true or false with error correction 35. PERT is an acronym for Project Expert and Resource Technique. 36. The purpose of PERT is to coordinate the activities in a project, such as a systems implementation project. 37. One thing that can go wrong during systems implementation is implementing a system that has not been completely tested. 38. A PERT network diagram reflects the logical sequence of systems implementation activities. 39. The slack time for a PERT activity represents the amount of time the activity can be delayed without delaying the entire project. 40. The critical path represents the most time-consuming path through a PERT network diagram. 41. Gantt charts are the same as PERT charts. 42. Project management software allows users to perform what-if analysis?for example, to determine how different work schedules might lower the time to install a new computer system. 43. Controls are rarely established during the implementation of a new computer systemthis must wait for the first audit of the system. 44. During systems implementation, converting computer files is only necessary if the files are currently in manual formats. 45. A turnkey computer system is a complete set of computer hardware and software that allows the user to avoid technical decisions and to begin operating quickly. 46. Parallel conversion and direct conversion methods for testing a new system are quite similar. 47. As part of the systems follow up work, an implementation team can watch employees perform their work activities to ascertain whether the employees are executing their assigned job functions correctly. 48. At the conclusion of the initial follow-up study, a project leader will prepare a report called a post-implementation review report. 49. The tasks involved in systems maintenance are normally performed by external vendors, and rarely by a companys internal information systems department. 50. When using outsourcing, a company needing data processing services hires an outside organization to handle all or part of these services. 51. A possible advantage of outsourcing is that it frees corporate assets for other projects. 52. Outsourcing can help a company avoid seasonal fluctuations in its business. 53. Outsourcing facilitates downsizing. 54. A disadvantage of outsourcing is that a company can lose control of its IT systems and data processing
