One of the keys to a successful project is a complete and thorough upfront engineering specification. In developing a specification we leverage our cross-functional system knowledge to work with the client and the driving Marketing Requirements Document (MRD) to jointly specify a solution. A clear and concise engineering specification or Engineering Requirements Document (ERD) ensures that all project expectations are met or exceeded.DDG's Specification services include:

Electronic Systems

DDG excels at architecting turnkey electronic systems and subsystems, in particular, embedded systems(field-portable, space-constrained, UAV, battery-powered). These systems are typically characterized by real-time constraints and dedicated to a particular task or mission. Overall architecture requires a multi-discipline approach that carefully partitions firmware and hardware responsibilities and requirements. Its paramount that the architecture and partitioning of work load be allocated optimally and efficiently to ensure that designs are able to deliver to goals and expectations. DDG emphasizes modularity, configurability, and scalability in system architecture. By doing so, we maximize design re-use and avoid dead-end development.

Verification & Validation

During Verification and Validation, DDG works closely with the client to ensure engineering specifications and end user expectations are met. DDG has defined a disciplined three-step re-iterative process for verification and validation:

1. Test to Specification:

The first step in the verification and validation process involves checks to see if the design meets all the requirements called out by the specification (typically the ERD).

2. Test for System and End User Compatibility

The second step in the verification and validation process emphasizes maximizing exposure to different manufacturers/models/configurations to ensure the design functions as expected in the various systems and meets all end user needs. This step may include demos, trials, and acceptance testing.

3. Test for Standards and Agency Compliance

The third step in the in verification and validation process is the final step prior to release to production. Final certifications to applicable industry standards and EMC/safety formal compliances are obtained.
