To successfully deliver software engineering-focused projects, PSI relies on 5 key development phases. Each phase incorporates additional levels of functionality, ultimately yielding a final product that meets all software requirements. PSI works diligently to integrate the following phases into our client’s product development lifecycle, ensuring software milestones sync up seamlessly with other engineering disciples i.e. hardware, mechanical, electrical.
SOFTWARE DEVELOPMENT PROCESS
WE TAKE A PHASE-BASED APPROACH TO EACH PROJECT
FASTER. MORE COST-EFFECTIVE. BETTER RELIABILITY.
If speed-to-market, cost, and overall software reliability are critical factors when selecting a software partner, consider PSI’s hybrid v-model process methodology. Essentially a requirements/design-based process, PSI engineers work through a traditional v-model that encourages flexibility in sprint deliveries, incorporating agile components to keep the project moving quickly.

HOW WE EXECUTE THE PROCESS
Each phase of the software development process can be modified for your exact needs. We walk through the development process by phase; however, allow flexibility in completing elements of each phase as it makes the most sense for your development schedule.
PLANNING
Understanding your requirements, goals, and business drivers to assess your starting point
DESIGN
Converting your product needs into a software architecture and design that can be understood by all and implemented by software engineers
DEVELOPMENT
Creating the code to implement your system as designed while incorporating necessary changes and keeping you in the know as the work progresses
TESTING
Ensuring that the system, as built, integrates into your system’s hardware and confirming it meets the agreed specifications
MAINTENANCE
Once you own the software, feel confident that it was designed with maintenance in mind. Manage it yourself or take advantage of PSI’s support services.
