Explain the following characteristics of SRS: Consistent, Traceable, Modifiable c) project involves high technical risk and use of new, unteste 5 echnology. Which process model should be used to manage risk effectively? Explain. d) Explain the Defect Life Cycle. Describe cach stage from defect 5 identification to closure. e) execute Cased on a module contains a set foperation diat ay the hesion type and explain why it is not ide: 1) hat is a Risk Table in software project management? Explain i 5 2 a) Compute the Function Point (FP) value for a software project with the 7 following details: Measurement Parameter Count Low Average High Number of user inputs Number of user outputs 54. Number of external interfaces 4 12 Measurement parameters are equally divided among low, average, nd high complexit Complexity Adjustment Factor (CAF) : 1.1 now will il aftect the final Function Point value?
