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.
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.
Accepting the fallibility of our memories and the overwhelming amount of information we need to manage and apply in our jobs is an important first step. Realize, as Gawande wrote, that "Knowledge has both saved us and burdened us," and recognize that the checklist can make sure your brain doesn't fail you—ever. Then, you'll be ready to create and rely on a checklist, one that that will help you perform better, and more consistently.
Checklists don't have to be boring. Pocket Lists is a fun, personal checklist iOS that lets you organize your checklists with icons. Organize the things you need to do, then add an icon to each checklist to make it easy to identify. It can manage your daily tasks, with due dates and notifications, and can also keep track of your more detailed checklists to help with your work routines.

Any operation, be it a part of software development process or any other activity, consists of complex and basic tasks. Nobody wants to focus on humdrum stuff instead of the lucrative part of the work. However, both elements are important, and checklists allow you to remember the little things. There happen to be some simple tasks in a pipeline, and they should not be ignored.
Google Sheets beat Microsoft to the punch and introduced a Checkbox as one of the Data Validation options. You can go to Insert > Checkbox to quickly create one, and you can customize it by going to Data > Data Validation. I've updated most of the Google Sheets versions of my checklists to use that feature. I hope Excel gets smart and introduces a similar feature some day.
Boldface items are for immediate action, when the aircraft may be lost if the items are not completed quickly and in the correct order. Correct and rapid execution of these steps is so critical and essential, that pilots must complete them from memory. Through training and repetition, the paired cognitive and motor activities required to perform the checklist are stored by the pilot as procedural memory (or ‘motor skills’).10 Despite notable exceptions (such as ‘choking’ under pressure), procedural memory retrieval is less affected by stress than declarative or episodic memory retrieval.11 For this reason, aircrew practice time critical emergency procedures regularly to aid in forming the correct ‘habits’. However, as soon as time permits, the checklist is used to confirm that the steps were executed as required.8
Many prominent software development companies like Railsware are active users of checklists in their activities and processes. They do not limit their lists to 7 or 10 points. Sometimes, the number of points can stretch up to a couple of pages consisting of subsections for rather complicated processes. And here are some reasons why you should consider using checklists for your needs.

1. Investigate your failures and look for “killer items.” Take a look at your work or even your personal life. Are you less productive at work than you’d like to be? Does the house always seem a disaster? Examine why you aren’t getting the results you want. Look for failure or friction points in the tasks you do routinely. These failure or friction points will serve as the basis for your checklist.
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.

You can leverage checklists in various areas of life. Are you going to get married? There is a wedding checklist. Is a business trip coming up? A travel checklist will help. Other options include inspection, security, packing, invitation, moving, shopping, etc. Most things are like that,  your next or current project will definitely benefit from using this sort of process management tool.


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.
Checklist makes it easy to get started using checklists, with a built-in repository of checklists submitted by users that you can browse and use. You can find lists for almost anything here, from SEO to property inspections to camping. Add the lists you need to your account, or build your own checklists from scratch, and you can get started organizing your workflows without much hassle.
I did my 1st product launch recently, it was a success, but it would of been so much better if I would of had IM Checklist Volume 1 – Product Creation, by my side…I would not of wasted so much time and missed a few key pieces like leaving my buy button live before the actual launch date started!Another great thing about IM Checklists is they come in many different formats…I have been using the Google Sheets version and it has changed the way I do my affiliate promos…Because they are more than just checklists they provide training and insight into things like market research and different marketplaces, also things like how to get approval as an affiliate…This alone would of saved me a lot of time and anguish, when I 1st got started…I could go on and on, oh yeah and they come with PLR rights so I can and do use them for lead magnets and bonuses…Fantastic product, 5 stars for sure…I highly recommend IM Checklists to anyone and everyone that will listen…
In healthcare, we need to get back to the basics with checklists and reserve the tool for processes that are simple, easy to follow, standardised and (perhaps) time critical. Expanding the term to cover briefings and other tools more suited to complex and variable processes is confusing, and may require communication and advanced team skills to implement and sustain. It is appealing to embrace a single tool to improve safety, and checklists have been found to be effective in some settings.16 However, the complexity of quality and safety improvement in healthcare guarantees that solutions will never be singular, straightforward or simple to sustain.
We may not like to admit it, but many of us can describe a time when we’ve made a mistake during the progress of a study. These mistakes can range from mixing up wires or forgetting to turn on an amplifier to forgetting to collect an essential piece of information that either requires additional processing time or prevents you from analyzing a certain variable altogether. Increased computing power and technological advancements have also made it easier than ever to collect data. We can collect five measures simultaneously in one study and hundreds of trials in no time at all. But where does this leave us now? We must set up all of this equipment and make sure it works together, monitor it as well as our participant or specimen, and somehow sift through all the data post hoc. Even with a detailed lab notebook, its no wonder problems can arise. Even just writing this makes me feel…exposed, as if I’m the only one who struggles with this. It seems so simple, how can I not get it perfect every time? I always thought that I just had to work harder to not miss small steps, but maybe I just needed a different, yet structured, perspective on how to manage such a high volume of complex information.
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.
Law school exams. I stumbled upon the power of checklists for managing complex problems while in law school. In a law class, a single three-hour long essay exam determines your final grade. You’re presented with one or two complex hypothetical situations and are required to identify and analyze all the legal issues in them. To excel on law school exams, knowing the law isn’t enough. You have to be adept at applying it to different legal scenarios.

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.
2. Checklists free up mental RAM. People often bristle at using a checklist because it feels constraining. They want to be flexible and creative, and the checklist seems to take away their autonomy. For this reason, implementing checklists among surgeons has proven difficult, even though studies show checklists dramatically reduce the number of preventable, life-threatening errors. Surgeons feel that their work requires an intuitive judgment that’s born from years of training and experience and can’t be reduced to a simple checklist.
Mental checklists to improve thinking. Berkshire Hathaway vice-chairman Charlie Munger uses a mental checklist of biases and cognitive flaws that he reviews before making any big decision to ensure he’s thinking clearly about it. He’ll go down the list and ask himself if any of these biases are clouding his thinking and what he can do to mitigate it. Ever since I’ve learned about that, I’ve tried using something similar in my life. Crafting this list is still a work in progress for me, but here’s what I have so far:
Gawande explains that we are up against two things when performing either a high volume of simple tasks or a variety of complex tasks. The first is that human memory and attention can fail you, especially when a bigger issue arises. This could be your participant being late and your data collection program freezing, making it easy to forget that you haven’t performed a baseline test. The second thing is that we skip tasks even when we remember them because nine times out of ten that step doesn’t matter. Never check to make sure your wires are plugged in correctly?  If you’re the only one working in the lab maybe it doesn’t matter, but if multiple lab mates are cycling through the lab, this could be a bigger issue.
Accepting the fallibility of our memories and the overwhelming amount of information we need to manage and apply in our jobs is an important first step. Realize, as Gawande wrote, that "Knowledge has both saved us and burdened us," and recognize that the checklist can make sure your brain doesn't fail you—ever. Then, you'll be ready to create and rely on a checklist, one that that will help you perform better, and more consistently.

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.
