By 2050

Futurologists predict that life will probably be very different in 2050.

TV channels will have disappeared. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers, and books will come to us by computer.

Cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Space planes will take people halfway around the world in 2 hours. Today, the United States Space Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just 2 hours.

Robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots—they don’t ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.

Medical technology will have conquered many diseases. Today, there is equipment that connects directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again.

Scientist will have discovered how to control genes（基因）. Scientists have already produced clones(克隆) of animals. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?

阅读以下关于项目整体管理的说明，根据要求回答问题。
[说明]
老陈是系统集成商PQ公司(以下简称为PQ公司)软件开发部的项目经理。5个月前，他被公司派往一览贸易集团有限公司(以下简称为一览公司)现场组织开发办公自动化管理信息系统(以下简称为OA系统)，并担任项目经理。老陈已经领导开发过好几家公司的OA系统，并已形成较为成熟的OA管理软件产品，所以他认为此次应该只要适当地做一些二次开发，并根据用户需求进行少量的新功能开发即可大功告成。
老陈满怀信心地带领他的项目团队进驻了一览公司，老陈和项目团队在技术上已经历过多次考验，他们在3个月的时间就将该OA系统开发完毕，项目很快进入了验收阶段。可是一览公司分管办公事务的吴总认为，一个这么复杂的OA系统在短短的3个月时间里就完成了，这在一览公司的IT项目中还是首次，似乎不太可能。他拒绝在验收书上签字，并要求办公室的叶主任和业务人员认真审核集团公司及其各个子公司的OA管理上的业务需求，严格测试相关系统的功能。
办公室的叶主任与相关人员经过认真审核和测试，发现系统开发基本准确，但实施起来比较困难，因为业务流程变更较大。又1个月过去了，一览公司的吴总认为系统还没有考虑集团公司领导对办公管理的需求，并针对实施较困难的现状，要求项目组从集团公司总部开始，一家一家子公司地逐步推动系统的使用。
老陈答应了一览公司吴总的要求，开始先在集团公司总部实施OA系统。可是1个月过去了，系统却没有安装成功。集团公司信息中心的人员无法顺利地购买服务器，因为这个项目没有列入信息部门的规划。办公室的部分人员也建议：该项目在集团中都推不动，何必再上。老陈一筹莫展，眼看半年过去了，项目似乎没有了终结之日。

结合你的项目管理经验，简要分析产生以上问题的主要原因。
