SOW-BASED ENGAGEMENTS

Outcome-priced delivery. Defined scope. Real accountability.

Structured Statement-of-Work engagements for cloud migrations, ERP implementations, application modernization, data programs, and managed services — with the scope, the timeline, and the success criteria written into the contract.

SOW Engagements
THE PREMISE

When the work is well-defined, the contract should be too.

Time-and-materials staffing is the right answer for some problems and the wrong answer for many others. When the scope is clear, the target architecture is set, and the success criteria can be written down — billing by the hour shifts every incentive in the wrong direction. SOW-based engagements flip that. The vendor wears the timeline risk. The price is set against the outcome. The team rotates around the deliverable, not the calendar.

Exolios SOW engagements are built specifically for the work where the boundaries are knowable: a cloud migration with a clear estate, an ERP implementation with a defined module footprint, an application modernization with target platform agreed, a managed services run with measurable SLAs. We bring the team, the delivery discipline, and the accountability — you get the milestone, the deliverable, and the receipt.

SOW vs ALTERNATIVES

When SOW is the right fit — and when it isn't.

A direct comparison against the two most common alternatives — Time & Materials staff augmentation and Managed Services contracts.

SOW DELIVERY LIFECYCLE

Five phases. One predictable arc, repeated for every engagement.

Every Exolios SOW follows the same five-phase lifecycle — calibrated to the program shape, but always recognizable. Predictability is the feature.

01
2 – 4 weeks

Discovery

Joint scoping with your business and IT stakeholders. Current-state assessment, constraint mapping, dependency surfacing, and acceptance-criteria drafting.

02
2 – 6 weeks

Solution & Estimation

Target architecture, work breakdown, milestone plan, RACI, risk register, and the priced SOW itself — with assumptions explicitly enumerated.

03
8 – 52 weeks

Build & Deliver

Sprint-paced execution with milestone-based billing. Weekly status, monthly steering committee, transparent burn-down against acceptance criteria.

04
4 – 12 weeks

Hypercare

Post-go-live stabilization. Defect triage, performance tuning, knowledge transfer to client run teams, and exit-readiness verification against pre-agreed criteria.

05
Defined per SOW

Transition & Close

Formal handover, documentation lockdown, residual-risk register, post-engagement review, and either close-out or transition into a managed-services SOW.

10

Business-day mobilization

Most pods spin up within 10 business days of signed SOW — talent already pre-vetted, contracts already drafted.

15%

Capped change-order overhead

Contractual cap on cumulative change-order growth before re-baselining is required — protects both sides from drift.

100%

Acceptance-criteria pre-agreement

No SOW signs without exit criteria written in plain language. Milestone billing only releases against acceptance.

SOW PROGRAM TYPES

Six program shapes we run as SOW engagements.

Not every program is a good fit for SOW. These six shapes consistently are — because the scope is bound, the success criteria are measurable, and the vendor can credibly carry the timeline risk.

Cloud Migration

End-to-end migration programs across AWS, Azure, and GCP — including assessment, landing zone, application waves, and decommissioning.

  • Lift-and-shift waves
  • Re-platforming & re-architecting
  • Database modernization
  • Landing zone & CCoE setup

ERP Implementation

SAP S/4HANA, Oracle Fusion, Salesforce, and Microsoft Dynamics implementations — greenfield, brownfield, or selective conversion paths.

  • Functional & technical implementation
  • Data migration & reconciliation
  • Integration & reports build
  • Training, UAT & cutover

Application Modernization

Legacy estate modernization — monolith decomposition, micro-service redesign, container adoption, and event-driven re-architecture.

  • Microservice decomposition
  • Containerization & Kubernetes
  • API-first re-platforming
  • Event-driven architectures

Data Modernization

Data lake, data warehouse, and analytics modernization programs — including governance, lineage, and the AI-readiness layer underneath.

  • Lakehouse & warehouse builds
  • Data governance & lineage
  • Pipeline modernization
  • Self-service analytics rollout

Managed Services

Run-state operations — application support, infrastructure operations, ERP AMS, cloud FinOps, and security operations — under SLA.

  • Application support (L1 / L2 / L3)
  • Cloud & infrastructure ops
  • ERP application maintenance
  • Security & FinOps run

AI / Platform Build-Out

Greenfield AI/ML platform builds, RAG architectures, MLOps environments, and the data-platform groundwork required underneath them.

  • ML platform builds
  • RAG & LLM application development
  • Vector DB & embedding infrastructure
  • MLOps & LLMOps tooling
SOW DNA

What an Exolios SOW actually feels like to live inside.

Six operating commitments that show up in every Exolios SOW — written into the contract, not the marketing slide.

Acceptance-criteria first

No statement of work signs without unambiguous, measurable acceptance criteria for every milestone. We negotiate harder upfront so we negotiate less in delivery.

Milestone-based billing

Invoicing is tied to acceptance, not the calendar. Released milestones release payment. Unreleased milestones don't. The accountability lives in the schedule.

Transparent change orders

Every change order shows the delta against baseline scope, the cumulative drift, and the price impact on a single page. No hidden re-baselining.

Distributed delivery blend

Pods are constructed with clear local-market and India delivery ratios — disclosed in the SOW so you know exactly who sits where.

Knowledge transfer baked in

Every SOW includes a documented KT plan with deliverable artifacts — not "we'll figure it out at the end." Exit-readiness is part of the contract.

Compliance ready, day one

Work authorization reviewed, equal opportunity compliant, FEMA-aligned for cross-border payments. The legal scaffolding is solved before the first invoice is raised.

WHAT YOU GET

A delivery contract, not a staffing invoice.

  • Fixed-price SOW with itemized scope & assumptions
  • Acceptance-criteria-driven milestone schedule
  • Pre-vetted blended pod across local-market and India delivery
  • Dedicated delivery lead and program manager
  • Weekly status reports and monthly steering committee
  • Transparent change-order register
  • Hypercare period built into every engagement
  • Documented knowledge-transfer artifacts at close
  • Risk register reviewed at every milestone
  • Optional transition into managed-services SOW
WHO THIS IS FOR

Built for programs where the destination is clear.

SOW engagements are the right structure when scope can be defined, success can be measured, and the timeline matters. Particularly:

  • Mid-market and enterprise programs with executive-level visibility
  • CIO offices, transformation PMOs, and program directors
  • Customer-side teams running multi-vendor programs who need a delivery anchor
  • Companies who've outgrown T&M staff augmentation but don't want a full Big-4 wrapper
  • Boards or budget owners who need predictable, auditable delivery economics
