Unit II Assessment Question 2 Ramesh Punna Columbia Southern University Original Passage Large-Scale Complex IT Systems (Ian Sommerville, Dave Cliff, Radu Calinescu,Justin Keen, Tim Kelly , Marta Kwiatkowska,John McDermid, and Richard Paige) complexness stems from the number and type of relationships between the trunks components and between the musical arrangement and its environment. If a relatively small number of relationships exist between system components and they change relatively slowly over time, then engineers can fracture deterministic models of the system and stag predictions concerning its properties.However, when the elements in a system learn m all combat-ready relationships, complexity is inevitable. Complex systems are nondeterministic, and system characteristics cannot be predicted by analyzing the systems constituents. Such characteristics emerge when the whole system is put to map and changes over time, depending how it is used and on the state of its exte rnal environment. Dynamic relationships accept those between system elements and the systems environment that change.For example, a assertion relationship is a energetic relationship initially, component A energy not trust component B, so, following well-nigh interchange, A checks that B has performed as expected. Over time, these checks may be reduced in image as As trust in B increases. However, some failure in B may profoundly influence that trust, and, later on the failure, redden more stringent checks might be introduced. Complexity stemming from the dynamic relationships between elements in a system depends on the existence and reputation of these relationships.Engineers cannot analyze this inherent complexity during system development, as it depends on the systems dynamic operating environment. Coalitions of systems in which elements are large software systems are ever inherently complex. The relationships between the elements of the coalition change because they a re not nonparasitic of how the systems are used or of the nature of their operating environments. Consequently, the nonfunctional (often even the functional) behavior of coalitions of systems is emergent and impossible to predict completely.Paraphrase for above passage Minimizing the relationships among the entities in large scale system reduces the complexity. Complex systems are not real scalable and would be huge effort when we need to do any changes over time. Relationships should be changing depending on their performances over the life calendar method of birth control of application to be more robust and granular. Dependency between the software systems must be identified in design phase to make a large scale system and failure to do this surgical process would result in unstable and fragile software system.
