Our Java development process

At DigitalMara, we really care about making the whole working process comfortable for our clients. We strive to ensure that each stage runs smoothly and with clear communication. We help you navigate through all of the various steps, from identifying needs to project launch, as well as follow-up technical maintenance. We value providing you with top-notch development expertise.
1
Project analysis

This first stage involves meeting with the customer to gather ideas and define needs and requirements. We’ll analyze the number and complexity of features required. And, of course, we’ll identify where there might be bottlenecks and propose solutions. Then our Java experts will suggest the best model for our cooperation on your specific project.

2
Analysis and Design

Together, we’ll create the project specification, with detailed information about each portion of the development. This detailed brief will provide a portrait of what your project will look like. We’ll also create a roadmap of the project and a list of all the Java services we will incorporate

3
Project Development

At this stage, the team starts to turn everything approved in the specifications documents to reality. Don’t worry! Our experience tells us that even perfect project specifications may have their gaps. We’re ready for that and will solve any problems that arise without additional hassles on your part.

4
Testing

It’s important to triple check to be sure your project meets all your expectations. To guarantee the highest quality in all our Java development projects, we apply QA and testing practices in every part of the development lifecycle. This minimizes any troubles in the final stage. Our experienced QA engineers are prepared to check each line of code, and to speed up the process they may apply automated testing.

5
Launch and Maintenance

It’s what you’ve been waiting for; the most exciting (and anxious) stage of all. Our Java team will help with deployment of the product and make sure everything is working as it should be. We keep our finger on the pulse of your project, to help you to implement any additional features you need in future
