案例四（共计28分）某公司的主要产品是耐久型乙烯壁板，公司的产品销量这几年一直保持稳步增长，但公司的利润却不断下滑，公司决定彻底改变这种状况。第一步就是从供应链的改造开始。公司高薪聘请了一位在供应链管理方面经验丰富的同行业的高管，任命他为主管生产的副总裁，帮助公司提高供应链的效率，降低成本。新来的副总裁率先从采购部入手。采购部采购的物品包括乙烯基本产品、涂料、办公用品、包装材料、集装箱木材、各种设备及维修用的零部件。目前采购部门所有的订单都是手工完成，没有采购系统，使用的一台电脑只是用于文字处理和打印发票。对采购员的考核主要是原材料的价格多少，所以采购员总是想方设法让供应商给予折扣，结果是许多物品的库存量便得分庞大。上星期的检查发现公司的原材料仓库存储了可供使用6个月的瓦楞包装材料，可供使用10个月的涂料和可使用4个月的木材。但是在乙烯基本产品的采购上，生产线时常因为断料而停工。采购经理对此的解释是，他们应该与供应商建立某种关系，但目前这种关系还远没有建立起来。采购经理对部门的人员也有看法，今年新招的几个新人还在熟悉业务，但即便原来的几个采购员在采购的理念和技能上他总感到有所欠缺。请根据上述材料，回答10、11、12、13、14，本题总分28分本案例的企业在采购中存在哪些问题？（4分）
