What Is Software Development? [Benefits + Career Opportunities]

Have you ever wondered how the apps on your smartphone or the websites you browse come into existence?

Both are the results of an intricate process known as software development.

If youre interested in software development in the UK, this article will dive deep into the topic.

Well explore what software development truly is, as well as explore its benefits and step-by-step process.

If you want to pursue a career in software development, well also discuss some of the promising job opportunities, along with their salary ranges.

Without further ado, let's get started!

What is Software Development?

Software development is a systematic process that involves designing, coding, testing, and maintaining software to meet specific needs or solve particular problems.

It involves a series of steps that transform an idea into a functional and reliable piece of software.

Software developers are able to create a wide range of applications and systems across various domains.

Here are some popular types of software development:

  • Web applications: Software that runs on web browsers, such as e-commerce websites and social media platforms.
  • Mobile applications: Specifically designed for iOS or Android devices, these software types cover categories such as mobile games and productivity tools.
  • Desktop applications: Software that users can download on desktop operating systems like Windows, macOS, or Linux. These include productivity tools, entertainment software, and business applications.
  • Embedded systems: This type of software is made for hardware devices like smart appliances, medical devices, and industrial machinery.

What Makes Software Development Important?

You might wonder, why is software development so popular among solo entrepreneurs and businesses?

The reason is because software development provides the tools and systems needed to navigate the challenges and opportunities of the digital age.

Here are other reasons that highlight the benefits of software development across different sectors:

  • Automation and efficiency: Productivity solutions allow the automation of repetitive tasks, which increases efficiency and reduces the margin of error.
  • Innovation and progress: Software development drives the creation of new technologies, products, and services.
  • Enhanced user experience: Well-designed interfaces and intuitive navigation systems improve user experience, whether youre building a website, mobile app, or desktop.
  • Security and privacy: Software developers play a critical role in creating secure applications and systems. As cyber threats evolve, continuous development and updates are essential to protect sensitive data and maintain user privacy.
  • Customisation and adaptability: Businesses can adjust software solutions to meet their specific needs. Also, bespoke software allows organisations to adapt to changing requirements.

7 Steps in the Software Development Process

Software development is a systematic approach that involves a series of steps to design, create, test, and maintain software.

While the methodologies may vary depending on the software type, here are the key fundamentals of successful software development:

1. Requirements Gathering

The first step involves understanding and gathering requirements from stakeholders.

This includes discussions with clients, end-users, and other relevant parties to identify the purpose and functionalities expected from the software.

To do so, developers need to conduct meetings and interviews with clients, end-users, and other stakeholders.

The expected output is a requirement specifications document which elaborates what the software must accomplish.

2. Planning

Once the requirements are established, a comprehensive plan will be created.

This phase involves defining the scope of the project, estimating timelines, allocating resources, and identifying potential risks.

The plan serves as a roadmap for the entire development process, so the team can create a project schedule and establish milestones clearly.

3. Design

In the design phase, developers will create a detailed blueprint of the software based on the gathered requirements.

This includes architectural designs, data structures, and the overall system structure.

The goal is to create a clear guide for the coding phase.

More importantly, the design phase is where the whole user journey is mapped out.

By doing so, you can ensure a seamless browsing experience, from the moment users visit your software to when they finally convert.

4. Implementation

This is where the actual coding of the software takes place. Programmers will write code using programming languages, following the design specifications.

The coding phase is crucial in transforming the conceptual design into executable code, since the developer should follow coding standards, while continuously testing and debugging.

5. Testing

After coding, the software undergoes testing to ensure that it meets the specified requirements and functions as intended.

Testing includes unit testing (testing individual components), integration testing (testing how components work together), and system testing (evaluating the entire system).

6. Deployment

Once testing is successful, the software is deployed to the target environment.

Deployment involves installing the software on servers, cloud platforms, or other computing devices, making it accessible to end-users.

7. Maintenance

Software development doesn't end with deployment.

The maintenance phase involves addressing issues that arise post-deployment, applying updates, and making improvements based on user feedback.

This ensures the software remains reliable and up-to-date.

Those steps are often represented in various software development life cycle (SDLC) models, such as the Waterfall model, Agile model, or Iterative model.

Some methodologies, like Agile, may emphasise iterative development with frequent testing and client feedback, while others, like Waterfall, follow a more linear progression through these steps.

To develop a successful software, consider hiring a trusted software consulting firm. They will guide you through each stage of the development process, helping you minimise risks and maximise results.

What are Jobs that Use Software Development?

Some jobs in the IT industry heavily rely on software development. Here are some of them, along with explanations of why it is essential for their functions:

1. Software Developer

Software developers are directly involved in the creation of software applications. They write code, design algorithms, and ensure that the software meets specified requirements.

Some examples of their duties are writing, testing, and maintaining code, while collaborating with stakeholders to understand requirements.

Besides that, software developers also use various programming languages and tools to build functional applications.

Salary Ranges

  • Junior/Entry Level: £40,000 - £55,000
