Arrange the following steps in correct order of design thinking process for developing a sustainable packaging prototype:
A. Create prototypes using sustainable packaging materials
B. Interview consumers and stakeholders to understand the packaging needs and demands
C. Define problems like cost, durability and environmental impact from research insights
D. Test prototype for usability and environmental impact assessment
E. Brainstorm alternative packaging ideas that balance sustainability and functionality
Choose the correct answer from the options given below:

Correct option is C

The process starts with Interviewing consumers and stakeholders (B). This stage represents the Empathize phase, where designers deeply understand user needs, expectations, pain points, and sustainability concerns related to packaging.
Next is Defining the problem (C). Based on research insights, key issues such as cost-effectiveness, durability, waste reduction, and environmental impact are clearly articulated. A well-defined problem ensures focused and relevant solutions.
This is followed by Brainstorming alternative ideas (E). In the Ideation phase, multiple creative solutions are generated that balance sustainability with functionality, encouraging innovation without constraints.
After ideation, Prototyping (A) takes place. Here, selected ideas are converted into tangible packaging prototypes using eco-friendly materials to explore feasibility and performance.
Finally, Testing and evaluation (D) are carried out. The prototype is assessed for usability, consumer acceptance, and environmental impact, allowing refinements and improvements.
Thus, option (c) correctly reflects the structured and iterative nature of design thinking.
Information Booster:
· Design thinking is a human-centered and problem-solving approach.
· Empathy is the foundation of sustainable product development.
· Problem definition guides effective ideation.
· Prototyping helps visualize and test ideas early.
· Testing ensures real-world applicability and sustainability impact.
