In an interview or assessment for a product innovation role, you may be asked to demonstrate your concept development skills in a practical way. To ace this challenge, start by clarifying the problem or goal. Ask questions to understand the context, scope, constraints, and criteria for success. Then use brainstorming techniques such as mind mapping, SCAMPER, or 6-3-5 to generate ideas. Don't judge or filter your ideas at this stage. Use tools such as the feasibility-viability-desirability matrix, SWOT analysis, or Kano model to evaluate your ideas based on their feasibility, viability, desirability, and differentiation. Select the best idea which meets the problem or goal and has the most potential for value creation and innovation. Finally, use a simple and clear format such as a storyboard, pitch deck, or one-pager to communicate your concept. Explain the problem, solution, value proposition, and key features and benefits of your concept - use visuals such as sketches, diagrams, or screenshots to illustrate it. Concept development is essential for product innovation - following these steps will help you show employers your skills and stand out from the crowd.
