20世纪80年代中期，由于国际环境的变化，军工企业面临军转民的艰巨任务。某小三线军工厂决定转产气枪，理由很简单，工艺相近，能充分利用原有设备和技术，产品出口国外有销路。第一年出口五万支换回50万美元，员工们非常高兴，认为这是一个正确的决策。决定第二年继续生产，不料国外经销商突然取消定货。产品只有在国销售，每支售价50元人民币。由于售价适中，质量可靠，在本市销路很好。但好景不长，公安部门经常找上门来。由于气枪口径达5.45毫米，有效射程50米，杀伤力巨大，在30米距离能穿透成年人大腿肌肉。不断引发各种刑事案件。最后经市领导决定停产该厂生产的大口径气枪。在这种形势下，该厂只有选择下马。一个国家投资几千万元，有近两千员工的军工厂就这样倒闭了，给国家造成了巨大的损失。该厂的决策为什么失误？具体原因是什么？
