Product Integration: An Engineering Process Area at Maturity Level 3


The purpose of Product Integration (PI) is to assemble the product from the product components, ensure that the product, as integrated, behaves properly (i.e., possesses the required functionality and quality attributes), and deliver the product.


To achieve problem-free integration, you need to prepare for product integration activities early in the project.

Introductory Notes

This process area addresses the integration of product components into more complex product components or into complete products.


In some engineering disciplines (e.g., mechanical engineering), the term assembly is generally preferred over integration. In PI, these two words are ...
