The Ultimate Guide to Software Development Process


Statista predicts that the revenue in the software market will reach $824,848 billion in 2026. But, to leverage the numbers - a methodical approach to the end-to-end software development process is essential for any software development project. And every well-defined and clear software development lifecycle results in a fantastic piece of software.

If you go in the right direction and adhere to a pre-determined software development life cycle, you will be able to create outstanding end-user software.

With the emergence of top software development trends, you will have a plethora of software development processes to select from for your software development life cycle. However, the question is, which software development lifecycle is best for you? Which software development process will result in a successful product?

If you are also looking to develop feature-rich software and are confused with the above questions, then we have got you covered. 

In this software development process guide, we as leading software development company are going to cover everything about software development, the software development lifecycle, and different methodologies. Let’s dig down. 

What is Software Development?

Software development is the detailed process of conceiving, crafting, validating, and maintaining computer programs and applications, meticulously tailored to execute specific tasks or functions. Software engineers employ various programming languages and tools to compose code that prescribes precise instructions to computers, to get the desired results. 

The paramount objective of software development is to provide robust and dependable software solutions that not only meet client requisites but also automate operations and confer added value upon end-users.The software development landscape is remarkably diverse, encompassing a wide spectrum from coding scripts and mobile applications to intricate, enterprise-grade software systems. It stands as a pivotal catalyst for innovation and enhanced operational efficiency across various industries.

What is SDLC (Software Development Life Cycle)?

The software goes through several process stages in the Software Development Life Cycle (SDLC) during the course of its lifespan. A detailed, sequential method for creating high-quality software is part of the software development life cycle. And if any of the phases are skipped, all of the software development efforts would be for nothing.

Steps in the software development life cycle include gathering requirements, designing, developing, testing, deploying, and maintaining the product.

Now that you are aware of the true definition of the software development life cycle (SDLC), it is necessary to comprehend its importance.

  • Safe & secure process: Using meticulous procedures throughout the software product development phases reduces the likelihood of errors and faults while producing a high-caliber final result.
  • Lesser development time: It reduces the development and turnaround time with dedicated developers working on each phase and the standard approach.
  • Real-Time Collaboration: Development teams can work together for full-swing communication thanks to the stages of the SDLC. Therefore, each team member must understand what to anticipate and how to prepare for the next move.
  • Project Management Control: Regardless of the project size, the software development life cycle provides project management control to assist developers in visualizing and tracking the software development lifecycle.
  • Clearly defined roles and responsibilities: The SDLC has specific objectives for each stage. Because of this, each team member is aware of what they are supposed to be doing along the software development life cycle.

Stages of Software Development Life Cycle: Explained in Detail

Our team at Netclues, the leading custom software development company will be explaining the end-to-end software development lifecycle. Let’s dig down.

Stages of Software Development Life Cycle

Requirements Analysis and Project Planning

The initial phase of software development involves analysis, discovery, and project planning. During this phase, the developer examines the requirements, business objectives, and challenges identified by the customer to start imagining how to implement the software vision. 

The primary objective of business analysis is to analyze and record the main software goals and the tasks necessary to achieve them. To discuss the intricacies of the software, such as its components, dependencies between its aspects, structure, potential design needs, etc., the client and the software development business must work closely together. 

This stage even includes preparing a document that summarizes the client's vision for the finished product, describes the aims of the project, and lays out its technical needs.

A conceptual framework model for the project is part of the discovery process, which comes after the preliminary business analysis. The foundation of the software product's effective development and execution is a comprehensive, high-quality analysis of the upcoming work, its potential difficulties, and its end-user functionality.

Software Design and Prototyping

The design phase in the software development lifecycle is a critical stage where the overall structure and architecture of the software system are planned and defined. It sets the foundation for the upcoming steps of software development lifecycle. A meticulously conceived design plays a pivotal role in ensuring that the software exhibits efficiency, scalability, and perfect alignment with user expectations and business imperatives.

  • Architectural Design: This pivotal phase involves the delineation of software components, their interrelationships, and the overarching structure, effectively crafting a blueprint for the software.
  • Detailed Design: Thereafter the Programmers and designers work on the detailed design of individual components and modules. They work together on each part of the software which includes defining data structures, algorithms, and interfaces.
  • User Interface (UI) Design: UI design involves creating wireframes, mockups, and designs for the user interaction elements for the layout, visual design, and user experience considerations.
  • User Experience (UX) Design: UX experience design includes creating a user-friendly and intuitive interface for the software. It involves considering the end-user's needs, preferences, and the overall user journey within the application.

Quick Note: The design should align with the target audience, and ought to be appealing, unique, and functional to attract the audience and get desired solutions.

Software Development Phase

When you have completed your final requirements, wireframe, and prototype, and are confident with your UX design, the most important part of software production begins. The software engineers begin work on the development by selecting their programming language for corporate software development.

This phase of the custom software development process is typically the most time-consuming, as it concludes with a nearly finished, functional product.

The software will go through the following stages at this point:

  • The software version before and during the development phase is known as pre-alpha. Pre-alphas are far from a final product; they are typically prototypes or design concepts.
  • The alpha version is an initial draft of the software. Although it encapsulates most of the features and functionalities outlined during the design phase, it can still be susceptible to significant flaws or exclude varied vital components.
  • The beta version represents a more comprehensive and refined iteration of the software, yet it remains in a pre-distribution state. Beta versions undergo rigorous testing procedures aimed at identifying and rectifying bugs or concealed issues before final release.
  • A release candidate is a completed beta version that has the potential to be issued to the client. As of now, every aspect of the software has been developed and put into use, and user-centered testing is being done.

QA and Testing

When the code is finished, it must be verified that it satisfies the requirements in order to guarantee that the software product resolves end customers' problems.At this step, quality assurance engineers conduct manual and automated testing to identify any bugs, system problems, or defects. 

During this stage, you will see many types of functional testing such as integration tests, unit testing, system testing, acceptability testing, design implementation testing, and so forth.

It is crucial to thoroughly evaluate the product against all accessible parameters, which is why this procedure is required. This step in software development lifecycle was traditionally performed after the development phase was completed. However, with the agile development method, test cases are executed at the end of each sprint cycle.

After quality assurance, engineers ensure that there are no system faults or flaws before deploying the software to production.

Software Deployment

Upon successful testing and satisfaction with the results, the software is poised for release to end users. The term "deployment" denotes the process of making the technology accessible to customers. Once all issues have been addressed, the software is primed for its final deployment!

The most critical responsibility here is to ensure that the code, data, and other components are deployed correctly. Additionally, it's critical to confirm that the provided solution satisfies all particular needs. 

The software development team also writes release notes in addition to that. These are technical docs that contain essential details about the program. It might cover new developments in technology or corrected flaws.  

As a result, after the product is complete, the first batch is released to the public. This is referred to as 'Beta testing'. If any adjustments are required as a result of client feedback, or if any bugs that were not discovered during the testing phase emerge, you can make the necessary changes.

Maintenance and Support

The software development lifecycle continues even after the release of a product. In the event that end users encounter an issue or a technical glitch, developers must be prepared to rectify it. Indeed, the flawless functioning of a solution upon initial delivery does not gurantee that there will no potential future bugs.

Furthermore, the infusion of new features and regular updates, whether major or minor, is indispensable to maintain the product's up-to-date and maintain competitive edge.

In this sense, the software development team is now in charge of modifying the digital solution to meet the target audience's ever-expanding needs.

In general, software development firms can provide customers with the four types of maintenance operations listed below:

  • Maintenance of corrective software. Its goal is to correct any bugs that have been discovered.
  • Proactive software upkeep. These tasks, as their name suggests, entail routine checks to reduce any technical problems with your digital solution.
  • Precise upkeep of software. These tasks involve improving the current solution through optimization and the addition of new features.
  • Software maintenance that adapts. It recommends modifying the program to meet your evolving company requirements, such as switching to the cloud or adjusting to new third-party tool regulations.

Types of Software Development Life Cycle Models

Types of Software Development Life Cycle Models

Waterfall Model

This approach, often denoted as the linear sequential model, stands as the most time-honored and methodical among all Software Development Life Cycle (SDLC) models. It operates in a meticulously step-by-step fashion, with each subsequent phase based on the outcomes of the preceding one.

Since one cannot go back to a stage once they have completed it entirely, it is important to work carefully and without making any mistakes.

Importance of the Waterfall method for software development: 

  • Predictability: The Waterfall Model provides a clear and predictable path from start to finish.
  • Documentation: Extensive documentation helps in understanding the project's history and current state.
  • Well-defined requirements: Suitable for projects with stable, well-defined requirements.
  • Regulated Change Control: Changes are tightly controlled and require formal approval.

When to Choose the Waterfall Model? 

  • Stable Requirements: When the project requirements are determined from the start and unlikely to change significantly during development.
  • Small to Medium-sized Projects: It's a good fit for smaller projects with clear objectives.
  • Regulatory Compliance: For projects in industries with strict regulatory requirements (e.g., healthcare, aerospace) where documentation is paramount.
  • Limited Client Involvement: When the client prefers a hands-off approach and is not interested in frequent involvement or iteration.


It's important to note that the Waterfall Model has limitations, particularly when dealing with rapidly changing requirements or when there's a need for frequent client feedback. In such cases, more flexible methodologies like Agile or Scrum might be more appropriate.

Agile Software Development Model

The Agile Software Development Model is a flexible and iterative approach to software development.  Agile breaks the project into smaller increments, often referred to as sprints or iterations. It encourages close collaboration between cross-functional teams, including developers, testers, and business stakeholders. This software development cycle aims to deliver a working product incrementally, providing value to the customer with each iteration.

Importance of utilizing the Agile software development model: 

  • Flexibility: Agile can adapt to changing requirements and priorities, making it ideal for dynamic projects.
  • Customer Satisfaction: Frequent customer feedback ensures that the software aligns with customer expectations.
  • Reduced Risk: Regular inspections and adaptations help identify and address issues early.
  • Shorter Time-to-Market: Agile often results in faster delivery of software.
  • Improved Collaboration: Close collaboration among team members fosters a sense of ownership and collective responsibility.
  • Quality Focus: Agile methodologies often incorporate testing and quality assurance at every stage.

When to Choose the Agile Model? 

  • Changing Requirements: When the project's requirements are expected to evolve or are not well-defined initially.
  • Customer Involvement: When the customer wants to be actively involved throughout the custom software development process and provide feedback.
  • Complex Projects: Agile can break down complex projects into manageable increments.
  • Innovative or Research-Oriented Projects: It's suitable for projects where exploration and experimentation are key.
  • Cross-Functional Teams: When you are dealing with a cross-functional team that includes developers, testers, and business stakeholders.


The Agile model may not be the best fit for projects with highly regulated environments or projects where detailed upfront planning and documentation are mandated. In such cases, a hybrid approach or a more structured methodology like the Waterfall Model might be more appropriate.

Iterative Development Model

The Iterative Development Model is an approach to software development that involves breaking a project into smaller, manageable cycles or iterations. It divides the project into different iterations, with each one focusing on specific aspects of the software. In each iteration, the team refines and expands upon the work done in previous iterations, adding new features, enhancements, or fixing defects.


  • Better end results: Iterative development refines the software incrementally, leading to an improved final product.
  • Risk Solution: Regular feedback and testing help identify and address issues early, reducing project risks.
  • End-to-End Involvement: Frequent iterations involve stakeholders, ensuring that the project aligns with their expectations.
  • Flexibility: It accommodates changing requirements and can adapt to evolving project needs.
  • Continuous Improvement: Each iteration aims to deliver a higher level of quality and functionality.

When to Choose the Iterative Development Model? 

  • Unclear Requirements: When initial project requirements are not well-defined, iterative development allows you to refine them over time.
  • Large Projects: For larger projects, dividing the work into iterations can make the development software development process more manageable.
  • Frequent Stakeholder Involvement: When you want continuous feedback from stakeholders and end-users.
  • Complex Systems: For projects involving complex systems or innovative solutions where learning and adaptation are essential.
  • Products with Evolving Needs: For software products with evolving or rapidly changing requirements.
  • Risk Management: Risk mitigation and early issue identification are high priorities.


The Iterative Development Model may not be the best fit for projects with very rigid, well-defined requirements, whereas a more linear approach like the Waterfall Model might be more appropriate.

DevOps Model

DevOps is a modern approach to software development that emphasizes teamwork between developers and IT operations. It's all about automating and streamlining the custom software development process to deliver software faster and more reliably. 

DevOps encourages collaboration, breaks down communication barriers, and eliminates manual tasks by using automation. It also promotes the use of Continuous Integration and Continuous Deployment (CI/CD) pipelines, where code changes are regularly integrated and deployed, making the development process more efficient and adaptable.

Importance of DevOps development methodology: 

  • Faster Delivery: DevOps enables rapid and frequent software releases.
  • Improved Collaboration: Better communication between development and operations teams.
  • Automation: Reduces manual and error-prone tasks, significantly enhancing efficiency.
  • Quality Assurance: Continuous testing and monitoring lead to higher software quality.
  • Risk Reduction: Faster identification and resolution of issues.
  • Enhanced Scalability: Infrastructure can be easily scaled to meet changing demands.

When to Choose the DevOps Model? 

  • Rapid Release Cycles: When you need to release software updates frequently.
  • Complex or Scalable Systems: For projects involving complex or scalable systems where automation can significantly improve efficiency.
  • Emphasis on Quality: For projects that prioritize high-quality software and ongoing monitoring.
  • Collaboration and Communication: In organizations where there's a need to improve collaboration between development and IT operations teams.

DevOps is not a traditional software development model but a set of practices and cultural principles that can be integrated into various development methodologies, such as Agile or Waterfall. It's suitable for organizations that aim to streamline and accelerate their software development and deployment processes.
