We delivered two information design workshops for the legal department of the Finnish Centre for Pensions, with participants from both legal and other professional backgrounds. In the sessions, we applied the principles of legal design thinking to the Finnish Centre for Pensions’ field of operation and background materials, also utilising AI as a design tool. The participants found the tailored training highly useful and commended the trainers for their in-depth familiarisation with the Centre’s opinion drafting process and operating environment. As a result of the workshops, our experts proposed a new structural and linguistic model for the legal department of the Finnish Centre for Pensions for drafting opinions and guidelines.

We drafted new Codes of Ethics for SATO to use internally and with business partners. The client wanted to get concise and legally up-to-date Codes that are easy to understand and look fresh. We drafted completely new Codes, designed a clear structure for them and designed and implemented their layout. We made separate Codes of Ethics for internal use and for business partners in order to meet the exact tone and style suitable for both end user groups. We also made English translations of the Codes of Ethics. The end product was practical and interactive PDF instructions that are consistent with the client’s visual style. Client insight and taking the target group’s needs into account are some of the main principles of legal design. The client’s wishes also focused on the end users of the Code of Ethics, i.e. the company’s employees and business partners. In this project, efficient project management and an open line of communication helped us understand the wishes of the client company and deliver an end product with which the client was very happy. Active dialogue with the client was an important quality factor in this agile and iterative project. In the first phase we provided the client with a prototype and then continued the design work based on the comments we received. The appearance of the final product was designed in accordance with the client’s graphical guidelines. SATO Corporation is an expert in sustainable rental housing and one of Finland’s largest rental housing providers. SATO owns around 25,000 rental homes in the Helsinki Metropolitan Area, Tampere and Turku. Approximately 45,000 residents live in SATOhomes. The project involved experts in legal design, linguistics and graphic design, and members of our Legal Tech team.
