Konzeption, Realisierung und Betreuung einer barrierefreien, gerä-teübergreifenden Web-Plattform mit nativer App-User-Experience

The contract comes into effect upon the award of the contract. The contract has an initial term until the end of the agreed service phase, which begins after acceptance and lasts for ten (10) years. The client has a unilateral option to extend the service phase twice, each by two (2) years.

The contract is divided into two main phases:

• Implementation phase (Umsetzungsphase): During this phase, the overall project is realized. This phase is further divided into five sub-phases, each concluding with a project milestone. The project completion is required by December 31, 2028, with a potential extension to March 31, 2029, currently under discussion.
• Phase 1 - Specification: A three-month phase for developing a detailed technical requirements document. The milestone for this phase is the final acceptance of the requirements document by the end of April 2027.
• Phase 2 - Market Research, Conception & UI/UX Design: This phase covers conceptual design, information architecture, and UI/UX design, with accompanying market research and tests starting from May 2027. The milestone for this phase is the approval of UI/UX designs and the interactive prototype by the end of August 2027.
• Phase 3 - Technical Development & Implementation: This phase involves frontend and backend development, accessibility implementation, and integration. It includes a six-month window for CMS content filling and migration.
• Phase 4 - Quality Assurance & Testing: This phase runs parallel to the end of Phase 3, focusing on general quality assurance, User Acceptance Testing, and official accessibility audits.
• Phase 5 - Launch & Go-Live: The final rollout phase, encompassing data migration, deployment to production, and DNS changes, culminating in the Go-Live. The implementation phase concludes with the overall acceptance of the services after the launch.
• Service phase (Servicephase): This phase begins after the acceptance of the web platform and focuses on providing services to maintain the operational capability and reliability of the platform.

The core scope of work for this tender involves the conception, realization, and ongoing support of an accessible, cross-device web platform with a native app user experience for Dresdner Verkehrsbetriebe AG.

The Statement of Work summary includes:

• Implementation Phase: This phase is divided into five sub-phases, each concluding with a project milestone.
• Phase 1 - Specification: Conversion of the existing requirements specification (Lastenheft) into a detailed technical specification (Gesamtpflichtenheft) that forms the binding contractual basis for subsequent phases.
• Phase 2 - Market Research, Conception & UI/UX Design: Encompasses technical conception, definition of information architecture, full UI/UX design, and accompanying market research or user tests to optimize user paths and layouts.
• Phase 3 - Technical Development & Implementation: Includes frontend and backend development, barrier-free implementation according to BITV 2.0 standards, and integration of core components. This phase also covers CMS filling and content migration by DVB editorial staff over a six-month period.
• Phase 4 - Quality Assurance: Ensures the quality of the developed platform.
• Deliverables: The overall project defined in the requirements specification and other contract documents, including all services, components, tools, and aids necessary for the contractual use of the services, even if not explicitly listed.
