Holmes & Watson pairing
www.mozaicworks.com
Holmes driving: action
“Holmes took his revolver from his drawer 
and slipped it in his pocket.  It was clear 
that he thought that our night's work 
might be a serious one.”
Sherlock Holmes
www.mozaicworks.com
Holmes driving: data
“Data! Data! Data!” he cried impatiently. 
“I can't make bricks without clay.”
“There is nothing more deceptive than an 
obvious fact.”
Sherlock Holmes
www.mozaicworks.com
Watson being a Navigator
“If I irritated him by a certain methodical 
slowness in my mentality, that irritation 
served only to make his own flame­like 
intuitions and impressions flash up the 
more vividly and swiftly”
Dr. Watson
www.mozaicworks.com
Watson navigating: Facts
The navigator remembers facts to the driver
The navigator supports driver's decisions
The navigator needs to see options ahead
Processing data is hard for navigation
www.mozaicworks.com
Holmes & Watson: Learning
“Education never ends, Watson. It is a 
series of lessons, with the greatest for the 
last.”
Sherlock Holmes
"I have not lived for years with Sherlock 
Holmes for nothing."
Dr. Watson
