1 Factors that influence the organization of requirements -nature and scope of the system under development; -Techniques and strategies used to elicit and capture reqts; -Tools and environments employed 2 Organizing by Subsystem Complex systems can only be visualized and built as systems of subsystems; 1st build system-level reqts wo/ref to subsystems; Refine into subsystems/define interfaces; Hierarchy of requirements 3 Organizing by Product Families Common functionality across...

1 What is the goal of software development? "-Develop quality software, -Meet schedule, -Meet budget, -Satisfy customer needs (but customers are varied)" 2 What is the relationship between requirements engineering and project success? "The Standish Group 1994: 1/3 of all projects cancelled and 1/2 overbudget, Reqts errors most common class of error, Reqts errors most expensive errors to fix (multiplicitive effect/rework), Better reqts engr => better project success" 3 S...

P(E) is assumed to be the same for all ___ ______ (Naive Bayes) Naive Bayes Pros - Despite strict independence assumptions, performs surprisingly well for classification on real-world tasks - Natural and incremental learner.
