Process

Phase 1

Functional specification

• Refining the user's wishes

• Refining the technical specifications

• If necessary, filling any gaps in the prescribed wishes or specifications

• Domain analysis. Understanding all domain specific parts and how they can influence each other

• Determine focus. Aligning what the focus is on, production costs, development time or quality.

• Capture Critical Components

Phase 2

Conceptual design

• Designing the conceptual solution based on the functional specifications

• Select electrical components based on technical specifications

• Devise and simulate circuits

• Define mechanical mounting principles and determine PCB size

• Set up software architecture (UML Class diagram)

• Set up display wireframe

• Capture housing sketch design

Phase 3

Detail design

• Electronics schematic design

• PCB Layout Designs

• Create and tune mechanical design

• Detailed software design

• Software coding

Phase 4

Realization

• Prototype PCB making

  • Order PCB

  • Order materials

  • Assemble

• Software implementation

• Making a prototype housing

  • 3D printed

Phase 5

Module test

• Electrical Testing Subsystems

  • Verify interface with detail design

  • Verify signals with detail design

• Test software unit

  • Verify interface with detail design

  • Verify process values with detail design

• Testing and Verifying Mechanics with Detail Design

• Bringing hardware and software together at module level

Phase 6

Unit test

• Bringing all submodules together

  • Verify operation with the concept design

  • Verify specifications with the concept design

• System integration with housing

• Verify system requirements with concept design

• Debug and adjust if necessary

Phase 7

User test

• Technical testing

  • Measure signals

  • Verify with functional design

• Functional testing and debugging

  • Test functionality

  • Verify with functional design

• Commissioning the PCB in real-life situation
