问答题

RB制造公司是一家位于华中某省的皮鞋制造公司,拥有将近400名工人。大约在一年前,公司失去了两个较大的主顾,因为他们对产品过多的缺陷表示不满。RB公司领导研究了这个问题之后,一致认为:公司的基本工程技术方面还是很可靠的,问题出在生产线上的工人、质量检查员以及管理部门的疏忽大意、缺乏质量管理意识。于是公司决定通过开设一套质量管理课程来解决这个问题。   质量管理课程的授课时间被安排在工作时间之后,每个周五晚上7:00~9:00,历时10周。公司不付给来听课的员工额外的薪水,员工可以自愿听课,但是公司的主管表示,如果一名员工积极的参加培训,那么这个事实将被纪录到他的个人档案里,以后在涉及加薪或提职的问题时,公司将会予以考虑。   课程由质量监控部门的李工程师主讲。主要包括各种讲座,有时还会放映有关质量管理的录像片,并进行一些专题讨论。内容包括质量管理的必要性、影响质量的客观条件、质量检验标准、检验的程序和方法、质量统计方法、抽样检查以及程序控制等内容。公司里所有对此感兴趣的员工,包括监管人员,都可以去听课。   课程刚开始时,听课人数平均60人左右。在课程快要结束时,听课人数已经下降到30人左右。而且,因为课程是安排在周五晚上,所以听课的人都显得心不在焉,有一部分离家远的人员课听到一半就提前回家了。   在总结这一课程培训的时候,人力资源部经理评论说:“李工程师的课讲得不错,内容充实,知识系统,而且他很幽默,使得培训引人入胜,听课人数的减少并不是他的过错。”   请回答下列问题:

您认为这次培训在组织和管理上有哪些不合适的地方
