INTRODUCTION

English translation pending.

CORE DEFINITION

The big room, known in lean practice as obeya, is a cross-functional meeting held in a shared physical space whose walls carry the current metrics, blockers, and plans. Participants review the display together and make decisions on the spot. The qualification is that the value comes from information density and cross-functional presence: without live, visible data and decision authority in the room, the format degrades into an ordinary status meeting.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use Blocker Clearance: put the current obstacles on the wall and assign owners in the room. - Use Cross-Team Sync: bring engineering, operations, and suppliers together for rapid joint decisions.

Anchor fast decisions

Written reports and remote threads lose nuance and delay feedback. Co-locating people around a shared visual display raises bandwidth, makes each party's constraints visible to the others, and removes the handoffs that let problems sit unresolved between departments.

Second Law of Thermodynamics

The second law of thermodynamics is one of the four fundamental laws of thermodynamics, stating the irreversibility of thermodynamic processes—isolated systems spontaneously evolve toward thermodynamic equilibrium, the state of maximum entropy. Similarly, a perpetual motion machine of the second kind is impossible. The history of this law can be traced back to Nicolas Carnot's research on the efficiency of heat engines and his Carnot theorem proposed in 1824.

Coherence

In physics, coherence (also called phase coherence) states the possibility of interference between two waves. Two monochromatic beams from the same single light source always interfere with each other. If two wave sources have the same frequency and waveform, they are coherent. The physical sources of coherent waves are not strictly monochromatic; they may be partially coherent. However, beams from different physical sources are mutually incoherent.

The Great Filter

The Great Filter theory is a hypothesis that attempts to explain the Fermi Paradox. It posits that in the development of life, from its early origins to the highest level on the Kardashev scale (Type III, capable of utilizing all resources of its galaxy), there exist certain developmental barriers (referred to as 'filters'). Consequently, extraterrestrial life detectable by humans is extremely rare. The concept was proposed by Robin Hanson: the absence of any extraterrestrial civilizations in the observable universe implies that the emergence of advanced intelligent life is very unlikely. This observation is conceptualized as the 'Great Filter'.
