Software Development

Software development supports the incremental development of features that can be delivered to streams or other stakeholders. Included are design, implementation, unit tests, component tests, and bug fixing. Software development can result in deliverables, e.g., firmware, applications, and tools.

For embedded systems, the software or firmware is dependent on the hardware, and the software and hardware processes need to be tightly integrated.

Process Overview​

Principles​

  • Design and document the solution parallel with the code. Use design patterns for classes and methods​.
  • Plan for providing secure code.
  • Commit code frequently, preferably daily, to ensure quality and development speed​.
  • Protect the code base with automated unit tests, component tests, static code analysis, and code reviews applied before acceptance​.
  • Ensure consistency and traceability from requirements and architecture to design code and test​.
  • Continuously refactor and refine the design, code, and tests to reduce technical debt​.
  • Provide input to end-user documentation.
