Lessons Learned: Design Transfer

Lessons Learned: Design Transfer by Chuong Tran

This document captures and summarizes key lessons learned during my design transfer projects. Its purpose is to provide actionable insights for future projects, improve efficiency, and mitigate potential risks. 

1. Early & Frequent Communication:

• Best Practice: Establish cross-functional teams early, hold regular meetings, use clear communication channels.

• Pitfall: Siloed teams, late-stage communication, unclear expectations.

2. Design for Manufacturability (DFM):

• Best Practice: Integrate DFM from concept, involve manufacturing in design reviews, prioritize manufacturability.

• Pitfall: Design finalized without manufacturing input, complex designs, difficult assembly.

3. Robust Documentation:

• Best Practice: Maintain detailed, accurate, and accessible documentation (drawings, specs, work instructions).

• Pitfall: Incomplete, inaccurate, or scattered documentation, version control issues.

4. Thorough Validation & Verification:

• Best Practice: Conduct comprehensive IQ, OQ, PQ, pilot runs, and MSA.

• Pitfall: Rushed validation, inadequate testing, assumption-based approvals.

5. Proactive Risk Management:

• Best Practice: Perform FMEA early, identify potential risks, implement mitigation plans.

• Pitfall: Reactive problem-solving, ignoring potential failures, inadequate risk assessment.

6. Controlled Change Management:

• Best Practice: Implement a formal change control process, document all changes, obtain approvals.

• Pitfall: Uncontrolled changes, undocumented modifications, lack of traceability.

7. Effective Training & Knowledge Transfer:

• Best Practice: Provide comprehensive training, conduct knowledge transfer sessions, ensure operator competency.

• Pitfall: Inadequate training, assumptions about operator knowledge, poor knowledge transfer.

8. Scalability & Capacity Planning:

• Best Practice: Consider scalability early, assess equipment capacity, plan for future production.

• Pitfall: Underestimating production volume, ignoring equipment limitations, neglecting material availability.

9. Material Traceability:

• Best Practice: Implement robust material traceability systems.

• Pitfall: Inability to locate faulty material, increased risk of recalls.

10. Supplier Management:

• Best Practice: Select reliable suppliers early, establish clear communication, ensure material quality.

• Pitfall: Late supplier selection, poor communication, material quality issues.

11. Continuous Improvement:

• Best Practice: Implement feedback loops, monitor process performance, use SPC, conduct regular reviews.

• Pitfall: Stagnant processes, ignoring feedback, lack of data analysis.

12. Clear Acceptance Criteria:

• Best Practice: Clearly define acceptance criteria for each stage of transfer.

• Pitfall: Vague criteria, leading to disagreements and delays.
