The Dutch Government seeks to prepare its country for a changing and uncertain future, but its civil servants often lack the right mindset and environment to do so. Various Governmental initiatives were started to solve this problem of ineptness; one of which is LEF – Future Center (LEF) which is part of Rijkswaterstaat (RWS).

LEF is a place where creativity and breakthroughs are facilitated in LEF sessions. Within a session, participants are guided, by a facilitator, into this non-governmental-like behavior, which could be called LEF Magic.

Main question

Because of the growing usage of data within LEF, data’s promising applications, and because RWS is the second biggest dataset owner of the Netherlands, the thesis focuses on data and Data Visualization as the domain to work in.

Main question: How can Data Visualization effectively use data to positively influence participants of LEF’s sessions?


Four research perspectives concerning the central question: context (focuses on the people and environment), product (focuses on product features and qualities), psychology (focuses on brain and group processes), and result (focuses on outcomes). Each research perspective has its own set of questions. These questions where than answered by a tailor-made research and design method called Observation, Research, Ideation, and Exercise (O.R.I.E.).

Main findings

As a result of the O.R.I.E. method, various opportunities and problems were identified. The biggest being that LEF participants lost information, motivation, and inspiration after a session and that there was little to no aftercare. Additionally, LEF was suffering from negative attitudes towards the LEF brand.

Produced product

A solution was designed called De Notulen, a new take on the concept of making minutes of a meeting and is meant as aftercare. Instead of only transcribing events that happen in a LEF session, De Notulen tries to record a myriad of LEF Session activities and turns it into several Data Visualizations. With the help of Data-Driven Narration techniques, De Notulen retells the story of a session in such a way that it helps with remembrance, inspiration, motivation, and brand attitude.


Prototype findings and a small user study suggest an increase in remembrance, inspiration, and motivation towards a session topic. However, the significance’s of these findings are low, due to the low amount of participants and a high chance of biases.

The thesis advises LEF to continue with De Notulen and do additional user studies with more participants and control for biases. Additionally, the thesis advises LEF to outsource most of the technical aspects.
