Transforming Legacy with Domain-Driven Design, VI: Results
- Domain-Driven Design (DDD) was adopted in the project and was implemented within a timeframe of about two years post-prototype implementation to fully adapt the department to the new architecture.
- A core principle of DDD is creating a shared language between domain experts and developers. The interaction between developers and analysts improved, and despite having a strong grasp of the domain, the analysts lacked a unified model for describing it.
- Before implementing DDD, the onboarding process for new developers typically took about six months to acclimate to the project. With DDD, the onboarding process became much simpler and new developers could gradually learn domain details through task execution.
- DD introduces significant change, positively impacting employees by easing the process for both the new hires and their mentors, opening up new development opportunities, and helping resolve technical issues.
- One of the first major achievements of DDD adoption was the launch of a new electronic trading platform in a neighboring country that took just a month to accomplish, making the company the first platform in the country to offer this functionality, increasing company revenue.
- After migrating the main platform to the new architecture, the company ranked first in the national ranking of electronic trading platforms based on corporate customers' satisfaction with service quality for three consecutive years.
- DDD simplifies certain system components, such as contexts, layers, entities, and classes. However, overall system complexity inevitably increases.
- DDD should be used for projects planned for long-term support and truly complex domains with extensive business logic, where it is essential for the project's successful development and scalability.
