1. Electric Toothbrush Team #2: Kaitlyn Benson Keith Means Carrie Tedesco Joe Velesig

2. Identify the problem Make an electric toothbrush “travel friendly” Assess customer needs/refine project goals e.g. battery life, effectiveness, bristle variety Preliminary design and evaluation Created/sketched initial design ideas Outline

3. Worked as a team Divided work for time management Worked outside of class Communicated effectively to maintain project goals FFM Personality comparison Project Management
