Centralized ECN records
Create an ECN with an automatically assigned reference number in the format ECN-YYYY-0001 on first save. Capture title, change type, priority, product, part number, revision from/to, dates, and supporting change details.
Engineering change management
Engineering Change Note (ECN) Software for Manufacturing
Control product, process, material, tooling, and document changes with a structured ECN workflow. SoftDesigners helps manufacturing teams record change details, review impact, manage sequential approvals, track implementation, and retain change history in one centralized platform.
Part of the SoftDesigners Manufacturing Operations Platform. ECN is a separately licensed module.

Why change control matters
Bring structure to manufacturing engineering changes
Manufacturing changes can affect product specifications, part revisions, materials, tooling, work instructions, and production methods. When change requests are scattered across email threads and spreadsheets, teams may struggle to see which changes are awaiting approval, what has been decided, and whether implementation has been completed.
ECN software provides a structured record for the change, its rationale, impact assessment, required actions, approvals, and implementation details. This helps teams coordinate changes and improve visibility without relying on disconnected records.
Common change-control challenges
Issues that can make engineering change management difficult
Unclear ownership
Unclear ownership of engineering change requests.
Incomplete assessments
Incomplete change details or impact assessments.
Approval visibility
Limited visibility into pending approvals and overdue notes.
Decision traceability
Difficulty tracing approval decisions and comments.
Implementation clarity
Unclear implementation responsibility or effective dates.
Disconnected records
Different teams maintaining separate change records.
ECN Module Capabilities
Key features of ECN management software
Manage the lifecycle of an engineering change from the first draft through approval, implementation, and closure—with configurable records and traceable status history.
Sequential approval stages
Route a submitted ECN through configured approval stages in order. The first pending stage's approver acts next. A rejection at any stage rejects the ECN; approval by the last stage moves it to Approved.
Impact assessment and action plan
Document what is changing, why the change is required, the impact assessment, affected documents, and the action plan before submitting the request.
Revision and date tracking
Record the product or part revision being changed and the proposed revision, along with requested, required-by, and effective dates.
Implementation tracking
Record who implemented the change, when it was implemented, the effective date, and implementation notes before closing the ECN after verification.
Approval controls and traceability
Restrict approve/reject decisions to designated approvers or administrators. Rejection requires a comment, and status changes are recorded in the ECN History and Audit Log.
Configurable ECN form
Administrators can rename fields, add help text, hide fields, set required fields, reorder the layout, and edit dropdown choices to fit internal procedures.
Custom fields
Add Text, Multi-line, Number, Date, Dropdown, and Tick box fields. Custom field values are stored on the ECN record.
Search, status counters and CSV export
Search by ECN number, title, product, part number, and requester. Filter by status, view open, awaiting-approval and overdue counters, and export records to CSV including custom columns.
From Draft to Closure
How the ECN approval workflow works
Use a consistent process to raise a change, review it through each approval stage, implement the approved action plan, and close the record after verification.
