Predictika · Subway 3.0 bathroom suites

An AI sales agent's bathroom suite order, checked before it goes out

An AI sales agent prepares an order for a Subway 3.0 bathroom: vanity unit and washbasin, wall-hung WC with a ViConnect frame, seat, flush plate and mirror cabinet. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of what fits with what and returns a verdict, every reason and the figures it computed.

Scope: Villeroy & Boch Subway 3.0 bathroom suites: vanity units and washbasins, wall-hung WCs with ViConnect frames, flush plates, seats and mirror cabinets. See everything this validator covers

This validator models orders for the Villeroy & Boch Subway 3.0 collection, not just the scenarios shown below.

  • Vanity units and washbasins — vanity units for 500 (handwashbasin), 600, 800, 1000 and 1300 mm washbasins in Brilliant White, Black Oak or Dark Berry; each vanity unit takes the matching washbasin; washbasin tap-hole options; the wall length the vanity unit needs.
  • WCs and ViConnect — wall-hung WCs, each with its own ViConnect concealed-cistern frame (820, 985 or 1120 mm high), flush plate (Matt Black, White or Chrome), full-flush volume of 3 or 4.5 litres and soft-closing QuickRelease seat.
  • Mirror cabinets and project orders — the mirror cabinet over the vanity unit, the width stated by the agent compared with the width computed, and approval for project orders of 50 suites or more.

Any Subway 3.0 bathroom order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (this validator produces no price build-up or line-item quote), other collections such as Venticello, O.novo or Architectura, ViClean shower toilets, taps and showers, and bathtubs and shower trays. Some rules are modeled from comparable bathroom products rather than taken from Villeroy & Boch documents (see the footnote).

The AI sales agentBuilds the bathroom 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 washbasin that must match its vanity unitOnly with care
A product rule per vanity size can restrict the washbasin choice. It works, but every size and every new washbasin needs its rule kept up to date.		The vanity unit width and washbasin width travel in one request and are checked against each other.
One frame, seat and flush plate for every wall-hung WCOnly with workarounds
The count of frames and seats has to equal the count of WCs. Rules handle quantities poorly, so a rep can add a second WC and forget the frame.		The counts are compared on every call and a missing or extra frame or seat is a finding.
A frame height that must fit the pre-wallOnly with care
The installation height is a free-entry field. A rule can compare it with the frame height, but someone has to write and maintain it.		The pre-wall height and frame height are compared on every call.
Wall length computed from the vanity unitOnly with workarounds
The wall needed is the vanity unit width plus clearance, then compared with the wall available and with the figure the agent stated. That needs calculated fields and a comparison across several selections.		Wall needed is computed from the vanity unit on every call and compared with both the wall available and the stated figure.
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.

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

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 a Subway 3.0 bathroom: vanity unit and washbasin, wall-hung WC with a ViConnect frame, seat, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of what fits with what 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 order a Subway 3.0 bathroom: a 1300 mm vanity unit in Black Oak. The pre-wall is 1,000 mm high and 2,000 mm of wall is available for the vanity unit. The rest of the request is on screen. The order is for 1 suite and states a vanity unit width of 1,273 mm and 1,373 mm of wall needed.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The washbasin of 1,300 mm is not offered with 1 tap hole(s); only the 1,300 mm washbasin has the 2-hole option, and it has no single-hole option. The order has 2 wall-hung WCs but 1 ViConnect frames; every wall-hung WC needs its own concealed-cistern frame with flush plate. The 1,120 mm frame will not fit a pre-wall installation height of 1,000 mm.
    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 order are checked against each other.
    7. 
      
  7. What this shows: for one frame, seat and flush plate for every wall-hung WC, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the tap holes to 0.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with two findings, all in one answer. The order has 2 wall-hung WCs but 1 ViConnect frames; every wall-hung WC needs its own concealed-cistern frame with flush plate. The 1,120 mm frame will not fit a pre-wall installation height of 1,000 mm.
    12. 
      
  12. One finding cleared. Still blocking: each wall-hung WC needs its ViConnect frame and frame taller than the wall.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the ViConnect frames to 2 x 1120 mm and the pre-wall height to 1,250 mm.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. Both earlier findings are cleared, and the validator's figure matches the order.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    19.
