Requirements driven feature development process

A method for developing features to be included in an automobile design, said method comprising:

• capturing an idea for a feature to be developed;
• developing high level requirements for the feature;
• developing detailed requirements for the feature;
• developing mathematical models based on the detailed requirements, using only approved data items from a data dictionary;
• defining hardware components for the feature;
• developing and testing the hardware components for the feature in a vehicle;
• and
• developing a feature technical specification.

A method for developing features to be included in a product design, said method comprising:

• capturing an idea for a feature to be developed;
• developing high level requirements for the feature;
• developing detailed requirements for the feature, including functional requirements, non-functional requirements, and para-functional requirements;
• developing mathematical models based on the detailed requirements, using only approved data items from a data dictionary;
• generating software functional blocks from the mathematical models;
• defining hardware components for the feature including testing the hardware components in a hardware-in-the-loop simulator, and detecting operational limits of the components;
• developing and testing the hardware components for the feature in a prototype of the product;
• and
• developing a feature technical specification.
