Definition of "broad spectrum

When I speak of "broad spectrum", I'm referring to something global, vast and effective in many situations. It's a term we often hear, without always understanding its exact scope. In reality, it expresses an ability to act on a very broad range of elements, be they micro-organisms, IT threats or even currents of ideas.

I find this concept very useful, as it evokes the power of a solution capable of adapting to various environments. But this generality sometimes hides flaws, which we're going to explore together.
