THE AIM OF THE PROJECT
- Redesign and develop
- Focus on customer-based research
GSK Avamys
Evolution
VoC Research
- Venn diagram
- Identify desirable features of nasal spray from HCP and consumer point of view.
- Overlapping section shows features with greatest significance.
- Indicates which design features to focus on the most.
VoC Research
- Specific consumer research conducted for the Avamys device.
- Overall consumers were highly satisfied with the device.
- Although some areas where consumers were not satisfied and areas which could be improved.
- Examples:
- Mechanism to administer the medicine requires too greater force.
- Smaller and lighter
VoC Research
- Various factors that a HCP would take into account when prescribing a treatment.
- Factors of greatest importance closer to the top.
- Factors of less importance closer to the bottom.
- Significant:
- Familiarity and safety at the top
- Easy of use above cost

We would appreciate any constructive feedback or questions you have.
THANKS FOR LISTENING
- Our design is a slimmed down, light weight evolution of the original.
- Can purchase a single unit and then dispose of cartridges when medicine runs out.
- Intuitive cartridge system for ease of use and visibility of remaining medicine.
- Adapted internal mechanism and improved ergonomics for more comfortable use.
Final Design
Cons
- Bulky
- Complex shape
- Not as portable as other products on market
