Summary – Without a well-framed requirements specification, IT projects risk budget overruns, extended timelines and non-compliance with Swiss sovereignty and interoperability requirements. By combining strategic workshops, IT landscape mapping and a MoSCoW/MVP approach, you formalise vision, testable user stories, business KPIs and GDPR/nLPD/ISO 27001 constraints into a concrete action plan. Solution: agile governance with validated milestones, automated testing and continuous oversight to deploy quickly, correctly and without drift.
Developing an effective IT requirements specification is not just about compiling a wish list. It’s a decision-making tool that brings together senior management, business teams, and the IT department around a prioritized scope, measurable KPIs, and optimal security and compliance constraints.
In Switzerland, where data sovereignty and integration with the existing ecosystem are paramount, this document must lead to a concrete action plan ready for the build phase. Discover how to frame your project quickly and precisely, then execute without slippage through strategic workshops, a clear IT system mapping, testable user stories, and an agile governance model.
Defining Scope and Structuring Priorities
An IT requirements specification must clarify the strategic vision and use cases before listing features. It prioritizes a MoSCoW/MVP approach to align stakeholders on a relevant and immediately actionable scope.
Aligning Strategic Vision and Business Use Cases
The first step is to formalize the project vision through concrete use cases that describe interactions between users and the system. Each use case demonstrates a specific business value, whether it’s streamlining an internal process or enhancing the customer experience. This approach captures executives’ attention and justifies the expected return on investment.
In a recent construction sector project, the IT department structured the vision around a site progress tracking portal. The use cases highlighted a 40% reduction in approval times, demonstrating a tangible impact on site management.
By detailing each scenario, stakeholders identify key interactions and existing friction points. These insights feed into the requirements specification and ensure the solution addresses real needs rather than an unprioritized feature list.
Prioritization with MoSCoW and Defining the MVP
The MoSCoW method segments requirements into Must, Should, Could, and Won’t to prevent scope creep. This classification surfaces critical features and those that can be postponed. The IT department, business teams, and leadership then agree on a minimum viable product (MVP) for the launch phase.
An e-commerce SME defined the MVP as a shipment tracking module and a management dashboard. Features classified as Should or Could were scheduled for later releases. This decision enabled a first version to go live in three months without exceeding the budget.
This method limits deviation risks and makes the project more agile. Development focuses first on high-impact issues, while secondary enhancements are planned on the IT roadmap.
Defining Business KPIs and Security Constraints
Performance indicators are essential for measuring project success and guiding its evolution. They can include user satisfaction rates, reduced processing times, or increased revenue from new services. Each KPI must be clearly defined, measurable, and tied to a use case.
At the same time, compliance requirements such as GDPR, the Swiss Federal Act on Data Protection (FADP), and ISO 27001 certification are formalized in the specification. Data sovereignty stipulations are detailed: storage location, access rights, and encryption protocols.
These documented commitments protect the organization from legal and security risks. They also ensure alignment with Swiss best practices for managing sensitive data.
Structuring the Scoping Workshop and IT System Mapping
The scoping workshop unites stakeholders around a shared culture and a common ROI vision. Mapping systems and interfaces sheds light on dependencies and facilitates integration with the existing IT landscape.
Running the Strategic Workshop on Vision and ROI
The scoping workshop brings together the IT department, business leaders, and executive management to validate objectives, use cases, and the value model. Each participant presents their priorities, enabling operational and financial stakes to be balanced.
This session produces consensus on the roadmap and a short- and mid-term action plan. Estimated gains are quantified, ensuring a shared understanding of expected returns.
The collaborative format strengthens project ownership and minimizes later criticism. It also provides a solid foundation for drafting the requirements specification by ensuring all parties are engaged.
Mapping the IT System and Identifying Key Interfaces
A detailed map of the existing IT system identifies applications, databases, and data exchange flows. This overview reveals critical dependencies and integration points required for the new solution.
In a healthcare project, more than fifteen interfaces were cataloged between the ERP, CRM, and a specialized business application. The mapping exposed bottlenecks and enabled phased testing for each integration point, preventing startup delays.
This proactive analysis supports a gradual migration plan and end-to-end testing, significantly reducing the risk of production service interruptions.
Engaging Operational Teams and Defining Governance
Project governance is established during the scoping workshop. Roles and responsibilities are clarified: product owner, scrum master, architect, business liaisons. This agile model ensures rapid decision-making and smooth communication.
Regular synchronization points (daily stand-ups, sprint reviews) are scheduled from the outset to maintain alignment and adjust scope as needed. The iterative approach avoids the “waterfall tunnel” effect and provides continuous visibility into progress.
This collective commitment from the scoping phase builds trust and lays a solid foundation for execution without drift.

Writing Testable User Stories and Acceptance Criteria
User stories organize functional requirements into clear scenarios, promoting automated test creation. Acceptance criteria turn each story into a verifiable deliverable, ensuring quality and compliance.
Developing User Stories with a User-Centric Focus
Each user story follows the format “As a…, I want to…, so that…”. This structure directs development toward business value rather than a technical to-do list. It also facilitates prioritization and breakdown into concrete tasks.
The story-driven approach ensures a shared understanding of the requirement and fosters collaboration between developers, testers, and business teams, reducing the risk of misunderstandings.
Defining Precise Acceptance Criteria
Acceptance criteria list the conditions that must be met for a user story to be considered done. They cover functional aspects, performance, security, and compliance. Each criterion corresponds to a unit, integration, or end-to-end test.
This level of detail protects the project from functional drift and ensures that only compliant deliverables are deployed to production.
Ensuring Traceability and Test Automation
Each user story and its criteria are tracked in an agile project management tool, ensuring backlog transparency. Automated tests are linked to acceptance criteria to generate coverage and regression reports.
This integration between backlog management and CI/CD pipelines provides rapid feedback loops, which are essential for maintaining quality and accelerating delivery cycles.
Implementing an Agile Contract Model and Continuous Governance
The agile contract is structured around milestones based on tested and validated deliverables, with formalized acceptance criteria. Continuous governance through regular reviews keeps alignment and anticipates necessary adjustments.
Organizing Milestones and Validated Deliverables
The contractual schedule is organized into sprints or delivery phases, each culminating in a testable deliverable. Milestones are tied to staged payments, aligning financial incentives with quality and actual progress.
This model avoids rigid fixed-price commitments and allows adaptation based on user feedback and evolving needs.
Detailing Agile Governance Clauses
The contract includes rituals: monthly steering meetings, sprint reviews, and executive committees. Each meeting produces a formal report documenting decisions, risks, and action plans.
These clauses also outline the change management process, defining validation procedures and financial impact assessments. This transparency protects both parties from budgetary or functional overruns.
Contractualizing agile governance ensures a sustainable collaboration, builds trust, and maintains the demand for tangible results at each stage.
Monitoring Deliverables, Managing Risks, and Adjusting
Continuous oversight relies on key indicators: functional progress, deliverable quality, schedule adherence, and budget burn. These metrics are shared during steering committee meetings to inform decisions.
In a complex ERP/CRM integration project, weekly monitoring of indicators detected an early deviation on a critical interface. A remediation plan was launched immediately, limiting the impact on the overall schedule.
This proactive support anticipates risks and adjusts delivery cadence to ensure controlled execution that honors the initial commitments.
