Complicated (many dependencies, but are linear and predictable) is different from complex (many unpredictable interdependencies).

When we approach complicated problems, we can take everything apart, understand how doing x will lead to y, and make a carefully considered plan of how to reach a solution.

By contrast, when faced with complex problems, there are not any certainties, only likelihoods – if I do x, this may lead to y, but unknown factors a b c may also influence the outcome.

So apart from spending time on understanding what is likely to get us closer to the solution, perhaps what is more important is practising and developing the skills of resilience, flexibility, and adaptability.
