Fifty minutes, or ten
A team releases an update by hand. It takes fifty minutes of careful clicking, and once in a while someone makes a mistake.
Another team has a pipeline. The same release takes ten minutes, and nobody clicks anything.
Why would a company want the second way?

The two aims
DevOps has two aims.
- Deliver in an agile way: small steps, regular releases and quick feedback, so the system keeps up with what people need.
- Build, test and release changes: do all three in a smooth, repeatable way, not as a rare scary event.
Five benefits
| Benefit | What it means | Example |
|---|---|---|
| Rapid delivery | New things reach users sooner, helped by automation | A fix goes live in an hour, not a month |
| Increased productivity | People spend time on thinking, not on repeated clicks | A technician writes one script, not forty manual changes |
| Better processes across teams | Developers and operations share steps and goals | One shared checklist for releases |
| Scalability | The system can grow when demand grows | Servers are added by script before a sale |
| Fewer errors | Automatic steps are the same every time | No missed step at 2 am |
