Pre-flight checklists are a good example. A regular pilot is aware of the importance of checking a list of tasks to prepare an airplane for takeoff. These include checking the operation of the altimeter, fuel gauges, flight controls, magnetos, engine idle, and other system parameters. Besides, preflight checklists are usually segmented in a way that the accomplishment of final items (status of doors/windows, mixture, lights, camera, and action) is completed after the set of initial tasks. The same thing is with the before-landing checklist. According to the FAA's practical test standards, these sets of tasks must be in a written form for pilots’ use.
Special Unicode Characters in Data Validation Lists: ☐, ☑, ✓, ✔ - This may be my favorite approach. You can include special characters like this in a Data Validation drop-down list. This isn't quite as good as clicking once to fill in a checkbox, but it is great for the mobile Excel apps. The only hard part is remembering how to insert a check mark symbol in Excel. For more information, see my article Using Unicode Character Symbols in Excel.
Checklists are an effective way to get things accomplished but they can also create problems. Your success depends on the length of the checklist and your personality. Lists might help one person feel more organized, while others will feel overwhelmed or frustrated. Some people enjoy the tangible aspects of creating a list, while others ignore the list once it is created and focus on their thoughts instead. The key to effectively using a checklist is creating a list method that works for you.

Agile software development leverages a technique called the user story to get enough information for implementing software features from an end-user perspective. Shaping acceptance criteria is an integral part of this process that can be improved with a checklist's help. You can create a special format containing categories, point assessments, labels, names, etc. For example, a Definition of Ready can be transformed in Definition of Done category after changing the story specification. On the picture below, you can see an implementation plan, which is, in fact, a ToDo list containing guidance on how to handle the user story written in the description section.


If you do not want to exhaust your team members’ creativity, checklists are a must-have tool for production. Their function is simple - to check whether anything is forgotten or unfinished. And the most important thing is that you do not have to create a new checklist every time a task appears. Creative energy can be channeled to the more exacting tasks.

We’ve mentioned debugging as a component of the deployment process. However, a process of removing existing and potential errors in the code can be optimized with checklists describing the most important steps for both novice and experienced team members. With that in mind, you will turn the never-ending process of fixing errors into an organized and tailored activity for product optimization.
You might have heard a lot about Internet Marketing especially if you want to start an online venture. But oftentimes, you lack the knowledge on how to start and may get confused about different platforms you want to use to begin your online marketing journey. But a successful marketer, Kevin Fahey has created the IM Checklist, designed to make your marketing easier and more profitable.

Investigators discovered the crash wasn’t caused by a mechanical malfunction, but rather pilot error. The problem was while the new bomber could carry more and fly faster and further than any other bomber in history, it was also an extremely complex plane to operate. To fly it, a pilot had to pay attention to four different engines, retractable landing gear, wing flaps, electric trim tabs, and much, much more. Because the pilot was so preoccupied with all these different systems, he forgot to release a new locking mechanism on the elevator and rudder controls. Overlooking something so simple killed the two men at the helm.
Construction. Take a moment to think about the complexity of building a towering commercial skyscraper. Teams of contractors and subcontractors work on different parts of the building at different times and hundreds of specialists are needed to get the job done: engineers of all kinds, electricians, plumbers, carpenters, elevator installers, excavators, window installers, environmental experts, security experts, geologists, cement pourers, steel manufacturers – the list goes on.
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.
After impressive reductions of catheter-related blood stream infections (CLABSIs) were achieved with the implementation of a checklist bundle, checklists were promoted as evidence medicine should look to this safety solution.19 However, successful reduction of CLABSIs was not due to the checklist alone: multiple interventions addressing ICU safety were implemented at the same time, and it remains unclear what role the checklist specifically played in infection reduction.2 For example, the CLABSI checklist relies on nurse oversight. The changes in nursing behaviour can improve physician performance of line insertion in ways that are unrelated to the checklist: through the ‘Hawthorne’ effect, because the physician knows they are being watched; through empowering nurses and levelling the power gradient between physician and nurse and improving the safety culture; or, through formation of best practice as a habit as physicians insert lines the same way each time.
Billed as a notebook for lists, WorkFlowy is an app to manage all of your checklists. Everything's listed on one sheet, where you'll keep all of your separate lists and sub-lists in order. Select on a bullet-point to focus on a particular sub-list, or the minus button on the left to collapse a list. That makes it easy to organize long checklists and still be able to focus on just the tasks you need to complete right now.
But the military still bought a few Boeings to experiment with. Some test pilots believed the Boeing bomber was a much more effective warplane and got together to figure out how they could get pilots to fly it. Instead of requiring more training, the test pilots implemented a simple pre-flight checklist. It spelled out all the basic tasks that were needed to fly the plane successfully, like checking to see if the battery switches and radio were on before taking off. By implementing the checklist, pilots flew the Boeing bomber 1.8 million miles without a single accident. Thanks to a “stupidly” simple checklist, the Army ended up ordering thirteen thousand Boeing bombers and the B-17 soared into the annals of wartime history.
Modern construction is a perfect example of how checklists can help us manage the complexity of modern life. In today’s complex and interdependent world, failure to communicate is the cause of most of our ineptitude. Different people or teams have different bits of knowledge to complete a project, but failure to communicate that information between the various groups and individuals can cause big-time breakdowns that lead to setbacks, or abject failure.
The crux of this problem is while the world around us is becoming more and more complex, we’re still stuck with a brain that hasn’t changed much in 100,000 years. Sure, we’ve figured out ways to off-load memory storage to books and computers so we can know more; we just haven’t figured out a good way to overcome our evolved biases, cognitive flaws, and intrinsic forgetfulness. And so, despite owning a brain brimming with ever more knowledge, we continue to make stupid mistakes.
B-17 Bombers. You’re likely familiar with the iconic B-17 “Flying Fortress” Bomber. But did you know if it weren’t for a simple checklist, it never would have gained its renown in WWII? In the 1930s, the U.S. Army Air Corps held a competition for airplane manufacturers vying to secure a contract to build the military’s next long-range bomber. Boeing produced a plane that could carry five times as many bombs as the army requested, and flew faster and further than previous bombers. On the day Boeing demonstrated its Flying Fortress, the plane lifted off the tarmac, stalled at 300 feet, and then crashed in a fiery explosion.
Travel checklist. I also have a checklist that I use before I leave on an extended trip. It’s kind of a combo of a to-do list and a routine list. It’s stuff I need to get done, but I use the same list every time. And it’s a DO-CONFIRM checklist: I do my prep from memory but then check the list before I leave to verify that I took care of everything essential. These are the things that I’ve had the most trouble remembering in the past, so they’re on my list:
