Auditing to Sufficient Depth • Why is this important? • ANAB auditors issued over 75 NCRs in 20 areas in 2005-2007 for not auditing to sufficient depth • Many were repeat NCRs • Undermines the integrity of aerospace audits • Serious concern within aerospace community
Auditing to Sufficient Depth • 75 NCRs in these 20 areas
Auditing to Sufficient Depth • Why is this important? • OEMs beginning to conduct validation audits (independent checks of suppliers with AS91XX certifications) • OEMs can (& do) complain directly to ANAB regarding unresolved issues related to CB conformance to established aerospace requirements, including not auditing to sufficient depth • ANAB will respond very promptly (i.e. visit CB office within a few days)
Auditing to Sufficient Depth • What should auditors do? • Understand the requirements to which the audit must be conducted • Research/get training in topics they do not understand • Understand the processes and interactions and involvement of all stakeholders • Understand what objective evidence is required for an auditee to show conformance with a requirement • Accomplish fair, unbiased, detailed audits to the established criteria • Avoid “soft” auditing or “glazing over” topics
Auditing to Sufficient Depth • What will we address in this session? • Document control (including configuration management) • Procurement (including purchasing and supplier control) • Product acceptance software
Auditing to Sufficient Depth Document Control and Configuration Management Requirements (13 ANAB NCRs in this area in the past three years, primarily in configuration management)
Auditing to Sufficient DepthDocument Control 4.2.1 General: The quality management system documentation shall include… f. quality system requirements imposed by the applicable regulatory authorities
Auditing to Sufficient DepthControl of Records 4.2.4 Control of Records • The documented procedure shall define the method for controlling records that are created and/or retained by suppliers. • Records shall be available for review by customers and regulatory authorities in accordance with contract or regulatory requirements.
Auditing to Sufficient DepthControl of Documents and Records Questions on Document and Record Control?
Auditing to Sufficient DepthConfiguration Management 4.3 Configuration Management: The organization shall establish, document and maintain a configuration management process appropriate to the product. Note: Guidance on configuration management is given in ISO 10007
Auditing to Sufficient DepthConfiguration Management What is configuration management? Per ISO 10007: “configuration: interrelated functional and physical characteristics of a product defined product configuration information” “configuration management: coordinated activities to direct and control configuration”
Auditing to Sufficient DepthConfiguration Management What is configuration management? Working level definition: The cumulative actions an organization takes to ensure that the exact status of a unit or component is known at any given time and to ensure that the status is as planned Status refers to the makeup of the unit or component (i.e. which revision is being built?; what pieces or items are in the unit or component?)
Auditing to Sufficient DepthConfiguration Management 4.2.3 Document Control vs. 4.3 Configuration Management: Document control typically addresses controlling procedures, work instructions, contracts and other such documents Configuration management typically addresses controlling a product print or drawing and items that are used to build the product
Auditing to Sufficient DepthConfiguration Management • While we will address configuration management in some detail, ISO 10007 should be available at your registrar • Per AQMS Standards, configuration management process must be documented (may change in next rev) • Configuration management will move to clause 7.1 in next revision
Auditing to Sufficient DepthConfiguration Management Configuration management actions: Technical and organizational activities comprising: • configuration identification • configuration control • configuration status accounting • configuration auditing (next rev adds configuration planning)
Auditing to Sufficient DepthConfiguration Management Configuration Planning • Develop a plan • Describe CM actions, responsibilities and authorities throughout product life cycle Configuration Identification • Identify configuration items • Develop a baseline Configuration Control Define a change methodology Define the information storage procedure
Auditing to Sufficient DepthConfiguration Management Configuration Status Accounting • Gather & record data on a build • Identify deviations Configuration Audits • Functional Configuration Audit • Verifies that a CI meets performance and functional requirements cited in the configuration documentation • Physical Configuration Audit • Verifies that the as-built unit conforms to product configuration documentation
Auditing to Sufficient DepthConfiguration Management Some points an auditor should investigate: • Is the process defined/documented? • Has a CM plan been developed? • Is there a methodology to accomplish CSA? • Are the steps being accomplished? • How are the audits being documented? • Are audit findings being acted upon? • Have roles and responsibilities been defined? • What happens when CM is not maintained?
Auditing to Sufficient DepthConfiguration Management Some points an auditor should investigate (con’t): • How does configuration management ripple throughout the organization (i.e. purchasing, production, repair)? • What impact does a change in supplier or source of a material/component have on CM activities? • Is the CM system comprehensive enough for the product and/or contract flow down requirements? • How are drawings controlled, both while in engineering and after release to the program? • How do engineering changes interface with the configuration management process? • At what point does the CM function take control of the configuration from the design function? • How does this transfer take place?
Auditing to Sufficient DepthConfiguration Management Other questions on configuration management?
Auditing to Sufficient DepthProcurement Addresses supplier control, purchasing and verification of purchased product (10 ANAB NCRs in this area in the last three years)
Auditing to Sufficient DepthProcurement - Supplier Control 7.4.1: The organization shall evaluate and select suppliers based on their ability to supply product in accordance with the organization’s requirements.

Auditing to Sufficient DepthProcurement - Supplier Control 7.4.1: The organization shall: • Maintain a register of approved suppliers that includes the scope of approval How is scope of approval determined? • An example
Auditing to Sufficient DepthProcurement - Supplier Control To identify scope, we divide our suppliers by commodities. The commodities we use are:
Auditing to Sufficient DepthProcurement - Supplier Control Hardware and Software

CMSC Overview Product Acceptance Software (PAS) and Quality System Requirements - Taking Ownership of One's PAS
Agenda • Product Acceptance Software Defined • Processes Affected • PAS Requirements/Guidelines • Mathematical Computation • Validation Methods • Validation Summary • What can you do and why • Questions
Product Acceptance Software Defined • What is Product Acceptance Software (PAS) • PAS is considered software that performs product or tooling acceptance without subsequent inspection • Software used to manage, store, or translate the sole-source authority copies of digital type design, and is able to impact the integrity of the type design • PAS may be commercial off the shelf software
Processes Affected • Common PAS applications include • CMM software • PCMS applications (Laser Trackers, Laser Radar, Laser Scanners, Photogrammetry, PCMM’s) • Optical Laser Templates • CAD data translators • CAD Analysis Software • Post processors
PAS Requirements • FAA AC21-36 (1993) Quality assurance controls for product acceptance software. (FAA Req’mnt) • AS9100 Quality management systems – Aerospace requirements • Section 7.6 • D6-51991 Quality Assurance Standard for Digital Product Definition at Boeing Suppliers • Section3.0
