BETTER UNDERSTAND PEOPLE SERVED

7. Understanding needs
The St Mungo’s Broadway team
sought to answer questions such
as:
•What sorts of advice do people
seek before they become
homeless?
•How do St Mungo’s Broadway’s
services perform for different
groups of people?
•What happens to people when
they leave St Mungo’s Broadway’s
services?

DESIGN MORE EFFICIENT PROGRAM

9. Designing more efficient
program
Situation: 3% texters were
superusers using 34% of
counselor’s conversation minutes
(40-50 minutes per conversation)
Result: Identified superusers as
early as their 5th conversation
=> using only 8% of conversation
minutes

BETTER ALLOCATE RESOURCES

11. Better allocate resources
Twitter: @NCD4G DATA SCIENCE FOR SOCIAL GOOD NCData4Good.github.io
Situation: In 2014, there were
more than 20,000 chemical spills
in the US leading to more than 800
deaths and $50 million in property
damage
Challenge: Prioritize facilities to
inspect (~4% of active facilities)
Results: Risk score model to
effectively identify potential
violators, better allocate
inspection resources, and
maximize the impact of each
investigation
