Wikipedia defines:

• 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 the environment changes, 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."

So lets apply the concept of best practices to best practices management. Although we could spends pages defining best practices management for different functions, we will focus on overall concept of best practices management rather than functional best practices management.  Although best practices management include Leadership. Honesty, and Respect plus many others we will further refine our discussion to best practices management as it relates to understanding and improving an organizations processes.

Business Process Management focuses on:

•  understanding and improving cross functional processes.
• documenting your processes
• updating your process documentation on an appropriate time frame or when the process changes
• having process managers and owners who are responsible and have authority for entire process across departments
• reporting cross functional process results to senior management
• continuously improving cross functional processes
• training employees and executives on importance and techniques of process management
