Describe the differences between a software analysis model and the Essay

Describe the differences between a parcel product musical arrangement analysis stupefy and the instauration model - Essay ExampleAfter the project pass the feasibleness study, the estimation of cost, time and efforts is done. Incorrect estimation of these resources may lead to cost overruns and might prove bootleg to the project. The result of the software analysis model is a detailed SRS (Software Requirement Specification) document describing of the systems functionality as per the customers requirements. This document would define the system and serves as the base for rest of the processes in the software development life cycle (SDLC). Software digit model aims to design the conceptual model of the system, which defines various processes involved in the system and also the data used at each process. The software design can be expressed using various diagrams including activity diagrams, sequence diagrams, collaboration diagrams etc. They represent the flow of information as well as the entities involved within the system, based upon which the literal implementation and coding of the software is done. One of the important models for software design is object-oriented design model, in which we come in various objects that occur in the solution domain and the relationship between these objects. After this, detailed design of the object model is done. Other important software design models are prototyping and spiral lifecycle models. ... Reliability of software is of utmost importance towards implementing critical applications, for simulation the software used in aerospace systems. Reliability of the software also increases its availability for each additional development. Also, software reliability enhances customer satisfaction, thus, resulting in the low maintenance demands of the system. other important characteristic of reliable software is that it effectively handles wrong input from the user and prevent from every system failure as a result of the wrong input. Further, reliable software continuously monitors any defects or faults in the system and quickly report/detect these faults. Reusability A good software design should make the components of software development as reusable. Reusability of software objects discredits the development time and also increases programmers productivity and the software quality. However, dependencies of software components on the other parts of the software reduce its reusability, and thus reduce the number of contexts in which these components can be invoked in. Also, software reusability depends on the programmers understanding of the system and his capability to utilize the components to make a better and an efficient system. Another one of the major advantages of reusability is the trim back development costs and faster software deployment. However, there are issues related to software reuse for example lack of organizational support to institutionalize software reuse, intellectu al property rights and contractual problems of software reuse Flexibility We may require changing certain features of the existing software in terms of adding more than functionality
