Netmarble, another game producer, plans to develop a MMORPG (Massive Multiplayer Online Role- Playing Game) to compete with Soft Max. The project manager has identified the activities required to develop the game. The following network diagram represents the initial project plan (numbers in parentheses represent activity duration in weeks). Note that the legend at the top right corner of the network diagram indicates the format used to illustrate earliest start, earliest finish, latest start and latest finish times for each activity, 4 12 1325 ESEF 2539 5 LS 1325 13 LF 25 39 B[8) E(12) H(14) 3945 0 4 4 13 9 20 3945 0 4 4 13 14 | 25 J(6) A(4) C(9) F(11) 24 24 37 4 9 9 6 2639 11 11 26 D(5) G(15) (13) 1 The marketing department believes that releasing the game 2 weeks earlier would be crucial to make the game more competitive and to garner projected market share. The following table lists activities that can be crashed and the associated costs.
