Purpose of Disclosure
TMG is taking the lead in promoting data-based and evidence-based visualization of policy decisions and effects within the Government of Digital Agency. As part of this, TMG is providing practical guidebooks and other materials so that government, public institutions, and private companies can efficiently develop easy-to-understand dashboards. By making data easily visible, we aim to establish a correct common understanding among many stakeholders, improve the quality of decision-making, and lead to better actions.
The Implementation Guidebook was compiled and systematized to reflect the opinions of Digital Agency and experts in the private sector on dashboards and data-visualization, in addition to the knowledge gained in developing the Policy Data-Dashboard , which has been implemented in government officials.
It is aimed at all people, regardless of government or public institution employees, private sector or individuals, who want to use data and promote services but are unsure about how to use data appropriately.
Features of the Practical Guidebook
Dashboard Quality and Efficiency Process
It introduces the process for improving and enhancing QCD (Quality, Cost, Delivery), including sorting out the requirements for the dashboard and building a consensus with project stakeholders through the prototype.
A representation of information that contributes to the viewer's behavior or decision making
It introduces information expressions (layout, graph expression, etc.) and Do's (desirable expression) / Dont's (undesirable expression) that are necessary to encourage people to make decisions and change their behavior, such as expressions that allow the viewer to know what they want to know and do not cause misunderstanding.
Characteristics of the chart library
Grid system for creating an organized layout
To help anyone organize and arrange (layout) charts, we provide a grid system that serves as a basis for layout. You can create a dashboard with an easy-to-read layout by simply arranging charts to fit the grid.
Sample graphs with text, graph size, color, etc.
Sample graphs (bar graphs, line graphs, pie graphs, etc.) are provided with text and graph sizes, colors, etc., which can be used to improve work efficiency.
