For example, the modeling activity defined for the spiral model is accomplished by invoking one or more of the following software engineering actions: prototyping, analysis, and design.The concurrent process model defines a series of events that will trigger transition from state to state for each of the software engineering activities.4 SET-BASED CONCURRENT ENGINEERING MODEL. 150 G V P College of Engineering (Autonomous) 2016 CSEThe concurrent development model, sometimes called concurrent engineering, allows a software team to represent iterative and concurrent elements of any of the process models described in this chapter. (Text Book-1) Semester - V. Specialized Process Models.The Unified Process, Personal and Team Process Models. SOFTWARE ENGINEERING (Common to CSE & IT) Course Code: 15CT1114 L T P C 3003 Pre-requisites: Introduction to computing.The activity modeling may be in any one of the states12 noted at any given time. Figure 1 provides a schematic representation of one software engineering activity within the modeling activity using a concurrent modeling approach. WINWIN Spiral Model, DOD Model, Concurrent Model, NASA Model, Component Based Development Model, Formal Methods Model, Software Integration & Testing. The idea behind it is to ensure that the requirements of all the stakeholders involved in the product development are met.If, however, the customer indicates that changes in requirements must be made, the modeling activity moves from the under development state into the awaiting changes state.Concurrent modeling is applicable to all types of software development and provides an accurate picture of the current state of a project. The modeling activity (which existed in the inactive state while initial communication was completed, now makes a transition into the under development state. All software engineering activities exist concurrently but reside in different states.For example, early in a project the communication activity (not shown in the figure) has completed its first iteration and exists in the awaiting changes state.
Concurrent Model In Software Engineering Software Engineering Actions![]() On the other hand if the speed is too slow then productivity could be affected.Third, software processes should be focused on flexibility and extensibility rather than on high quality. If the evolutions occur too fast, without a period of relaxation, it is certain that the process will fall into chaos. Most project management and estimation techniques are based on linear layouts of activities, so they do not fit completely.Second, evolutionary software processes do not establish the maximum speed of the evolution. The first concern is that prototyping poses a problem to project planning because of the uncertain number of cycles required to construct the product. Glock date codeThe challenge for software teams and their managers is to establish a proper balance between these critical project and product parameters and customer satisfaction (the ultimate arbiter of software quality). The intent of evolutionary models is to develop high-quality software14 in an iterative or incremental manner.However, it is possible to use an evolutionary process to emphasize flexibility, extensibility, and speed of development. And yet, this idea has been proposed by a number of well respected software engineering experts (e.g., , ). Extending the development in order to reach high quality could result in a late delivery of the product, when the opportunity niche has disappeared.This paradigm shift is imposed by the competition on the edge of chaos. Indeed, a software process that focuses on flexibility, extensibility, and speed of development over high quality does sound scary. However, we should prioritize the speed of the development over zero defects.
