Explanation
The design team should provide a breakdown of the strategy, linking features with consumer benefits and outcomes, to address the concerns of the executive team. This helps communicate the value proposition and rationale of the product vision, and how it aligns with the business goals and objectives. References:

Before framing the problem, the strategy designer should ask what problem(s) CK is trying to solve, rather than jumping to solutions or assumptions. This helps clarify the scope and context of the challenge and identify the root causes and effects of the issue.

The strategy designer should conduct an expert interview in consumer device engineering to determine whether or not to pursue this product idea. An expert interview is a way to gather information and insights from someone who has specialized knowledge or experience in a relevant domain. It can help validate assumptions, identify risks, and explore opportunities for innovation. Performing secondary research may not provide enough depth or specificity for this product idea. Hiring an engineer may be premature and costly at this stage.

Some safeguards that should be put in place to ensure the research is conducted ethically are a code of conduct, ethics training, and a research data handling policy. A code of conduct is a set of principles and guidelines that define ethical behavior and expectations for researchers and participants. Ethics training is a way to educate researchers on ethical issues and best practices in conducting research. A research data handling policy is a document that specifies how research data will be collected, stored, accessed, shared, analyzed, and disposed of in a secure and compliant manner. A customer journey map, research scenario, and a RAID log are tools for planning and documenting research activities, but they do not address ethical issues. A hypothesis, project plan, and financial reimbursement for users are elements of research design and execution, but they do not ensure ethical conduct.

The best focus for testing efforts to determine whether to produce a product at scale is desirability, viability, and feasibility, which are the three key dimensions of design thinking that evaluate whether a product is desirable for users, viable for business, and feasible for technology. Novelty, privacy, and potential to go viral or competitive advantage, impact, and own ability are not comprehensive enough to cover all aspects of design thinking.
