Problem 9-19 (Algorithmic) The product development group at Landon Corporation has been working on a new computer software product that has the potential to capture a large market share. Through outside sources, Landon's management learned that a competitor is working to introduce a similar product. As a result, Landon's top management increased its pressure on the product development group. The group's leader turned to PERT/CPM as an aid to scheduling the activities remaining before the new product can be brought to the market. The project network is as follows: AO 4 4 18 22 D 10 13 3 22 25 22 25 3.1 25 28 Start C 5 10 517 22 Finish G 16 22 619 25 B105 V slo S ELs 16k | 11 5 16 H 16 23 7 | 16 23 Fls 14 | 9 | 14 23 | J | 23 28 5 23 28 The activity time estimates (in weeks) are as follows: Activity Optimistic Most Probable Pessimistic 2.0 4.0 6.0 4.0 4.5 8.0 3.0 5.0 7.0 1.0 3.0 5.0 6.0 11.0 16.0 6.5 8.5 13.5 3.5 6.0 8.5 6.0 14.0 1.0 2.5 7.0 4.0 5.0 6.0 a.
