I was taken with this cartoon and the comments put up by Hugh Macleod last week over at his gapingvoid.com blog so I hope he doesn’t mind me reproducing it here.
Complex isn’t complicated. Complex is just that, complex.
Think about an airplane taking off and landing reliably day after day. Thousands of little processes happening all in sync. Each is simple. Each adds to the complexity of the whole.
Complicated is the other thing, the thing you don’t want. Complicated is difficult. Complicated is separating your business into silos, and then none of those silos talking to each other.
At companies with a toxic culture, even what should be simple can end up complicated. That’s when you know you’ve really got problems…
I like this because it resonates perfectly well with a blog post I put up almost four years ago now called Complex Systems versus Complicated Systems. where I make the point that “whilst complicated systems may be complex (and exhibit emergent properties) it does not follow that complex systems have to be complicated“. A good architecture avoids complicated systems by building them out of lots of simple components whose interactions can certainly create a complex system but not one that needs to be overly complicated.
