Amoeba is a kind of amoeba, which lives mostly in water and belongs to Carnipoda. Amoeba protozoa are mostly mononuclear organisms with soft and transparent bodies, which can give birth to amorphous "pseudopods". The shape and outline of their bodies will change with the expansion and contraction of pseudopods, and most of them are parasitic, so their vitality is extremely tenacious.

Kazuo inamori's "amoeba management" is a way of running a company. It regards the whole company as the largest amoeba unit, and each business unit (SBU) of the company is a smaller amoeba unit, and then it is further subdivided within the business unit to get a smaller amoeba unit, namely the micro-enterprise business unit (Ming -SBU), and then it is subdivided into a smaller amoeba unit, namely the cell -SBU. These subdivided business units make their own plans, and based on the plans, realize "quantitative decentralization", let every employee participate in the operation and become the operator of the enterprise, cooperate with independent accounting, let each business unit grow independently, improve the execution of the team, and finally realize the business objectives of the enterprise.
