Software Development Overview
Let's first understand what software development means. The term consists of two words, software and hardware.
Software is more than just software code. A program is an executable code that performs some computational tasks. Software is considered to be a collection of executable code, related libraries, and documentation. Software, if it is made for a specific requirement, is called a software product.
On the other hand, engineering is the development of products using well-defined scientific principles and methods.

Software engineering is an engineering industry concerned with the development of a software product using well-defined scientific principles, methods, and procedures. The result of software development is an efficient and reliable software product.

This activity includes several stages, which one way or another will have to be faced when developing a fairly large software. This process represents the actions of the customer of development and usually includes such activities as: the formation of requirements and restrictions for the software product.

The contractor analyzes the customer's requirements, performs the design and analysis of the work, decides how the process will proceed on its own, or with the involvement of third-party development teams, it also evaluates and controls the quality of the finished software product and carries out the delivery of the product and the accompanying final activities.

After development, it is necessary to test the system as a whole, thereby confirming its compliance with the customer's requirements   https://www.instinctools.com/cloud-computing/cloud-migration-servic...    When all tests are passed, the software is ready for release. After the release, the developer company is responsible for supporting the software product and releasing new versions that fix bugs and introduce new functionality. It is also necessary to provide support for users of the developed software.

The next key stage in software development is the design stage, that is, modeling the theoretical basis of the future product. The most modern programming tools allow you to partially combine the design and coding stages, that is, the technical implementation of the project being based on an object-oriented approach, but full planning requires more careful and scrupulous modeling.

The key goal of the step-by-step implementation of the developed program is the gradual identification of previously undetected errors and shortcomings in the code. As part of this stage of software development, both the customer and the contractor may encounter a number of rather narrow range of errors associated with partial data mismatch when loading them.
