Can someone please enlighten me what the heck an SLA is? I skimmed through the article and felt like he teased at providing a definition several times and then never actually did.
> In IT we have a popular concept which is closely related to these two principles – Service-level agreement (SLA).
It's tired and lame.

> It's tired and lame.
It's an incredibly common term we use at my workplace, and I expect many other engineering orgs use it as well.
We use it not only for services ("five nines"), but also for tasks and human initiated things.
It's a simple and useful stand-in for a complicated and abstract concept. I don't expect to have to explain SLAs every time they are discussed.
