Project Planning
A complete understanding of your requirements, goals & business drivers, informing better project outcomes.
When we engage in project planning, we take the time and care to dig deep into not only your software design requirements but also your business structure, audiences served, users, and more. We ask a lot of questions and undertake thorough discovery, working hand-in-hand with your team to ensure that the project scope is aligned with your business objectives. This approach mitigates risks and identifies any discrepancies between the current state of your systems, processes, and desired outcomes.
Essential deliverables from project planning work include a completed gap analysis, a total project cost estimate, and a detailed project roadmap. Whether you decide to stick with PSI to efficiently and collaboratively work through the entire software development lifecycle, the actionable master plan we produce for your custom software development project provides transparency and sets clear expectations for both the engineering team and your stakeholders.
Requirements & Design
With project plan documentation serving as a base, our team of skilled software engineers undertakes the transformation of your product needs into a clear and understandable software architecture and design, including cybersecurity planning that’s ready for implementation. This critical early project work sets everything up for success. If requirements and design work are thoroughly and thoughtfully completed, later project stages will be “smooth sailing.” Trust us, you want to get this phase right.
Project design deliverables include everything needed to save time and effort later, such as in testing and post-development verification. PSI provides our clients with comprehensive software design documentation, risk analysis, failure mode effects and criticality analysis (FMECA), and design review to make everything easily understood by all involved.
Your project roadmap becomes a software architecture to shape successful development.
Development & Integration
Precision coding to implement your system as designed… with updates at every stage.
This is where your software really begins to takes shape—when our engineers bring your software design to life with skillful coding and engineering work. It’s a seamless process when requirements are done right, though our team can jump in here to create a secure and robust product based on the existing software design documentation you have in hand.
Development is a complex process, and we keep you apprised of progress with updates at regular intervals so you can stay in the know as we work through implementation and integration of custom-built source code. You will receive sprint releases, documentation updates, and a software test plan that can be submitted to regulatory bodies.
Testing & Verification
While testing and verification are naturally ongoing throughout the development stage of any software project, comprehensive testing is also critical once development is complete. Here, our software engineers test against a prescribed test plan, ensure that your software seamlessly integrates into your system’s hardware, and confirm everything meets the agreed software requirements.
As our valued client, you own all project source code and documentation after testing, and you will also be provided with a test execution report as the project crosses the finish line. Full transparency throughout our work together means you have written proof confirming we built your system to spec, just as the software requirements described.
We make sure your software does exactly what it’s supposed to—integrating with your hardware, meeting every requirement, and standing up to rigorous testing.
Maintenance & Support
We're here to keep your system running its best post-release with updates, optimization & enhancements.
At PSI, we stand behind every software development project we undertake, and our software engineers are ready to support your system post-release with maintenance updates, feature additions, system optimization, and enhancements on any platform.
Have software for a system that our engineers didn’t build? We are also capable as a response team to help resolve issues and eliminate bugs. Don’t continue to suffer with undesirable behaviors in your existing software—our team can help with fixes and refinements.
