Documentation Checklist

This checklist is prepared to ensure proper transfer of all product information, instructions, and records to user, service, and production teams. The goal is to implement principles of information integrity, traceability, and easy field access.

End User Documentation​

1. Are user documents prepared and made accessible on appropriate platforms?​

Each product should have an information package for users:

• Package contents: user manual, warranty document, technical support information, safety warnings
• Presentation format:
  • Physical: printed manual or Quick Start Guide
  • Digital: access via QR code, NFC tag, or web portal link
• Document version should match product revision (e.g., User Manual v1.3 – HW Rev. B)

2. Are usage instructions prepared clearly, with visuals, and in understandable format?​

Manuals should be prepared according to understandable language and visual communication principles without compromising technical accuracy:

• Critical steps (e.g., connection, calibration, charging, software update) should be supported with icons or diagrams
• Instructions should be in short sentences, in step-by-step structure
• Simplified terminology should be used according to user level (e.g., "charger" instead of "adapter")
• Safety warnings should be classified with "⚠️ Caution", "❗ Warning", "⛔ Danger" symbols

3. Are warranty and service procedures explained in detail?​

Warranty condition limits and service processes should be clearly communicated to users:

• Warranty period (e.g., 24 months) and valid regions should be specified
• Out-of-warranty situations (e.g., unauthorized intervention, liquid contact, physical damage) should be clearly listed
• Service process:
  • Registration with product serial number
  • RMA (Return Merchandise Authorization) steps
  • Shipping and delivery instructions
• This information should be integrated with after-sales support portal or service centers

4. Is a user troubleshooting guide available?​

Common user errors and their solutions should appear in the manual in simple format.

• Structure: table format or "problem → cause → solution" scheme
• Examples:
  • "Device won't turn on → Check power adapter"
  • "No data connection → Check Wi-Fi signal or cable"
• Unnecessary technical terms should be avoided, supported with visuals
• Critical situations should include information directing users to technical support team

A well-prepared Troubleshooting Guide can reduce service load by up to 30% and increase customer satisfaction.

Service Documentation​

5. Has a service specification been created?​

A Service Specification should be prepared for each product and presented to technical personnel. Content:

• Fault classification: Critical, medium, low priority
• Problem-solving steps: Measurement sequence, test procedure, parameter limits
• Test equipment list: Multimeter, oscilloscope, function generator, software tool
• Error code explanations: LED blink pattern, screen warnings, log file references

Service specification should be kept current according to product software and hardware revisions.

6. Are parts and module lists (Service Part List) defined?​

For each component replaceable during service, part number, description, and replacement procedure should be defined. List structure:

• Part Code (Part No.)
• Description
• Quantity (Qty)
• Usage Area / Module (Assembly Reference)
• Replacement Procedure Reference
• Stock Status (Available / Discontinued)

Module-based repair strategies ("Field Replaceable Unit – FRU") should be clearly marked. List should be integrated into ERP system so service personnel can directly request parts.

7. Are troubleshooting and module replacement instructions ready?​

Detailed troubleshooting and module replacement procedures for service personnel should be prepared.

• Structure: "Step-by-step" explanation + visual support (photo, drawing, schematic)
• Required tool list for each operation (e.g., torque wrench, ESD wristband, soldering station) should be specified
• Safety warnings:
  • "⚠️ De-energize the device before working on this module"
  • "⚡ High voltage risk – only authorized technician should intervene"
• In failure analysis, measurement values, acceptance limits, and typical failure symptoms (e.g., voltage deviation, overheating) should be listed

8. Has service documentation been uploaded to a secure access platform?​

All service documents should be shared digitally accessible only to authorized personnel.

Access methods:

• Service portal (web-based) → login, role-based authorization
• Intranet or ERP integration → PDF or HTML document viewing
• Mobile access (tablet/smart device) → quick viewing in field maintenance

File format: PDF (revision protected) or web-based module (HTML/Markdown). Access security: two-factor authentication, access logging, document signing. Each document's revision history should be recorded (e.g., Service Guide v2.1 – Updated 2025-11-12).

Manufacturing (Production) Documentation​

9. Has a manufacturing specification been created?​

All technical parameters of the production process should be defined in sequential and verifiable format. Manufacturing Specification should include:

• Assembly sequence: Module, sub-assembly, and component basis
• Solder temperature profile: pre-heat, peak temperature, cooling curve (e.g., 245 °C ±5 °C)
• Screw tightening torques: e.g., M3 screw → 0.4 Nm, M4 → 1.0 Nm
• Test steps: duration, parameters, pass/fail limits
• Equipment list to be used: station-based (e.g., AOI, ICT, Reflow, Wave)
• ESD and clean room conditions: humidity/temperature limits (below 70% RH, 20–25 °C)

Document should be kept as "Controlled Copy" on production line, digital version managed via QMS.

10. Are equipment and connection details to be used defined?​

All tools, molds, and test hardware to be used on production line should be determined and verified. List format:

• Equipment Name (e.g., Weller WX2 Soldering Station)
• Model / Serial No.
• Purpose of Use
• Calibration Date / Label
• Connection Details (e.g., test fixture pin order, cable set code, socket type)

Assembly fixtures, cable harnesses, and test jigs should be added to production documents with visual reference. "Preventive Maintenance" plan should be separately defined for critical equipment.

11. Are production parameters tracked with current version number?​

All production documents should be under revision control. Each document:

• Should include revision code (A/B/C etc.), date, preparer and approver information
• Revision history (change log) descriptions: "Solder profile updated – Rev. B (2025-09-18)"
• Only "latest revision" should be activated on production line via QMS/ERP system
• Old revisions should be archived as "Obsolete", out-of-use copies removed

12. Are production documents accessible only to relevant production unit?​

Production document access should be controlled for information security and authority management. Access restriction:

• Operator level: access only to own station documents
• Production engineer: authority to edit production parameters
• Quality control: view test reports

File sharing: via intranet, document management system (DMS), or secure ERP module. Security measures: encrypted access, digital signature, access log records. Confidentiality classification: "Public / Internal / Confidential".

Module Manufacturing Specification (Sub-Assembly Documentation)​

13. Has module manufacturing specification been prepared?​

All manufacturing rules to be applied in sub-system or module production (e.g., sensor PCB, communication board, power unit) should be written down. Sub-Assembly Manufacturing Specification should include:

• Module function definition and target test parameters
• Production stages (soldering, assembly, testing, cleaning, packaging)
• Quality control steps (AOI, ICT, FCT, visual inspection)
• Required equipment and process environment conditions (e.g., ISO Class 8 clean room, ESD area)
• Approved component list (AML – Approved Manufacturer List)

This specification standardizes module manufacturer performance and ensures full compatibility with final product.

14. Are materials and parameters to be used in electronic production defined?​

All production materials, process chemicals, and parameters should be documented. Material type and properties:

• Solder alloy: SnAgCu (SAC305) – RoHS compliant
• Flux type: no-clean, halogen-free
• PCB surface finish: ENIG or HASL
• Reflow profile: 3 °C/s ramp, 245 °C peak, 60–90 s soak
• Test jig type: ICT + boundary scan

Each parameter should be compatible with manufacturer recommendation and stored in Process Sheet.

This practice increases production repeatability and minimizes faulty solder rate in the field.

15. Are qualification documents and quality certificates to be requested from suppliers defined?​

Component reliability to be used in production should be supported by supplier documents. Requested documents:

• ISO 9001 / IATF 16949 quality management certificate
• IPC-A-610 Class 2 or Class 3 production qualification
• RoHS / REACH / Conflict Minerals declarations
• UL E-File or flammability test (UL94 V-0) certificates
• Calibration reports (for measurement equipment)

All documents should be stored in supplier qualification file and updated annually. This practice is mandatory for Supplier Reliability Assurance.

16. Are manufacturer qualification conditions (Vendor Qualification) defined?​

Subcontractor firms should be approved according to production quality and past performance. Evaluation criteria:

• Delivery performance (OTD above 95%)
• Defect rate (target below 1000 PPM)
• Certificate validity (ISO 9001, RoHS)
• Test infrastructure and equipment calibration status
• Product return rate (below 0.5% RMA)

Audit method: Supplier Audit Form (SAF) or Process Capability Audit (Cp/Cpk). Corrective action plan (Supplier CAPA) should be prepared for non-compliant suppliers.

17. Are all production and test documents backed up on appropriate digital platform?​

Production records, test reports, and quality documents should be regularly protected digitally. Backup infrastructure:

• Daily automatic backup (NAS or cloud-based system)
• Copies at least 2 different physical locations (off-site backup)
• Data integrity: file signing (hash/checksum) and access logging should be applied
• File format: PDF/A, CSV, XML, or database integrated to ERP
• Backup policy: "3-2-1 Rule" (3 copies, 2 different media, 1 off-site)

General Documentation Management​

18. Are all documents managed with version control system (e.g., Git, SVN, PLM)?​

Current versions of documents should be tracked via version control systems. Platforms that can be used: Git, SVN, PDM/PLM (e.g., SolidWorks PDM, Altium Concord, Fusion Manage). The following information should be automatically stored in each file:

• Revision code (A/B/C or v1.0/v1.1)
• Change description (change log)
• Responsible person / approver
• Date and version number

Separate "repository" structure should be used for code, schematics, documents, and production data.

19. Are document formats standardized (PDF, DOCX, XLSX, STEP, Gerber, etc.)?​

All project files should be in common and long-term accessible formats. Recommended standard formats:

• Text documents → DOCX or PDF/A
• Drawings / CAD → STEP, DXF, DWG
• PCB → Gerber X2, ODB++, IPC-2581
• Spreadsheets → XLSX, CSV
• Images → PNG, SVG

All documents should be archived as "read-only master" copy, revisions kept in separate folders.

20. Is document access classified by user types?​

Access management should be configured as role-based (RBAC). User roles:

• Design / R&D: Full access to all technical data
• Production: View only approved production instructions
• Service: Only maintenance manuals and test procedures
• Customer / Auditor: Limited access, read-only PDF

Access control should be integrated into LDAP/Active Directory or ERP system. Each access event should be logged, stored for 12 months.

21. Is the security of archived documents (encryption or backup) ensured?​

Backup and security measures should be implemented against data loss, corruption, or unauthorized access. Backup policy:

• Daily automatic backup
• 3-2-1 rule (3 copies, 2 different media, 1 off-site)
• Encryption: with AES-256 or equivalent algorithms
• Data integrity verification: SHA-256 hash records
• Disaster Recovery Plan: recoverability tests from backups within 24 hours

22. Is document update process defined throughout product lifecycle?​

Automatic document revision should be ensured after product revision, software update, or production changes. Change flow:

1. Request (Change Request)
2. Evaluation (Impact Analysis)
3. Approval (Engineering / QA)
4. Release

Entire process should be conducted via "ECO – Engineering Change Order" or "PCN – Product Change Notification". Revisions should be synchronized to both technical and user documentation.

23. Is document change notification (PCN / ECO form) template defined?​

A standard Change Control Form should be used for each change. Form content:

• Reason for change (e.g., supplier change, bug fix, improvement)
• Affected files / products
• Implementation date and valid revision
• Approving engineer and quality officer

PCN (Product Change Notification) should be used for notification to customers or suppliers. ECO (Engineering Change Order) is for internal engineering and production coordination.

24. Do all documents have QR code or digital reference link?​

Each printed or PDF document should contain digital identity (QR / URL) providing access to the latest version.

• QR code should be linked with document number and version (e.g., DOC-PSU-REV-C)
• When scanned, redirects to current version of document (e.g., docs.company.com/rev/DOC-PSU-C)
• This method prevents use of old documents in the field

This item is one of the fundamental steps of "Digital Thread / Traceability" approach.

25. Are multilingual user and service documents current?​

If the product is sold in different regions, all documents should go through localization processes.

• Languages: English (base), Turkish, German, French, Spanish, etc.
• Technical terms should not be corrupted by translation; standard dictionary should be used
• Version in each language should be synchronized with main document revision

26. Is there an automatic notification (change alert) system for document updates?​

Automatic notification should be made to relevant users and departments when new version is published.

• Email, ERP notification card, or Slack/MS Teams integration
• Notification content: document name, old and new revision, change summary, effective date
• User completes record with "read/approved" feedback

27. Is archiving and access plan defined after product end-of-life (EOL)?​

When product production ends, document retention period and access policy should be determined.

• Retention period: minimum 10 years (including CE/UL documents)
• Access level: open only to quality management and legal audit units
• Post-EOL revisions are locked (no-edit mode)
• Archive access: "EOL Archive Repository" or "Vault System"
