2.1 A system is an organized way of achieving a goal without any consideration of the people involved.
2.2 A critical path refers to a sequence of activities whose order and durations gave no direct impact on meeting a projects completion deadline.
2.3 The feasibility committee is responsible for devising a plan to implement both the new computer hardware and the proposed system.
2.4 Once a new system is completed, no following valuation of its performance is undertaken.
2.5 The limits check is a procedural control.
2.6 Greater risk is associated with direct conversion than with phased conversion.
2.7 The post-implementation valuation is normally conducted 1 year after system implementation.
2.8 The success of an software project depends entirely on its quality as viewed by users.
2.9 CASE are software tools that give automated support for a few portion of the systems development process.
2.10 A parallel run involves the concurrent operation of the existing system and the new system.
