How to change education when 'cutting by intuition' leads to mistakes?

basic information

Proposal for Solutions | Educating Everyone by Showing the "Standard" in Videos to Align Sensibilities Cutting insulation material requires "accurate dimensions," "smooth cuts," and "minimal waste." To achieve this, a shift from "learning by doing" to "understanding by observing standards" in education is essential. ● Compare standard dimensions with cuts that deviate (showing how a ±3mm difference impacts the outcome) ● Demonstrate the correct use of cutters, angles, and pressure through live-action footage ● Reproduce common mistakes (dull blades, cutting at an angle, inability to cut through in one go) and explain the causes and solutions This will enable even newcomers to understand "why we cut at this angle and position" and to replicate it effectively.

Implementation Steps | How to Embed Insulation Cutting Education on Site STEP 1 | Quantify past cutting mistakes, reprocessing, and waste loss to understand the current situation It is particularly effective to organize "who, what task, and what the cause is." STEP 2 | Visualize cutting work standards, procedures, and examples of mistakes using video materials Using tools and materials actually used on site for filming increases credibility. STEP 3 | Establish operations with video + checklist + on-the-job training Combine initial training, regular viewings, and self-study to create a system for repeated education.

Applications/Examples of results

Introduction of Success Case | By switching from "intuition" to "standards," waste material costs were reduced by 60%. At a building materials manufacturer, the cutting process for insulation materials relied heavily on the "craftsman's intuition." As a result, dimensional discrepancies, cutting defects, and excessive waste were common, leading to losses of over 150,000 yen per month. To address this, a video training material summarizing dimensional standards, cutting procedures, and examples of mistakes was introduced and incorporated into the training for new employees. ● The waste rate was reduced by approximately 60% (from 150,000 yen to below 60,000 yen per month) ● New employees became proficient in their tasks two weeks earlier, successfully shortening the training period ● The "intuition" of veteran workers on-site was visualized in the videos, creating a common language for instruction By transforming the process into one that "anyone can do in the same way," stable production and cost reduction were achieved simultaneously.
