In a paper1 published in CoDesign I introduce Layered Scenario Mapping, a mapping technique we developed in the Ulstein Bridge Concept project to address issues we had with coping with vast amounts of data from field research. The technique was developed to meet the needs we faced when designing a ship’s bridge, however, it may also prove valuable when designing for other contexts where the spatial and/or temporal dimensions are of importance. A guide enabling others to use the technique is available online.

Representing outputs from field research

A range of techniques for representing field research exists in design, including scenarios2, task analyses3, contextmapping4, customer journey maps, work models5 and many more. We found, however, that none of the existing techniques catered for our needs of getting an overview and details at the same time. Some of the techniques provided the detail, but lacked the context (e.g. task analysis). Others provided contextual insights, but lacked the necessary level of detail (e.g. contextmapping). We developed Layered Scenario Mapping for three reasons:

The map

Layered Scenario Mapping is a systemic design method aimed at helping designers understand the system they design for. The resulting map represents this system. Our map layout consists of overview information to the left and detailed information to the right.

The overview provides the reader with a frame of reference to use when deciphering the detailed information. In our map the overview includes a descriptive title, a visual presentation of the ship’s technical specifications, a description of the scene and introduction to the scenario, a presentation of the actors involved in the scenario, a written scenario story, and document information.

The detailed information is presented using a ‘timeline matrix’, with a step-by-step description of what goes on and key information related to each step. In our map the following is included:

Our experiences

We found that the map made it easier to make use of data from different sources. The way the data had been filtered, sorted, and put into a framework made the data more accessible and easier to share among the team. The description of what happens in the timeline matrix was the most-used part of the map, and the visual elements were particularly important in gaining a broader understanding of the scenario.

We used the map individually when developing design ideas and in collaborative sessions to discuss the appropriateness of ideas. The map invited comments, corrections, and clarifying questions, and thus facilitated mutual knowledge development. The map became a ‘boundary object’6 that we used internally within the project team, and also in communication with users and other stakeholders. For an in-depth discussion on our experiences with the map and a review of its appropriateness, see the CoDesign paper.

Further developments

Layered Scenario Mapping can be developed further, in many directions. The content of the map could be elaborated upon and expanded. As an example, we mapped out the scenario from the deck officers perspective only and believe we could have gained broader insight if we had also mapped out the scenario from the perspectives of several actors. Also, due to limited time, we made a paper-based map only. A digitised version could ease sharing and exploring the digital material collected during field studies.

The guide describing the technique is not intended as a definitive recipe, but rather meant as a useful starting point for others who would like to do their own Layered Scenario Mapping. I encourage others to develop the technique further!
