Predictika · Steel-enamel shower surface orders

An AI sales agent's shower surface order, checked before it goes out

An AI sales agent prepares an order for KALDEWEI SUPERPLAN steel-enamel shower surfaces from the public brochure: the size, version with or without a tub carrier, drain kit, centre support, colour and finish. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the brochure's published rules and returns a verdict, every reason and the figures it computed.

Scope: KALDEWEI SUPERPLAN shower surfaces: the 41 listed sizes, the three versions, KA 90 drain kits, centre support, colour, finish and installation height. See everything this validator covers

This validator models orders for the KALDEWEI SUPERPLAN floor-level shower surface as described in the public SUPERPLAN brochure (04/2023), not just the scenarios shown below.

  • Sizes and versions — the 41 listed sizes from 700 x 900 mm to 1200 x 1200 mm (each a model number such as 1851), in three versions: the shower surface alone, with a tub carrier, or with an extra-flat tub carrier. The carrier is fitted at the factory and cannot be ordered separately.
  • Drain kit and installation height — the KA 90 drain kits (horizontal, flat or vertical) and the total installation height the brochure gives for each, compared with the height the site allows and with the height the quote states.
  • Centre support — sizes larger than 900 x 900 mm need a centre support; the brochure recommends the KALDEWEI MAS 5305, and any other centre support goes to a person to confirm.
  • Colour and finish — the brochure colours (alpine white, the sanitary colours and the Coordinated Colours Collection) and the standard, PERL-EFFEKT or SECURE PLUS anti-slip finish.

Any SUPERPLAN order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (no public price list was found, so this validator produces no price build-up or line-item quote), other KALDEWEI shower surfaces and bathtubs, mounting systems, seal sets and sound insulation sets (the brochure refers to a price list for these), and delivery. Assumptions: the centre-support rule is read as applying when either side is longer than 900 mm; the brochure gives no total installation height for the version with tub carrier; the installation height available is a figure the quote receives from the site.

The AI sales agentBuilds the shower surface order from the conversation and says it is ready.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A centre support that is needed only above a sizeOnly with care
A rule tied to the size, written for every size that crosses the limit, and kept in step with the brochure.		The size is compared with the limit on every call, together with the other rules.
Sizes that exist only as listed pairs of side lengthsOnly with care
A lookup of 41 listed pairs, with a rule for any pair outside it; a typed size such as 850 x 1000 mm is easy to let through.		The pair of side lengths is looked up and an unlisted size is stopped.
Total installation height that depends on the version and the drain kitOnly with workarounds
The height is a figure computed from two options and then compared with a site measurement, so it needs extra fields and rules.		The height is computed from the version and drain kit and compared with the site height on every call.
A stated installation height that disagrees with the brochureOnly with workarounds
The figure the agent states is free text or a separate field, so it takes an extra rule that compares it with the computed height.		The stated figure is part of the request and is compared with the computed height on every call.
A tub carrier that cannot be ordered separatelyOnly with care
An exclusion between a line item and the surface; it works but has to be written and maintained.		The separate order is stopped and the carrier versions are offered instead.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1A size of L 900 x B 1000 mm is larger than 900 x 900 mm, which needs a centre support (the brochure recommends the MAS 5305); none is quoted.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for KALDEWEI SUPERPLAN steel-enamel shower surfaces from the public brochure: the size, version with or without a tub carrier, drain kit, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the brochure's published rules and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 20 KALDEWEI SUPERPLAN shower surfaces, L 800 x B 1100 mm, as the version with extra-flat tub carrier. The site allows 40 mm of installation height, and the quote states a total installation height of 49 mm. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. No SUPERPLAN size of L 800 x B 1100 mm is listed; the brochure lists 41 sizes from 700 x 900 mm to 1200 x 1200 mm. A size of L 800 x B 1100 mm is larger than 900 x 900 mm, which needs a centre support (the brochure recommends the MAS 5305); none is quoted. The quote states a total installation height of 49 mm; the brochure gives 37 mm for this version and drain kit.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a centre support that is needed only above a size, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the Size, L x B to 800 x 1200, the centre support to MAS 5305 and the stated total installation height to 37 mm.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
