Mixed-style legal business mediator. Manon Schonewille uses an outcome-focused and eclectic or varied style of mediation that is adapted to the parties needs particularly in cultural disputes. Manon generally ‘mediates the process’ between parties and legal counsel first to support them in designing the appropriate process before the mediation starts. During the mediation she clearly manages the process aspects and uses a varied approach regarding the substantive issues depending on the topic, dispute and needs of the parties involved. She has superior communication skills and quickly establishes a trust-based working relationship with the participants. She uses her creative mediation style to guide parties to find new solutions and reach a sustainable outcome. She is a well prepared mediator and negotiator, that quickly builds rapport and with attention for details without losing sight of the big picture. As a legal mediator usually a facilitative style regarding the substantive aspects is used at the outset. When necessary further on in the mediation process or when desired by the parties a more evaluative approach may be applied. Emphasis is put on discovering mutualities, developing creative solutions and finding ways to expand the pie. Besides this, the implementation stage and 'workability' of the mediation outcome is in the center of attention. A well prepared mediator, with attention for details without losing sight of the big picture.
