How to Run a Scenario-Based PIM Vendor Demo (2026): Scripts, Scoring and Checklist

Last updated: 9 November 2026.

To run a scenario-based PIM vendor demo, give every shortlisted vendor the same five to eight scripted scenarios built from your own data: a real supplier file, a real product with variants and a real channel export. Have each vendor run them live in front of the same scoring panel, in the same order, and score each scenario on a fixed scale straight after it ends, before anyone discusses price.

This guide covers how to write the scenarios, ten examples for B2B and B2C, how to score objectively, when you need a proof of concept or a sandbox instead, and a selection checklist you can copy. It follows the scenario method PIMvendors uses in selection projects, which our sister site documents in its guide to scenario-based demos with a library of demo scenarios. PIM Atlas has a short guide to running PIM vendor demos too.

What is a scenario-based demo, and how is it different from a standard sales demo?

A scenario-based PIM demo is a vendor demonstration of your real use cases on your own sample data, following a script you wrote. A standard sales demo follows the vendor's script on the vendor's data: the record is complete, the category already exists, the mapping was done last week and the exception path never shows up. Nothing in it is false, but it answers a question you never asked.

	Standard sales demo	Scenario-based demo
Who writes the script	The vendor	You, before the first vendor call
Data	Prepared demo catalog	An anonymised sample of your real data, including the messy parts
Order and time	Whatever the presenter chooses	The same scenarios, order and time slot for every vendor
What it shows	The product at its best	How the product handles your work, including exceptions
How it is judged	Overall impression	A score per scenario against criteria written in advance

The difference shows up in the decision. After three standard demos, a buying group usually argues about presentation style, because that is the only thing that differed. After three scripted demos it compares scores on the same tasks. Our post Bring your worst supplier file to the PIM demo makes the case in more detail.

How do you write demo scenarios?

Start from the tasks that decide whether the project works, not from a feature list. Each scenario needs four things: the real input, what the vendor must show live, what you will deliberately break, and what a correct result looks like, written down before any vendor sees it.

Scenario	Your input data	What the vendor must show live	Pass criteria
Onboard a supplier file	Your worst real supplier spreadsheet, anonymised	Import, mapping to your attributes, validation errors and how they are fixed	Every row lands or fails with a readable reason; the mapping is saved for next time
Model a product with variants	One of your products with its real variant axes	The product model, inherited and variant-level values, a change to a shared attribute	The change reaches every variant in one action, and variant-specific values stay intact
Export to a channel	A real channel or marketplace template you send in advance	Mapping, a completeness check and the export file or feed	The output passes the channel's validation without manual edits outside the PIM
Approve a change	Your approval rule for one attribute group	A change, the review task, approval and the audit trail	The change is blocked until approval, and the history shows who did what and when

Use a short script per scenario: context in one sentence, the input file, the steps you expect to see, the deliberate break, and the pass criteria. Keep the script fixed once the first vendor has it.

Ten example scenarios for B2B and B2C

Pick five to eight that matter for your catalog. The codes in brackets refer to the matching scenarios in the PIM Selection demo library.

#	Scenario	Fits	What it tests
1	Onboard your worst supplier file, then rerun it with a changed column	B2B, B2C	Import, mapping reuse, validation and error handling
2	Add a new product family with inherited attributes (SC-05), performed by a business user from your team	B2B, B2C	Whether data model changes need a specialist
3	Model a product with real variant axes and change one shared value	B2C, B2B	Variant model and inheritance
4	Model kits, spare parts and accessories (SC-06)	B2B	Product relations for B2B catalogs
5	Classify a product in ETIM and export the class with its features	B2B wholesale and manufacturing	Classification standards and value lists
6	Link assets to products and variants (SC-09)	B2C, B2B	Asset roles, order and the DAM link
7	Export a retailer or marketplace feed on a template sent one day before (SC-14)	B2C, B2B	Channel mapping effort and completeness per channel
8	Run an approval workflow on a regulated attribute and show its history (SC-24)	B2B, regulated B2C	Workflow, audit trail and history per attribute
9	Generate descriptions with AI, then let a human review, reject one and see the audit entry	B2C, B2B	AI enrichment with governance, review step and rollback
10	Bulk edit one attribute across a category, then undo part of it	B2C, B2B	Mass editing, validation and reversibility

Each scenario connects to deeper guides on this site: ETIM and supplier data in wholesale, the product data model, PIM and marketplaces and PIM features and capabilities. For a manufacturer selling through distributors, the B2B PIM requirements checklist helps you choose which scenarios carry the most weight.

How do you score a demo objectively?

Score each scenario, not the session. Use one scale for every scenario and write the anchors down before the first demo.

Score	Meaning
5	Done live in the product on your data, in standard configuration, within the time slot
4	Done live on your data, with configuration the vendor prepared and explained
3	Done, but with a workaround, a script or a step outside the PIM
2	Partly shown, or shown on the vendor's own data
1	Not shown, shown on slides, or promised for a future release

Four rules keep the scores honest:

1. The same panel scores every vendor. Swapping people between demos changes the scale.
2. Score alone first, then agree. Each panel member writes a score and one line of evidence before the discussion.
3. Separate core from extras. Record per scenario whether what you saw is in the quoted product, needs another module or a partner, needs custom work, or sits on a roadmap without a date.
4. No price before the scores. Open the commercial offers once the demo scores are final.

Weight the scenarios by the requirements they test and combine them with the rest of your evaluation. The scoring matrix in how to select the right PIM and the scoring approach in the PIM RFP guide show how the demo scores feed the final decision.

Demo, proof of concept or sandbox: which do you need?

	Scripted demo	Proof of concept	Sandbox or trial
What it is	The vendor runs your scenarios live on your sample data	One or two high-risk requirements tested in depth on your data	Your own team uses the product
Who	Two or three shortlisted vendors	Usually the top two	One or two finalists
Effort	Preparation of the script and data; one session per vendor	About a week per vendor, against pass criteria written in advance	Your team's time to learn and test
Answers	Which vendor handles your work best	Whether a specific risk can be solved	Whether your users can work with it
Use when	Always, as the core of the evaluation	A requirement the demo could not settle, such as performance at your volume or a complex integration	Usability is a deciding factor, or the vendor offers a trial by default

A proof of concept is not a longer demo. Keep it narrow: one or two requirements, your data, written pass criteria and a fixed end date. If a vendor offers a trial or sandbox, check on its own website what the trial includes and for how long before you plan around it.

Selection checklist

Use this checklist to run the evaluation around the demo. It covers the full selection, so you can copy it into your own plan.

#	Step	Done when
1	Business goals and the problem the PIM must solve are written down	Each goal has an owner
2	Current catalog is profiled	You know product counts, attributes, sources, channels and languages
3	Data model for two or three representative families is drafted	The most complex family is included
4	Data owners and stewards are named	One owner per attribute group
5	Requirements are prioritised	Must-haves are testable and fit on one page
6	Integration landscape is mapped	ERP, commerce, DAM and channel connections are listed with direction
7	Budget range and total cost model are agreed	Licence, implementation and internal effort over several years
8	Longlist is narrowed to a shortlist of two or three	Each vendor kept or dropped with a written reason
9	Five to eight demo scenarios are written	Each has input data and pass criteria
10	Sample data is anonymised and ready	Includes your worst supplier file and a real channel template
11	Scoring panel and scale are fixed	Same people for every vendor; anchors written down
12	Script and data are sent to every vendor	Same version, same date, one input held back
13	Scripted demos are run and scored	A score and evidence per scenario per vendor
14	Open risks are tested in a proof of concept, if needed	One or two requirements, top two vendors, fixed end date
15	References are checked	Customers of similar size and industry, not only the ones the vendor chose
16	Offers are compared on the same basis	Core PIM, modules, partner work and roadmap items split out
17	Implementation partner is assessed	Named team, design workshop, partner scorecard
18	Contract terms are checked	Notice periods, data export rights, price increases, support levels
19	Decision is documented	Scores, risks and the reason for the choice, signed by the sponsor

How we evaluated

This guide follows the scenario method PIMvendors uses in selection projects and the scenario library published on our sister site pimselection.com, whose codes we reference. We aligned it with the demo guidance on PIM Atlas and pimsysteem.nl. We do not name vendor trial or sandbox offers, because their terms change often; check them on each vendor's own site. We give no durations or success rates beyond the method itself, because no source we could check states them in a way that transfers to your selection.

PIMvendors is an independent PIM selection platform. Our scenario-based selection service runs this process for buyers who want an independent lead.

Next step in your selection

With the demo scores in hand, two steps follow. Turn the winning scenarios and requirements into your tender in the PIM RFP guide, and once the platform is chosen, use the same scripted approach for the build team in how to choose a PIM implementation partner. The PIM ROI business case helps you take the decision to your board.
