An Increment (Product Increment) is the usable, integrated work result of an iteration that builds on all previous increments. It represents the sum of all “Done” Product Backlog items since the beginning of the product and must be in a potentially releasable state.
In Scrum, at least one Increment is created per Sprint. In SAFe, Team Increments are created per iteration; at the ART level, these integrate into a System Increment. Over the course of a Program Increment (PI) (typically 8–12 weeks), an ART delivers incremental value in the form of working software or systems, demonstrated in System Demos and during Inspect & Adapt.
Practical Relevanc
- Value focus: Every Increment delivers tangible customer value and reduces “big-bang risks.”
- Built-in quality: A strict Definition of Done enforces integrated, tested, and documented results – no hidden work.
- Faster learning: Regular user validation enables early feedback and adaptation.
- Transparency & control: Increments act as hard inspection points for progress, risk, and viability.
- Scalability: In SAFe, consistent cadence aligns teams and minimizes late integration surprises.
Real-World Examples
Scrum – Digital Customer Portal
A utility provider rebuilt its self-service portal. Every two weeks, the team delivered a working Increment with end-to-end functionality.
Artifact: Team DoD with ≥80% test coverage, E2E tests green, security scans without critical findings, release notes updated.
SAFe/ART – Embedded Systems
An ART with six teams integrated results every two weeks on a hardware test bench.
Artifact: ART-level checklist: Safety suite green, telemetry active, recovery path validated.
SAFe – Platform & Product
A platform ART delivered APIs, while a product ART integrated workflows.
Artifact: Contract test skeleton using OpenAPI specifications.
Regulated Domain (Finance/Healthcare)
Compliance deliverables became part of every Increment.
Artifact: Updated DPIA register, audit-trail events, IAM permissions, security test reports.
Transformation Increment (TI)
Organizational change initiatives were structured in quarterly Transformation Increments.
Artifact: TI review board including goals, baselines, results, and next actions.
Hardware Development (Automotive/MedTech/Industry)
Hardware teams also deliver Increments – functional prototypes or assemblies, integrated and tested each iteration.
Artifact: Hardware DoD including built prototype, interfaces validated, stress-tested, compliance evidence (e.g., FMEA), PDM data versioned.
Other Examples:
- Automotive: ECU prototypes with firmware every 3 weeks, tested in HiL (Hardware-in-the-Loop).
- MedTech: Iterative increments of diagnostic devices, validated against ISO 13485.
- Industrial robotics: Stepwise functional assemblies (e.g., motor control, sensors) integrated each iteration.
Implementing in Practice
- Definition of Done: Teams define verifiable criteria; ART-level DoDs include integration, compliance, and operability.
- Vertical slices: Deliver end-to-end functionality, not technical layers.
- CI/CD pipelines: Every commit potentially releasable, automation extended to hardware simulations and test benches.
- System integration: Regular System Demos prevent “big bang” integrations.
- Hardware increments: Define clear prototype stages (Lab Sample → Proto A → Proto B → Pilot series).
- Operational readiness: Monitoring, alerting, and runbooks included in the DoD.
Anti-Patterns
- Demo-ware instead of DoD: Only UIs or mockups shown; no tests, documentation, or operability. Attractive in demos but worthless in production.
- Layer-only increments: Teams deliver “just database” or “just frontend.” No customer value, integration risks pushed to the end.
- Late large-scale integration: All components integrated at PI-end; results in defect avalanches, stress, and poor quality.
- Weak or negotiable DoD: If “Done” is vague or inconsistent across teams, technical debt piles up and integration fails.
- Overloaded increments: Too many backlog items in one iteration; context switching, defects, delays.
- No system demos: Teams work in silos; integrated product stays invisible too long.
- Missing NFRs: Performance, security, and operability not part of the DoD → Increment is functional but not usable or compliant.
- Simulation-only in hardware: CAD models or mock-ups without physical validation; risks hidden until it’s too late.
- Output over outcome: Teams deliver “finished stories” but do not validate business value; Increment loses meaning as a value measure.
CALADE Perspective
At CALADE, we see Increments as rhythm-makers for value, learning, and quality – in software, hardware, and transformation initiatives alike. With Transformation Increments (TI), we deliver visible results every quarter (policies, processes, pilot projects), make progress measurable, and enable adaptive steering. In hardware contexts, we emphasize iterative prototyping with a clear DoD, ensuring risks surface early and disciplines (mechanics, electronics, software, compliance) collaborate effectively.
