• Nothing in this Information Guide shall be construed as giving your

company contractual coverage or direction whether expressed or

implied. If there are any conflicts between the language in this booklet

and the language in your contract the language in your contract will

prevail. Your contract contains the entire agreement of the parties and

supersedes any and all prior agreements, understandings and

communications between Buyer and Seller related to the subject

matter of your specific contract.


Scope/Purpose of GuideScope/Purpose of Guide

Scope• This guide outlines primarily “high risk” hardware purchases

• Lower risk hardware may not require every step outlined

Purpose• The purpose of this guide is to help users successfully navigate

their way through the Quality Requirements contained within the Purchase Contract

• It will provide users with an understanding of:• The quality philosophy in establishing and meeting

requirements• Steps in the process• Tips on successful accomplishment of quality

requirements• Most frequent rejections• Acronyms and language used


Quality Requirement ElementsQuality Requirement Elements

• The Purchase Contract is used to communicate Quality

Requirements to suppliers which includes the following:

1. The elements:A. Characteristic Risk Analysis Worksheet (optional based

upon program requirements)

B. Procured Product Acceptance Requirements (PPAR) or Supplier Technical Requirements (STR)

• Includes Characteristic Accountability Worksheet based upon program requirements

2. Quality Clause Provisions


PhilosophyPhilosophy

1. Spending time up front understanding requirements,

assessing risk, and establishing proper controls

improves quality, safety and First Time Through

success

2. Prevention costs should be in proportion to benefit

• Higher safety, cost, and schedule risk warrants

higher prevention costs

3. Working together and good communication delivers

a better result for everyone


Operating PrinciplesOperating Principles

1. Communication, knowledge and planning between all

stakeholders up front is critical to Supplier, Procurement,

Quality, Integrated Product Team and Product Acceptance

2. Utilize available data, knowledge, and experience to

understand operational and manufacturing risks

associated with using/building/processing hardware

3. Assure proper controls are in place to mitigate those risks

before production begins

PWR QE Identifies Product Acceptance RequirementsPWR QE Identifies Product Acceptance Requirements

1. Hardware need is identified

2. Hardware is classified:

• High risk

• Low risk

3. Based on risk level, varying levels of inspection

requirements are applied

4. Pratt & Whitney Rocketdyne Inspection

Requirements are located in the Procured

Product Acceptance Requirements (PPAR or

STR)

PWR Performs Risk AssessmentPWR Performs Risk Assessment

PWR performs initial Characteristic Risk Assessment (CRAW)


21. The most critical characteristics are identified

2. Critical characteristics are those drawing or specification

requirements which if nonconforming:

• Lead to SSME explosion and therefore loss of life and Shuttle

3. Potential process pitfalls are identified with their impact

4. Risk is assessed to determine

• The likelihood of ‘Occurrence’ of the nonconformance

• The ‘Severity’ of risk if the nonconformance occurs

• Ability to ‘Detect’ the flaw before the hardware is used

5. High risk numbers require more control

6. The Preliminary CRAW is performed by PWR

AcronymsAcronyms


Approved Source List (ASL) ASLs identify the sources of supply from which materials or standard parts controlled by designated PWR specifications may be procured. The supplier should use only those suppliers listed on the Approved Source List for those materials or parts.

Activity Guide List (AGL)Government source inspection flow down from the customer. These are Government mandatory inspection points and must be identified in AGL report. They are required typically on NDT inspections Radiographic, and Penetrant inspections. If the government representative asks for inspections other than specified on the AGL and PPAR, contact the buyer.

Buy-To Package (BTP) The Buy-To Package is a collection of all the information and requirements needed to produce and identify an article of hardware. The BTP contains the Procured Product Acceptance Report with the embedded Characteristic Accountability Worksheet or Supplier Technical Requirements.

Certified Special Process (CSP) Certified Special Process (CSP) are designated processors to perform special processes. CSP’s are designated as such on the cover of the specification for PWR designed specifications. Approved processors will be found through Supplier Portal. Although suppliers must be chosen from the list their work must be managed by the prime contractor who has ultimate responsibility for the work performed. If the supplier has another vendor that they prefer to work with they must submit that name to PWR for approval.

Glossary


Characteristics Accountability Worksheet (CAW)Characteristics Accountability Worksheet is used to identify the most critical product characteristics and manage their production to preclude nonconformance. Characteristics are identified and controls applied to assure that hardware is built right the first time through.

Characteristics Risk Analysis Worksheet (CRAW)Characteristics Risk Analysis Worksheet is a form and process for assessing the riskassociated with the variation of individual product characteristics. When such variations could result in a significant, adverse effect on product quality, special controls must be instituted to mitigate the risk. Characteristics that receive a high risk number are transferred to the CAW to identify and approve controls.

Classification of Characteristics (C of C) (SSME program reference:)Classification of Characteristics is a method of recognizing characteristics that have been determined to pose some operating risk, as identified in the FMEA/CIL, in order to properly control their manufacture and inspection. Characteristics are classified as:

Critical: It is in the FMEA/CIL and this is the last time we have to assure conformancePrimary: It is in the FMEA/CIL and this is the next to last time we have to assure conformanceSignificant: It is not in the FMEA/CIL but poses some manufacturing risk

Glossary


Certificate of Conformance (C of C)A document provided by the supplier that assures all drawing and specification requirements have been met.

Critical Items List (CIL)List of critical components that if built improperly may result in catastrophic failure and the inspections that assure proper build.

Electronic Certificate of Conformance (E C of C)The Electronic method of submitting a Certificate of Conformance through the Supplier Portal and any applicable required documentation/certifications/inspections & tested required to validate the purchase as defined by the purchase contract.

Failure Modes and Effect Analysis (FMEA)An assessment performed to understand which hardware conditions may lead to failure.

Government Mandatory Inspection Points (GMIPs)Inspection points that are imposed by the Government (NASA) and verified by local DCMA personnel.

Inspection Discrepancy and Correction ReportA document used to report and correct hardware/documentation that violates drawing or specification requirements.

Glossary


Notice Of RejectionA document used to return procured product to a Supplier. The form is required to be submitted back to PWR with the return of the corrected product.

Process Characteristics Accountability (PCA)The PCA is used to enhance the level of control for selected processes. These documents are required to document actual sequence and nature of manufacturing, inspection, and in-process controlled operations required to ensure the integrity of the process or inspections method.

Process Change Board (PCB)This procedure establishes the basic system requirements for managing changes to customer and internal baselined documents that control the physical or functional characteristics or processes of our products. Program specific requirements/procedures are defined in the program specific Program Appendices identified below. These appendices shall comply with the basic requirements defined in this procedure.

Rejection Tag Used to document nonconformances found by PWR during the Source or Receiving Inspection Process including Electronic Certificate of Conformance as applicable.

Supplier Material Processing ProcedureThe SMPP is used to document the actual sequence and nature of manufacturing, inspection, and in-process control operations required to ensure the integrity of the process or inspection method.
