Customer Profile
FASTENER JAMHER TAIWAN INC. (Jamher) is a professional manufacturer in Taiwan’s fastener industry. In the fastener industry, precision is the core key to quality, and precision must be built upon the reliability and trustworthiness of measuring instruments before the data carries any reference value. Jamher’s facility holds numerous measuring instruments, including calipers and micrometers (outside diameter micrometers); ensuring that every single instrument remains in a trustworthy state has long been a major challenge facing its quality assurance unit.
Project Background: The Management Predicament of Instrument Data and Reports Scattered Everywhere
Facing increasingly stringent customer audits and ISO/IATF compliance requirements, the biggest headache Jamher previously encountered when managing instruments was the problem of data “fragmentation”:
- Instrument basic data and manuals were kept in paper form
- Calibration report files were stored in a particular QA staff member’s email inbox
- The Excel spreadsheets for the five MSA studies sat in a folder on yet another computer
When customers came to audit or needed to retrieve the historical records of a particular instrument, it was often like searching for a needle in a haystack, requiring a great deal of time to re-consolidate the relevant data and reports. A slight oversight by staff could lead to a nonconformity being recorded in the audit. According to the requirements of IATF 16949:2016 Clause 7.1.5.2.1, an organization must establish an effective calibration or verification process to ensure the accuracy of monitoring and measuring resources, which was the key driving force behind Jamher’s decision to adopt systematic management.
Why Choose the MiDFUN MSA System
1. Centralized Integration of Instrument Data, Bidding Farewell to Fragmented Management
Through the database architecture of the MiDFUN MSA System, all instrument data entries (including instrument number, brand and model, custodian, accessories, drawing files, as well as all past calibration and loan records) are fully integrated into a single interface. Now, managers only need to enter the instrument number to clearly retrieve all related data of that instrument on a single page, thoroughly solving the problem of scattered data and making handovers and lookups easy and instant.
2. Fully Automated Scheduling and Early Warnings, Never Missing a Single Calibration Again
Instruments require regular maintenance and calibration, but in the era of manual management, relying on Excel or calendars to track the calibration dates of thousands of instruments was not only time-consuming but also frequently led to instruments going past due for calibration because of human oversight, in turn affecting the credibility of product measurements. After the MiDFUN MSA System was deployed, its automated scheduling and notification functions made it the most reliable digital assistant for Jamher’s QA unit:
- Annual Plan at a Glance: The system can automatically generate an annual calibration plan table, using color coding (e.g., red for overdue) to intuitively present the progress status of all instruments
- Proactive Early Warning: Based on the configured calibration cycle, the system automatically sends e-mails to notify the responsible personnel in advance to prepare instruments for calibration; if an overdue calibration occurs, it also sends a notification email in real time
- Zero Audit Nonconformities: Through systematic scheduling management, it ensures all instruments are used within their valid period, directly satisfying the stringent requirements of IATF 16949 and customers regarding instrument calibration cycle management
3. Automated Five-Study Analysis, Breaking Free from Excel Formula Calculations
In the screw industry, beyond basic instrument management, performing MSA five-study analysis (bias, linearity, stability, repeatability, reproducibility) on the measurement system is the key to ensuring trustworthy measurement data. In the past, QA staff had to maintain complicated Excel formulas themselves to calculate GR&R (repeatability and reproducibility) or stability analysis, which not only consumed a great deal of time copying and pasting data but was also prone to misinterpretation due to formula setup errors.
Now, the five-study analysis function of the MiDFUN MSA System has substantially boosted Jamher’s operational efficiency:
- Automatic Calculation and Interpretation: Staff only need to enter measurement data into the system, and the MiDFUN MSA System automatically calculates key parameters such as EV (Equipment Variation), AV (Appraiser Variation), PV (Part Variation), TV (Total Variation), and %GR&R in accordance with the AIAG MSA Manual 4th Edition
- Intuitive Decision Support: The system not only provides the data but also directly delivers a verdict (such as Pass/Fail) and offers various analysis charts. This allows QA staff to immediately judge whether an instrument needs adjustment, maintenance, or repair, without spending time studying statistical results
- Standardized Reports: To meet customer APQP & PPAP requirements, the system can export analysis reports in a standard-compliant format with one click, substantially reducing the time cost of repeatedly creating tables
Deployment Scope and Outcomes
| Deployment Item | Before Deployment | After Deployment |
|---|---|---|
| Instrument Data Management | Scattered across paper, email, and Excel | Centralized management in a single system; retrieve by entering the number |
| Calibration Schedule Tracking | Manual tracking, prone to missing overdue items | Automated scheduling + email early-warning notifications |
| Five-Study Analysis (GR&R) | Excel formula maintenance, error-prone | Automatic system calculation, interpreted per AIAG MSA 4th Edition |
| Audit Response | Needle in a haystack, last-minute data consolidation | Instant retrieval of complete history, responding with ease |
| Report Generation | Repetitive table creation, time-consuming and laborious | One-click export of APQP/PPAP standard-format reports |
Conclusion
With the help of the MiDFUN MSA System, Jamher not only resolved the management anxiety brought on by the sheer number of instruments but also freed its QA team from tedious paperwork to focus on more valuable quality analysis and improvement work. This is not merely an upgrade of management tools, but a successful model of the traditional fastener industry advancing toward digital quality management.

Frequently Asked Questions (FAQ)
Q1: What is an MSA instrument calibration management system? And what is GR&R?
MSA (Measurement Systems Analysis) is a method for evaluating the reliability of a measurement system. The MiDFUN MSA System covers instrument basic data management, calibration cycle scheduling, loan record tracking, and the five MSA studies (bias, linearity, stability, repeatability, reproducibility). GR&R (Gage Repeatability & Reproducibility) is the core analysis of MSA, used to evaluate the proportion of measurement system variation within the total variation. According to the AIAG MSA Manual 4th Edition, %GR&R ≤10% is acceptable, 10-30% is conditionally acceptable, and >30% requires improvement of the measurement system. Simply put, the MSA system is a digital management tool that ensures “the data being measured is trustworthy.”
Q2: How does the MiDFUN MSA System help pass an IATF 16949 audit?
IATF 16949:2016 Clause 7.1.5.1.1 explicitly requires organizations to perform statistical analysis on the measurement systems listed in the control plan. The MiDFUN MSA System provides complete instrument calibration records, automated scheduling management, and five-study analysis reports compliant with AIAG specifications, allowing enterprises to instantly retrieve complete instrument histories and analysis reports during audits, ensuring compliance with regulatory requirements.
