While programmers are waiting for feedback, they start the next thing, which leads to multitasking. Eventually, someone re-skins the user interface, and, unless there is some sort of business logic layer in the tool, all checks will fail and you will be left with no easy way to revise the system. In an attempt to just get done, teams revert to human exploration, the automation becomes even more out of date, and, eventually, it will be thrown away.

Test automation eases this burden by automating the tracking and managing of all those testing needs, including how much of the system different tests cover and what other types of testing might be required to cover all the moving parts. In doing so, test automation goes a long way toward helping ensure that teams maintain a high standard of quality at all points along the pipeline. Additionally, it allows testers to focus more time and effort on creating effective test cases to ensure the quality of the software since they’re no longer bogged down in managing all the minutia of testing needs.
Email is a fantastic invention, but it is missing a few key features out of the box. For example: the ability to send emails later, if you don’t get a response. And notifications on which emails are awaiting your reply. Boomerang helps emails flow in and out of your inbox more easily, preventing the dreaded buildup of drafts, unreads and messages you’re “just saving for later” instead of archiving them.

I think we can all agree that automation is a critical part of any organization's software delivery pipeline, especially if you call yourself "agile." It's pretty intuitive that if you automate testing, your release cycles are going to get shorter. "So, if that's the case," you might say, "why don't we just automate everything?" There's a good reason: automation comes with a price.
