How Change Is Tracked
engage.re captures change from three sources. Each source can have attributes — measurable properties that change over time.
Three Sources of Change
Users
People.
Users have attributes that describe their state: employment status, housing situation, health metrics, skills, qualifications.
- employed: no → yes
- housing: temporary → stable
- qualification: none → NVQ Level 2
- wellbeing score: 4 → 7
When a user's attribute changes, they can be asked what helped — via the contribution slider.
Entities
Anything that is NOT a human.
This is deliberately broad. An entity is any trackable thing in the world that has measurable properties.
- Air quality sensor
- Community fund
- Social housing unit
- Park or green space
- Vehicle or fleet
- Dataset or registry
- Tree or woodland
- Building or venue
- Piece of equipment
- Plot of land
- PM2.5: 25 → 18 μg/m³
- Fund balance: £0 → £50,000
- Occupancy: vacant → occupied
- Tree count: 150 → 175
Entity attribution is typically automatic — based on who owns or manages the entity.
Measurables
Initiatives themselves.
Teams, projects, strategies, and issue spaces can have their own tracked attributes — properties of the initiative rather than its participants.
- Member count: 150 → 175
- Budget spent: £10k → £25k
- Partnerships: 3 → 5
- Sessions delivered: 0 → 42
Upcoming Attribute tracking for measurables is not yet implemented.
Types of Change
Regardless of source, tracked changes fit these persistent patterns:
How Attribution Works
| Source | How Credit Is Assigned |
|---|---|
| Users | The user is prompted: "What helped you achieve this?" — they distribute credit via the contribution slider |
| Entities | Automatic The initiative that owns or manages the entity gets credit for changes |
| Measurables | Direct The measurable's own attributes change (no external attribution needed) |
For more on how credit flows up hierarchies (Team → Project → Strategy → Issue Space) and across geography (Hackney → London → UK → Global), see Attribution .
