PCNshark
PCN Management for PLM Teams

Turn Supplier PCNs Into PLM-Ready Change Actions

Your PLM system governs product records, BOM revisions, engineering changes, approvals, and controlled release.

PCNshark manages the workflow before formal change control begins: receiving supplier notices, extracting affected parts and deadlines, identifying BOM exposure, assigning initial ownership, and determining whether a controlled product change is required.

Scope

PCNshark complements PLM. It does not replace product-data management, controlled BOM governance, formal engineering change, approvals, effectivity, or release management.

§ The missing step

What happens before formal PLM change control begins?

Before a formal engineering change is created, someone must capture the supplier notice, understand what changed, identify the affected parts, check product exposure, evaluate the deadline, and decide whether controlled change is required.

Typical manual intake
  1. Supplier email or portal
  2. PDF downloaded
  3. MPNs copied manually
  4. BOMs searched
  5. Owners contacted
  6. Impact discussed
  7. Formal change initiated when required
With PCNshark
  1. Supplier notice
  2. PCNshark intake
  3. Extract and verify parts and dates
  4. Identify BOM and product exposure
  5. Assign owner, deadline, and action
  6. Record the disposition
  7. Initiate formal PLM change when required

A PLM change process should not have to begin with an unstructured PDF, a spreadsheet, and an email thread. PCNshark gives the change owner a reviewed notice, identified exposure, deadlines, and an initial response path.

An external supplier notice is not the same as an internal engineering change

The two sound related, but they sit at different stages of the product-change process.

Who creates it
External supplier notice

A component manufacturer or supplier

Internal controlled change

Your company

What it represents
External supplier notice

A part, material, process, site, or lifecycle change

Internal controlled change

How it arrives / is managed

External supplier notice

May require no product change

Internal controlled change

Exists when controlled action is required

PCNshark determines and documents the supplier-notice impact. The PLM system governs formal implementation when necessary.

§ One connected process

From supplier notice to controlled product change

  1. External supplier change: a manufacturer PCN, discontinuation, EOL, or NRND notice arrives.
  2. PCNshark receives, extracts, and verifies the notice, matches it against active BOMs, identifies affected products, and assigns an initial owner.
  3. Decision: Does the supplier notice require controlled product change? If no, record the disposition and close. If yes, prepare the formal controlled change.
  4. The team manually carries the reviewed impact into the platform, which governs the controlled change and release. There is no automatic data sync.

Prepare the formal PLM change process

These PLM concepts are not identical across every platform. PCNshark organizes the supplier-notice triage; your PLM governs the controlled change. The move from PCNshark into the PLM system is a manual step a person takes — there is no automatic data sync.

§ Worked example

Example: one supplier notice triggers controlled product change

An illustrative discontinuation notice, captured and triaged in PCNshark, then handed to the PLM change process. Sample data — not a screenshot of a native integration.

Supplier notice
Notice type
Product discontinuation
Affected MPNs

Last-time-buy date
September 30, 2027
Last-ship date
March 31, 2028
PCNshark impact triage
  1. Affected MPNs extracted and verified
  2. Matched against active BOMs
  3. Affected products surfaced
  4. Owners and required actions assigned
Reviewed impact — ready for controlled change

Yes — substitution + BOM revision

Illustrative example. Customer, supplier, product, and BOM information has been replaced. PCNshark does not create PLM change objects; the change owner opens the change in the PLM system.

PCNshark does not make engineering or quality decisions automatically. It organizes the evidence and workflow required for the responsible team to make and document those decisions.

How PCNshark fits with common product-development systems

PCNshark works alongside your existing PLM, ERP, QMS, or internal change process — not as a replacement.

PTC Windchill

Prepare supplier-notice impact information before formal Windchill change management begins.

Siemens Teamcenter

Turn a supplier PCN into reviewed BOM and product exposure before a Teamcenter change process is initiated.

Arena PLM

Connect document-level PCN intake and disposition with Arena product records and change workflows.

Altium 365

Move from design and BOM risk visibility to an owned response for the actual supplier notice.

Other PLM systems

Use PCNshark alongside an existing PLM, ERP, QMS, or internally developed change process.

PCNshark complements these workflows by organizing the supplier notice and BOM-impact analysis that may trigger them.

§ FAQ

Frequently asked questions

01What is PLM PCN management?＋
It is the operational workflow that handles a supplier product change notice before — and so that it can feed — a formal PLM engineering change: capturing the notice, extracting affected parts and dates, identifying BOM and product exposure, assigning ownership, and deciding whether controlled change is required. PCNshark provides that pre-change-control workflow; your PLM governs the controlled change.
02Should every supplier PCN become an engineering change?＋
No. Many notices require no formal product change. PCNshark helps determine whether an active product is affected and whether the change is acceptable, so a formal PLM change is opened only when it is actually needed.
03Does PCNshark replace a PLM system?＋
No. PCNshark does not replace product-data management, controlled BOM governance, engineering change, approvals, effectivity, or release. Keep your PLM as the system of record; PCNshark handles supplier-notice intake and impact triage.
04Can PCNshark work with BOM exports?＋
Yes. Export your BOM from your PLM or CAD tool and upload the file — PCNshark accepts .csv, .tsv, .txt, .xlsx, .xls, and .xlsm. It does not import a BOM directly from a PLM system.
05Can PCNshark identify affected products?＋
Yes. It matches affected MPNs against the BOMs you upload and surfaces the affected products and assemblies in those BOMs.
06Does PCNshark automatically create change orders?＋
No. PCNshark does not create or modify PLM objects. It produces a reviewed impact record — exportable as a BOM-impact CSV and a PDF impact report — that the change owner references and attaches when opening a change in the PLM system.
07Can PCNshark work with different PLM systems?＋
Yes. PCNshark is PLM-agnostic — it works from the BOM exports and supplier notices your team provides, regardless of which PLM governs your controlled change process. See the Windchill, Teamcenter, Arena, and Altium 365 pages for system-specific framing.
08Who should own supplier-PCN triage?＋
It varies by company, but component engineering, supply chain, and quality typically share the response. PCNshark records an initial owner, action, deadline, and status so the notice does not stall across inboxes.
09Can PCNshark track last-time-buy deadlines?＋
Yes. It captures the effective date and lifecycle status (EOL, NRND, last-time-buy, last-ship) from the notice for review and keeps those deadlines connected to the affected parts and products.
10Does PCNshark make engineering decisions automatically?＋
No. PCNshark organizes the notice, exposure, deadlines, owners, and disposition. Engineering, quality, sourcing, and commercial owners make and document the technical and business decisions.
