HandEra’s product development process is structured to provide consistent development stages across a wide variety of product types. The result is a methodical approach that guarantees on time delivery of quality designs.

Intial Customer Contact:

HandEra discuses the potential project with the customer and collects information about scope, timeline and potential specification requirements.


HandEra delivers a proposal containing estimated development timeline, required resources and costs for customer review.

Initial Investigation:

In this initial phase of the project, the team will perform a variety of tasks in preparation for the start of engineering. These tasks include:
  • Collect product requirements
  • Conduct initial research such as benchmarking
  • Develop system architecture
  • Produce specification document
  • Produce initial industrial design
  • Develop Initial Test Plan
  • Refine project timeline

Engineering Verification Test (EVT):

The purpose of this phase of the project is to produce initial prototypes that may or may not be in the exact shape of the final product. The EVT prototypes are primarily meant for engineering use so that software development can begin, and so that initial electronics testing can be conducted. During the EVT phase, the Test Plan will be refined and a Production Test Strategy will be developed.

Design Verification Testing (DVT):

DVT prototypes are used to carry out comprehensive form-factor testing and to confirm all functionality listed in the product’s specification. DVT units may be manufactured using quick-turn assembly processes that may not be the same as the final supply chain.  Testing during this phase of the project concentrates on functional testing, environmental testing, reliability testing, and compliance testing.

Production Verification Test (PVT):

PVT prototypes are final prototypes that are assembled using the production supply chain. These units can be used for final testing such as final qualification testing, safety agency testing, and regulatory approval testing. Any issues that are identified in final tests are corrected.

Mass Production Start:

This is the final phase of the project and marks the beginning of mass production. HandEra may be involved in this phase to act as a liason and assist the manufacturer with training or other items to transfer the design into production.

Production Support:

This optional phase of the project is used to assist the manufacturer with any repair or yield questions that may developer after Mass Production Start.
