SYSTEM / 004 — CASE STUDY
Trifecta Performance Lab
LOCAL-FIRST APPLICATION / v2.2.0
A bilingual trainer-development and performance system connecting learning domains, assessment, evidence, progression and human-performance design.
01 / CONTEXT
Context
Trainer development connects learning objectives, station design, observed performance, assessment and progression. The system is Arabic-first and bilingual.
02 / PROBLEM
Problem
A total score can obscure missing evidence or a critical safety failure. Progression requires inspectable evidence and explicit gate decisions rather than compensating aggregate scores.
03 / DESIGN PRINCIPLE
Design Principle
Keep the build-versus-diagnose distinction explicit. Link evidence to progression and treat Critical Safety Failure as a non-compensable No-Go.
04 / SYSTEM
System
A local-first trainer-development application covering Cognitive, Psychomotor and Affective learning domains, plus Physical, Technical and Cognitive / Neurophysiological performance dimensions.
05 / WORKFLOW
Workflow
- Curriculum
- Levels
- Stations
- Drills
- Evidence Chain
- Gate decision
- AAR & intervention
06 / CURRENT STATE
Current State
- Curriculum → Levels → Stations → Drills hierarchy with evidence-based progression.
- Gate decisions: Go, No-Go, Need More Data and Retest. Critical Safety Failure is non-compensable.
- Evidence Chain, 15 guided cases, calibration tools, performance profile, AAR and intervention tools.
- Arabic RTL and English LTR, keyboard navigation and responsive layouts.
- Device-local storage, browser print/PDF, JSON station export and offline core content.
