Workflow Engine Laravel Package

Product Decisions This Supports

• Build vs. buy for stateful domain logic. Teams constantly re-implement "status" columns, enum casts, and if ($order->status === ...) guards by hand. This package lets you decide once whether workflow/state-transition logic is infrastructure you buy (adopt) or bespoke code you own and maintain. Adopting shifts effort from plumbing to product rules.
• Feature decisions around approval and lifecycle flows. Any roadmap item shaped like draft → review → approved → published, cart → paid → fulfilled → refunded, trial → active → churn, or onboarding/verification funnels is a candidate. Framing these as declarative workflows (states + allowed transitions + guard conditions) makes scope and edge cases visible in grooming instead of buried in controllers.
• Roadmap sequencing for auditability and compliance. Transition history/auditing is a recurring requirement for finance, healthcare, and marketplace products. Deciding to model lifecycles as explicit transitions early avoids a costly retrofit when audit or "who changed this and when" becomes a requirement.
• Architecture decision: subclassed vs. separate workflow models (directly affected by v1.1.2). The new release lets a subclassed model declare its own factory. PM-relevant consequence: teams can model several workflow-bearing entities as subclasses of a base model (shared behavior, per-class factories) instead of duplicating model classes. If your design discussion is "one base workflow model with N subclasses" vs. "N independent models," v1.1.2 removes friction from the first option — fewer custom factory/bootstrapping workarounds, less glue code to maintain.
• Risk decision: lock-in and maintenance exposure. The package is single-maintainer, pre-2.0 OSS. That is a product-level risk decision (bus factor, upgrade cadence), not just a technical one — it should be weighed against the delivery speed gained.
• Process signal for engineering: a new feature shipped in a patch version (v1.1.1 → v1.1.2). For planning, treat this as a prompt to pin exact versions and require a contract test suite around workflow behavior, so upgrades stay low-drama.

When to Consider This Package

Consider it when:

• You are on Laravel and your domain has explicit lifecycles (orders, invoices, subscriptions, content, applications) that need guarded transitions rather than free-form status writes.
• You want workflow definitions to be declarative and colocated with Eloquent models, so product and engineering share one vocabulary of states and transitions.
• You need per-model workflow configuration, transition guards, and a record of state changes — without standing up a separate orchestration service.
• You are early enough that adopting a package is cheaper than designing an internal state-machine abstraction and its tests.
• Your modeling approach uses subclassed models (shared base workflow model, per-entity subclasses). v1.1.2 specifically improves this by letting each subclass supply its own factory.
• Team size and traffic are modest: a single Laravel app, one database, no cross-service coordination.

Look elsewhere when:

• You need real orchestration: parallel branches, compensation/rollback, long-running human tasks, timers, retries with backoff, or sagas spanning multiple services. That is durable-execution territory (Temporal, Camunda/Zeebe), not a model-lifecycle package.
• You need a visual workflow designer for non-engineers, or runtime-editable definitions by business users.
• You have strict vendor support, SLA, or security-review requirements that a single-maintainer package cannot satisfy.
• You are not on Laravel, or you need workflow logic outside Eloquent models (queues, events, external systems).
• Your transitions must be strongly consistent under high concurrency across services — evaluate locking/idempotency guarantees before committing; do not assume them.
• The lifecycle is trivial (two or three states, no guards, no audit). Enums plus a few explicit methods are cheaper than a dependency.

Adoption hygiene: pin the exact version (given the patch-level feature bump), wrap usage behind a thin internal interface so definitions can migrate, and require tests that assert allowed and rejected transitions for every model. Treat the package as a maintained dependency with an exit plan, not a permanent platform decision.

How to Pitch It (Stakeholders)

For executives (30 seconds): We have repeated lifecycle logic scattered across features — statuses, approval steps, order states — written by hand each time, which is slow to build, easy to get wrong, and hard to audit. This is a free, Laravel-native package that lets us declare those lifecycles once, with explicit rules about which transitions are allowed and a record of what changed. It reduces custom code and shortens delivery on stateful features, with no new infrastructure or licensing cost. The trade-off is that it is a small open-source project maintained by one person, so we mitigate by pinning versions, testing our workflows thoroughly, and keeping our usage behind a thin internal layer. Recommendation: pilot on one workflow (e.g., order or approval lifecycle) for a sprint, measure the code we avoid writing, then decide on broader adoption.

For engineering: Idiomatic Laravel/Eloquent integration — workflow behavior lives with the models, not in a parallel service. Definitions are declarative (states plus allowed transitions with guards) and testable as data. The v1.1.2 change is small but useful: a subclassed model can now declare its own factory, so an inheritance-based model hierarchy (shared base workflow model with per-entity subclasses) works with standard Laravel factory resolution instead of hand-rolled wiring. It is additive and non-breaking — no migration work expected for current v1.1.1 users. Two asks before we adopt: pin the exact version (a feature landed in a patch release), and write transition tests for every workflow we model — including the transitions that must be rejected — so that upstream changes surface as test failures rather than production surprises. Keep call sites behind a thin adapter so we can swap implementations if maintenance stalls.
