Systems analysis phase
of the systems development life cycle (SDLC) involves modeling how the current system works from a logical point of view, identifying weaknesses and opportunities, creating a logical model of the new system, and reviewing the project plan.
Systems analyst
is a technology specialist who understands both technology and business processes.
Systems design phase
of the systems development life cycle (SDLC) involves generating several alternative technical solutions for the new logical model, selecting the best technical alternatives, developing detailed software specifications, and - once again - reviewing the project plan.
Systems implementation phase
of the systems development life cycle (SDLC) involves training users, converting existing information to the new system, converting users, acceptance testing, and reviewing the project plan.

Parallel conversion
is a conversion method in which you run both the old and new system until you're sure the new system works correctly.
Plunge conversion
is a conversion method in which you literally unplug the old system and use the new system exclusively.
Piecemeal conversion
is a conversion method in which you target only a portion of the new system for conversion, ensure that it works correctly, and then convert the remaining system.
