2. To reduce the code complexity, eliminate the code smells and improve the testability, refactoring is performed by maintenance team. 3. To sustain useful operation of a system in host/target environment by providing requested functional enhancement, repairs, performance improvements and conversions. In a nutshell, Software engineering plays a major role in software development process model in developing systematic, disciplined approach to the development, operation and maintenance of a software.
a) The PMP b) The reliability program plan c) The integrated logistic support plan The purpose of the Software Engineering Management Plan is to develop the policies, procedures and structure in order to foster the support activities and engineering activities required for design and development process of the system. Systems Engineering Management Plan is developed in the conceptual design phase of the life cycle process when the need for the management related requirement arises. SEMP relationship with each of the following: a) The PMP: PMP document will explain about the deliverables, overall tasks with its inputs, approach for performing tasks and its output and schedule required to complete project. The program management plan will serve as the input to SEMP. Based on the information available in PMP, SEMP will be able to prepare a top level plan required for managing systems engineering effort.
Architecture can provide basis of throwaway prototype. Architecture enables a system’s driving quality attributes. Architecture is responsible for defining constraints on subsequent implementation. With the above list of important it shows how and why software architecture is important in carrying out a project Before beginning the designing of a software system, an architects needs to get the key requirement that affect the important structure of the system. The architectural drivers have great influence on the early design decisions the architect makes.
Software risk management concentrates on developing a product with better quality attributes such as security, reliability, performance, .. etc. and the uncertainty associated with the product development. It helps project managers in avoiding unpredicted catastrophic problems. Also, it prevents wrong allocation of resources and taking decisions without proper knowledge or adequate information on anticipated future consequences . To manage software development projects, managers and developers should rely on processes, methods and tools to facilitate assessment, prioritization and mitigation of various risk aspects.
It consists of a comprehensive plan which describes how to maintain, develop, alter and replace or enhance a specific software. The life cycle provides a complete methodology for improvement in the quality of software and the entire development process. Stage 1: Analysis of requirement and planning Requirement analysis is a very important and one of the fundamental stages in SDLC. It is carried out by the senior members of a team with the given inputs from customers, the sales department, domain experts and market surveys in the industry. This information is utilized to plan an approach to initiate the basic project and to conduct a product feasibility study in the various areas such as economical, operational, and technical.
Conclusion We can conclude that any software project needs to be executed with a formally defined process. The increased complexities and huge size of the software development projects make them tough to control without formal practices. If the software development process is weak the end product will undoubtedly suffer. Therefore the selection of the right process model is essential in developing a successful product. Also these formally defined development processes are likely to reduce the post-development costs due to early recognition of errors.
Devising a data conversion strategy and a changeover for TIMS must include the design plan, post-implementation appraisal, fact assembly, topics to cover, and who should accomplish it. Integration Integration testing comes before system testing and after unit testing has been completed. The integration testing stage will make developers aware of any errors produced due to the system or the script. The integration testing phase seeks to confirm that the integration of the components is fruitful and that it runs effectively, devise a test plan, and collect test case data produced to efficiently test that the integration is efficacious. Integration Test Plan When creating a test plan it must include the following information, Testing modules and how the tests will be accompanied.
Project management has been firmly established as a concept for organizing, innovative as well as strategic endeavors. Software development organization follows some process when developing a software product. A key component of any software development process is the software development methodology on which the process is based. The particular methodology can significantly affect overall life cycle cost associated with a software product. The selection of the methodology is also based on the some predefined basic characteristics of the product under design.
Engineering software development, requirements analysis, which includes a new product, or modified to meet the needs or circumstances and, as such, potentially conflicting needs of various stakeholders in beneficiary accounts or users. Needs analysis is critical for successful project development. For the purposes of the case, age is verified, related to identified business needs and opportunities and design can be defined as a sufficient level of detail. Can work nonfunctional requirements. The purpose of the needs analysis phase begins when the subject long ago.
Whenever there are any features modified to improve the software quality then there arises a change in the existing software architecture. The process of Software Architecture Recovery (SAR): The process of Software Architecture must be accompanied with two main approaches. They
