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.
 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.
Investigators discovered the crash wasn’t caused by a mechanical malfunction, but rather pilot error. The problem was while the new bomber could carry more and fly faster and further than any other bomber in history, it was also an extremely complex plane to operate. To fly it, a pilot had to pay attention to four different engines, retractable landing gear, wing flaps, electric trim tabs, and much, much more. Because the pilot was so preoccupied with all these different systems, he forgot to release a new locking mechanism on the elevator and rudder controls. Overlooking something so simple killed the two men at the helm.
You need sprint planning to ascertain the relevant context of the product and responsibility for certain tasks. The process itself is a kind of endorsement of the decisions taken during the backlog refinement. The checklist's role is to establish a proper context at every point of the backlog. It is a good practice to shape a separate list for three stages of the session - before, after and during the sprint planning.  In doing so, you will reduce the cognitive load of handling practices.
When it comes to checklist implementation, it is important to recognise that aviation checklists are integral to the normal workflow. The aircraft does not stop while the checklist is completed, and the timing of checklist completion is arranged so that it does not conflict with other essential flight activities. To that end, the checklist does not impose an additional burden or workload, but is actually perceived by aircrew as something that makes the flight easier. In contrast, the Time Out is performed before the case can begin, so essentially stands independently of the workflow. To that end, the Time Out is likely to be seen as something additional, and, unless it results in obvious time-saving downstream, will be perceived as an increase in workload. This mixture of purpose between checklist and briefing, in combination with implementation issues, may explain the range of outcomes as well as the range of enthusiastic to skeptical opinions about the mandated use of checklists in surgery.14–16

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

Perhaps, this benefit will be most appreciated by professionals that bear responsibility for other people’s lives as in aviation or medicine. Nevertheless, a disciplined employee is always a catch. With checklists, you have a chance to develop that attractive characteristic. A narrow scope of answers ("yes" and "no") is not a burden to complete. A regular list check instills discipline in those who use it.
Reinforcement and sanctions surrounding tasks may distract performance from the intent of the checklist. In healthcare, there is often a need to adapt the procedure to the patient or the context. Recent findings show that the WHO checklist, for example, is often implemented differently within single organisations, depending on context. Clinicians may be discouraged from acting in a manner that is best for the patient if they perceive that they may be censured for not following the procedure ‘to the letter’.
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.
It is obvious that they spend a lot of time building a strong Internet marketing system to quickly and effectively popularize their business and can gain higher profits. However, this does not mean all of them can handle the field, as the tasks involved intensive knowledge and skills. Therefore,naturally, they will turn to high-profile Internet marketers to solve their troubles.
