A checklist is a type of job aid used to reduce failure by compensating for potential limits of human memory and attention. It helps to ensure consistency and completeness in carrying out a task. A basic example is the "to do list". A more advanced checklist would be a schedule, which lays out tasks to be done according to time of day or other factors. A primary task in checklist is documentation of the task and auditing against the documentation.
- Pre-flight checklists aid in aviation safety to ensure that critical items are not overlooked.
- Used in quality assurance of software engineering, to check process compliance, code standardization and error prevention, and others.
- Often used in industry in operations procedures
- In civil litigation to deal with the complexity of discovery and motions practice. An example is the open-source litigation checklist.
- Can aid in mitigating claims of negligence in public liability claims by providing evidence of a risk management system being in place
- Used by some investors as a critical part of their investment process
- An ornithological checklist (Category:Ornithological checklists), a list of birds with standardized names that helps ornithologists communicate with the public without the use of scientific names in Latin
- A popular tool for tracking sports card collections. Randomly inserted in packs, checklist cards provide information on the contents of sports card set.
- The creation of emergency survival kits
- In professional diving, checklists are used in the preparation of equipment for a dive, and to ensure that the diver and life support systems are fully prepared before they enter the water. To a lesser extent, checklists are used by a minority of recreational divers, and by a larger proportion of technical divers during pre-dive checks. Studies have shown checklists to be effective at reducing the number of errors and consequent incidents.
Health care use
Checklists have been used in healthcare practice to ensure that clinical practice guidelines are followed. An example is the WHO Surgical Safety Checklist developed for the World Health Organization and found to have a large effect on improving patient safety and subsequently found to have a nil effect in a cohort of hospitals in the Province of Ontario in Canada. According to a meta-analysis after introduction of the checklist mortality dropped by 23% and all complications by 40%, higher-quality studies are required to make the meta-analysis more robust. However, checklist use in healthcare has not always met with success and the transferability between settings has been questioned. In the UK, a study on the implementation of a checklist for provision of medical care to elderly patients admitting to hospital found that the checklist highlighted limitations with frailty assessment in acute care and motivated teams to review routine practices, but that work is needed to understand whether and how checklists can be embedded in complex multidisciplinary care.
Other formats are also sometimes used. Aviation checklists generally consist of a system and an action divided by a dashed line, and lack a checkbox as they are often read aloud and are usually intended to be reused.
Excessive dependence of checklists may hinder performance when dealing with a time-critical situation, for example a medical emergency or an in-flight emergency. Checklists should not be used as a replacement for common sense. Intensive training including rote-learning of checklists can help integrate use of checklists with more adaptive and flexible problem solving techniques.
