The purpose of Product Integration (PI) is to assemble the product from the product
components, ensure that the product, as integrated, functions properly, and deliver the

1. Prepare for Product Integration

1. Identify the product components to be integrated.
2. Identify the verifications to be performed during the integration of the product
3. Identify alternative product component integration sequences. (This can include
defining the specific tools and test equipment to support the product integration).
Select the best integration sequence.
4. Periodically review the product integration sequence and revise as needed

2. Establish the Product Integration Environment
1. Identify the requirements for the product integration environment.
2. Identify verification criteria and procedures for the product integration environment.
3. Decide whether to make or buy the needed product integration environment. (Refer to
   the Supplier Agreement Management process area for more information about
acquiring parts of the integration environment).
4. Develop an integration environment if a suitable environment cannot be acquired. (For
unprecedented, complex projects, the product integration environment can be a major
development. As such, it would involve project planning, requirements development,
technical solutions, verification, validation, and risk management.).
 5. Maintain the product integration environment throughout the project.
 6. Dispose of those portions of the environment that are no longer useful.

 3. Establish Product Integration Procedures and Criteria
  Procedures and criteria for product integration address the following:

 Level of testing for build components
 Verification of interfaces
 Thresholds of performance deviation
 Derived requirements for the assembly and its external interfaces
 Allowable substitutions of components
 Testing environment parameters
 Limits on cost of testing
 Quality/cost tradeoffs for integration operations
 Probability of proper functioning
 Delivery rate and its variation
 Lead time from order to delivery
 Personnel availability
 Availability of the integration facility/line/environment

4. Ensure Interface Compatibility
The product component interfaces, both internal and external, are compatible.

5. Review Interface Descriptions for Completeness
1. Review interface data for completeness and ensure complete coverage of all interfaces.
(Consider all the product components and prepare a relationship table. Interfaces are
usually classified in three main classes: environmental, physical, and functional. Typical
categories for these classes include the following: mechanical, fluid, sound, electrical,
climatic, electromagnetic, thermal, message, and the human-machine or human
2. Ensure that product components and interfaces are marked to ensure easy and correct
connection to the joining product component.
6. Manage Interfaces
1. Manage internal and external interface definitions, designs, and changes for products
and product components.
(Interface requirements drive the development of the interfaces necessary to integrate
product components. Managing product and product component interfaces starts very
early in the development of the product. The definitions and designs for interfaces affect
not only the product components and external systems, but can also affect the verification
and validation environments.)
2. The interfaces should include, in addition to product component interfaces, all the
interfaces with the environment as well as other environments for verification, validation,
operations, and support.
3. Ensure the compatibility of the interfaces throughout the life of the product.
4. Resolve conflict, noncompliance, and change issues.
5. Maintain a repository for interface data accessible to project participants.

7. Assemble Product Components and Deliver the Product

1. Verified product components are assembled and the integrated, verified, and validated
   product is delivered.
2. Integration of product components proceeds according to the product integration
   sequence and available procedures. Before integration, each product component
   should be confirmed to be compliant with its interface requirements. Product
   components are assembled into larger, more complex product components. These
   assembled product components are checked for correct interoperation. This process
   continues until product integration is complete. If, during this process, problems are
   identified, the problem should be documented and a corrective action process
8. Confirm Readiness of Product Components for Integration
1. Confirm, prior to assembly, that each product component required to assemble the
   product has been properly identified, functions according to its description, and that
   the product component interfaces comply with the interface descriptions.
2. Track the status of all product components as soon as they become available for
3. Ensure that each received product component meets its description.

9. Assemble Product Components

1. Ensure the readiness of the product integration environment.
2. Ensure that the assembly sequence is properly performed.
3. Revise the product integration sequence and available procedures as appropriate.

10. Evaluate Assembled Product Components

1. Evaluate assembled product components for interface compatibility.
2. Refer to the Verification process area for more information about verifying assembled
   product components.
3. Refer to the Validation process area for more information about validating assembled
   product components.
11. Package and Deliver the Product or Product Component

1. Package the assembled product or product component and deliver it to the appropriate
2. Refer to the Verification process area for more information about verifying the
   product or an assembly of product components before packaging.
3. Refer to the Validation process area for more information about validating the
   product or an assembly of product components before packaging.
