Consider your case company, the known customers, environments, strategies, discovery techniques, and solutions. Now consider- how did they design the product(line) to achieve their goals of value, feasibility, viability, and usability? What techniques and trade-offs were considered as the product moved from idea to concept (to production specs) to prototypes?
What were the ideation techniques were used? What kinds of divergent and convergent thinking are evident?
(MVPs or early versions can help here if there is no data)
What concepts were produced or explored? Some questions you might answer are:
Were there clear sets of requirement types?
What types of elemental (bottom-up) approaches were used?
What types of system-level concerns were solved for?
What metrics drove design?
How were concepts elaborated to achieve product specs?
What type of trade-offs were evaluated for?
What key features were left out of the final design? Why?
What kinds of tests might you have run to refine from the ideal concept to the real manufacturable product?
What kinds of Design For X considerations existed? Such as:
Design for manufacturing, environment, assembly, etc.
For software design for platform, supportability, scalability, extensibility, and traceability
For hardware design for production, maintenance, sustainability, etc.
What types of prototyping to support large-scale production?
How was the final design analyzed for performance in terms of cost and sustainability?
