To run the old system and the new system at the same time for a specified period, the system implementation approach used is A. pilot B. phased C. parallel D. direct E. None of the above

pilot
phased
parallel
direct E. None of the above

The correct answer is C. Parallel.

In a parallel system implementation approach, the old system and the new system are run at the same time for a specified period. This allows users to compare the two systems and make sure that the new system meets their needs before the old system is retired.

The other options are incorrect because they do not involve running the old system and the new system at the same time.

  • A pilot system implementation approach involves testing the new system with a small group of users before rolling it out to the entire organization.
  • A phased system implementation approach involves rolling out the new system in phases, with each phase involving a different group of users.
  • A direct system implementation approach involves replacing the old system with the new system all at once.

I hope this helps!
