1. Supplier Overview of Johnson & Johnson MD&D Supplier Quality Standard Operating Procedures (SOPs) Cascade of Specifications and CTQs* to Suppliers
*CTQ – Critical to Quality 1

2. Purpose of this SOP MD&D
To cascade Critical to Quality (CTQ) requirements from the device level down to the component and dimensional/functional level,
ensuring the supplier is aware of them and
that they are integrated and controlled within the supplier’s manufacturing process
The key expectation is that suppliers monitor and control the CTQs within their process

3. Scope
The SOP begins with known MD&D product specifications and critical (CTQ) characteristics required for the function of the device and ends with the capture of those characteristics in the supplier’s specifications and control plans
This SOP is not about how to establish MD&D specifications and CTQs
This SOP is about ensuring that known MD&D specifications and CTQs are integrated and controlled in the supplier’s process

4. Responsibilities MD&D Suppliers
Ensure SOP requirements are met (in procedures & by suppliers)
Communicate CTQs, specifications and risks to suppliers
Ensure that specifications, CTQs and risks are captured in the appropriate quality system documents
Suppliers
Understand MD&D CTQ requirements
Ensure that specifications and CTQs are captured in appropriate documentation
Integrate robust practices for monitoring and controlling CTQs

5. Key Terms
CTQs (Critical to Quality): Attributes that are critical to acceptable performance of a product, process, component, etc.
Specifications: Attributes of products, processes, components, etc. defined to meet customer needs and expectations

6. Key Requirements - Prerequisites
Prerequisite - In advance of cascading CTQs and specifications to suppliers, MD&D Operating Companies will identify product specifications and CTQs following procedures outside of this SOP. A team approach will be used, with suppliers involved where appropriate.
Product specifications and CTQs will be captured in formal documentation (such as drawings)
Specifications and CTQs shall be reviewed during development in technical review sessions or other stage‐gate milestones
The team will establish CTQs and specs for the product/process
CTQs/specs will be translated into any needed additional technical requirements. Suppliers will be involved in this process, as needed.
Specs and CTQs will be established at the product/process, sub-assembly and component level, as needed.
Completed specs will be reviewed to confirm which specs are critical. Documentation will indicate which dimensions are critical.

7. Key Requirements (continued)
Documented specifications, technical requirements and CTQs, will be clearly communicated to suppliers for use in their internal specifications, product/process control plans, etc.
This can be done using Requirements Reviews, drawings, etc.
Applicable device features will be reviewed with suppliers in order to provide an understanding of functionality and risks
This may include a review of the overall device and its performance. It is important that the supplier knows the device and the risks that the products the supplier is providing could pose to the functionality of the device. It is important that the most severe failure modes are communicated to suppliers.

8. Key Requirements (continued)
Specs and CTQs will be translated into the supplier’s documents, including Control Plans and Risk Management documents (such as FMEAs), to ensure there are methods to monitor these items throughout the life of manufacturing.
Specifications/CTQs, technical requirements, critical specifications, etc. must be reviewed periodically by the supplier, to ensure they are current
Updates may be required
Revisions must be communicated to the MD&D Operating Company, prior to implementation, for appropriate approval
