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.
As you can see, the power of checklists is not an illusory phenomenon. A famous surgeon, Atul Gawande, even wrote a book dedicated to this topic. Despite their simplicity, checklists give an extraordinary boost to organizing things in the most effective manner. Though, maybe their very simplicity underlies their power? Anyhow, you should try a few out. That is the only way to realize why you need checklists.
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.
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.
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.

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.
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
 2. Focus only on the “stupid” essential stuff that’s frequently overlooked or skipped. You don’t need a checklist that lists every single step on how to complete a task. That renders a checklist useless. Instead, just focus on putting down the “stupid” but essential stuff that you frequently miss. Your checklist should have no more than 9 items on it. The shorter the better.

IM Checklist program has been created by Kevin Fahey. Kevin Fahey is a very successful internet entrepreneur. He is also a well-known business coach. He had originally created the checklists to guide his students in the course of internet marketing and to educate them with various marketing ideas and strategies. However, recently Kevin Fahey has made up his mind to introduce these checklists for internet marketing strategies to the general public for the sake of educating them to become as successful in this field as he is.
