Using "Sales" as an example, the auditor would interview personnel concerning the process inputs, activities, and outputs. And examine a sampling of records (required by sec. 8.2.3.2) used to provide evidence of a contract/order review having been performed (with its results) and any records created to describe any new requirements for the products and services (e.g., Change Orders, Amended/Revised Orders). | Using "Sales" as an example, the auditor would: |

A “Product Audit” is performed with the objective of verifying whether a particular product (e.g., parts or assemblies, processed material, software) conforms to requirements (i.e., drawings, BOMs, technical specifications, product/material standards). | A “Product Audit” is performed with the objective of verifying whether a particular product (e.g., parts or assemblies, processed material, software) conforms to requirements (i.e., drawings, BOMs, technical specifications, product/material standards). |

<note>A similar approach could be taken when performing a service-related audit (e.g., laboratory analysis, destructive or non-destructive testing, calibration services, repair services). However, the focus would generally be on the specification(s) defining the required service.</note> | <WRAP center round info 80%> |

<note important>A “[[articles:source_inspections|Source Inspection]]" is NOT a "Product Audit" (or a “Supplier Audit”) because it is an “__inspection__” (not an audit). Unlike a Supplier/Product Audit (which follows a product through its entire production process – verifying that requirements have been met), a Source Inspection takes place at the end of the production line. A Source Inspection "can" replace the Receiving Inspection performed by the customer.</note> | <WRAP center round important 80%> |

These audits should begin by identifying the particular product(s) that the customer is purchasing from the supplier. If the company has any specific product/service-related concerns, then these should be considered when planning the audit. | These audits should begin by identifying the particular product(s) that the customer is purchasing from the supplier.

While all of the above-listed audit types have an objective of verifying "compliance". a "Value-Added Audit" (VAA) focuses on improvement through the elimination or reduction of non-value-added (NVA) activities/steps in a sequence. | While all of the above-listed audit types have an objective of verifying "compliance". a "Value-Added Audit" (VAA) focuses on improvement through the elimination or reduction of non-value-added (NVA) activities/steps in a sequence. |

"Value-Added Audits" are performed "internally" and tend to be used by companies who have adopted the use of Lean 6 Sigma tools. | "Value-Added Audits" are performed "internally" and tend to be used by companies who have adopted the use of Lean 6 Sigma tools. |
