What is Software Development?
Software development is the process of designing, coding, testing, deploying and maintenance of software applications. These apps are designed to accomplish individual processes or resolve specific problems, and developing them follows a formalized sequence known as the Software Development Lifecycle (SDLC). This lifecycle makes the software efficient, robust, and customized according to users’/stakeholders’ requirements.
Software consists of a set of programs, designed and instructed to perform specific tasks, defined through codes, programming languages incorporated into it. Examples of software include system software that operates hardware and devices, application software for end-user particular tasks, and programming software that helps create more software. The software development process ranges from low-level programming language writing, like assembly instructions, to complex high-level assembly codes.
Software development comprises different roles, such as software engineers, developers, or programmers—all involved in doing fine work guided by someone else. When Software Development started, early programs were stored on physical media, from floppy disks to CDs and DVDs. The modern era, where software is easily downloadable and updated through the internet, marks a significant shift from when most software was born bundling itself with its only hardware.

Top 4 Software Development Methodologies
A software development methodology is a framework used to structure, plan, and control the information system development process. These methods ensure effectiveness, flexibility, and excellence in development work.
1. Agile Development Methodology
The Agile approach emphasizes iterative and incremental work sequences, flexibility in planning, and small increments of development over time with customer feedback. The development process consists of sprints; a small part of the product is developed simultaneously. Continuous testing and review of the implemented code highlight Agile’s focus on quality. It benefits flexible projects like mobile app development or custom software solutions.
2. Waterfall Development Methodology
Waterfall is a sequential, phase-by-phase software development method in which each phase (requirements, design, implementation, testing, and maintenance) must be completed before proceeding to the next. It’s ideal for projects with precise and stable requirements, such as large-scale enterprise systems or infrastructure projects, but it’s less suitable for long-term projects with evolving requirements.

DevOps is well-suited to cloud-based applications, enterprise-level software, and projects that require constant maintenance and updates, enhancing speed and reliability.
How To Develop a Software?
Software development process often interchangeable with software development lifecycle, starts with analyzing the initial requirements like cost of developing software, revenue potential, programming languages to be used and scalability, after the requirements are discussed with the stakeholders and design it is documented to create a Software Requirement Specifications (SRS) document.
Here is a step-by-step guide on how to develop a software:
1. Requirement Gathering
This phase involves collecting and documenting software requirements from stakeholders like clients, business analysts, and developers. It results in a Software Requirements Specification (SRS) document outlining the software’s functionalities, features, and challenges. This phase also involves selecting Software Development Kits (SDKs), programming languages, and platforms.
2. Feasibility Study
A feasibility study assesses whether the project is viable regarding resources, costs, and technical risks. It ensures the project is technically feasible, economically sustainable, and aligned with company goals. The study explores technical options, evaluates potential challenges, and recommends continuing or revising the project.
3. Planning
Planning defines a comprehensive roadmap for resource allocation, task timelines, and milestones. This phase also involves choosing the appropriate software development methodology, like Agile or Waterfall. The result is a Software Development Plan that guides the development team.
4. Software Design
Developers create a blueprint for the system architecture, finalizing programming languages, frameworks, and development tools. The Software Design Document (SDD) outlines both functional requirements (what the software does) and non-functional requirements (e.g., speed, security). This ensures alignment with the project’s goals.
5. Testing
Software testing checks the application’s functionality and quality. It includes functional testing (validating that the software performs the required tasks) and non-functional testing (like security, performance, and usability). Both manual and automated tests are conducted to detect bugs, inconsistencies, and vulnerabilities. Continuous testing during development ensures smoother integration and deployment.
6. Integration
Integration combines different parts of the software into a unified system. This phase ensures subsystems communicate well, often through APIs connecting different software services. Software components are considered fully integrated when they function seamlessly across various environments.
7. Implementation
Implementation deploys the software into a live production environment. It involves setting up the infrastructure, configuring the service, migrating data, and training users. The software is available to end users, and ongoing monitoring ensures smooth operations.
8. Software Maintenance
Software maintenance is the post-launch phase, where the software is kept functional and up-to-date. It includes fixing bugs, addressing user-reported issues, improving performance, and adding new features. Maintenance ensures the software meets user expectations and business objectives over time.
