About This Case

MiDFUN is a Taiwan-based software company focused on manufacturing quality management systems, founded in 1993, with over 30 years of deep experience in the quality management field. This case documents the process in which a domestic electronics manufacturer implemented the MiDFUN SQM supplier quality management system to resolve quality management pain points such as urgent-shipment batch acceptance, MRB concession sign-off, and Data Integrity audit trails.

The MiDFUN SQM system is a supplier quality management system (Supplier Quality Management) used to manage processes such as incoming inspection (IQC), supplier evaluation, MRB concession sign-off, and batch acceptance. The SQM system serves as the ERP’s forward outpost, first sorting out the complex quality management processes and then transferring clean, standard data to the ERP for accounting processing.

Project Background

This is a well-known domestic electronics manufacturer with its headquarters and main production base in Taiwan and overseas plants in Southeast Asia, with end customers spanning multiple top-tier international brands. As order volume grew and product complexity increased, the existing quality management processes began to show structural problems.

The customer approached MiDFUN on its own initiative, prompted by a scenario that recurred every week: a supplier delivers thousands of parts, IQC sampling finds some defects, but the production line is urgently waiting for material. QA can only “inspect and release on the fly” — first releasing several hundred good parts to the line, while the rest wait for the supplier to replace on site and continue inspection.

The problem is that the existing ERP’s standard receiving process is relatively rigid, usually configured as “one document corresponding to a single acceptance result.” To accommodate batch handling on site, staff must manually split documents and re-enter data, which is highly error-prone. The books show everything received into stock, while the actually usable quantity may be less than thirty percent, so inventory accounting carries an error from day one.

The Four Core Problems the Customer Faced

1. Urgent-Shipment Handling Decoupled from Accounting

The ERP itself has a batch-receiving function, but in actual operation, to keep document reconciliation simple, it often struggles to flexibly support the complex on-site scenario of “partial acceptance, partial return, partial hold (concession).” Every time an urgent shipment occurs, QA can only handle it with off-book records, causing the system accounting and the actual inventory to remain inconsistent over the long term.

2. Concession Decisions Lack a Formal Record

When production pressure outweighs the insistence on quality, MRB concession release (Concession) is often coordinated by phone or e-mail, with no formal sign-off process. Once a subsequent customer complaint arises, the decision process that lacks a complete record makes the QA department the sole party held accountable.

The QA manager said bluntly in an interview: “Purchasing and production control both said to release it, but when something goes wrong, I am the only one who has to carry it. We hope to use the system to turn risk decisions into shared responsibility.”

3. Difficulty Locating Batches in the Receiving Area

Although the plant had implemented a WMS, its management of the temporary storage locations in the “receiving area” was relatively coarse. When a specific batch needed re-inspection, the WMS could only provide an approximate area and could not precisely locate the specific pallet. QA staff had to unpack and check every item across the entire area one by one, which the floor described as “needle-in-a-haystack material searching.”

4. Data Trust Crisis at the Overseas Plant

The overseas plant had once been flagged in a customer audit for insufficient Data Integrity. The practice at the time was paper-and-pencil recording followed by scanning and archiving, and both the authenticity and traceability of the data were questioned. The auditors explicitly required: “The data must be tamper-resistant and retain a complete modification trail.”

How the MiDFUN SQM System Solved It

The root of these problems is not “the system is hard to use,” but that the existing system architecture (ERP / WMS) focuses on finance and logistics and cannot delicately support the special processes of quality management.

The MiDFUN SQM system’s entry point is not “providing a better piece of software,” but “acting as the ERP’s forward outpost, first sorting out the complex processes and then transferring clean, standard data.”

Cut One: Implementing Batch Acceptance with a “Middle-Layer Buffer” Logic

The ERP dislikes complex document splitting? Then the MiDFUN SQM system handles it first, before the ERP.

The MiDFUN SQM system designed an independent “batch disposition table,” allowing the same receiving document to be split into multiple segments for handling:

• Batch one: passed, the system automatically transfers a receiving document to the ERP
• Batch two: failed, locked in stock, awaiting supplier replacement
• Batch three: under inspection

The system uses “status flags” to control the flow — the ERP always receives clean, closed documents, while the complex on-site disposition status is fully recorded by the MiDFUN SQM system.

Benefit: the production line’s urgent-shipment needs and accounting accuracy can coexist, and QA no longer has to sacrifice process flexibility to accommodate the system.

Cut Two: Making “MRB Concession Release” Combine Flexibility and Accountability

The MiDFUN SQM system moves the MRB (Material Review Board) process online, and, taking the reality of urgent shipments into account, designed a dual-track mechanism of “standard sign-off” and “emergency release”:

Standard process:

1. IQC judges a batch as failed -> the MiDFUN SQM system automatically issues an MRB document
2. The MRB document is transferred to the sign-off system, carrying the part number, quantity, and defect reason
3. Purchasing, SQE, PM, and production control sign off online in sequence
4. After sign-off, the system records the complete decision trail and executes the chargeback or return

Emergency release (Conditional Release):

When the production line truly cannot wait, an authorized manager can first perform a “conditional release.” The MiDFUN SQM system will forcibly flag that lot number as a risk and require the sign-off procedure to be completed within a set deadline.

Benefit: quality risk shifts from “QA carrying it alone” to “the relevant units deciding together.” Even an emergency release leaves a trace — whatever passes through leaves a mark.

Cut Three: Establishing a Data Connection with an Audit Trail

To address the overseas plant’s Data Integrity trust crisis, MiDFUN introduced Bluetooth wireless-transmission gauges connected directly to the SQM system. After inspection staff take a measurement, the data is transmitted directly into the system database.

The point is not “absolutely no modification” — because staff can indeed make operating mistakes. The point is the “audit trail”:

• Raw data is uploaded directly, avoiding transcription and key-in errors
• If modification is needed, the MiDFUN SQM system forcibly requires the reason for modification to be entered and records the modifier ID and timestamp

Benefit: it fully meets top-tier brand customers’ Data Integrity audit requirements. The data stands up to scrutiny, with no fear of an audit digging in.

Cut Four: Making the System Support the Local Language

The key threshold for driving digitalization at an overseas plant is “people.” If frontline operators cannot understand the interface, even the most powerful system features amount to nothing.

The MiDFUN SQM system developed a deeply integrated multilingual interface, covering all menus, field names, and system prompt messages, ensuring operators can truly get the hang of operating it.

Benefit: the overseas plant finally has the conditions to move from “paper scanning” to “digital native.”

Bonus Cut: A Cross-Plant Quality Firewall

The documents of the Taiwan plant and the overseas plant are managed separately, with isolated permissions and independent operation. But the materials are supplied by the same batch of suppliers, and the problems are often the same problem.

The MiDFUN SQM system established a “Quality Alert” mechanism in the material master data:

• Plant A finds an anomaly in a certain part -> opens an alert in the MiDFUN SQM system
• Plant B scans the same part number for inspection -> the system actively pops up the alert and forces the inspector to confirm

Benefit: lessons learned are no longer reports gathering dust, but a dynamic line of defense embedded in every document. The mine Plant A stepped on, Plant B will not step on again.

Reference Results: Peer Companies’ Real Results After Implementing the MiDFUN SQM System

This project is currently in the implementation stage and has not yet produced closing data. The following are the actual results other peer customers achieved after implementing the MiDFUN SQM system, provided for reference:

Industry	Improvement Item	Before Implementation	After Implementation
Electronics EMS (500+ employees)	Daily report preparation time	2 hours	5 minutes
Electronics manufacturing (automotive supply chain)	IQC paperwork volume	Baseline	Reduced by 80%
Technology manufacturing (annual revenue NT$5 billion+)	IQC staffing	20 people	5 people (combined with a skip-inspection mechanism)

* IQC staffing optimization mainly comes from the combined effect of implementing the MiDFUN SQM system’s skip-inspection mechanism (Skip-lot) and automating paperwork.

This customer’s goal is to systematically manage the incoming inspection process for tens of thousands of items each month and to pass the end customers’ supply chain audit requirements.

Why the Customer Chose MiDFUN

During the project evaluation stage, the customer invited multiple system vendors for comparison at the same time.

The customer ultimately chose to work with MiDFUN, with the feedback: “Other vendors sent more people to the meetings, but their responses on detailed questions were not clear enough. MiDFUN’s modules were more complete, and its grasp of practical issues was also more on point.”

---

Conclusion

This project once again confirmed one thing for MiDFUN: the success or failure of digital transformation lies not in the number of system features, but in whether it can solve the most practical pain points on the front line.

The MiDFUN SQM system’s “batch acceptance” gives urgent-shipment handling proper system support, no longer relying on off-book records to muddle through. Its “MRB dual-track sign-off” gives concession decisions both flexibility and accountability. Its “audit trail” lets inspection data stand up to the strictest customer audits. Its “multilingual interface” finally lets the overseas plant’s digitalization truly take root.

When the system can support the process, and the process can implement management, a digital tool can truly become part of an enterprise’s competitiveness.
