A best practice may be a technique or methodology that, through experience and research, has proven to reliably cause the desired result. A commitment to using the simplest practices in any field may be a commitment to using all the knowledge and technology at one's disposal to make sure success. The term is employed frequently within the fields of health care, government administration, the education system, project management, hardware and software package development, et al.
A best practice tends to spread throughout a field or industry after a hit has been demonstrated. However, it's often noted that demonstrated best practices are often slow to spread, even within a corporation. consistent with the American Productivity & Quality Center, the three main barriers to adoption of a best practice are a scarcity of data about current best practices, a scarcity of motivation to form changes involved in their adoption, and a scarcity of data and skills required to try to so.
