Experience

    Agile Coach & Scrum Master
    PUBLIC SECTOR
    June 2024 - December 2025 (1 year and 6 months)
    Groningen, Netherlands
    As an Agile Coach / Scrum Master, I have guided IT service teams in their development towards greater maturity. This resulted in independently executed sprints, honest feedback, and predictable outcomes. I have assisted numerous teams in this process.

    Below is an overview of the teams I have supported, my contributions, and the results achieved.

    IT Team Persons & Driver's Licenses (3 sub-teams):
    From a directionless team to a self-managing team.
    Focus: Guidance during team splitting, recruitment of new members, and removal of impediments.
    Result: Team members enjoy their team and work, self-facilitated rituals, and a mature Scrum team.

    IT Team Enforcement:
    Support in maintaining success during a period of uncertainty.
    Focus: Shared vision, recruitment, and openly and effectively addressing concerns.
    Result: Stable performance, high quality, and sustainable collaboration.

    Management Team Enforcement:
    Facilitating off-site workshops for vision formation, user story mapping, and departmental plans.
    Result: Shared vision, clear responsibilities, and prioritization in long-term projects.

    Facilitating management team sessions for Enforcement
    After facilitating multiple sessions such as User Story Mapping, Team Development Scans, and Team Building sessions at Service Team Enforcement, I was invited by their management team to support their sessions on creating a vision and subsequently a separate session on Root Cause Analysis. This resulted in a shared vision, strengthened team dynamics, and a concrete action plan.
    Personal development within the professional group

    Continuous improvement is a standard component. Therefore, we organize knowledge sessions lasting a few hours or half a day. We have covered the following knowledge sessions: Liberating Structures, Delivery Plans, Lean, Systemic Transition Management, Team Composition with Belbin, Dealing with Resistance, and Maximum Productivity in the 21st Century.
