Engagement Models
Choose the right delivery model for your project stage
Overview
Different projects require different delivery models depending on uncertainty, speed, governance, and operational needs. ARIS Vietnam provides four engagement models covering the full lifecycle: validate → build → scale → operate.
| PoC/MVP QuickStart (4–6 weeks) | Dedicated Team (T&M / Lab) | Fixed Scope Delivery | Maintenance & SLA Pack | |
|---|---|---|---|---|
| Best for | Fast validation, de-risking | Continuous delivery, evolving roadmap | Predictable delivery with acceptance | Production stability and support |
| Scope stability | Low–Medium | Low–Medium | High | Medium–High |
| Budget predictability | Medium (range → refined) | Medium (capacity-based) | High | Medium–High (package-based) |
| Speed to start | Very fast | Fast | Medium | Fast–Medium |
| Governance & control | Medium | Medium–High (process-driven) | High (baseline + CR) | High (SLA + reporting) |
| Typical duration | 4–6 weeks | 3+ months | 2–6+ months | Ongoing |
Scope of Services
1) PoC / MVP QuickStart (4–6 weeks)
Deliver a working product slice + decision-ready outputs in 4–6 weeks.
Typical outcomes
- Demo-ready PoC/MVP
- Scope boundaries (in/out) + assumptions
- Key risks validated (integration, data, performance, AI/OCR)
- Phase 2 roadmap + budget range
2) Dedicated Team (T&M / Lab)
A stable delivery team with flexible scope, driven by backlog and priority.
Typical outcomes
- Sprint-based delivery + transparent reporting
- DoD (Definition of Done) + disciplined change management
- A team that accumulates domain knowledge over time
3) Fixed Scope Delivery
Predictable delivery when requirements and acceptance criteria are clear.
Typical outcomes
- Baseline scope + acceptance criteria
- Change control (CR) to prevent scope creep
- Quality gates to reduce late rework
4) Maintenance & SLA Pack
Operational support with SLA metrics, RCA, and continuous improvement.
Typical outcomes
- L1–L3 support (triage → investigation → fixes)
- SLA/Severity definitions + monthly reporting
- RCA + prevention actions, runbooks, monitoring options
How to choose (quick guide)
- High uncertainty / need fast validation → QuickStart (PoC/MVP)
- Continuous delivery / changing priorities → Dedicated Team (T&M/Lab)
- Stable scope / fixed acceptance → Fixed Scope Delivery
- Production support / response time targets → Maintenance & SLA Pack
Why ARIS Vietnam
Clear delivery governance: weekly reporting, decision logs, risk tracking
Flexible transitions: QuickStart → T&M/Lab → Fixed Scope modules → SLA operations
Engineering discipline: DoD, change control, quality gates when needed

Contact UsFrequently Asked Questions
Start with QuickStart to validate assumptions and reduce risk, then scale with T&M or Fixed Scope.
Yes. A common setup is Fixed Scope for stable modules + T&M for evolving areas + SLA for production support.
We enforce backlog discipline, DoD, weekly reporting, and change impact visibility.
When scope and acceptance criteria are testable and stable. If not, do QuickStart first.
We define testable acceptance criteria (Fixed Scope) or DoD (T&M) upfront and report against it.
Yes—if we align early on whether it's a throwaway PoC or a production-bound MVP.
A decision owner (PO), access to environments/data, and timely feedback/approvals.
Yes. We align cadence, channels, and response expectations during onboarding.
