Final answer:
The next stage in product development for Starbucks after assessing consistency with objectives and resources is 'concept testing,' followed by 'business analysis' and potentially 'test marketing,' depending on the outcomes of earlier stages.
Step-by-step explanation:
The next stage of development for the remaining product ideas, after the Starbucks management has assessed consistency with the company's objectives and resources, is concept testing. Concept testing involves presenting the product idea to potential consumers and obtaining their feedback. This stage is vital to understand the consumer's response to the concept before committing to a full-scale product development. After gathering data from potential customers, a business analysis is typically conducted to assess the potential product's profitability and fit within the company's overall strategy. If the feedback is positive and the business analysis shows a favorable outcome, the product may move into test marketing, where it is introduced to a limited market to evaluate its performance in a real-world setting.
Throughout the process, designers and marketing teams will brainstorm alternative solutions, refine the design through prototyping, testing, and refinement, and select a design concept via a structured decision process to meet the product requirements and constraints. Should any design concept not suffice during the prototyping or testing phases, the process circles back to initial stages of concept generation and design refinement.
