The Process

Collaborate & Design

Once we have designed the product and received customer approval, we are begin the prototyping process.


After prototypes are approved, we enter the product into full scale production.


Sustaining and supporting the user interface throughout the life of the product. CSI is still supporting products that were originally designed 38 years ago.
