Special Unicode Characters in Data Validation Lists: ☐, ☑, ✓, ✔ - This may be my favorite approach. You can include special characters like this in a Data Validation drop-down list. This isn't quite as good as clicking once to fill in a checkbox, but it is great for the mobile Excel apps. The only hard part is remembering how to insert a check mark symbol in Excel. For more information, see my article Using Unicode Character Symbols in Excel.
An example from my own work is the process of creating a new blog post. Although I usually remember the steps of creating the content because it's part of my writing process—writing an outline, doing the research, drafting, and editing—there are plenty of other steps that I can easily forget. Adding images, working through multiple headline options to find the best one, and making sure image credits are correct are all standard tasks that are easy to overlook.
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.

That’s it for theory. In practice, you can take advantage of checklists in project management (PM) tools. This sort of software is leveraged to keep the workflow organized and provide the team with the ability to see other stuff circulating in the working environment. However, the market abounds with versatile PM solutions, which is not always a benefit to an inexperienced user. Therefore, you have two paths to choose from - either take a look at a comparison post like this one, or consider the following must-have features in your search:
Pre-flight checklists are a good example. A regular pilot is aware of the importance of checking a list of tasks to prepare an airplane for takeoff. These include checking the operation of the altimeter, fuel gauges, flight controls, magnetos, engine idle, and other system parameters. Besides, preflight checklists are usually segmented in a way that the accomplishment of final items (status of doors/windows, mixture, lights, camera, and action) is completed after the set of initial tasks. The same thing is with the before-landing checklist. According to the FAA's practical test standards, these sets of tasks must be in a written form for pilots’ use.
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.

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.
