Several years ago, here at TED, Peter Skillman

3
00:00:18,000 --> 00:00:20,000
introduced a design challenge

4
00:00:20,000 --> 00:00:22,000
called the marshmallow challenge.

5
00:00:22,000 --> 00:00:24,000
And the idea's pretty simple.

6
00:00:24,000 --> 00:00:26,000
Teams of four have to build the tallest free-standing structure

7
00:00:26,000 --> 00:00:28,000
out of 20 sticks of spaghetti,

8
00:00:28,000 --> 00:00:30,000
one yard of tape, one yard of string

9
00:00:30,000 --> 00:00:32,000
and a marshmallow.

10
00:00:32,000 --> 00:00:34,000
The marshmallow has to be on top.

11
00:00:34,000 --> 00:00:37,000
And, though it seems really simple, it's actually pretty hard,

12
00:00:37,000 --> 00:00:39,000
because it forces people

13
00:00:39,000 --> 00:00:41,000
to collaborate very quickly.

14
00:00:41,000 --> 00:00:43,000
And so I thought that this was an interesting idea,

15
00:00:43,000 --> 00:00:46,000
and I incorporated it into a design workshop.

16
00:00:46,000 --> 00:00:48,000
And it was a huge success.

17
00:00:48,000 --> 00:00:50,000
And since then, I've conducted

18
00:00:50,000 --> 00:00:52,000
about 70 design workshops across the world

19
00:00:52,000 --> 00:00:54,000
with students and designers and architects,

20
00:00:54,000 --> 00:00:57,000
even the CTOs of the Fortune 50,

21
00:00:57,000 --> 00:00:59,000
and there's something about this exercise 

22
00:00:59,000 --> 00:01:01,000
that reveals very deep lessons

23
00:01:01,000 --> 00:01:03,000
about the nature of collaboration,

24
00:01:03,000 --> 00:01:05,000
and I'd like to share some of them with you.

25
00:01:05,000 --> 00:01:08,000
So, normally, most people begin

26
00:01:08,000 --> 00:01:11,000
by orienting themselves to the task.

27
00:01:11,000 --> 00:01:14,000
They talk about it, they figure out what it's going to look like,

28
00:01:14,000 --> 00:01:16,000
they jockey for power,

29
00:01:16,000 --> 00:01:18,000
then they spend some time planning, organizing.

30
00:01:18,000 --> 00:01:21,000
They sketch and they lay out spaghetti

31
00:01:21,000 --> 00:01:23,000
They spend the majority of their time

32
00:01:23,000 --> 00:01:26,000
assembling the sticks into ever-growing structures

33
00:01:26,000 --> 00:01:29,000
and then, finally, just as they're running out of time,

34
00:01:29,000 --> 00:01:31,000
someone takes out the marshmallow,

35
00:01:31,000 --> 00:01:34,000
and then they gingerly put it on top,

36
00:01:34,000 --> 00:01:37,000
and then they stand back, and Ta-da!

37
00:01:37,000 --> 00:01:39,000
they admire their work.

38
00:01:39,000 --> 00:01:41,000
But what really happens, most of the time,

39
00:01:41,000 --> 00:01:44,000
is that the "ta-da" turns into an "uh-oh,"

40
00:01:44,000 --> 00:01:46,000
because the weight of the marshmallow causes the entire structure

41
00:01:46,000 --> 00:01:48,000
to buckle and to collapse.

42
00:01:48,000 --> 00:01:50,000
So there are a number of people

43
00:01:50,000 --> 00:01:53,000
who have a lot more "uh-oh" moments than others,

44
00:01:53,000 --> 00:01:56,000
and among the worst are recent graduates of business school.

45
00:01:56,000 --> 00:01:59,000
(Laughter)

46
00:01:59,000 --> 00:02:02,000
They lie, they cheat, they get distracted,

47
00:02:02,000 --> 00:02:04,000
and they produce really lame structures.

48
00:02:04,000 --> 00:02:06,000
And of course there are teams

49
00:02:06,000 --> 00:02:08,000
that have a lot more "ta-da" structures,

50
00:02:08,000 --> 00:02:11,000
and, among the best, are recent graduates of kindergarten.

51
00:02:11,000 --> 00:02:13,000
(Laughter)

52
00:02:13,000 --> 00:02:15,000
And it's pretty amazing.

53
00:02:15,000 --> 00:02:17,000
As Peter tells us,

54
00:02:17,000 --> 00:02:19,000
not only do they produce the tallest structures,

55
00:02:19,000 --> 00:02:22,000
but they're the most interesting structures of them all.

56
00:02:22,000 --> 00:02:24,000
So the question you want to ask is:

57
00:02:24,000 --> 00:02:26,000
How come? Why? What is it about them?

58
00:02:26,000 --> 00:02:28,000
And Peter likes to say that,

59
00:02:28,000 --> 00:02:30,000
"None of the kids spend any time

60
00:02:30,000 --> 00:02:33,000
trying to be CEO of Spaghetti Inc." Right.

61
00:02:33,000 --> 00:02:35,000
They don't spend time jockeying for power.

62
00:02:35,000 --> 00:02:37,000
But there's another reason as well.

63
00:02:37,000 --> 00:02:39,000
And the reason is that business students are trained

64
00:02:39,000 --> 00:02:42,000
to find the single right plan, right.

65
00:02:42,000 --> 00:02:44,000
And then they execute on it.

66
00:02:44,000 --> 00:02:46,000
And then what happens is, when they put the marshmallow on the top,

67
00:02:46,000 --> 00:02:48,000
they run out of time, and what happens?

68
00:02:48,000 --> 00:02:50,000
It's a crisis.

69
00:02:50,000 --> 00:02:53,000
Sound familiar? Right.

70
00:02:53,000 --> 00:02:55,000
What kindergarteners do differently,

71
00:02:55,000 --> 00:02:57,000
is that they start with the marshmallow,

72
00:02:57,000 --> 00:03:00,000
and they build prototypes, successive prototypes,

73
00:03:00,000 --> 00:03:02,000
always keeping the marshmallow on top,

74
00:03:02,000 --> 00:03:05,000
so they have multiple times to fix ill built prototypes along the way.

75
00:03:05,000 --> 00:03:08,000
So designers recognize this type of collaboration

76
00:03:08,000 --> 00:03:11,000
as the essence of the iterative process.

77
00:03:11,000 --> 00:03:13,000
And with each version, kids get instant feedback

78
00:03:13,000 --> 00:03:16,000
about what works and what doesn't work.

79
00:03:16,000 --> 00:03:19,000
So the capacity to play in prototype is really essential,

80
00:03:19,000 --> 00:03:22,000
but let's look at how different teams perform.

81
00:03:22,000 --> 00:03:25,000
So the average for most people is around 20 inches,

82
00:03:25,000 --> 00:03:27,000
business schools students, about half of that,

83
00:03:27,000 --> 00:03:30,000
lawyers, a little better, but not much better than that,

84
00:03:30,000 --> 00:03:32,000
kindergarteners, better than most adults.

85
00:03:32,000 --> 00:03:34,000
Who does the very best?

86
00:03:34,000 --> 00:03:37,000
Architects and engineers, thankfully.

87
00:03:37,000 --> 00:03:42,000
(Laughter)

88
00:03:42,000 --> 00:03:45,000
39 inches is the tallest structure I've seen.

89
00:03:45,000 --> 00:03:48,000
And why is it? Because they understand triangles

90
00:03:48,000 --> 00:03:50,000
and self-re-enforcing geometrical patterns

91
00:03:50,000 --> 00:03:52,000
are the key to building

92
00:03:52,000 --> 00:03:54,000
stable structures.

93
00:03:54,000 --> 00:03:57,000
So CEOs, a little bit better than average.

94
00:03:57,000 --> 00:03:59,000
But here's where it gets interesting.

95
00:03:59,000 --> 00:04:01,000
If you put you put an executive admin. on the team,

96
00:04:01,000 --> 00:04:03,000
they get significantly better.

97
00:04:03,000 --> 00:04:05,000
(Laughter)

98
00:04:06,000 --> 00:04:08,000
It's incredible. You know, you look around, you go, "Oh, that team's going to win."

99
00:04:08,000 --> 00:04:10,000
You can just tell beforehand. And why is that?

100
00:04:10,000 --> 00:04:12,000
Because they have special skills

101
00:04:12,000 --> 00:04:14,000
of facilitation.

102
00:04:14,000 --> 00:04:16,000
They manage the process, they understand the process.

103
00:04:16,000 --> 00:04:18,000
And any team who manages

104
00:04:18,000 --> 00:04:21,000
and pays a close attention to work

105
00:04:21,000 --> 00:04:24,000
will significantly improve the team's performance.

106
00:04:24,000 --> 00:04:27,000
Specialized skills and facilitation skills

107
00:04:27,000 --> 00:04:30,000
are the combination [that] leads to strong success.

108
00:04:30,000 --> 00:04:32,000
If you have 10 teams that typically perform,

109
00:04:32,000 --> 00:04:34,000
you'll get maybe six or so that have standing structures.

110
00:04:34,000 --> 00:04:36,000
And I tried something interesting.

111
00:04:36,000 --> 00:04:39,000
I thought, let's up the ante once.

112
00:04:39,000 --> 00:04:42,000
So I offered a 10,000 dollar prize of software to the winning team.

113
00:04:42,000 --> 00:04:45,000
So what do you think happened to these design students?

114
00:04:45,000 --> 00:04:47,000
What was the result?

115
00:04:48,000 --> 00:04:50,000
Here's what happened.

116
00:04:50,000 --> 00:04:53,000
Not one team had a standing structure.

117
00:04:54,000 --> 00:04:57,000
If anyone had built, say, a one inch structure,

118
00:04:57,000 --> 00:04:59,000
they could have taken home the prize.

119
00:04:59,000 --> 00:05:01,000
So, isn't it interesting that high stakes

120
00:05:01,000 --> 00:05:03,000
have a strong impact.

121
00:05:03,000 --> 00:05:05,000
We did the exercise again with the same students.

122
00:05:05,000 --> 00:05:07,000
What do you think happened then?

123
00:05:07,000 --> 00:05:10,000
So now they understand the value of prototyping.

124
00:05:13,000 --> 00:05:15,000
So the same team went from being the very worst

125
00:05:15,000 --> 00:05:17,000
to being among the very best.

126
00:05:17,000 --> 00:05:20,000
They produced the tallest structures in the least amount of time.

127
00:05:20,000 --> 00:05:22,000
So there's deep lessons for us

128
00:05:22,000 --> 00:05:25,000
about the nature of incentives and success.

129
00:05:25,000 --> 00:05:27,000
So, you might ask: Why would anyone

130
00:05:27,000 --> 00:05:30,000
actually spend time writing a marshmallow challenge?

131
00:05:30,000 --> 00:05:32,000
And the reason is, I help create

132
00:05:32,000 --> 00:05:34,000
digital tools and processes

133
00:05:34,000 --> 00:05:36,000
to help teams build cars and video games

134
00:05:36,000 --> 00:05:38,000
and visual effects.

135
00:05:38,000 --> 00:05:40,000
And what the marshmallow challenge does

136
00:05:40,000 --> 00:05:43,000
is it helps them identify the hidden assumptions.

137
00:05:43,000 --> 00:05:45,000
Because, frankly,

138
00:05:45,000 --> 00:05:48,000
every project has its own marshmallow, doesn't it.

139
00:05:48,000 --> 00:05:50,000
The challenge provides a shared experience,

140
00:05:50,000 --> 00:05:52,000
a common language,

141
00:05:52,000 --> 00:05:54,000
common stance to build the right prototype.

142
00:05:54,000 --> 00:05:56,000
And so, this is the value of the experience,

143
00:05:56,000 --> 00:05:58,000
of this so simple exercise.

144
00:05:58,000 --> 00:06:00,000
And those of you who are interested,

145
00:06:00,000 --> 00:06:02,000
may want to go to marshmallowchallenge.com.

146
00:06:02,000 --> 00:06:04,000
It's a blog that you can look at

147
00:06:04,000 --> 00:06:06,000
how to build the marshmallows.

148
00:06:06,000 --> 00:06:08,000
There's step-by-step instructions on this.

149
00:06:08,000 --> 00:06:11,000
There are crazy examples from around the world

150
00:06:11,000 --> 00:06:13,000
of how people tweak and adjust the system.

151
00:06:13,000 --> 00:06:15,000
There's world records on this as well.

152
00:06:15,000 --> 00:06:17,000
And the fundamental lesson, I believe,

153
00:06:17,000 --> 00:06:19,000
is that design truly is

154
00:06:19,000 --> 00:06:21,000
a contact sport.

155
00:06:21,000 --> 00:06:24,000
It demands that we bring all of our senses to the task,

156
00:06:24,000 --> 00:06:26,000
and that we apply the very best of our thinking,

157
00:06:26,000 --> 00:06:29,000
our feeling and our doing

158
00:06:29,000 --> 00:06:31,000
to the challenge that we have at hand.

159
00:06:31,000 --> 00:06:34,000
And, sometimes, a little prototype of this experience

160
00:06:34,000 --> 00:06:36,000
is all that it takes to turn us

161
00:06:36,000 --> 00:06:38,000
from an "uh-oh" moment to a "ta-da" moment.

162
00:06:38,000 --> 00:06:40,000
And that can make a big difference.

163
00:06:40,000 --> 00:06:42,000
Thank you very much.

164
00:06:42,000 --> 00:06:44,000
(Applause)
