While "How" refers to a system's organization and behavior, "What" refers to a system's goal.
The statement "Once a program is written, our work is finished" is indeed a myth in software development. This misconception can lead to several issues and misunderstandings throughout the development process.
The Waterfall model is not well-suited for accommodating changes once the project has started. This is because the Waterfall model follows a strict sequential approach, where each phase of the software development life cycle is completed before moving on to the next. This lack of flexibility makes it challenging to incorporate changes to requirements, design, or functionality after the project has progressed to later stages.
One of the primary goals of the requirements analysis and specifications phase of the software development life cycle is to understand the customer requirements and organize them into a formal or informal document. This phase is crucial because it sets the foundation for the entire software development process by clarifying what the software needs to achieve and how it should function.
Performance, Design and Functional, and Non-Functional are different kinds of needs, not problems with requirement analysis.
Requirements analysis is widely considered one of the most important phases of the Software Development Life Cycle (SDLC). It sets the foundation for the entire software development process and greatly influences the success of the project.
A prototype is a simplified, often smaller-scale representation of a proposed system. It's created to provide stakeholders, including clients, users, and developers, with a tangible and visual understanding of how the final system will look and function. The primary purpose of creating a prototype is to validate and refine requirements, designs, and functionalities before investing significant time and resources into full-scale development.
The SRS (Software Requirements Specification) document is typically the final outcome of the requirements analysis and specifications phase in software development projects. This document outlines the detailed requirements and specifications for the software being developed. It serves as a formal agreement between the client, stakeholders, and the development team about what the software is expected to accomplish and how it will function.
"Assessment" is not typically considered a named phase in the traditional software development life cycle (SDLC).
They are all non-functional requirements that indicate the system's quality. Functional specifications outline what the software must be able to do.
In most cases, the Software Requirements Specification (SRS) document is written by the system developers or a team of analysts, architects, and developers who are responsible for gathering and documenting the software requirements. These individuals work closely with stakeholders, including clients, users, and business representatives, to understand their needs, expectations, and the scope of the project.
The Waterfall Model is a traditional software development methodology that follows a sequential approach, with each phase of the development process completed before moving on to the next. While the Waterfall Model has its merits, it's not typically chosen when the project development schedule is tight or when there is a need for rapid changes and flexibility. This is because the Waterfall Model's rigid sequential structure can lead to potential challenges when trying to meet tight deadlines or adapting to changing requirements.
The requirements must be specific enough to allow for system design and must be actionable, measurable, testable, tied to identified business needs or prospects.
The Rapid Application Development (RAD) model is a software development methodology that was not specifically proposed by IBM. The RAD model was developed as a response to the traditional waterfall model, aiming to provide a faster and more flexible approach to software development.
"Software is always correct" is not a characteristic of software. In fact, it's important to understand that software, like any complex human-made system, can have errors, defects, and bugs. Software development involves numerous challenges, and ensuring its correctness and reliability is a critical but challenging endeavor.
To optimize performance requirements for identified functions and confirm that synthesized solutions can satisfy client needs, requirements analysis is carried out iteratively in conjunction with functional analysis.
