Software development is the process of designing and implementing a software solution to satisfy a user. The process is more encompassing than programming , writing code , in that it includes conceiving the goal, evaluating feasibility, analyzing requirements , design , testing and release .
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .
The terms programmer and coder overlap software engineer, but they imply only the construction aspect of typical software engineer workload. [5] A software engineer applies a software development process, [1] [6] which involves defining, implementing, testing, managing, and maintaining software systems; creating and modifying the development ...
Software companies aim to deliver a high-quality product on time and under budget. A challenge is that software development effort estimation is often inaccurate. [21] Software development begins by conceiving the project, evaluating its feasibility, analyzing the business requirements, and making a software design.
A software development methodology is a framework that is used to structure, plan, and control the life cycle of a software product. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, agile software development, rapid application development, and extreme programming.
Software architecture is about making fundamental structural choices that are costly to change once implemented. Software architecture choices include specific structural options from possibilities in the design of the software. There are two fundamental laws in software architecture: [3] [4] Everything is a trade-off "Why is more important ...
A software designer may identify a design aspect which has been visited and perhaps even solved by others in the past. A template or pattern describing a solution to a common problem is known as a design pattern. The reuse of such patterns can increase software development velocity. [11]
Many software development processes can be run in a similar way to general project management processes. Examples are: Interpersonal communication and conflict management and resolution. Active, frequent and honest communication is the most important factor in increasing the likelihood of project success and mitigating problematic projects.
