSION OF FIT

What this end-to-end reasoning supports (v1.7 substantive claim):

What v1.7 IS NOT:

7. Cross-references

This chapter is designed to be relevant to Korean career-counseling practice, which emphasizes systematic career-information delivery; the sector-intelligence enrichment and mobility paths align with that expectation. We hope to engage the Korean career-counseling community as the framework matures.
