最佳实践(Best Practice)，是一个管理学概念，认为存在某种技术、方法、过程、活动或机制可以使生产或管理实践的结果达到最优，并减少出错的可能性。

A Best practice is a technique, method, process, activity, incentive, or reward that is believed to be more effective at delivering a particular outcome than any other technique, method, process, etc. when applied to a particular condition or circumstance. The idea is that with proper processes, checks, and testing, a desired outcome can be delivered with fewer problems and unforeseen complications. Best practices can also be defined as the most efficient (least amount of effort) and effective (best results) way of accomplishing a task, based on repeatable procedures that have proven themselves over time for large numbers of people.

A given best practice is only applicable to particular condition or circumstance and may have to be modified or adapted for similar circumstances. In addition, a "best" practice can evolve to become better as improvements are discovered.^[1]

Despite the need to improve on processes as times change and things evolve, best-practice is considered by some as a business buzzword used to describe the process of developing and following a standard way of doing things that multiple organizations can use for management, policy, and especially software systems.

As the term has become more popular, some organizations have begun using the term "best practices" to refer to what are in fact merely 'rules', causing a linguistic drift in which a new term such as "good ideas" is needed to refer to what would previously have been called "best practices."
