Contract Software & Firmware Development

Experience & expertise to accelerate your project

DelSys, Inc. is Doug Barton’s contract software and system development services company. I specialize in mission critical, high reliability development and have completed many successful projects for clients including Johnson & Johnson and Siemens Diagnostics.

For some projects, most of the work is done at the client site working with their staff. For other projects, much of the work is done off site.

Client engagements are typically for three months to one year. But a number of clients have retained DelSys for multiple projects over many years.

Disciplined Methods Deliver Quality Results

DelSys has a thorough, practical understanding of how to complete successful projects:

  • Meet the client’s goals and their customer's needs.
  • Define requirements that facilitate efficient development and testing.
  • Establish and meet meaningful milestones to inspire confidence.

  • Write readable, well commented code that's easy to maintain and enhance.
  • Test effectively throughout the project — unit, verification & validation.
  • Write useful documents that inform current and future developers.

For a J & J subsidiary, DelSys developed the embedded firmware for three generations of an intravenous medical instrument over a period of 10 years. These instruments were remarkably reliable – zero software defects were identified in the field.

Client Solutions

Unified Code Base Reduces Cost

A client had a number of similar embedded system products, each with its own code base. Over time, we migrated them to a single code base, reducing maintenance costs.

Diagnostic Interface Increases Quality

For a medical instrument, DelSys designed an integral diagnostic interface that allowed the hardware to be monitored as the instrument ran normally. Initally intended as a software diagnostic tool, this interface was ultimately used for hardware debugging and production testing as well.

QA & Project Management Facilitate Success

DelSys was retained to conduct acceptance testing for a complex medical system developed for our client by an outside vendor. The system had promise but also numerous hardware and software defects. We wrote test plans and coodinated development projects with the vendor that helped the system become a major success for our client.
