This document provides an overview of the Product Integration process. It aims to increase understanding of the PI process and its procedures. The purpose of PI is to assemble product components, ensure functionality and quality, and deliver the product. It discusses PI's relationship to other processes like requirements management and testing. The document also outlines the 7 steps of PI, including preparing for integration, reviewing interfaces, assembling components, and delivering the product. Contact information is provided for questions about the PI process.

When PI Is Not Done Well…
• Sub-products do not operate together
• Increased integration test time
• The integration environment can be inadequate to
support the integration activities
• Products can be released without component
integration fully tested

8. Product Integration | Solution Engineering8
PI relationship to other processes – 1
• The PI Process is a mandatory process within the CMMI
Engineering Category (IRM 2.120.3)
• The Engineering process areas cover the development and
maintenance activities that are shared across engineering
disciplines
• Engineering processes are both recursive and iterative
• Recursive – Solves a problem by breaking up a task into
smaller and smaller pieces until it can be completed;
combine the results. e.g. Looping algorithms
• Iterative – repeating until a task is completed e.g. a loop
counter reaches a limit

9. Product Integration | Solution Engineering9

18. Product Integration | Solution Engineering18
Planned Maintenance Projects
Maintenance Projects Entering ELC at Milestone Phase 3
• If the project requires acquisition of HW to accomplish the
project’s objectives, adherence to the GEL and PI processes is
required
• Formal evaluations are required for adding new technologies,
new tools, or new products into the IRS IT environments
• Functional Equivalents may be utilized
• Requires an Integration Strategy or sequence
Maintenance Projects Entering ELC at Milestone Phase 4A
• Functional Equivalents may be utilized
• Requires an Integration Strategy or sequence
• No formal evaluations are required

19. PI Tailoring
• The Product Integration process step 1 may be tailored for
projects with modest integration need. These projects may
document an integration sequence with rationale instead
of developing and documenting a full Integration Strategy.
All other PI steps may not be tailored.
• All tailoring requests should be submitted in writing to
Solution Engineering via the Solution Engineering Front
Door.
