Not every approval process needs a workflow engine. If everyone follows the same stable path, a simple hard-coded check is often easier to understand and cheaper to maintain. The mistake is introducing a heavy abstraction before any real variation exists.

The number of approval steps is rarely the deciding factor. The real signal is whether different customers, branches, or record types need to behave differently. If everyone follows the same sequence, hard-coded logic is perfectly reasonable. Once different groups need different routes, approvers, thresholds, or fallback rules, configuration starts to justify its cost.

Teams often overbuild this too early. They design flexible workflow engines for requirements that do not yet exist, then spend years carrying complexity that nobody uses. We have found it is better to ship a clean hard-coded flow first and only introduce an engine once repeated, concrete variation creates genuine maintenance pain.

This transition becomes much easier if the application already talks to a stable interface, such as request approval, instead of embedding approval rules throughout the codebase. If that contract stays the same, the implementation behind it can evolve from a few simple checks into a configurable workflow engine without forcing every feature to be rewritten.

Even simple approval processes should record who approved a request, when they approved it, and under which conditions. Once auditability becomes a requirement, much of the plumbing needed for a workflow engine already exists. In regulated environments, the additional cost of configurable routing is often smaller than teams expect.

A practical rule has worked well for us. If product or operations teams need to change approval behaviour without waiting for an engineering release, build or adopt a workflow engine. If changes are rare and remain tightly controlled by developers, hard-coded logic will usually stay the simpler and better option.
