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 .
Software engineering is a field within computer science focused on designing, developing, testing, and maintaining of software applications.It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
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.
A software engineer usually is responsible for the same tasks as a developer plus broader responsibilities of software engineering including architecting and designing new features and applications, targeting new platforms, managing the software development lifecycle (design, implementation, testing, and deployment), leading a team of ...
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.
The industry also includes software services, such as training, documentation, consulting and data recovery. The software and computer services industry spends more than 11% of its net sales for Research & Development which is in comparison with other industries the second highest share after pharmaceuticals & biotechnology.

The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system).It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public.
Software construction is a software engineering discipline. It is the detailed creation of working meaningful software through a combination of coding, verification, unit testing, integration testing, and debugging. It is linked to all the other software engineering disciplines, most strongly to software design and software testing. [1]
