If something of value is in short supply you
will tend to conserve it. That turns out to be true of your capacity to deal
with alternatives, make decisions and even to sustain your efforts at
tasks.These finding have profound implications for enterprise content
management (ECM).
Psychologists have recently described the
phenomenon of
Decision Fatigue. A recent New York Times article
by John Tierney titled,
"Do
You Suffer From Decision Fatigue?" gave an excellent overview which I
will quote extensively here.
The more you make decisions, the less
capacity you have to make additional ones in a given period. And these decisions do not have
to be hard to deplete your capacity — in fact they can be quite trivial. Once
you have depleted that capacity, you generally respond in one of two ways: you
make impulsive decisions or pick the default; or you delay making any
decision.
The biology behind this process is beginning
to be understood. It turns out that making decisions takes energy; in fact
regions of your brain actually use glucose to fuel decision making. If the
glucose becomes depleted it needs to be restored — typically by taking a break
and having a snack. Until that happens, these brain regions, especially those
involved in impulse control, have lowered activity.
However, overall use of glucose by the brain
does not change, because other regions of the brain, including those involved in
seeking reward, become more active.
An increased tendency to make impulsive
decisions is also associated with a reduction in willpower. People become more
easily distracted and less likely to complete tasks, including completing a
series of decisions required of them. Alternatively, they make take the easy way
out by picking a default.
What does this have to do with enterprise
content management? I think it is very important. Let's consider two
examples:
-
Consumer behaviour on a business website —
a web content management (WCM) example
-
Staff execution of work — a business
process management (BPM) example
Website Consumers
One of the studies cited in the New York
Times article compared the degree of decision-making required of online
consumers and the consequences:
"...Kathleen Vohs, ...now at the
University of Minnesota, performed an experiment using the self-service
Web site of Dell Computers. One group in the
experiment carefully studied the advantages and disadvantages of various
features available for a computer — the type of screen, the size of the hard
drive, etc. — without actually making a final decision on which ones to choose.
A second group was given a list of predetermined specifications
and told to configure a computer by going through the laborious, step-by-step
process of locating the specified features among the arrays of options and then
clicking on the right ones. The purpose of this was to duplicate everything that
happens in the postdecisional phase, when the choice is implemented. The
third group had to figure out for themselves which features
they wanted on their computers and go through the process of choosing them; they
didn’t simply ponder options (like the first group) or implement others’ choices
(like the second group). They had to cast the die, and that turned out to be the
most fatiguing task of all. When self-control was measured, they were
the one who were most depleted, by far."
Very clearly then the online purchasing
process required a series of decisions that online consumers found fatiguing,
and which reduced their motivation or self control.
The tiresome nature of the process could
cause some consumers to abandon the website without purchasing
the computer, defeating Dell's aim of selling a computer.
But those consumers who complete the process
became more susceptible to impulse purchases. This is
illustrated in another study:
"Levav... put the experience to use in a
pair of experiments conducted with Mark Heitmann, then at Christian-Albrechts
University in Germany; Andreas Herrmann, at the University of St. Gallen in
Switzerland; and Sheena Iyengar, of Columbia. One involved asking M.B.A.
students in Switzerland to choose a bespoke suit; the other was conducted at
German car dealerships, where customers ordered options for their new sedans.
The car buyers — and these were real customers spending their
own money — had to choose, for instance, among 4 styles of gearshift knobs, 13
kinds of wheel rims, 25 configurations of the engine and gearbox and a palette
of 56 colors for the interior.
As they started picking features, customers would carefully weigh the
choices, but as decision fatigue set in, they would start
settling for whatever the default option was. And the more
tough choices they encountered early in the process — like going through those
56 colors to choose the precise shade of gray or brown — the quicker people
became fatigued and settled for the path of least resistance by taking the
default option. By manipulating the order of the car buyers’ choices, the
researchers found that the customers would end up settling for different kinds
of options, and the average difference totaled more than 1,500 euros per car
(about $2,000 at the time). Whether the customers paid a little extra for fancy
wheel rims or a lot extra for a more powerful engine depended on when
the choice was offered and how much willpower was left in the
customer."
These findings could be used to improve the
effectiveness of a website to help consumers make the best decisions to meet
their needs, or to make the most lucrative, near-term decisions to the benefit
of the vendor.
They also point to the importance of reducing
the number of decisions that are being asked, asking the most important ones
first, and providing default options that ideally are matched to the specific,
expected needs of a given online consumer.
Business Processes
Many business processes are quire automated,
but typically depend on staff to provide input. This input usually takes the
form of decisions, whether those are to interpret handwriting entries on faxes
or to approve a purchase order.
A design goal for most automated business
processes is to process more items while employing fewer staff. Little
consideration is usually given to the decision-making capacities of the staff, or
the consequences of decision fatigue that will lead to poorer or delayed
decisions.
A study of Israeli judges reviewing parole
application cited in the NT Times article illustrate this very clearly:
"Prisoners who appeared early in the
morning received parole about 70 percent of the time, while those who appeared
late in the day were paroled less than 10 percent of the
time."
Those are astounding numbers. The effects of
glucose were clearly illustrated:
"In midmorning, usually a little before
10:30, the parole board would take a break, and the judges would be served a
sandwich and a piece of fruit. The prisoners who appeared just before the break
had only about a 20 percent chance of getting parole, but the ones appearing
right after had around a 65 percent chance."
The safest, default decision for a
judge is clearly to not grant parole. They take the 'easy way out' when decision
fatigued.
Summary
In my
last
post I talked about the 'disjunction effect' and how users may fail to
correctly use the categorizations you designed in your content management
system. In a similar manner, the elucidation of 'decision fatigue' has clear
implications on the potential for success of a wide range of content management
solutions.
