Clients frequently tell us that the development process feels like a black box — they hand over requirements and money, and weeks or months later they receive software. We believe this opacity is one of the biggest problems in the industry. At OBI Systems, we have built our entire delivery methodology around transparency, client involvement, and predictability. Here is how it works.
Phase 1: Discovery and Scoping (1 to 2 Weeks)
Every project begins with a structured discovery phase. This is not a casual conversation — it is a focused engagement where we map your business processes, define user journeys, identify integrations, and establish the project scope. The output is a detailed project specification document that both parties agree on before development begins.
- Stakeholder interviews to understand business objectives and success criteria
- User journey mapping for each user type in the system
- Technical architecture proposal covering stack, infrastructure, and integrations
- Feature prioritisation using the MoSCoW framework (Must, Should, Could, Won't)
- Fixed-price quote based on the agreed specification
We charge for the discovery phase separately (typically 1,000 to 3,000 euros depending on project complexity). This ensures we invest proper time in understanding your needs — and gives you a specification document you can take to any vendor if you choose not to proceed with us.
Phase 2: Design (1 to 3 Weeks)
Before writing any code, we design the user interface and user experience. Depending on the project, this includes wireframes, interactive prototypes, and final visual designs. Clients review and approve designs at each stage. This catches misunderstandings early — when changing a design costs hours, not days of rework.
- Low-fidelity wireframes for layout and flow validation
- Interactive prototypes in Figma for user testing
- Final UI designs with component libraries for consistent implementation
- Design system documentation for future development consistency
Phase 3: Development (4 to 16 Weeks)
Development follows an agile methodology with two-week sprints. Each sprint has a defined scope, and at the end of each sprint the client receives a working demo of the features completed. This means you see real, working software every two weeks — not just status reports.
- Two-week sprint cycles with defined deliverables
- Bi-weekly demo sessions where the client tests working features
- Continuous integration and deployment — code is tested automatically with every commit
- Code reviews by senior developers on every pull request
- Shared project board (Jira, Linear, or similar) with real-time progress visibility
Phase 4: Quality Assurance (Continuous + Final)
Quality assurance is not a phase that happens after development — it runs continuously. Automated tests are written alongside the code. Manual testing covers user journeys, edge cases, and cross-browser or cross-device compatibility. Before delivery, we conduct a comprehensive final QA pass covering:
- Functional testing — every feature works as specified
- Performance testing — load times, server response, stress testing
- Security testing — vulnerability scanning, penetration testing for web applications
- Compatibility testing — browsers, devices, screen sizes
- Accessibility testing — WCAG compliance checks
- User acceptance testing (UAT) — client's team validates the system against requirements
Phase 5: Deployment and Launch
Deployment follows a structured checklist covering infrastructure provisioning, data migration, DNS configuration, SSL certificates, monitoring setup, and backup procedures. We deploy to a staging environment first for final client approval, then to production during a planned launch window. Post-launch, we monitor the system closely for 48 to 72 hours to catch any issues that only appear under real traffic.
Phase 6: Handover and Ongoing Support
Every project includes a handover package: technical documentation, user guides, access credentials, and a recorded training session. We provide a warranty period (typically 60 to 90 days) where we fix any bugs at no additional cost. After the warranty, clients can choose from our maintenance retainer packages for ongoing support, updates, and incremental improvements.
The Team Behind Your Project
A typical project team at OBI Systems includes a project manager (your single point of contact), one or more frontend developers, one or more backend developers, a UX/UI designer, and a QA engineer. For larger projects, we add a technical architect and a DevOps engineer. Every team member is an OBI Systems employee — we do not subcontract to freelancers.
Our ISO 9001 certified processes ensure that the quality of delivery does not depend on any single individual. If a team member is unavailable, the documented processes, code standards, and project knowledge base allow another team member to step in seamlessly.
