What is the difference between Brownfield and Greenfield Software Development?


Today, the software industry is one of the fastest-growing industries in the world. Product managers and developers are working side by side to employ innovative ways to create new cutting-edge products. With every passing day, the competition in the software market is getting higher. Moreover, digital transformations are playing a central role in increasing customer expectations. The need of the hour is to develop software solutions that meet the changing demands of end-users and have a competitive advantage in their relevant verticals.

For this purpose, software development methodologies and techniques are used that follow a streamlined path and produce the desired high-quality end-product. Greenfield and brownfield development are two approaches that are used by the software industry to produce high-end software products. This article gives a comprehensive overview of both greenfield vs brownfield deployment, and their advantages, and disadvantages for the software industry.

Greenfield Software Development

Greenfield software development refers to the development of a brand new software product. From research to product planning, architecture to coding, and implementation to deployment, greenfield software development starts with a fresh approach. This approach is used by the software houses when there is a product that needs to be started with an open-ended approach, there are no restrictions, no standards, and no dependencies at the moment.

In the greenfield software development approach, you are unaware of the scope of the project. You get to know the limitations and strategies with time and based on the current state, such technologies and design aspects are employed that better fit the need of the product. In the greenfield waterfall development plan, smaller modules are developed, a plan for the minimum viable product (MVP) is created, the first draft of a working version is developed and it is sent to the testing phase. 

With the development of major modules, a working infrastructure of the product is evaluated against its clientele base, and the constraints are identified. Transformations are made until the product is in its desired form. However, today greenfield projects are very rare. Instead of starting from scratch, we use third-party apps and tools integration to increase the scope of our projects and take assistance from the existing code of some module. Greenfield software development thus focuses on developing an application or website from the ground up, the APIs are freshly developed, data centers, search engines, and other software engines are developed from scratch.

Examples of Greenfield Development

Some greenfield project examples include:

  • Building an eCommerce platform that is new and has not been used before.
  • Developing the rules engines that support the development of multiple products.
  • Writing new technology stacks and languages with enhanced support and no previous code is used in it.
  • Developing data centers with fresh groundwork.

Advantages and Disadvantages of Greenfield Development:

Every software development approach has its own advantages and disadvantages. Greenfield software development follows a defined path to plan, build, develop, test, and deploy every single module.

The advantages of greenfield software development are:

  • It allows you to dig deep into technology, identify nitty-gritty details, and acts as an opportunity to give attention to detail and learn more.
  • Hands-on experience in building a roadmap and implementing the modules.
  • Getting a detailed overview of the software infrastructure and the limitations in existing systems.
  • There are no constraints or limitations tied to the system you are developing. You just follow the path and mitigate the risks dynamically.

The disadvantages of greenfield software development are: 

  • Though you have started the work there is not a surely defined roadmap for you to follow since you are a pioneer.
  • The risk in software development is comparatively high in this approach.
  • More time and effort are required to dig out the details and make a plan.
  • There is a wide range of options available from a development point of view, it gets hard to decide the one so that it does not introduce any challenges when it comes to the scalability of the product.
  • Decision-making is very hard as you might need to change something in the future.

Brownfield Software Development

Brownfield software development refers to the development of a new product using an existing chunk of code and legacy software systems. This software development approach is taken into consideration when a previously existing system needs to be improved with some additional functionalities and strong capabilities that make that product stand out. While developing a software product, it is, therefore, crucial to ensure the aspect of scalability so that there should be enough room and flexibility for improvements in the future. 

Brownfield software development involves extensive study of the development approach taken previously. An end-to-end code audit is performed extensively to get a clear overview of the next steps and what possible constraints could occur in between the processes. An in-depth report is shared between the different departments working on that project so that everyone gets an idea of what efficient measures are required. Moreover, it clears the future path to be followed. 

Usually, the same technology stack is used on which the application was built. Different checkpoints are identified where the new code needs to be embedded. The team of developers finds out the ways that could be used in order to develop the required solution. Once the requirements, state, and roadmap are clear, the team gets started with the best possible solutions.

Examples of Brownfield Development

Some examples of brownfield development include:

  • Addition of a new module in the existing system.
  • Implementation of new features and functions in the enterprise software.
  • Improvement of certain modules to increase efficiency and performance.
  • Upgrading the code to increase effectiveness.
  • Improvements in speed of execution.
  • Redesigning the UI/UX of the software for seamless user interaction.
  • Implementing a module using advanced technology that meets the demands of the digital world.
  • Adding sophisticated features to the application so that value of the product in the market could be increased.

Advantages and Disadvantages of Brownfield Development

Brownfield software development has the ultimate focus on redeveloping a product such that its features could be upgraded by employing an advanced approach. 

The advantages of brownfield software development are:

  • You have a sample already present based on which new decisions need to be taken.
  • You have a clear idea of the scope, audience, competitors, and position of the product.
  • You get an opportunity to contribute to the improvement of the existing system.
  • Existing code could be reused efficiently to produce a market-leading product.

The disadvantages of brownfield software development are:

  • You should first have a complete understanding of the state of the products, the technology that is used in it, the data, and the flow of the product.
  • You might need to re-engineer the whole module as a requirement of adding new functionality into the app.
  • The technology stacks might not align with each other and you need to switch the technology to make the edits possible.
  • The development cost becomes high when you are dealing with legacy software systems.

A clear overview of greenfield vs brownfield technology helps identify the pain points and limitations of both software development approach in a detailed manner.
