Why do IS fails? Well there are a lot of factors causing this and in think the biggest factor is poor planning and strategy error, this will cause problems such as missed deadlines, unmet requirements, dissatisfied customers, excessive costs, and unused systems. And sometimes it leads to resource management problems because of unforeseen problems the system will encounter. I think there is no such thing as a bad strategy, because we usually weigh pros and cons and eventually choose the one with lesser cons, the problem is some cons greatly affect the company like changing company systems which leads to inability to adapt to the system. Also choosing fast, less cost, less efficient short-term over slow, costly, but efficient and long-term solutions results to recurring problems like what we've discussed on class. Lack and or faulty IT infrastructure (hardware, software, network, etc.), Having these technical problems slows down the transactions, causes miscommunication, inflates company expenses and cripples the efficiency of the system. Having insufficient numbers of adequately skilled IT staff will cause problems such as inaccurate data and software/hardware problems. How could a system run smoothly without a competent and skilled staff?
