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.
1. Checklists verify that the necessary minimum gets done. With increasing complexity comes the temptation to skip over the stupid simple stuff and instead focus on the “sexy” parts of one’s work and life. Because the stupid simple stuff is so stupid and simple, we often fool ourselves that it’s not important in the grand scheme of things. But as we’ve seen, it’s often our most basic tasks that can spell the difference between success and disaster.
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.

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.

‘Normal’ checklists are effective whenever there are advantages to standardising performance, time is not critical, the series of tasks is too long to be committed to memory (or there are likely to be interruptions to execution of the task that might interfere with memory retrieval), and the environment enables a physical list to be accessed and used.

In healthcare, this technique is used in resuscitation procedures. Healthcare workers are trained and recertified, in low and high fidelity simulators, to commence procedures such as Advanced Cardiac Life Support without referring to a checklist. When the patient is not readily revived or responding as expected, the team will refer to their checklists or algorithms to make sure the steps have been executed properly, and that they have not forgotten anything. For this reason, healthcare workers often keep a cognitive aid (a ‘checklist’ of sorts) posted on emergency carts, tucked into pockets or loaded onto mobile devices. ‘Boldface’ checklists can be effective whenever there is a critical sequence to be completed but time is short, or the situation does not enable a physical list to be immediately accessed and used.
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.
Healthcare safety activists have looked to checklists to solve a myriad of problems, particularly with the current iteration of checklists that have been imported from aviation. Large-scale implementations with conflicting outcomes suggest that these tools are not as simple or effective as hoped. Scholars debating the efficacy of checklist implementation in healthcare have identified important reasons for varying results: that success requires complex, cultural and organisational change efforts, not just the checklist itself2; that results may be confounded by a mix of the technical and socioadaptive elements,3 and that local contexts may either augment or undermine the implementation's outcomes.4
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.
Whenever he went on business trips, my Dad would always write down the items he would need to take. His checklist would include articles of clothing, types of clothing to take, and personal hygiene items, along with the work-related items he would need. Although I cannot be certain, I strongly suspect he also included lists of work-related issues that he either knew about ahead of time or at the very least he would make a note of to bring up during the trip. That way, he would ensure that nothing would be forgotten by him or left to chance.

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.

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.
