Everything is connected
If a single thread of a spiderweb is touched, then most of it moves.
Not all by the same amount, but the effects can usually be seen elsewhere, too:
sometimes across the whole web.​
​
That's the nature of inter-connected things.​
​Projects behave similarly, especially large and complex infrastructure projects.
If one thing is changed in one part of a project, then it usually doesn't take long for its effects to ripple out in multiple directions, impacting other people working in other parts of the project.
Sometimes these ripple-effects can be seen far, far away,
in areas of the project that would have seemed, at first glance, to be totally unconnected.
Except they're not unconnected, not really:
​
because projects are inter-connected things.​​

Why a Butterfly?

butterfly flaps its wings, 'A
and triggers a tornado half the world away​​​'. ​
​A seemingly
insignificant change
in one place can end
up causing a major
disturbance in another.​​
​​
​​Butterfly effects, Domino effects and Ripple effects:
all are seen in our large and complex infrastructure projects.
