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.
Concerns have recently been fuelled by the disappointing results after implementation of the checklist in Michigan17 and large-scale mandated implementation in Ontario Canada.5 Interpretations of results are also complicated by reported differences between perceived and actual application of the checklist. In a recent US study, hospital documentation indicated 100% compliance with checklists, but observers found that on average only 4 of 13 checklist items were actually completed.18 Even strong advocates for checklists admit that full implementation of the WHO checklist is difficult and that improvements require more than the checklist, including strong institutional leadership, data collection, and monitoring, and training in teamwork.4 ,14
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.
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.
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:

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.

Non-boldface checklists are used to provide decision support when time is not critical. In complicated situations, such as multiple system failures, the checklist appears in the form of a flow chart or decision tree, helping the pilot(s) to navigate the process. In modern aircraft, the checklist is built into the electronic cockpit system, which leads the pilots through the appropriate steps on the screen. The steps are colour-coded for urgency and ranked in priority order. As steps are completed, they disappear from the screen. Checklist items are arranged in a systems operational sequence and are consistent with the patterns of motor and eye movements of the crew.
Sophisticated areas of focus like medicine, software development, numerous sorts of manufacturing, and others abound with complicated pipeline steps. Teams and departments interact to either complement or proceed with the production process in stages that require proper coordination. At first glance, the checklist's role is not remarkable. However, a deeper analysis shows that this tool stores trivial and easy-to-forget tasks outside your brimming-with-tons-of-data brain.

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
‘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.
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.
Checklists are valuable, and you need them if you want to succeed on your digital marketing journey. The checklists have been gathered and experienced by the expert online marketer himself, Kevin Fahey. To know how to start and what to do next, you need these checklists to have better results.

It also eliminates the frustration of forgetting something because you will be following a step-by-step process that can improve your business.

NO, I don’t. I call them “to do” lists. LOL! They’re very helpful, they keep me sane and keep stress away. For many years now, I keep a daily list prepped the night before; and a weekly list that’s prepped every Sunday. Keeps things smooth-sailing all the time. So at the end of the day, if all items are crashed-out (as in “done”!), I feel so good about myself. :)
