Which of the following is a potential risk of selfsourcing?

A、 Reduced technological know-how for future innovation.
B、 Lack of documentation and external support leads to short-lived systems.
C、 Reduced degree of control.
D、 Increased dependency on outside organizations.When end users develop a system, they often forgo documentation of how the system works and fail to realize that they can expect little or no support from IT specialists. All systems—no matter who develops them—must change over time. End users must realize that anticipating those changes is their responsibility and making those changes will be easier if they document their system well.
