1. business demand research
1) extract key indicators according to business scenarios
Key indicators are some general words, which are the general name of a group or a series of data. Generally, an indicator occupies an area on the big-screen dashboard. Therefore, through the definition of key indicators, we can know what content will be displayed on the big-screen dashboard and how many blocks the dashboard will be divided into.
After determining the key indicators, the priority of each indicator (primary, secondary and thirdary) is determined according to the business requirements.
primary: reflecting the core business content
secondary: used to further elaborate the main indicators
thirdary：supplementary information on Main Indicators
Examples are as follows:
2) define the dimension of indicator analysis
The data of the same index has different results from different dimensions.
Comparison: what are the differences between the data and what are the main aspects of the differences
Distribution category: what range and law are the data in the index mainly concentrated in
Proportion category: what are the components of the data in the indicator and what is the proportion of each component
Association class: correlation between data
also like Process, Map category, Interval class, Time class, Trends and etc.
3) determine the type of visualization chart
When a certain data relation type is determined, the corresponding charts and usage suggestions can be found according to the usage scenarios of the data, and the selection can be made among them.
Take a shopping mall data as an example
2. hardware research
Whether the big-screen dashboard has been purchased, the resolution of the big-screen dashboard, the resolution output supported by the big-screen dashboard graphics card, whether the graphics card supports the custom resolution, and the resolution supported by the HDMI line.
Understand the resolution of physical big-screen dashboard and determine the size of design draft.
3. data quality survey
Data source (data entry or not), data update cycle
| Data | Example |
|---|---|
| Data source | data entry, database |
| Data unit | unit, decimal place |
| Data update frequency | real time, quasi real time |
II. Prototype design
| Output |
|---|
| Index layout |
| According to the layout of good content landing into a prototype (Demo) |
1. big-screen dashboard index layout
Typesetting according to the business indicators set before:
Primary: the core business indicators are arranged in the middle, occupying a large area, and most of them are maps with rich dynamic effects
Secondary: secondary indicators are located on both sides of the screen, mostly for various charts
Thirdary: the content of auxiliary analysis can be displayed by drilling linkage and carousel
Generally, the related indicators are adjacent or close to each other, and the indicators with similar chart types are put together, which can reduce the cognitive burden of the viewer and improve the efficiency of information transmission.
2. output big-screen dashboard prototype demo
According to the layout landing into a prototype demo
III. Visual design
1. Define design style
First of all, consider the report positioning, user groups, company brand, audience age and other aspects.
According to the above report requirements, we can get keywords about report collocation. Then choose the appropriate color scheme according to the keywords.
2. Make UI effect diagram according to demo
According to the defined "design style" and "big-screen dashboard prototype demo", the reasonable visual design is carried out.
3. Effect drawing landing
Output cut.
4. beautify demo
Further beautify according to the renderings.
IV. big-screen dashboard debugging
1. Visual test
Whether the key visual elements, font size, page dynamic effect, graphics and charts are displayed as expected, whether there is deformation, dislocation, etc.
2. Performance and data testing
Whether the graphics and charts animation is smooth, whether the data loading and refreshing are abnormal, whether the page display is collapsed and stuck for a long time, and whether the background control system can switch the front-end page display normally.
V. Online operation
Screen out problem
Play cycle
