The minimum and recommended specifications for the range of XR HMDs are actually not quite straightforward. To really understand it all, you have to think in two dimensions--on both X and Y axes, if you will. Weâre looking at what a range of PC hardware can support, but also what a range of HMD hardware demands.
Lean manufacturing or lean production, often simply  lean , is a systematic method for the elimination of waste ( Muda ) within a manufacturing system.ean principles are derived from the Japanese manufacturing industry. The term was first coined by John Krafcik in his 1988 article, Triumph of the Lean Production System, based on his master's thesis at the MIT Sloan School of Management.

Lean manufacturers donât want employees to work harder, or faster â they want employees to work more efficiently.he difference must then be in how the tools were applied, their appropriateness, but not the tools themselves. 2. Lean is Not Devoid of Technology. The fundamental principle of Lean manufacturing is to design a simple manufacturing system, however, that does not mean eliminating technology.
