One of the simplest and easiest tools to use in business is a check list. Once you have identified a 'best practice' in your place of work then use of a check list to help people ensure they review / complete key items is a very logical outcome. A common difficulty with checklists is getting people to consistently use them. Building them into other processes (top of a meeting agenda, adding to a standard form etc...) is one of the more effective ways to get people to use them. Of course, there is the importance placed upon checklists by the organisation, but that is a whole other conversation about getting changes to stick!
