About the Mission

Description of the context The Directorate General for Persons with Disabilities (DG HAN) is a directorate within the Federal Public Service Social Security and contributes to an inclusive society. Their goal is to increase the autonomy of persons with disabilities by assessing the impact of disability on daily life and compensating through services. They support people with disabilities by providing allowances and other rights, such as financial support, parking tickets and certificates for applying for benefits from other services. They are also committed to making these rights accessible to people with disabilities and granting them fairly, so that everyone has the best experience when exercising them. Currently, approximately 600,000 people are recognized as having a disability, of which 240,000 receive an income replacement allowance and/or an integration allowance every month. 514,000 parking tickets are in circulation. In 2024, 160,722 disability assessments were conducted. In 2019, the Council of Ministers decided that DG HAN could replace the existing back office application (TETRA) with a new, modern application (TRIA). The transition to a new application is crucial because TETRA is outdated and uses technologies that are no longer supported. At the same time, DG HAN must continue to fulfill its mission towards citizens. The TRIA program is extensive and therefore consists of various sub-projects. The TRIA program is further supported by other teams within the FPS SZ ICT and DG HAN. The application in this assignment concerns the BI team of DG HAN. We are looking for 1 profile for this team: 1. A senior technical analyst/developer The assignment takes place in an Agile context within a TRIA scrum team of approximately twenty people (functional analysts, architects, developers, UX designers). Description of the assignment The BI team plays an essential role within DG HAN. In addition to defining and maintaining operational management reports, the knowledge and skills of the BI team are also used within the TRIA program where possible and appropriate. The intention is that a number of specific ‘fluxes’ will be developed within this assignment and made available to the TRIA team and the TRIA application. Strong collaboration with the TRIA team is therefore essential. For this we are looking for an additional profile, with the necessary knowledge and experience, who will be part of the existing BI team. Being able to quickly familiarize yourself with and integrate into the team’s working methods is expected. Given the complexity and urgency of the program, the interrelationship with internal and external modules and its specific subject matter, a person is chosen who has demonstrable experience with the context of social security systems and the development and maintenance of ‘fluxes’ within government agencies, and more specifically those of which DG HAN is regarded as an ‘authentic source’, but also the fluxes that DG HAN must use. Collaboration We expect the supplier to have a structured and transparent working method when carrying out the order. It is essential for us that the assignment is carried out in a planned and manageable manner, with an explicit focus on achieving concrete results within the expected time limits. The supplier is asked to work according to an end-to-end approach, with working functionalities being delivered in every sprint (2 weeks). By means of short feedback loops, the end product must be continuously tailored to the wishes and needs of the business and of the other teams responsible for the business logic (e.g. TRIA Handi2Pay or myHandicap Portaal). This allows us to flexibly adjust priorities based on evolving insight or changing circumstances. Close and transparent cooperation between client and supplier is crucial throughout the entire process. This involvement enables us to respond quickly to changes and ensures maximum agility in the project progress. Formal milestones and changes in the project – such as scope adjustments, phase completions, architecture changes or production releases – can take place after prior coordination with relevant stakeholders.For us, transparency and open communication are preconditions for successful implementation. Timely and honest dialogue makes it possible to identify bottlenecks early and tackle them effectively.
