Learning Agility via Time-to-Skill (TTS) predicts future A-Level candidates

2

Three-Layer Measurement Framework

Multi-dimensional validation ensures training translates to effective work performance

Layer 1: Input & Efficiency

LXP Activity & Learning Velocity

Measures training investment, engagement patterns, and speed of skill acquisition. Time-to-Skill (TTS) serves as operational proxy for Learning Agility.

Core Predictive Metrics

Pre-calculated, indexed metrics enabling rapid managerial intelligence and talent insights

📊
Skill Match Score (SMS)
78%
Weighted average of current validated competency levels vs. A-Level target profile
📉
Gap Magnitude Index (GMI)
2.3
Numerical difference between employee's skill level and target A-Level requirement
Time-to-Skill (TTS)
14d
Speed of skill acquisition - operational proxy for Learning Agility and high-potential identification
🎯
Content Efficacy Score
4.2/5
Retention rate weighted by assessment pass rate - measures training ROI without recalculating millions of events

🏗️ Architectural Benefit: 47x Performance Improvement

By pre-calculating and indexing these metrics, complex managerial queries execute in <200ms instead of 8,500ms. This transforms the system from a slow reporting tool into a real-time talent intelligence platform.

Data Gap Solutions

Specific tracking mechanisms and database schemas to close critical intelligence gaps

Gap 1 Solution: Behavioral Learning Efficiency

Track In-Platform Learning Behaviors

Problem: We know when users complete content but not HOW efficiently they learned. Can't distinguish between a user who mastered content in 2 focused hours vs. 2 hours spread over 20 sessions with constant help access.

✅ Recommended Tracking

New Table: lxp_user_learning_behaviors
Schema:
• user_id (FK)
• course_id / lesson_id (FK)
• session_start / session_end (timestamps)
• help_docs_accessed (int) - count of help article clicks
• video_replays (int) - times rewound/replayed
• pause_duration_seconds (int) - total pause time
• attempt_failures (int) - practice attempts before success
• navigation_efficiency_score (float) - clicks to completion ratio
• focus_time_percentage (float) - active vs idle time
• confusion_indicators (json) - rapid back/forward navigation
• created_at
Analytics to Calculate:
  • Learning Efficiency Index (LEI) = (content_duration / actual_time_spent) × (1 - help_access_frequency)
  • Mastery Velocity = skills_acquired / (total_time - pause_time)
  • Self-Sufficiency Score = successful_attempts / total_attempts
  • Correlation with TTS = Compare LEI scores with Time-to-Skill for predictive modeling
Implementation Notes:
  • Track via frontend JavaScript event listeners (page visibility API, click tracking)
  • Batch events every 30 seconds to reduce database load
  • Privacy consideration: Aggregate at session level, don't track every click
  • Use for Learning Agility scoring: High LEI + Low TTS = High Potential candidate
Gap 2 Solution: CAD Model Quality Analysis

Automated Parametric Assessment Engine

Problem: Current assessments only validate visual correctness (Level 2). Cannot measure model robustness, feature efficiency, or constraint architecture quality (Level 4-5 skills).

✅ Recommended Tracking

New Table: cad_model_quality_assessments
Schema:
• assessment_attempt_id (FK to skills_analyzer_test_attempts)
• model_file_path (string) - S3 or local path
• feature_count (int) - total features used
• feature_efficiency_score (float 0-100) - vs benchmark
• constraint_quality_score (float 0-100)
• constraint_fully_defined_percent (float)
• robustness_test_pass_count (int) - successful dimension changes
• robustness_test_total_count (int) - total variations tested
• design_history_clarity_score (float 0-100)
• feature_naming_quality_score (float 0-100)
• rebuild_errors (int) - errors during automated rebuild
• geometric_accuracy_deviation (float) - mm from spec
• overall_quality_grade (enum: A, B, C, D, F)
• analysis_timestamp (timestamp)
• analyzer_version (string)
Analysis Engine Components:
🔍 Feature Efficiency Analyzer

Compare student's feature count and approach vs. expert baseline model.
Flag: redundant features, inefficient patterns, over-complexity

🔧 Robustness Tester

Programmatically modify 20+ key dimensions via API.
Test: model rebuild success, constraint preservation, feature stability

📐 Constraint Validator

Parse constraint structure from model file.
Check: fully-defined sketches, proper relations, geometric intent

📝 Design History Auditor

Analyze feature tree organization and naming.
Score: logical grouping, descriptive names, folder structure

Implementation Strategy:
  • SolidWorks API Integration: Use SOLIDWORKS VBA/C# API to programmatically open, analyze, and test models
  • Queued Processing: Run analysis as background job (can take 2-5 minutes per model)
  • Scoring Algorithm: Weight criteria: Robustness (30%), Feature Efficiency (25%), Constraints (25%), Design History (20%)
  • Proficiency Mapping: 90-100 = Level 5, 80-89 = Level 4, 70-79 = Level 3, 60-69 = Level 2, <60 = Level 1
  • Expert Baseline Library: Maintain reference models for each assessment task scored by master engineers
💡 Quick Win Alternative (Phase 1):

Before building full automation, start with manual expert review scoring:
• Add expert_review_scores table with same fields
• Expert instructors score 3-5 assessments per student manually
• Collect 6 months of data to train ML model for automation
• Validates scoring rubric before investing in automation

Gap 3 Solution: Structured Performance Data

Competency-Based Manager Reviews

Problem: Performance reviews are qualitative narratives stored in external HRIS. Cannot quantify behavioral competencies or map to framework proficiency levels for skill gap analysis.

• created_at
Manager Review Interface Design:
📋 Guided Review Form Structure
Section 1: Technical Competencies (from framework)

For each competency (Parametric Modeling, Assembly Design, etc.):
• Show competency definition & level descriptions
• Radio buttons for Level 1-5 selection
Compared to LXP Score: Show employee's assessment level alongside for validation
• Optional text field: "Provide specific work example"
• Trend indicator: Improving / Stable / Declining vs last review

Section 2: Behavioral Competencies

Same structure for: Communication, Teamwork, Problem-Solving, Adaptability, Design Excellence
• Level-specific behavioral indicators shown for each level
• Example prompts: "How does employee communicate complex technical concepts?"
• Peer feedback summary displayed (if 360 enabled)

Section 3: Job Performance Metrics (Quantitative)

Manager enters objective metrics:
• Projects completed on time: ___% (Benchmark: 87%)
• Design defects requiring rework: ___ count (Benchmark: <3)
• Peer review average score: ___/5.0
• Knowledge sharing: ___ mentoring hours / training sessions led

Data Validation & Quality Controls:
  • Calibration Meetings: Managers review sample scores together to ensure consistency
  • LXP Comparison Alert: Flag when manager rating differs >2 levels from assessment score
  • Required Evidence: Level 4-5 ratings require specific work examples
  • Trend Analysis: System flags unusual rating changes (e.g., Level 5 → Level 2 without explanation)
  • Completion Enforcement: Dashboard shows % of team reviewed; blocks cycle close until 100%
Integration with Framework:
  • SMS Calculation: Manager scores weighted 40%, LXP scores 40%, Job metrics 20%
  • GMI Update: Recalculated immediately after review submission
  • A-Level Validation: Manager ratings validate or challenge LXP-predicted A-Level candidates
  • Feedback Loop: If manager consistently rates lower than LXP, trigger assessment difficulty review
  • Development Plan Generation: Auto-suggest training based on lowest-scored competencies
📊 Sample Analytics Enabled:
Manager Calibration Report: Compare rating distributions across managers
LXP-to-Performance Correlation: Validate assessment accuracy vs. job performance
Behavioral Competency Heat Map: Org-wide view of soft skill strengths/gaps
Promotion Readiness Score: Combine manager ratings + LXP + metrics for succession planning
Development ROI: Track competency improvement post-training investment
