无缺点运动(简称ZD),是以完全消除工作缺点为目标的运动。它最初起源于美国。其含义就是使每一位职工都注意并设法为完全消除工作缺点而努力,以较小的费用取得较好的经济效益。其基本理论是抛弃“人总是要犯错误”的前提,换上“不犯错误”的观念。 Impeccable movement (referred to as ZD for short) is a sport aiming at completely eliminating work defects. It originally originated in the United States. Its implication is to make every employee pay attention and try to work hard to completely eliminate work defects and achieve better economic benefits at a relatively small cost. The basic theory is to abandon the premise that “people always make mistakes” and put the idea of ​​“not making mistakes.”
