How we work

Two crucial aspects in developing your custom business application:

    • The quality and effectiveness of the delivered solution: How well does the application meet your business needs in terms of performance and robustness?
    • Time-to-market:  A short time-to-market is critical to capitalize on new market opportunities.

    Our project methodology is perfectly aligned with these aspects:

    • Agile

      With over twenty years of experience in Agile practices, ACA Group is renowned as an Agile thought leader. An Agile process integrates the stages of analysis, development, testing, and delivery into a continuous cycle. We work in short iterations of a few weeks, allowing continuous feedback from you, our client, and adjustments as needed. This keeps us in line with your desires, ensuring the final product fully meets your business needs.

    • True collaboration

      Understanding your business processes and environment is key to building software solutions perfectly aligned with your needs. Using Domain Driven Design (DDD), event storming, and user story mapping workshops, we collaboratively map out your domains, processes, and requirements. During the development phase, you remain fully involved, working alongside the development team virtually. This ensures you are always informed about your project's status, allowing us to respond swiftly and with full transparency and trust.
