Domain-Driven Design
DDD is an approach to software development that focuses on creating a solution model based on the particular business domain and the domain logic it’s designed for. The creative collaboration between domain and technical experts results in formulating a shared understanding of the business challenges and the requirements to address them, which provides us with a solid foundation for software design & development. DDD is highly effective for complex domains, where attending to problem complexity is a must in order to design the right solution.
Test-Driven Development
TDD is a development practice that tightly interweaves design, coding, and testing. This results in a better understanding of the product requirements and puts focus on software quality first. Such an approach increases development confidence and productivity, while significantly decreasing the cost of change over time. This is due to the fact that, when a piece of code fails a test, the developer can proceed to fixing it right on the spot, as opposed to excessively debugging at later stages.
Behavior-Driven Development
BDD encourages close collaboration between developers, QAs, and business representatives (domain experts). The goal of this collaboration is formulating a shared understanding of how the software is going to behave. BDD puts the business in the driving seat to produce software that lives up to the expectations of its stakeholders. Focused on building highest-value capability first, Behavior-Driven Development reduces the risk of budget overrun, while ensuring the application meets all requirements and is stable in production from the get-go.
Spec-Driven
Xolvio’s original approach to software development, Spec-Driven puts specifications at the center of the product development life cycle. Specs are the communication of design that leads to a shared understanding, which in turn leads to speed and quality. Spec-Driven encompasses each phase of the SDLC, starting from discovery and architecture, through infrastructure and development, all the way to testing, quality assurance, and deployment. Spec-Driven builds upon both BDD and TDD practices, but also includes UX design, project management & facilitation techniques.
Targeted Quality Assurance
Our great focus on software architecture and specifications gives us laser-sharp tools not only to build high-quality software products, but also to verify them. The fact that we always write and gather specs with utmost care means we can test for those specs being met far quicker and with more confidence. In addition, we use a powerful blend of automated and manual testing, so that we lock in the value not just for the present, but also for the future. Finally, we leverage a combination of advanced techniques like visual regression testing, integration testing, and contract testing, as well as deploying to dynamic QA environments that facilitate a faster workflow. All of this makes your solution a flawlessly polished diamond, way before you’d expect it to be perfect.
Pragmatic Agility
In each and every project we work on, we manage our workflow through a Kanban-style system that allows us to continuously respond to your needs and change requests. This is possible thanks to the emphasis we put on creating flexible software architecture. By employing progressive and evolutionary design methods, we make sure that your solution’s architecture is as malleable as possible and can be easily adapted when needed. Last but not least, we constantly improve software through Kaizen practices as part of our continuous improvement mindset.
