To build a proper testing checklist you need to take into account not only the product requirements and user stories, but also cover a wider spectrum of implementation. At the same time, the test scope should be narrow enough to focus on a product’s functionality. It is also important to make separate tests for different parts or elements of activity. For example, a purchase activity on a website may consist of three parts - signing in, adding products to the cart, and signing out. Splitting your checklists for testing procedures will isolate test failures and keep the focus on the essential details.
Though Gawande admits he didn't expect to see the checklist make much difference in his own surgeries, he followed it to avoid hypocrisy and was surprised by the results. The checklist saved a life in at least one case, where a mistake by Gawande led to a critical need for blood while the mistake was corrected. Thanks to the checklist, extra blood had been prepared ahead of time, despite Gawande's confidence in performing a surgery he'd done successfully many times before.
To-do lists are definitely awesome for getting things done, but there’s another kind of checklist as well – what I call the “routine checklist.” With a routine checklist, you write down all the steps/tasks needed to complete a certain project or process. The list of tasks never changes. You use the same checklist over and over again, every time you do that particular process/project.
Our checklists and checklist templates are licensed for personal use only. However, to avoid a bunch of emails, I will also say that I am okay with you doing almost anything with these checklists except posting the checklist (or anything you have created using the checklist template) on the internet or selling it. That includes permission to print and distribute as many paper copies of your checklist as you need. Don't remove the copyright or hyperlinks that I've included in the spreadsheet, though.
1. Checklists verify that the necessary minimum gets done. With increasing complexity comes the temptation to skip over the stupid simple stuff and instead focus on the “sexy” parts of one’s work and life. Because the stupid simple stuff is so stupid and simple, we often fool ourselves that it’s not important in the grand scheme of things. But as we’ve seen, it’s often our most basic tasks that can spell the difference between success and disaster.
Everything seemed fine, until the patient stopped responding and his heart rate skyrocketed. The patient's blood pressure was barely detectable. Nothing his medical team did improved it, so he was rushed to surgery. Only when he was opened up did the doctor finally realize the stab wound went much further inside the patient than he'd thought, cutting right into the aorta—the main artery from the heart. Although it seemed like a small knife wound, the patient had actually been struck by a bayonet—part of the assailant's costume.
