Predictika · Window and door system orders

An AI sales agent's window and door order, checked before it goes out

An AI sales agent prepares an order for a window or door system from a public specification guide: the system, the opening size, the sash weight and the glazing. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the guide's published limits and returns a verdict, every reason and the figures it computed.

Scope: REHAU TOTAL70, GENEO and AGILA window and door systems (six systems): maximum size, sash weight, glazing thickness, finish and safety glass. See everything this validator covers

This validator models orders for six systems in the public REHAU Ltd Specification Guide (06.2019), not just the scenarios shown below.

  • Systems — tilt and turn windows (TOTAL70 and GENEO), entrance doors and French doors (TOTAL70), sliding doors and multi-fold doors (AGILA), each with the maximum size, maximum sash or leaf weight and glazing range the guide lists.
  • Size and weight — the opening must not exceed the system's listed maximum size (checked with the sides either way round), and the sash or leaf weight must not exceed its listed maximum; sliding doors allow 75 kg on a three-wheel roller and 110 kg on a five-wheel roller.
  • Glazing and finish — glazing thickness must fall within the range the guide lists (for example 4 to 36 mm on sliding doors, up to 53 mm on GENEO); multi-fold doors have a smaller maximum size in a coloured or foiled finish; French doors must be fitted with safety glass to BS 6262.
  • Stated figure — a maximum sash weight stated on the order is compared with the guide's figure for the chosen system and roller.

Any order for these systems that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the guide lists none, so this validator produces no price build-up or line-item quote), casement and other systems in the guide, colour names, hardware and security ratings, and project-specific engineering.

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 sash heavier than its system allowsOnly with care
Each system has its own weight limit, and sliding doors change it with the roller, so it takes a table of limits plus a rule per system.		The system and roller set the limit, and the weight is compared with it on every call.
Glazing outside the range for the systemOnly with care
A thickness range per system, usually a rule per product that has to be kept in step with the guide.		Each system carries its own range and every thickness is checked against it.
A size limit that changes with the finishOnly with workarounds
Multi-fold doors have a smaller coloured maximum, which means a conditional rule on finish and size together.		Size, system and finish are in one request and compared together on every call.
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.

  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a window or door system from a public specification guide: the system, the opening size, the sash weight and the glazing. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the guide's published limits 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 a pair of French doors (TOTAL70) in a white finish, 2,000 x 2,300 mm, with a 110 kg sash and 48 mm glazing, with standard glazing. It is ready to send.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with four findings, all in one answer. The opening is 2,000 x 2,300 mm; the largest size the guide lists for this system and finish is 2,200 x 1,900 mm (either way round). The sash or leaf weighs 110 kg; the guide lists a maximum of 100 kg for this system. The glazing is 48 mm thick; this system takes up to 44 mm. The other one is on screen.
    6. 
      
  6. The validator returned four 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 sash heavier than its system allows, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the opening to 1,900 x 2,200, the sash or leaf weight to 95 kg, the glazing thickness to 44 mm and the safety glass to BS 6262 to yes. It sets the stated maximum sash weight as to 100 kg.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All four earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Four 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.
