Strategy takes the lead
Every custom software development engagement starts with an envision phase - an engaging multi-day workshop where our custom software business analysis strategists take the time to not only understand your hopes and goals for the software solution but - more importantly - the core of your business and how technology can speak to that.

Designed to succeed
Out-of-the-box software is not totally user-friendly to your business because it was created for a wide audience with a one-size-fits-all mentality. But great custom software does not just deliver a service to it's intended users, but allows the software and the user to become one system, happily and efficiently creating value together. Achieving this amazing symbiosis requires that we gain an empathic understanding of users and apply that understanding to the design of their new experiences. That’s why every custom software development project at DOOR3 takes a decidedly user-centric experience approach that considered the user’s context with - and beyond - the screen and keyboard. Our UX UI design specialists then develop digital experiences that delight users while also helping them work smarter and more efficiently within their operating context.

Built for the future
Out-of-the-box software solutions can quickly become outdated, and more often than not, you’re already working on old technology the minute you activate your license. Our core software architects and engineers use modern platforms and frameworks, and design ahead to ensure extensibility and to maximize the lifetime value of your new custom developed software. Our front-end development experts work to embody that architectural vision in custom software that will support the future of your company as well as the present.

Testing for excellence
Our Quality Assurance QA team designs testing protocols and deploys automated QA when appropriate to ensure that your custom developed software meets and exceeds expectations and can always be re-tested quickly any time even a minor change is made to the code. We also work with you to prioritizing any identified defects to ensure that high-impact defects are eliminated and low-impact ones are cataloged for the future, so you can put your new custom software into production use quickly, what we call rapid application replacement.

Created with you
Our project managers will make sure that you’re part of the process every step of the way, regularly communicating project progress and working with our engagement managers to ensure strategic alignment of the project roadmap across all phases of the project.
