A disadvantage of ________ is that the new system's modules may be tightly integrated, so implementing one without the others may create some confusion and require temporary interfaces to the old systems.
A) phased implementation
B) direct implementation
C) parallel implementation
D) hot standby implementation

Phased implementation involves introducing new modules one at a time, which can lead to confusion and temporary interfaces when implementing new modules without the others. Direct implementation involves switching immediately to the new system, parallel implementation involves running both the old and new systems simultaneously, and hot standby implementation involves maintaining a backup system in case of failure. None of these options would have the same disadvantage as phased implementation.
