Product Strategy / UX Research / 2026
Wrist Caddy
A product conceived in 2020 entered a very different market in 2026. I used six years of competitor performance and user evidence to redefine what should be manufactured before my client invested in production.
The Staff-level intervention
The client asked for manufacturing help. I identified a product-definition problem first.
Find a manufacturer for the existing concept.
The design was six years old and the market had matured.
Evaluate market evidence before committing to production.
Manufacturing became the final step rather than the first.
Research approach
Why I used digital ethnography and system analysis
The client was preparing to enter an established product category, but the engagement did not have the budget or access required for recruited clinical interviews or in-field observation. Rather than treat that limitation as a reason to skip discovery, I selected methods that matched the evidence already available in the market.
Digital ethnography
I reviewed naturally occurring conversations, product reviews, and forum discussions from people using comparable phlebotomy products. This allowed me to study unsolicited feedback generated through real use rather than answers prompted by my interview questions.
I looked for repeated problems across products, users, and time, then grouped those signals into themes such as cleanability, retrieval force, tube compatibility, durability, and stability.
System analysis
I mapped the product against the broader blood-draw workflow rather than evaluating the wrist caddy as an isolated object. This helped identify when the product becomes active, what else the clinician is managing at that moment, and where a seemingly minor interaction can increase physical or cognitive load.
The analysis made tube exchange the critical interaction point because the clinician is managing the patient, needle stability, tube sequence, and retrieval simultaneously.
Digital ethnography gave me longitudinal evidence from an already mature market. System analysis gave that evidence context by showing where reported problems intersected with the clinical workflow. Together, the methods helped me move from individual complaints to product requirements and manufacturing questions.
Limitation: forum and review data cannot replace direct observation or prototype testing with clinicians. I treated the findings as discovery evidence and hypotheses to validate before production, not as final clinical proof.
Discover
What I needed to know before recommending manufacturing
Cleanability
Recurring concerns about porous materials and clinical maintenance.
Retrieval
Secure retention could create excessive extraction force.
Compatibility
Different tube sizes produced inconsistent interactions.
Durability
Elastic and fasteners changed after repeated use and cleaning.
Stability
Loaded wearable products could shift or rotate during use.
Attention
The product competes for attention during a demanding procedure.
These were not isolated complaints. They pointed to weaknesses in the interaction model shared by many products in the category.
System analysis
Where the product creates risk in the clinical workflow
The most important usability moment is not wearing the product. It is retrieving a tube while the clinician's attention and motor control are already constrained.
Define
Turning evidence into product decisions
| Evidence | What I concluded | Product decision | Business consequence |
|---|---|---|---|
| Cleaning concerns across porous designs | Material affects clinical usability | Make cleanability a requirement | Do not choose a manufacturer based only on sewing capability |
| Larger tubes can require excessive pull | Retention and retrieval compete | Prototype retention mechanisms | Avoid premature commitment to elastic-loop construction |
| Performance changes over time | First-use testing is insufficient | Add lifecycle testing | Reduce risk of early product failure |
| Tube sizes vary | Universal fit is an assumption | Define supported tube ranges | Create measurable manufacturing specifications |
How I influenced the work
Changed the investment sequence
The founder moved from searching for production capacity to validating product requirements first.
Changed the manufacturing conversation
Manufacturer selection could now be based on functional requirements rather than the original construction alone.
Reduced irreversible risk
Prototype validation became a prerequisite to production commitment.
Outcome
A manufacturing request became a product strategy.
The original idea remains the founder's. My contribution was ensuring that the product entering the 2026 market did not remain frozen in 2020.
