The process of large-scale software development is the backbone for your further business growth. However, this process differs from regular app development, so you should organize the process right along with exploring all intricacies and considering vital aspects that will affect your final project deliverables. Let’s outline the main steps you need to take to achieve your goals.

1. Gather and clarify requirements

According to your business’s specifics, large-scale applications focus mainly on scalability. With the increase in traffic, your current functionality might not handle the changes, while alternative development options may seem costly.

So, the first step is to consider your expectations and the features of your final solution. This entails collecting relevant information about the future solution, defining timelines and scope of tasks, evaluating technical feasibility, and setting project budget and team structure.

2. Choose software architecture

Choosing the correct architectural pattern lays the groundwork for the future development of your project. Deciding whether to choose a layered, event-driven, microkernel, or microservice architecture, you will make a decision you won’t change in the process. Each of these options is most suitable for different application needs and requirements.

For example, layered architecture is suitable for more time-constrained projects and traditional business applications. However, this solution is not ideal for large-scale software systems that require built-in scalability as the core.

Event-driven architecture is most suitable for developing asynchronous systems and user interfaces. This solution may be ideal for large systems, but before choosing it, you need to check specific technical criteria for your application before implementing it.

The microkernel architecture best suits applications with a broad target audience, instances that distinguish between primary and higher needs, and core and dynamic routines.

Microservices architecture allows more flexibility, many integrations with third-party services, and scalability opportunities. Microservices architecture is most suitable for rapidly growing applications. Developers can use different tech stacks for various app components and build separate services that won’t affect the software system.

3. Establish inter-team coordination

Inter-team coordination is essential to software development process predictability, high team commitment, and workflow efficiency. All elements of a single development mechanism must work synchronously.

Inter-team coordination enables rapid exchange of information, faster requirements clarifications, and problem-solving. Adopting such an approach is imperative for complex projects, where the scope of work is vast and time-consuming, and there is a high degree of interdependence between different workflows.

4. Elaborate on large-scale system design

The overall system design strategy should aim for simplicity and ease of use for any system with many components and complexities. Based on our real case experience, the Northell team prioritizes the technology toolkit to support a large scale. To achieve this, we choose a scalable application infrastructure required for reliable large-scale software development.

5. Move to development

The core development phase entails the intensive developers’ work on implementing the agreed features of your final solution. Depending on the type of methodology and defined scope of work, developers implement features step by step. In the case of large-scale software development, our team sticks to a mixed development approach to ensure timely risk mitigation and requirements compliance while adopting regular changes to enhance the customer experience.
