Software Development Process: How does it differ from SDLC?

Trends & Technology

The terms Software Development Process and Software Development Life Cycle (SDLC) are often used interchangeably. Even when both terms are searched on Google, similar results appear.

What Is the Software Development Process?

The Software Development Process is a set of activities, principles, and methodologies that enable the management of software creation. It is a comprehensive process that defines how software is developed, what rules and tools are used, and how the team and project are managed. This process can take various forms, such as Agile, Waterfall, DevOps, or other approaches.

It encompasses all the steps necessary to develop, deploy, and maintain an application or system. These steps typically include requirements gathering, design, coding, testing, and maintenance. The process is not rigid—different teams may apply different approaches depending on the needs of the project, team, or industry.

What Is SDLC?

SDLC (Software Development Life Cycle) refers to a detailed model of the software life cycle. It covers all phases that software goes through, from initiation and planning to deployment and maintenance.

SDLC is a structured way of managing software development, where each phase has clearly defined tasks and goals.

Typically, SDLC consists of seven phases:

  1. Requirements Gathering – Analyzing the business needs and user expectations that the software is expected to meet.
  2. Analysis – Carefully reviewing the requirements and assessing their feasibility from a technical standpoint.
  3. Design – Developing the structure of the software, including both the system architecture and user interface.
  4. Implementation – Writing the code, i.e., the actual creation of the software according to the project’s design.
  5. Testing – Ensuring that the software functions according to the requirements and is free of errors.
  6. Deployment – Releasing the software to users or deploying it into a production environment.
  7. Maintenance – Monitoring the software’s performance, resolving issues, and adding new features as needed.

How Do the Software Development Process and SDLC Differ?

Although Software Development Process and SDLC are closely related, there are key differences between them.

  1. Scope – The Software Development Process is a broad term that encompasses various methodologies, techniques, and tools used in software development. SDLC, on the other hand, focuses on specific, well-defined stages of the software life cycle.
  2. Flexibility – The Software Development Process can include different approaches and methods tailored to the specific needs of the project. SDLC is usually a more formal, structured process with clearly defined phases, often used in more complex or demanding projects.
  3. Purpose – The goal of SDLC is to provide structure and control over the software life cycle, helping to predict budgets, schedules, and resources. The Software Development Process, however, focuses on organizing the workflow, integrating tools, teams, and processes to maximize efficiency.
  4. Application – SDLC tends to be more rigid, while the Software Development Process can be more flexible and dynamic, especially in agile methods like Agile or DevOps, where adapting to changing requirements and fast iterations is key.

In summary, SDLC is a more detailed part of the broader Software Development Process. While SDLC outlines the specific steps, the Software Development Process also includes how these steps are executed.

Code Refactoring: Best Practices, Techniques & Tools

The code refactoring process involves restructuring existing code without changing its external behavior. It’s like renovating a house to enhance its functionality and aesthetics while keeping the foundation intact.  Code refactoring doesn’t fix bugs or add new features — it’s improving the overall design, readability, and performance of the code. Let’s explore the importance of […]
