Value Discovery & Mission Strategy

First, we’ll sit down and discuss your software project in depth. Once we understand your values and objectives, your users, and case scenarios, we’ll create custom user personas and begin establishing requirements. We will then draft user stories to set our development process in motion.

App Design & Information Architecture

When our UX and UI design team has a thorough understanding of the task at hand, we’ll begin creating detailed information architecture diagrams that outline how users will interact with your web or mobile application. These details serve as the roadmap for wireframing, high level interactions, page elements, and hierarchy. Then, wireframes set the foundation to test via clickable prototype. We’ll then finalize your desired aesthetic with pixel-perfect comps.

Agile Development & QA Process

With clear tasks assigned, we begin to build your app. Each morning, we hold a stand-up meeting to report what has been accomplished, what we intend to accomplish by the next meeting, and anything that stands in our way. This process keeps the entire team in the loop and any potential impediments on our radar.

Final UAT + Product Launch

Before we launch your app, we run it through a final User Acceptance Testing process for quality assurance. We perform end-to-end performance testing with real or simulated users in order to ensure the complete system achieves your business goals. Once our QA process team gives us the green light, your app is ready for takeoff!
