For those not aware, Shift Left[1] is (at this point) an old term that was coined for a specific use case, but now refers to a general concept. The concept is that, if you do needed things earlier in a product cycle, it will end up reducing your expense and time in the long run, even if it seems like it's taking longer for you to "get somewhere" earlier on. I think this[2] article is a good no-nonsense explainer for "Why Shift Left?".

So “shift left” is roughly equivalent to “tests first” or “TDD”?

It can also mean manual testing earlier. Valve credits playtesting early and playtesting often for their success with Half-Life, Half-Life 2, and other games.

Not just when they play tested but how. Silently watching someone play, only taking notes. No debrief.

Source: the week I spent in the Valve offices in 2005, having Valve staff playing our in development HL2 mod.

Was it Dystopia, by chance?
