Case Studies

Cohesive in Complex, High-Scale Systems

Cohesive was not designed in abstraction.

It was shaped by building and scaling systems across industries where correctness, workflow complexity, search, and distributed execution are non-negotiable.

These domains look different on the surface. Underneath, they share the same structural failures:

State scattered across services
Search models drifting from source truth
Workflow logic fragmented across layers
Indexes and ledgers maintained separately
Invariants enforced inconsistently

Cohesive addresses these problems at the semantic level.

Below are representative industries where these challenges emerge in full force.

Mapping Industry Challenges to Cohesive Building Blocks

Structural Challenge	Entities	Transitions	Processes	Relations	Host
State fragmentation across services	Canonical state model centralizes fields and invariants	Legal state evolution defined explicitly	Coordinates multi-entity changes coherently	Derived views generated from source state	Configures storage & execution boundaries without redefining semantics
Workflow complexity (multi-step lifecycles)	Defines lifecycle-relevant state	Encodes valid step transitions	Orchestrates multi-step, multi-entity flows (lightweight or durable)	Produces operational queues & dashboards	Executes atop ASP.NET, Durable Task, Orleans, or RDBMS transactions
Search / index drift from domain model	Single source of truth for domain state	Ensures index-triggering mutations are explicit	Manages async projection flows if needed	Declares search/index views as derived relations	Binds to Elastic, OpenSearch, SQL, or in-memory backends
Integration & mapping explosion (EDI, APIs, feeds)	Canonical entity shapes stabilize mapping targets	Integration events become formal transition inputs	Coordinates retries, compensations, and external calls	Integration-facing views derived from entities	Configures adapters for storage and execution without leaking semantics
Transactional correctness under concurrency	Encodes invariants at field level	Restricts illegal state changes	Supports transactional or durable execution strategies	Ledger and audit views derived from transitions	Selects appropriate execution runtime (DB transaction vs distributed workflow)
Identity resolution & deduplication drift	Canonical identity representation	Merge/split operations defined as auditable transitions	Identity resolution pipelines modeled explicitly	Search index derived from reconciled entity	Controls multi-region or batch execution models
Ledger / reporting divergence	Operational state defined once	Financial-impacting events explicit	Billing / settlement workflows coordinated	Ledger declared as relation over transitions	Supports event-driven or transactional persistence models
External system unreliability	Internal state remains authoritative	External inputs normalized as transitions	Retry logic, compensations, sagas modeled as processes	Monitoring views derived from workflow state	Durable execution model selectable without rewriting semantics
Human-in-the-loop overrides	Explicit representation of overrideable fields	Override operations encoded as legal transitions	Processes pause, resume, or branch safely	UI views reflect canonical state	Host integrates with web APIs and messaging layers cleanly
Semantic entropy over time	Stable domain schema	Controlled evolution of state	Versioned workflow definitions	Deterministic derived models	Execution infrastructure replaceable without altering model

Why This Matters

Across industries:

Entities eliminate duplicated state definitions.
Transitions eliminate hidden business logic.
Processes eliminate ad hoc workflow orchestration.
Relations eliminate drift between operational truth and search/reporting.
Host eliminates infrastructure lock-in while preserving semantics.

This table makes the argument concrete: Cohesive is not an abstraction layer. It is a structural correction to recurring failure modes in complex systems.

Executive Summary — How Cohesive Addresses Systemic Risk

Across productivity, e-commerce, logistics, payments, and healthcare platforms, the underlying risks are consistent:

Scattered system state
Fragile workflows
Search and reporting drift
Financial reconciliation gaps
Integration complexity
Infrastructure lock-in

Cohesive addresses these structurally.

Business Risk	Operational Impact	Cohesive Building Block	Executive Outcome
Fragmented system state	Inconsistent behavior, hard-to-debug defects	Entities	Single source of truth for core business objects
Hidden workflow logic	Costly production incidents, brittle scaling	Transitions + Processes	Explicit, verifiable lifecycle control
Search & reporting drift	Conflicting dashboards, unreliable analytics	Relations	Consistent operational and analytical views
Financial reconciliation gaps	Revenue leakage, audit exposure	Transitions + Relations	Ledger derived directly from system events
Integration sprawl	Slow partner onboarding, custom glue code	Entities + Processes	Standardized, reusable integration patterns
Infrastructure coupling	Expensive rewrites during scaling or migration	Host	Portable execution across runtimes and storage engines

Executive-Level Impact

When applied systematically, Cohesive produces:

Fewer production incidents caused by workflow ambiguity
Reduced reconciliation and reporting overhead
Faster onboarding of new integrations and partners
Lower long-term maintenance burden
Greater adaptability to new infrastructure and AI-driven capabilities

In short: Cohesive reduces operational entropy while preserving architectural flexibility.
