What is sustaining engineering?

Sustaining engineering is the process of supporting and improving products or systems after their initial release. Professionals in this field focus on maintaining product quality, addressing defects, implementing upgrades, and ensuring long-term reliability. Their work often involves collaborating with design, manufacturing, and customer support teams to resolve issues that arise during a product's lifecycle. Sustaining engineers play a crucial role in extending the value and performance of existing products while minimizing downtime and costs.
