Comparative Analysis // Legacy vs. Engine
THE LEGACY.
IS OBSOLETE.
MANUAL INSTRUCTIONAL DESIGN IS A BOTTLENECK. THE ENGINE CONVERTS WEEKS OF WORK INTO SECONDS OF COMPUTATION.
01 // The Authoring Cycle
Traditional Approach
Manual ID Process
Throughput
2-4 Weeks
Subject Matter Expert interviews, manual lesson outlining, repetitive structural authoring.
Mentrast Engine
Mentrast Engine
Throughput
<10 Seconds
One API call. Prerequisite topological ordering and module mapping happen in milliseconds.
02 // Scale & Volume
Traditional Approach
Linear Scaling
Throughput
1-2 courses / month
Scaling requires hiring more instructional designers. Training costs go up as volume increases.
Mentrast Engine
Exponential Scaling
Throughput
Unlimited
Concurrent job processing via BullMQ. 100 courses cost the same human time as one course.
03 // Validation & Quality
Traditional Approach
Subjective Review
Throughput
Inconsistent lesson-to-module ratios. Hallucination risk during manual content scraping.
Mentrast Engine
Algorithmic Validation
Throughput
Planner → Logic Filter → Structural Critic → AI Critic. Algorithmic consistency guaranteed.
