Product-rule examples across industries

Core types of product rule

A choice may change the availability, dimension, quantity, appearance or price of other choices. Without explicit relationships, a combination may look possible while being impossible to manufacture.

Move rules from scattered documents into one inventory

Product rules may be scattered across catalogue footnotes, price sheets, CAD drawings and the knowledge of experienced sales staff. Discovery should combine these sources into a shared rule inventory.

Each record should contain the condition, outcome, affected products, explanation, source document and owner. Visual behaviour, price and product code can then be traced to the same decision.

Furniture and storage

Modular seating may combine connection direction, corner modules, fabric coverage and leg choice. Cabinets connect overall width, carcass modules, door count, internal fittings and room height.

• Corner and end-module direction
• Fabric quantity by module
• Door width and track limits
• Internal fitting compatibility
• Wall and ceiling clearances

Yachts, pergolas and facade systems

A boat model and engine version can define the initial option set. In pergola and facade systems, opening dimensions, supports, roof type, panel count and opening direction interact.

The visual model does not replace engineering calculations. Structural capacity, regulations and manufacturing suitability remain with the verified technical system.

• Equipment list by model
• Panels or supports by length
• Corner joins and opening direction
• Technical limits by environment
• Separation of visual choice and engineering approval

Industrial products and equipment

Industrial configuration gives technical capacity and part codes as much importance as appearance. Motor, controls, conveyors and safety equipment can depend on power, size and use case.

• Components by capacity
• Electrical and connection compatibility
• Mandatory parent parts
• Part-code and revision mapping
• Choices that require technical approval

Present each rule as an understandable user behaviour

Silently removing an option can make customers think the catalogue is incomplete. Explain why a choice is unavailable, what can resolve it and what the system changed automatically.

Do not expose raw engineering language directly to customers. Translate the product rule into a short, actionable interface message, with more detail available to sales when needed.

• A short reason for a disabled option
• Notice when a mandatory part is added
• Allowed range at a dimension limit
• A corrective suggestion for conflicting choices
• A clear next step when technical approval is required

Validate rules through scenarios

Turn a rule table into scenarios the product team can review. Test minimum and maximum dimensions, mutually exclusive choices, defaults and stale data.

Assign an owner and update source to each rule. A product change may affect the visual part, code, price and integration mapping as well as interface text.

1. List valid reference configurations
2. Define invalid combinations and reasons
3. Test boundary values
4. Compare price and code effects
5. Obtain product-team approval
