An AI sales agent's cooling tower order, checked before it goes out

An AI sales agent prepares an order for an Advanced Technology (AT, UT or USS) induced draft cooling tower: a series, a model range, sound options, access options, a basin heater and the entering water temperature. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product catalog's notes and tables and returns a verdict, every reason and the figures it computed.

Scope: Orders for the AT, UT and USS induced draft counterflow cooling towers: series and model range, sound options, platform and ladder, basin heater sizing, entering water temperature and stated figures. See everything this validator covers

This validator models orders for these cooling towers, not just the scenarios shown below.

  • Series and sound options — UT only on units wider than 4 feet; the super low sound fan and the water silencer not on 4-foot-wide units; the low sound fan on AT and USS only; offset sound walls only together with the super low sound fan and the water silencer.
  • Access options — the working platform and the sloped ladder not on 4-foot-wide units.
  • Basin heater — the catalog heater table across 61 model ranges and three design low temperatures (0, -20 and -40 degrees F): heater count and size, the total in kW, and a factory-consult flag where the catalog gives none.
  • Low sound fan additions — the height and operating weight the low sound fan adds, by model range.
  • Entering water temperature — the standard fill is rated to 130 degrees F; above that the order needs higher-temperature materials, which the catalog says to confirm with an EVAPCO representative.

Any AT, UT or USS order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the catalog lists none, so this validator produces no price build-up or line-item quote), thermal capacity and selection (the catalog sends those to the selection software), the model-by-model dimension drawings, other EVAPCO product lines, and options the catalog only names.

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
Sound options that depend on series and unit widthOnly with workarounds
The super low sound fan, low sound fan, water silencer and sound walls each have their own series and width conditions; they end up as a web of dependent rules.		The series, the model range and every option are checked together and each conflict is reported.
A heater size that depends on model range and design temperatureOnly with workarounds
61 model ranges times three temperatures, some with no listed size; a lookup table the quote has to be compared with by hand.		The heater count, size and total are computed from the catalog table and compared with the figure the quote states.
A low sound fan weight and height that depend on the model rangeOnly with care
Another per-model lookup that has to stay in step with the catalog.		The additions are looked up for the model range and compared with the weight the quote states.
A water temperature limit that moves the order to a different optionOnly with care
A threshold on a process condition decides whether an option is required; a validation rule can express it but only if someone writes it.		The entering water temperature is checked in the same call as the options.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote 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
Click to expand
    
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.

    
1UT towers are available only in sizes over 4 feet wide; this model range is a 4-foot-wide unit.
2The super low sound fan is not available on 4-foot-wide models.
3The low sound fan is available on AT and USS models only; a UT model already has the super low sound fan as standard.
4The quote states 225 lb of added operating weight for the low sound fan, but the catalog gives 450 lb for this model range.
5The water silencer is not available on 4-foot-wide models.
6Offset sound attenuation walls are available only in combination with the super low sound fan and the water silencer.
7The working platform is not available on 4-foot-wide models.
8The sloped maintenance ladder is available on models wider than 4 feet; a vertical ladder is the option for smaller models.
9The standard EVAPAK fill withstands water up to 130 degrees F (55 C); the quote has 131 degrees F and no higher-temperature materials.
10The entering water is above 130 degrees F with higher-temperature materials requested; the catalog says to consult an EVAPCO representative for that option.
11The quote states 48 kW of basin heater in total, but the catalog sizing for this model range and design temperature gives 60 kW.
12The catalog says to consult the factory for the basin heater at this model range and design temperature; a person should confirm the size.
13The standard EVAPAK fill withstands water up to 130 degrees F (55 C); the quote has 135 degrees F and no higher-temperature materials.

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 an Advanced Technology (AT, UT or USS) induced draft cooling tower: a series, a model range, sound options, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product catalog's notes and tables 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 an EVAPCO UT cooling tower, model range 14-2F6 to 14-3G6. The design low ambient temperature is 30 degrees F and the entering water is 95 degrees F. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. UT towers are available only in sizes over 4 feet wide; this model range is a 4-foot-wide unit. The water silencer is not available on 4-foot-wide models.
    6. 
      
  6. The validator returned two 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 heater size that depends on model range and design temperature, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model range to 19-2G6 to 19-4J6.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. Both earlier findings are cleared.
    13. 
      
  13. Two 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.
    14.
