Sustaining Engineering & Legacy Support

WHAT WE DO

What Is Sustaining Engineering?

Sustaining engineering encompasses the technical activities that maintain, enhance, and extend the life of products after their initial release to market. Unlike new product development, sustaining engineering focuses on managing existing product performance, resolving issues, and implementing strategic improvements.

For manufacturing companies, effective sustaining engineering is the difference between premature product obsolescence and decades of profitable market presence.
