Serious Design/Domain Driven Design
Serious Design
Serious design is a software development approach that emphasizes the importance of designing software that is both effective and efficient. Serious design principles include:
- Simplicity: Software should be simple to understand, use, and maintain.
- Modularity: Software should be composed of independent modules that can be easily combined and reused.
- Testability: Software should be designed to be easy to test, both manually and automatically.
- Extensibility: Software should be designed to be easily extended to accommodate new features and requirements.
Domain-Driven Design (DDD)
DDD is a software development approach that focuses on creating software that closely models the real-world domain that it represents. DDD principles include:
- Ubiquitous language: A shared language that is used by both developers and domain experts to communicate about the domain.
- Bounded contexts: Different parts of a software system that have their own unique domain models and rules.
- Aggregate roots: Objects that represent the core entities in a domain model.
- Value objects: Objects that represent immutable data values.
Relationship between Serious Design and DDD
Serious design and DDD are complementary approaches to software development. Serious design provides a set of general principles that can be applied to any software development project, while DDD provides a more specific set of principles and practices that are particularly well-suited for developing complex software systems that model real-world domains.
By combining the principles of serious design and DDD, software developers can create software that is both effective, efficient, and maintainable.
Examples of Serious Design and DDD in Practice
- Amazon: Amazon uses serious design principles to develop software that is scalable, reliable, and efficient. For example, Amazon’s e-commerce platform is designed to handle millions of transactions per day.
- Google: Google uses DDD to develop software that is closely aligned with the real-world domains that it represents. For example, Google Maps is designed to model the real-world road network.

Prerequisites
Before you can do Serious Design or Domain-Driven Design (DDD), you need to have a few things in place:
- A clear understanding of the problem domain: This includes a deep understanding of the business goals, the users’ needs, and the constraints of the system.
- A shared language between developers and domain experts: This is essential for effective communication and collaboration.
- A commitment to iterative and incremental development: Serious Design and DDD are both iterative approaches to software development. You need to be prepared to refine your design and implementation as you learn more about the problem domain.
- A supportive organizational culture: Serious Design and DDD require a culture that values collaboration, experimentation, and learning.
In addition, you may need to have certain tools and technologies in place, depending on the specific approach you choose. For example, if you are using EventStorming, you will need a whiteboard or other large surface to capture your ideas. If you are using DDD, you may need a modeling tool such as UML or BPMN.
Here are some specific things you can do to prepare for Serious Design or DDD:
- Educate yourself: Learn about the principles and practices of Serious Design and DDD. There are many resources available online and in libraries.
- Talk to experts: If you know anyone who has experience with Serious Design or DDD, reach out to them and ask for advice.
- Start small: Don’t try to tackle a large and complex project right away. Start with a small project that you can easily manage.
- Get feedback early and often: Share your work with others and get their feedback. This will help you identify problems early on and make necessary adjustments.
By following these steps, you can set yourself up for success with Serious Design or DDD.
What’s next?
After you have implemented Serious Design and Domain-Driven Design (DDD), the next steps will depend on the specific project and your organization’s goals. However, some common next steps include:
- Iterative refinement: Serious Design and DDD are iterative approaches to software development. Once you have a working system, you can continue to refine it based on feedback from users and stakeholders.
- Scaling: If your system is successful, you may need to scale it to handle more users or data. This may involve deploying your system to a cloud platform or using a distributed architecture.
- Integration with other systems: Your system may need to integrate with other systems in your organization. This may involve developing APIs or using message queues.
- Maintenance and support: Once your system is in production, you will need to maintain and support it. This may involve fixing bugs, adding new features, and responding to user inquiries.
In addition to these technical considerations, you may also need to consider the following:
- Organizational change: Serious Design and DDD can require significant changes to the way that your organization develops and deploys software. You may need to provide training and support to help your team members adapt to these changes.
- Cultural change: Serious Design and DDD can also require changes to your organization’s culture. For example, you may need to create a culture that values collaboration, experimentation, and learning.
By following these steps, you can ensure that your Serious Design and DDD project is successful in the long term.
Here are some specific examples of what comes next after Serious Design/DDD:
- Amazon: After implementing Serious Design and DDD, Amazon continued to refine its e-commerce platform to handle more users and data. The company also integrated its platform with other systems, such as its物流 centers and customer service system.
- Google: After implementing Serious Design and DDD, Google continued to refine its Maps application to add new features and improve the user experience. The company also integrated Maps with other Google products, such as Search and Street View.
- Netflix: After implementing Serious Design and DDD, Netflix continued to refine its streaming platform to improve the quality of service and add new features. The company also integrated its platform with other systems, such as its content delivery network and billing system.
These are just a few examples of what comes next after Serious Design/DDD. The specific next steps for your project will depend on your specific needs and goals.
