1.
An invented term by corporate management to describe one person's solution to a work task or process as 'revolutionary' or so unique that one is required to share this 'practice' with others at work.

The politically correct and corporate accepted term used to require folks to gather together in a time wasting meeting so the expenditures can be justified to senior management.

2.
A phrase primarily used by technologists or tech companies to describe what it is that they alone do and recommend. Contrary to its seeming meaning, "best practices" are ill-defined and constantly changing, even within a single organization.
"This presentation will provide you with best practices, as defined by me and, probably, Malcom Gladwell."
