While contracts can serve as a means to sanction breach and provide a winning argument in court, we believe that they should not be seen "primarily as a source of trouble and disputation". 2 This is a fundamental premise of the work of Louis M. Brown (1950, 3), known as the Father of Preventive Law. While in curative law it is essential for lawyers to predict what a court will do, in Preventive Law it is essential to predict what people will do. People are the focus of this chapter: those in charge of planning, negotiating, implementing or monitoring contracts, such as, for example, proposal, contract, commercial, sales, procurement, and project managers. Building on what is known as the Proactive/Preventive Law (PPL) 3 approach and on insights from the field of information design, 4 our work is geared towards helping people use contracts to achieve their business goals and prevent unnecessary problems.It follows that, in order to work well, contracts can no longer simply be drafted by lawyers for lawyers. Instead, we argue that the concept of contract drafting should be replaced by that of contract design, where strategic choices about the drivers and goals of collaboration merge with business and legal knowledge about how to maximize the chances of success and minimize risks and disputes, all wrapped up in people-centered communications to ensure that the contract can actually be implemented within the allotted time, with the resources that have been allocated, and within budget. Contract design is not only a matter of selecting the right content, words or clauses. It is also a matter of making sure the message is understood. In this chapter, we concentrate on the communicative aspects of contracts, in particular on the relatively new stream of research and practice that proposes visual communication as a way to enhance contract clarity and ease of use (e.g., Haapio 2013a; 2013b; IACCM 2016 5 ; Passera & Haapio, 2011). To understand the diverse visual practices and approaches in this emerging field, we propose a categorization based on design patterns. Patterns can be defined as reusable models of a solution to frequently occurring 2 According to Macneil and Gudel (2001, vii-viii), "[o]nly lawyers and other trouble-oriented folk look on contracts primarily as a source of trouble and disputation, rather than a way of getting things done." 3 Traditionally, the focus in the legal field has been on the past, mainly on failures and how to react to them through legal proceedings, remedies, sanctions, punishment, fines, and so on. Preventive Law promotes a different approach: one where the focus is on the future and on using the law and legal skills to prevent disputes and eliminate causes of problems (Barton, 2007). Proactive Law adds a focus to achieving positive goals and value. Together, PPL can harness tools toward smoother operations and successful outcomes (Haapio & Barton, forthcoming). 4 Information design is a discipline concerned with displaying information in ways that support effective and efficient u...
