Report II - Opportunity: Market Research and Design Concepts

Executive Summary

Market Research and Observations

In order to determine stakeholder needs we conducted user interviews using the following set of questions:

Choosing the Product

1. How did you select which stethoscope to buy?
2. How did you research your options?
3. What factors played the biggest role in your choice?

Using the product

1. How were you taught to use this equipment (in a class, on the job, etc.)?
2. Do you warm up, clean the face of, or do anything else to the stethoscope prior to using it on a patient?
3. Does your stethoscope perform equally well in all conditions (temperatures, background noises, etc.)?
4. How often do you buy a new stethoscope? Why do you buy a new one?
5. What type of maintenance operations do you perform on your stethoscope?
6. How do you carry the stethoscope and why (around neck, in pocket, etc.)?

Suggestions for Improvement

1. What don't you like about this product?
2. How would you suggest improving this product?

Highlights from User Interviews

1 retired nurse, 1 3rd year of nursing, 1st year med student, 1 trauma surgeon, 1 clinician

Stethoscope selection

• hospitals supply cheaper ones or at a discount
• use cheap ones until you figure out what your environment and specialty was
• problem with diaphragm cracking and drying up

Top Stakeholder Product Needs

Our Top 3 Design Concepts

Design 1: Coat Integration with Heater and Sanitizer

Potential Design Opportunities:

• Integration should not affect the manufacturing of the coat; the design should focus on making mechanisms on the stethoscope that would easily attach to an average doctor's coat.
• Integrating the tubes inside/under the collar - What kind of attachment mechanism...Pins? Velcro? Adhesive? Clips?
• Mounting the heating/sanitizing holder on the chest area of the coat - What kind of attachment mechanism...Safety Pins? Clip? Velcro?

Design 2: Headset Redesign

Design 3: Sitting on our butts

Competitor Products Research
