In most companies, the Product Change Notification (PCN) agreement is primarily led and signed by the Quality or Engineering department, but other departments such as Legal, Sales, and Procurement may also be involved. Below is a breakdown of responsibilities:
Primary Responsible Departments
1. Quality Department (QA / Quality Management)
This is typically the lead department because:
-
They are responsible for product consistency and change control
-
They understand customer requirements regarding change notifications (e.g., PPAP, FAI)
-
They can evaluate the technical impact and manage validation processes
2. Engineering / R&D Department
When the change involves design, material, or process modifications:
-
Engineering defines the change content and impact assessment
-
They work with customers to evaluate and approve the technical details
Supporting Departments
3. Sales / Key Account Management
-
Facilitates communication with the customer
-
Coordinates timing and customer approval for changes
-
Understands PCN clauses in customer contracts, including notification lead time
4. Legal Department
-
Reviews legal liability, indemnity clauses, and notification obligations in the PCN agreement
-
Ensures compliance and minimizes contractual risks
5. Procurement Department (if applicable)
-
In cases where the company is a tier-1 or tier-2 supplier, procurement may need to ensure upstream suppliers also follow PCN procedures
Practical Recommendations
-
For key customers (e.g., in automotive, medical, aerospace industries), it's advised to include PCN terms as part of the main contract or as an annex to the quality agreement
-
The agreement should clearly specify:
-
What types of changes require notification
-
Notification timelines (e.g., 90 days, 180 days)
-
Whether the customer has the right to approve or reject changes
-
Responsibilities and liabilities for unauthorized or unnotified changes (e.g., fines, returns, compensation)
-
Summary
The PCN agreement is usually signed by the Quality or Engineering department, with support from Sales, Legal, and Procurement as needed.
In a PCN (Product Change Notification) agreement, the following types of changes—if not properly notified or approved—can typically result in penalties, fines, or claims from the customer. This is especially true in industries with strict quality and compliance requirements, such as automotive, medical, electronics, and semiconductors.
1. Material Changes (BOM Changes)
-
Replacement or substitution of key raw materials or components
-
Changes in suppliers without prior approval
-
Component upgrades or replacements due to EOL
Risk: Product performance deviation, batch quality issues, rejection by customer.
2. Manufacturing Process Changes
-
Process flow adjustments, addition/removal of steps
-
Changes in soldering, coating, or assembly methods
-
Switching between manual and automated processes
Risk: Decreased consistency, fluctuating defect rates, revalidation may be required.
3. Production Site Relocation
-
Factory relocation or adding new production lines
-
Change of outsourced factories (e.g., EMS providers)
Risk: Inconsistent quality systems, PPAP or revalidation often required.
4. Critical Equipment Changes
-
Replacement of molds, jigs, or key production equipment
-
Updates to software or testing equipment
Risk: Affects dimensional accuracy or testing consistency; may require new sample approval.
5. Packaging or Labeling Changes
-
Changes to packaging materials, structure, or label content
-
Barcode format or batch number modifications
Risk: Logistics issues, scanning failures at the customer’s warehouse, product returns.
6. Product Design Changes
-
Modifications to product structure, functionality, or interface
-
Software/firmware version updates
Risk: Re-certification required, and unapproved changes may violate contract terms.
7. Product Discontinuation (EOL Notification)
-
Failure to notify customers within the agreed lead time (e.g., 12 months)
Risk: Customers may claim compensation for supply disruptions or redesign costs.
8. Changes in Delivery Conditions
-
Lead time extensions, minimum order quantity (MOQ) changes, price adjustments
Risk: Breach of framework agreements; customers may impose penalties or file claims.
Panchayat Season 4 has been officially released and is streaming exclusively on Amazon Prime Video.
While it's understandable to look for free options, searching for "Telegram download links" for copyrighted content like web series is generally related to piracy, which is illegal and unethical. It also carries risks like malware and poor quality.
Here's how you can watch Panchayat Season 4 legally and safely in Hindi:
- Amazon Prime Video Subscription: This is the primary and official way to watch Panchayat Season 4. You will need an Amazon Prime Video subscription.
- Telecom Offers: In India, many telecom providers like Jio, Airtel, and Vi offer bundled plans that include a free Amazon Prime Video subscription. You can check your current mobile plan or explore new plans from these providers to see if you can get Prime Video for free as part of your recharge.
Why avoid unofficial sources like Telegram for downloads:
- Illegality: Downloading copyrighted content without proper authorization is illegal.
- Malware/Viruses: Unofficial download links often contain malware, viruses, or other harmful software that can damage your device or steal your personal information.
- Poor Quality: Pirated versions often have low video and audio quality, missing scenes, or incorrect subtitles.
- Supporting Creators: Watching on official platforms supports the creators, actors, and crew who put in a lot of effort to make the show.
