経営者の器
Business manager's quality:

小さな企業の経営で成功を収めた経営者が、企業を発展し、その規模が大きくなるにつれ、経営の舵取りがうまくとれなくなてしまい、会社をつぶしてしまうことがある。
There is a possibility that a business manager who has been successful in running a small business will come to be unable to steer the management well, as the company grows and its size gets bigger, and will finally get the company to be bankrupt.

それは、組織が大きくなっていくにつれ、経営者が自分の器を大きくすることができなかったからだ。
It is because the business manager could not have made his quality as a leader large enough for the company's expansion.

（稲盛和夫一日一言から）
