The work on the agreement aims to define the agenda of the meeting by listing the themes, objectives and themes on which the client wishes to focus, as well as the time allocated to each item. Structured or managed by contracts and agreements, accompanied by coaching, all client actions offer many operational indicators for possible improvement and development. By working with a coach, fuelled by a contract-making process, the client gradually develops a powerful performance-based modus operandi, centered on consistent and sustainable measurable results. While the contracting process is extremely crucial to supporting clients on their path to success during a coaching relationship, professional contracting skills also offer their clients an operational key to ensure success in all their future personal and operational efforts. During a coaching relationship lasting several months, the client is often confronted with new and sometimes unexpected topics that may or may not be in accordance with the original contract. At the beginning of each coaching or session session, it is therefore useful for the coach as well as for the client to “achieve the initial contract with “mini” contracts in the medium or short term and operational or agreements focused on emerging problems. Normally, these adaptations respect the main orientation of the original contract and redirect the coaching work towards more concrete or practical, emerging dimensions that were previously unpredictable. Beyond this first contract, which helps to specify the frame of reference of the coaching profession in relation to a client, the concept of contract is also a ubiquitous ability that is constantly implemented in many other subtle ways, at each stage of the journey during a coaching process. These other contractual skills in a coaching process can be considered “mini-contracts” or coach-client agreements. Coaching is a business relationship and justifies explicit agreements on borders, expectations and rights and obligations on both sides. The “disagree” option does not recognize the professional nature of coaching. The complexity of these triangular or polygonal contracts has long employed consultants, coaches and other professionals in relational or therapeutic contexts.
