What advantages and weaknesses do competing products and services have?; What are the barriers for your idea to gain a foothold?

For this course project, small class group came up with an entrepreneurial and innovation product idea. This product idea is baby diapers with built in pH (and perhaps electrolyte) indicator strips to advise parents/caregivers of potential health and nutritional issues with their baby.

Address competition in the following areas:
I. Who else serves this customer/audience need?
II. What advantages and weaknesses do competing products and services have?
III. What are the barriers for your idea to gain a foothold?
IV. What are the barriers to entry for additional competitors/solutions?
