This document discusses email overload and its costs. It summarizes existing research which shows that information overload costs the US economy $997 billion annually, and costs Intel nearly $1 billion per year in lost productivity. The main cause of email overload is identified as the number of unresolved tasks in a user's inbox, rather than message volume. Common coping techniques are discussed along with their drawbacks. The document also outlines some technical and behavioral solutions that have been proposed by researchers to address email overload.

problem cost the U.S. economy around $997
billion in 2010.”

Management, 21(5), 32.
4. “But one calculation by Nathan Zeldes and two other
researchers put Intel’s annual cost of reduced efficiency, in the
form of time lost to handling unnecessary e-mail and
recovering from information interruptions, at nearly $1 billion.”

6. “A study by Microsoft researchers tracking the e-mail habits of
coworkers found that once their work had been interrupted by
an e-mail notification, people took, on average, 24 minutes to
return to the suspended task.”

Review, 87(9), 83–89. Harvard Business School Publication Corp.
7. “Stressed IT professionals are linked to issues of organizational
commitment, turnover intentions, and work exhaustion.”
“Two recent studies have emphasized the importance of technostress by studying
the impacts of technostress. These studies have found that individuals experiencing
technostress have lower productivity and job satisfaction, and decreased
commitment to the organization.”

Antecedents and Implications. MIS Quarterly, 35(4), 831-858.
13. It’s a big issue to a lot of people!
Wrote a quick post (rebuttal) and put it on Hacker News:
―Email is not broken, we are.‖
Got up to #3 position within an hour, generated 30
comments and 53 points (as of now)
50/50 on the positive/negative tone of the comment

16. Existing Research
Information overload proposed as idea in
1970’s, research began in earnest in the late 80’s, early
90’s.
Email overload research began in mid-90’s.
Split across psychological and HCI barriers, little
treatment in the management sciences.
17. Existing Research
Influential researchers with an email overload focus:
Nicolas Duchenaut (Xerox PARC)
Victoria Bellotti (Xerox PARC)
Heavily
Steve Whittaker (University of Sheffield)
Danyel Fisher (Microsoft Research) practitioner
Eric Horvitz (Microsoft Research) driven
Bernard Kerr (IBM Research)
18. Email = Tasks ≠ Communication
Email is now about tasks
Multiple researchers have found that email has morphed
beyond long-form communication into a task center.
The more involved the task the higher the overload
“However, neither rapid-response nor extended-response tasks
are, we believe, the source of the biggest headache in
managing “e-mail overload” (as defined in Whittaker and
Sidner, 1996). We believe that a significant source of
overloading is an overlooked factor that we call
interdependent task management”
(Bellotti et al., 2005).
19. The Overall Cause of Email Overload
“Bellotti et al., examining email as a center for
tasks, found that users’ perceptions of
overload corresponds to the number of
unresolved tasks in the users’ inbox (and not
the volume of messages incoming).”
- Hogan and Fisher, 2006
20. Common Coping Techniques
Filing for organization
“Action” folders for specific items
Massive folder structures for recall
Attention Manipulation
Marking read messages as unread
Resending messages to oneself to remember them
Forwarding to others
21. Bad Behaviors
Not communicating interaction expectations (social
contract)
Multicasting (CC spam, for every 100 people CC’ed, the
org loses 8 hours of working time)
Over-delegation resulting from the ―cheapness‖ of email
Constant email checking means you never achieve full
productivity
Most of the common coping methods mentioned on the
previous slide

23. Productivity vs. Acceleration
In a nutshell, current thinking and practice has confused
productivity with doing more faster, or acceleration.
―Time out is a punishment because of our focus on
productivity as a society.‖ – David Levy
―In this post-industrialist society, we don’t have a very
good definition of productivity.‖ – Jonathan Spira
Only 5% of a knowledge worker’s day is available for
reflection and deep thinking
24. Technostress
A real physical problem causing increased stress, decreased
health, poor productivity and job satisfaction, family life
conflicts, and increased turnover likelihood.
Most likely caused by fragmentation of work
―In an information economy, attention is a scarce resource‖
(Ayyagari et al., 2011). Scattering attention squanders both our
competitive advantage as well as our wellbeing.
Executives deal with ~300 messages a day, with 40 requiring
quality, complex decisions—
too many (Zeldes, 2010).
31. Tech solutions have been tried, but few
have stuck or been implemented.
WHY? SOLUTIONS
Incomplete Only build small tools that
implementations (ie, you can integrate with existing
can’t replace Outlook) clients and solutions
Lack of actionable data We need an email
anonymizer for research
40. Re-establish the Social Contract!
Decide on your email checking and response
habits, both personally and as a team.
Write down these expectations as a charter
or as a contract, publish for the team.
Define what will happen when people need
faster responses, be aware of the habits of
others.
41. Tips: Do these NOW!
1. Turn off desktop alerts in your
email client
2. Put your receiving on a
schedule, block out email
times during your day
47. Future Research
We need more usable/minable data. Create an email collection
system that sits at the server level and collects anonymized
data to create a corpus for researchers.
Knowledge management science to replace our existing and
unfitting industrialist management science
Productivity vs. Acceleration
Attention self-manipulation: what and why do people
repurpose tools to deal with perceived overload? Do they
realize the harmful effects?
