|
## The Four Questions
|
|||
|
|
|
|||
|
|
Every dashboard must answer:
|
|||
|
|
|
|||
|
|
| # | Question | Example |
|
|||
|
|
|---|----------|---------|
|
|||
|
|
| 1 | **What is happening?** | "Area score dropped to 87" |
|
|||
|
|
| 2 | **Where is it happening?** | "In Nacka municipality" |
|
|||
|
|
| 3 | **How serious is it?** | "Below threshold of 90" |
|
|||
|
|
| 4 | **What do I do now?** | "Inspect area" / "Order report" |
|
|||
|
|
|
|||
|
|
If any question is missing, the dashboard is not complete.
|
|||

## Information Hierarchy
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
LEVEL 1: Score
|
|||
|
|
(the single most important number)
|
|||
|
|
|
|||
|
|
LEVEL 2: Three most important observations
|
|||
|
|
(what changed, why it matters)
|
|||
|
|
|
|||
|
|
LEVEL 3: Map
|
|||
|
|
(where things are happening)
|
|||
|
|
|
|||
|
|
LEVEL 4: History
|
|||
|
|
(trends over time)
|
|||
|
|
|
|||
|
|
LEVEL 5: Details
|
|||
|
|
(drill-down for deeper analysis)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Not the reverse.
|
|||

## Decision Density
|
|||
|
|
|
|||
|
|
| Screen | Target Decisions | Notes |
|
|||
|
|
|--------|-----------------|-------|
|
|||
|
|
| Onboarding | 1 | "Should I join?" |
|
|||
|
|
| Marketplace | 1 | "Should I register?" |
|
|||
|
|
| Dashboard | 1–3 | "What do I act on?" |
|
|||
|
|
| Report | 1 | "Should I invest/repair?" |
|
|||
|
|
|
|||
|
|
If a dashboard tries to support ten decisions, it needs to be split or restructured.
|
|||
|
|
|
|||

|
## Not BI
|
|||
|
|
|
|||
|
|
Landvex is not BI.
|
|||
|
|
|
|||
|
|
**Not:** Tables, charts, widgets, KPIs.
|
|||
|
|
**But:** Reality → Understanding → Decision.
|
|||
|
|
|
|||
|
|
The dashboard helps the user make a decision, not consume statistics.
|
|||
|
|

|
## Verification
|
|||
|
|
|
|||
|
|
For every dashboard:
|
|||
|
|
- [ ] Can I understand the situation in 3 seconds?
|
|||
|
|
- [ ] What is today's most important decision?
|
|||
|
|
- [ ] Can I ignore 80% of the information?
|
|||
|
|
- [ ] Is there a primary CTA?
|
|||
|
|
- [ ] Does it answer: What, Where, How serious, What now?
