This document contains data from a study measuring the effects of coffee ingestion on motor skills test scores over 4 weeks. In week 1 (no coffee), average scores ranged from 175-218. In week 2 (8oz coffee), scores decreased to 78-174. In week 3 (16oz coffee), scores decreased further to 100-164. In week 4 (no coffee), scores increased again to 170-209, similar to week 1. The data suggests that caffeinated coffee impairs motor skills, though the effects are not permanent. Additional studies are needed to better understand caffeine's effects on other cognitive functions and how tolerance may develop over time on a neurological level.
These slides use concepts from my (Jeff Funk) course on Business Models at National University of Singapore to analyze the business model for Theranos. Theranos provides diagnostic testing for consumers that is faster and cheaper than the existing system. Its tests are done in easy to access pharmacies (e.g., Walgreens) as opposed to hard-to reach doctors’ offices. The tests use small bio-electronic integrated circuits (ICs) instead of large scientific instruments. These ICs utilize micro-fluidic channels that require a pin-prick of blood instead of a vial of blood, which makes the tests more appealing and faster than the traditional tests. The slides describe the value proposition, method of value capture, customers, scope of activities, and method of strategic control for Theranos.

2. TAKE HOME POINTS
1. Past research, including my data suggests that caffeinated
coffee impairs motor skills
2. Do the benefits of caffeinated coffee outweigh its negative
effects?
3. Negative effects were not permanent!
3. ANALYSIS
Additional Studies
- different types of caffeinated
beverages
- how does caffeine effect memory
or other cognitive skills (i.e.
problem solving)?
Limitations/assumption
s
- time of day
(evening/morning)
- improvement through
practice
4. NEW QUESTIONS
How does caffeine effect the brain (i.e.
cerebellum, frontal lobe) on a biochemical
level?
Does building up tolerance to caffeine by
creating more receptors on neurons,
correlate with how the cerebellum and
frontal lobe are affected by caffeine?
