6. Saving lives: Checklists can literally save lives. When the U.S. Army Air Corps introduced the B-17 bomber during WWII an experienced aviator crashed the plane during its second demonstration flight. After this tragedy the Army required that pilots use a checklist before taking off. This is the same type of checklist we see pilots use today that helps to avoid crashes.
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.
‘Non-boldface’ checklists form part of the normal framework of ‘job aids’, which might also include mnemonics and other rote learning tools, task visibility, context-sensitive help functions, decision support and instruction manuals. Mnemonics (such as ‘ABC’ for ‘Airway, Breathing, Circulation’ in resuscitation), for example, are sometimes used to retrieve procedural items where participants are likely to be subject to high cognitive load; however, mnemonics are more critical in situations where there is no later access to a physical checklist for confirmation.
It's primarally a to-do list app, but Wunderlist can also be a great tool to create checklists. It's free, runs on just about every device, and is incredibly simple to use. You can't duplicate lists, but you can make a list and share it a Public List. Anyone—on your team or around the globe—can then add the list to their account, check off the items, then add it again whenever needed. It's a workaround, one that might keep you from needing a new app just for making checklists.
Second, the roles of the team members in completing the checklist are not clear. Who will read the checklist? Who will verify that the actions have been completed? Each clinician's role in the checklist should be formalised for the surgical setting, so that when tempo is high, steps are not missed. Third, compliance requires that boxes be ticked. This means that at least one team member will be occupied with completing the checklist and thereby not be available for other tasks. Boxes are more suited to a shopping list format, where items must be completed but order is unimportant, rather than an aviation-style checklist. Problems arising from combining a memory support tool with an audit device are discussed below.
3. Checklists instill discipline. Checklists continue to play a vital role in aviation. Every time pilots and co-pilots take off and land, they verbally go through a checklist. A lot of what they review is of course the stupid simple stuff, but it’s important stupid simple stuff. When you’re responsible for the lives of 120 passengers, you have to have the discipline to make sure you do even the small things right. If there’s ever an incident in air, investigators will go back to see if the pilot and co-pilot went through the checklist. There’s no fudging with it. You either did it or you didn’t.

Every construction job begins with a massive checklist of tasks that have to get done and each task has an accompanying deadline. While that to-do list plays an important role in ensuring stuff gets done, an equally valuable checklist is also used. Called a “submittal schedule,” it centers on communication. The submittal schedule details which project managers need to talk to which project managers during a specific phase and about a specific process. The submittal schedule’s purpose is to get teams that are working on different yet co-dependent projects to regularly connect so they can discuss any potential sticking points. For example, there might be an item on the checklist for carpenters and plumbers to meet up at a specific time to discuss their progress on their respective tasks. Maybe a problem has come up with the pipes that affects when the carpenters can get started on their work, but perhaps there’s something the carpenters can do to help the plumbers. The trick is to keep each other in the loop so each respective team can take care of these “known unknowns” as quickly and as effectively as they can. Once the teams talk, they check the communication task as complete, and move on with their work.


Clinicians have long relied on an analogous form of decision support such as lists or algorithms for differential diagnosis. When a patient presentation is unusual (non-normal but not emergent), differential diagnosis lists (whether in old-fashioned textbooks or new-fashioned handhelds) support clinical performance by serving as a cognitive aid. The practice of reviewing a complete differential helps overcome anchoring and confirmation biases and can be a forcing function to ensure that every critical, and treatable aetiology is ‘ruled out’. Unlike non-normal checklists that are built into cockpit workflow, differential lists are often not well-integrated into clinical workflow and this may undermine their use.12
It is obvious that one can use a screwdriver as a hammer, but that won’t be efficient. It’s similar with leveraging Git. To make the most of it, you need a recipe to achieve the highest productivity. It is all possible with Git workflows. Besides, a consistent Git workflow ensures more chances to free your development pipeline of unnecessary obstacles. In that case, a checklist is a solution to avoid committing to memory every component of your software development cycle. The tool is able to guide anyone through the workflow jungles including user stories issues, solution coding, forking the code repository, and others.
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.
This week I made my first checklist for setting up one of my thesis data collections. I listed specific essential tasks and supplemented them with common errors I had either made or had encountered in the past. After making this specific checklist, I decided to see if I could make a general list that could be applied to all studies. Surprisingly, it was easier to do than I thought, although I’m sure it isn’t perfect. I was able to group many of my tasks together under one common point. What is not easy so far is trusting and not deviating from the checklist. It’s been easy to throw the checklist to the side when I get frustrated. In more stressful situations or even when things are running smoothly, I may forget that I’ve come up with a structured way to make sure I’m managing my data collection in the best way possible.
