Easiest is Not Simplest

One of the most often perpetuated abuses of language at least by software engineers is equating simplicity with ease. It perversely is often invoked in response to indications that complexity is lurking: identification of inconsistencies and problems down the line are met with a rebuttal along the lines of “let’s just keep it simple for now”, when what is actually meant is “let’s do what is easiest”.

Certainly there is nothing wrong with ease and it is a vital force to rein in issues like scope creep and excessive up front design, but it is crucial to not conflate ease with the far more valueable simplicity. Some of the most difficult to understand systems I’ve worked with seemed to have evolved pretty clearly from a series of steps driven by immediate ease and were chock-full of needless accidental complexity.

Another danger lurking in this area is not distinguishing simple from simplistic. A simple answer does not imply a simple solution. Such a mismatch can be signaled by pursuit of panaceas which may provide answers to some subset of concerns while neglecting or complicating others. Tradeoffs are inevitable and do not imply inferior solutions but they certainly challenge any imputed simplicity.

Perhaps a useful spin is to make sure that the KISS guidance is parsed with proper meaning. _Keep_ing a solution simple is certainly a worthwhile endeavor and which naturally requires tracking any accumulated complexity, which is a very different stance than using the mantra as a shield against deeper thought.

In the words of Steve Jobs:

Simple can be harder than complex: you have to work hard to get your thinking clean to make it simple. But it’s worth it in the end because once you get there, you can move mountains. (1)
