How We Do It

In terms of processes and tools, DEI’s focus is on high quality design and development.

In order to get it “right the first time” DEI makes extensive use of project planning, simulation, CAD, firmware and software development tools to speed up development and minimize time and cost.

At a minimum, a functional specification is prepared prior to design (technical uncertainties are removed at the initial stage using proof of concept breadboards) and the system or product is verified to ensure that it meets the specified requirements. The development methodology of each project is tailored to the clients’ requirements.

We work on a fixed price or hourly basis as appropriate for the project and as preferred by the client.

Quality Procedures & Controls

Quality, meeting the requirements and expectations of our customers and industry standards, is the core of what we do at DEI.

Our Quality Manual defines the project process, documents and drawing numbering/revisions, coding standards, software revision control, design guidelines and checklists, design change process, etc.

We have successfully developed products and systems to a wide range of industry standards: FDA (radiopharmaceuticals), Nuclear (irradiators), Military (US Army, Marines, DND), Medical devices, FCC, and UL.
