The software itself is a series of instructions or programs that tell a computer what to do. It is hardware independent and makes computers programmable.

There are three basic types:

  1. System software to provide essential functions such as operating systems, hard drive management, utilities, hardware management and other operational requirements.
  2. Programming software that provides programmers with tools such as text editors, compilers, linkers, debuggers, and other code creation tools.
  3. Application software (applications or applications) to assist users in performing tasks. Examples are office productivity suites, data management software, media players, and security programs. The apps also refer to web and mobile apps, such as those used to shop on Amazon.com, get to know Facebook, or post photos on Instagram.

A fourth possible type is embedded software. Integrated systems software is used to control machines and devices that are not normally considered computers – telecommunications networks, automobiles, industrial robots and more. These devices and their software can be connected through the Internet of Things (IoT).

Software development is mainly done by programmers, software developers and software developers. These roles interact and overlap, and the dynamics between them varies considerably between development departments and communities.

Software developers apply technical principles to create software and systems to solve problems. They use modelling language and other tools to develop solutions that can often be applied to problems in general, rather than just for a specific instance or client.

Software developers play a less formal role than engineers and can be tightly integrated into certain project areas – including writing code. At the same time, they control the entire software development lifecycle – including the work between functional teams to convert requirements to functions, manage development teams and processes, and perform testing and maintenance of software.

Software development work is not limited to programmers or development teams. Professionals such as scientists, device manufacturers, and hardware manufacturers also create software code, although they are not primarily software developers. Nor is it limited to traditional information technology industries such as software or semiconductor companies. According to the Brookings Institute, these companies represent “less than half of the companies that develop software.”

An important difference is the development of customer-specific software, unlike the development of commercial software. Custom software development is the process of designing, creating, deploying and managing software for a specific group of users, functions, or organizations. In contrast, standard commercial software (COTS) is designed for a wide range of requirements so that it can be packaged and marketed and distributed commercially.

Steps in the software development process
Software development usually involves the following steps:

  1. Selection of a methodology to define an application framework for the software development stages. It describes an overall work process or a roadmap for the project. Methods include agile development, rapid application development (RAD), scaled agile framework (SAFe), and others.
  2. Collect the requirements to understand and document what users and other stakeholders need.
  3. Select or create an architecture as the underlying structure in which to run the software.
  4. Development of a design to solve problems arising from requirements, often including process models and storyboards.
  5. Create code in the appropriate programming language. Includes peer and team reviews to fix problems early and build high-quality software faster.
  6. Tests with pre-planned scenarios as part of software design and coding – and performance tests to simulate load tests on the application.
  7. Manage configurations and errors to understand all software artifacts (requirements, design, code, test) and to create different versions of the software. Set quality assurance priorities and approval criteria to troubleshoot and track bugs.
  8. Deploy software to use and respond to and resolve user issues.
  9. If necessary, migrate data from existing applications or data sources to new or updated software.
  10. Manage and measure the project to take care of quality and delivery across the appliance lifecycle and to gauge the event process using models like the potential Maturity Model (CMM).

The stages of the software development process are integrated into the application lifecycle management.

  • Requirements analysis and specification
  • Conception and development
  • Test
  • Use
  • Maintenance and assistance

The stages of the software development process can be divided into phases of the life cycle. However, the meaning of the life cycle is that it is recycled to allow continuous improvement. For example, user issues that arise during the maintenance and support phase may become requirements at the start of the next cycle.

Why is software development important?
Software development is important because it helps companies differentiate themselves and become more competitive. It can improve the customer experience, bring more innovative products with multiple functions to market faster, and make operations more efficient, safer and more productive.


Key features of effective software development
Using software development as a way to differentiate brands and gain a competitive advantage requires knowledge of techniques and technologies that can speed up the delivery, quality and efficiency of software.

  • Artificial Intelligence (AI) – AI allows software to make and learn from human decisions. Neural networks, machine learning, natural language processing and cognitive skills offer developers and businesses the opportunity to offer products and services that disrupt markets and stay ahead of the competition. IBM Watson allows developers to connect to and use artificial intelligence services as part of their applications through application programming interfaces or APIs.
  • Native cloud development – Native cloud development is a way to build applications to take advantage of cloud environments. A native cloud application consists of discrete, reusable components called microservices that can be integrated into any cloud environment. This architecture allows native cloud applications to use cloud environments to improve application performance, flexibility and scalability.
  • Cloud-based development – Just as IT organizations are looking to the cloud to improve resource management and reduce costs, so too are software development organizations. In this way, the cloud can be used as a fast, flexible and inexpensive integrated development environment (IDE) or a development platform as a service (PaaS). Cloud-based development can also provide access to APIs, microservices, DevOps and other development tools, services and expertise.
  • Blockchain – Blockchain is a secure, digitally linked registry that eliminates costs and vulnerabilities caused by parties such as banks, regulators and other intermediaries. It transforms businesses by freeing up capital, speeding up processes, reducing transaction costs and much more. Blockchain offers a huge opportunity for software development. Developers are working with distributed registers and open source Hyperledger technology to change the way businesses operate.
  • Low code – Forrester defines low code as follows: “Cloud products and / or services for developing applications that use visual declarative techniques instead of programming and are available to customers at low cost or free for money and training … “In short, it is a development practice that reduces coding requirements and allows non-coders or citizen developers to create or help create applications quickly and inexpensively.
  • Analytics – The analytics demand shows how important it is for companies to gain knowledge and skills. value from the data explosion. As a result, software developers integrate advanced analytics into their applications. Cloud-based services and APIs simplify control of data mining, automate predictive analytics, and create dashboards that provide new information and improve decision-making.
  • Mobile – 54% of world leaders believe that customer buying behaviour has shifted from products and services to experiences. Many of these experiences occur in mobile environments. An important function for software developers is the creation of mobile applications with deep data connections that enrich and improve the user experience. Forrester found that “the deep integration of digital / mobile customer data has a big impact on how customers interact with brands.”
