Which is not the phase of the classical waterfall model?a)Feasibility...
Explanation:
The classical waterfall model is a sequential software development process that follows a linear and rigid approach. It consists of several phases, each building upon the outputs of the previous phase. The phases of the classical waterfall model are:
1. Requirements Gathering: In this phase, the requirements for the software system are identified and documented. It involves gathering information from stakeholders, understanding their needs and expectations, and documenting the functional and non-functional requirements of the software.
2. System Design: In this phase, the overall architecture and design of the software system are created. It involves identifying the system components, their interactions, and the data flow between them. The design is documented in detail, including the data structures, algorithms, and interfaces.
3. Coding: In this phase, the software system is developed by writing the actual code. The design specifications from the previous phase are translated into executable code. It involves writing and testing individual modules or components of the software.
4. Testing: In this phase, the developed software is thoroughly tested to ensure that it meets the specified requirements and functions as expected. It involves executing test cases, identifying and fixing defects, and verifying the correctness and reliability of the software.
5. Deployment: In this phase, the software system is deployed and made available to the end-users. It involves installing the software, configuring it for the target environment, and providing user documentation and support.
6. Maintenance: This phase involves maintaining and supporting the software system after it has been deployed. It includes activities such as bug fixing, enhancements, and updates to address changes in user requirements or the operating environment.
Conclusion:
The correct answer is option D, "None of these". This is because all the phases mentioned in the options (feasibility study, design, and maintenance) are part of the classical waterfall model. The waterfall model is a linear and sequential approach to software development that follows a specific order of phases.
