Chapter 2 - INCOSE CSEP Test Prep Questions With 100% Correct Answers.

Definition of Systems Engineering - Systems Engineering (SE) is an interdisciplinary approach and means to enable the realization of successful systems. It focuses on defining customer needs and required functionality early in the development cycle, documenting requirements, and then proceeding with design synthesis and system validation while considering the complete problem: operations, cost and schedule, performance, training and support, test, manufacturing, and disposal. SE considers both the business and the technical needs of all customers with the goal of providing a quality product that meets the user needs. Variance in cost overruns ________ with increasing SE effort - Lessons 2.7 with low SE effort, projects having difficulty predicting cost overruns from _____% - ______% - 0% - 200% Schedule overruns lesson with _____SE effort, minimizing at about _____% effort - increasing, 10% 2.7 with _____% SE effort cost is predictable from -20% - ____% - 12%, 41% With low SE effort, projects having difficulty predicting schedule overruns from ____% - ____% - - 35%, 300% 2.7 Schedule variance overruns _____with increasing SE effort - lessons 2.7 Primary goal of systems engineering - reduce risk associated with new systems or modifications to complex systems. 2.6The systems engineer's job is to... - Control interfaces between system elements and external systems. 2.5 Challenges in the development of a system - -system elements operate independently -System elements have different life cycles -initial reqmnts likely ambiguous -complexity is a major issue -management can over shadow engineering -fuzzy boundaries cause confusion -SOS engineering is never finished Why use SE - -reduce risk -manage complexity -manage change -projects that are 20% complete already locked in 80% of TLCC -Market penetration has reduced by a factor of 4 over the last 50 years 2.6 Cost over runs _____ with Increasing SE effort at about ___% SE effort - lessens, 10%
