ISO-certified manufacturers usually manage non-conformances and CAPAs in spreadsheets, email threads, or a disconnected QMS point tool — while the actual defect, batch, supplier, and work order data all live in ERPNext. The result is a broken audit trail: an NCR raised in one system, a corrective action tracked in another, and no reliable link back to the Item, Batch, Work Order, or Purchase Receipt that triggered it. ERPNext core has a Quality Inspection DocType and a lightweight Non Conformance in the Quality Management module, but neither gives you a structured CAPA lifecycle: root-cause analysis, assigned actions with due dates, effectiveness verification, and gated closure approvals that would satisfy an ISO 9001 clause 10.2 audit. That is where native ERPNext runs out of road.

ECOSIRE builds a proper Frappe app (for example ecosire_capa) with its own module, so it upgrades cleanly and never patches ERPNext core. At its heart are purpose-built DocTypes: a Non Conformance Report for intake and triage, a CAPA document for the corrective/preventive lifecycle, and supporting child tables for root-cause entries, action items, and verification records. The NCR links directly to the originating ERPNext document — Quality Inspection, Item, Supplier, Batch, Work Order, or Stock Entry — via Dynamic Link and Link fields, so every non-conformance stays traceable to source. A configurable Frappe Workflow moves records through states (Open, Triage, Investigation, Action In Progress, Verification, Closed) with role-scoped transitions, and hooks.py document events (validate, on_submit, on_update_after_submit) enforce the rules — you cannot close a CAPA until every action is complete and an effectiveness check has passed.

The root-cause toolkit is embedded, not bolted on: a 5-Why child table that captures each successive "why" as a row, and an Ishikawa (fishbone) structure that categorizes causes across the standard 6M dimensions (Man, Machine, Method, Material, Measurement, Environment). Actions are individual records with an owner, a due date, and priority — assigned through Frappe's native ToDo/assignment system so they appear in the owner's workspace and notifications. A scheduler event (scheduler_events in hooks.py) runs daily to flag overdue actions, escalate to the QA lead, and email reminders. Whitelisted server methods (@frappe.whitelist()) expose actions such as "generate CAPA from NCR", "record verification result", and "request closure" to client scripts and the Frappe REST API, so the workflow can be driven from custom dashboards, mobile, or an external MES. Permissions are enforced with role profiles (QA Inspector, CAPA Owner, QA Manager/Approver) and User Permissions so reviewers only see records in their scope, and every state change is captured in the built-in version/audit trail for auditor review.

Because this is build-to-order, nothing ships until we agree on your scope. A short scoping call maps your NCR categories, severity classification, CAPA states, approval roles, and which ERPNext transactions must link back to a non-conformance. We build against Frappe/ERPNext v15 or v16 to match your environment, validate on a staging copy of your instance with your real QA team (UAT), then install to production with a rollback plan. Typical delivery is one working week from confirmed scope, and you receive the full installable source, git repository handover, and a post-go-live support window — you own the app, not a locked black box.
