Additional programs

Designated Support Engineer (DSE) Program

A DSE is a dedicated remote support specialist and product expert. The DSE serves as a single point of contact for customers and is intimately familiar with the deployment topology and requirements. DSEs manage all cases and have direct access to Synopsys internal teams such as Engineering to expedite time to resolution.

In our program, we match each customer to a DSE who becomes an integral part of the customer's deployment team and offers guidance, planning, and hands-on support. DSEs can offer up to ten hours of service a week to each customer.

Quantifiable benefits

  • Rapid root-cause diagnosis and problem resolution, reduced time to resolution (TTR)
  • Increased customer satisfaction (CSAT) through optimized product deployment 
  • Reduced total cost of ownership (TCO) due to increased uptime, decreased TTR
