An AI sales agent's construction hoist quote, checked before it goes out

An AI sales agent prepares a rack and pinion hoist quote for a contractor: a hoist, a drive unit, a mast, a region, a travel height, a load, a speed, a tie spacing and a number of hoists. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the hoist rules and returns a verdict, every reason and the price it computed.

Scope: Rack and pinion construction hoists: three hoists, two drive units and two masts, with region, travel height, load, speed, tie spacing, quantity and discount. See everything this validator covers

This validator models rack and pinion construction hoists in the style of Alimak, not just the scenarios shown below.

  • Load and height — the load and travel height against what each hoist is rated for, with an application engineering review above 90 percent of the load rating and a wind load and tie design review for towers above 250 m.
  • Drive and mast — the speed against the hoist and the drive unit, the travel height against the mast, and the tie spacing against what the mast allows.
  • Regional certification — whether the hoist is certified for the EU, the US or Australia.
  • Quantity, discount and size — one to 8 hoists per quote, a volume discount from 2 hoists, an approval band above 5 percent total discount, a limit at 10 percent, and a deal desk review above USD 1,500,000.
  • Stated net total — the net total the quote states against the net total the validator computes.

Any quote for these hoists, drive units, masts and regions is in scope — not only the scenarios pictured here. Not covered: other Alimak product lines such as industrial elevators, platforms or services, real list prices, lead times, installation and rental terms. Every price and limit is an estimate, not a vendor price list.

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
Height against hoist and mastOnly with workarounds
Two separate limits on the same number, one per product, each held in its own rule.		The travel height is compared with both the hoist and the mast on every call.
Speed against hoist and driveOnly with care
A speed limit on the hoist and another on the drive that must both hold.		Both limits are checked and the one that fails is named.
Certification by regionOnly with care
A matrix of products and regions that has to be kept in rules or option filters.		The region is looked up against the certification data of the chosen hoist.
A stated total that must match the computed totalOnly with workarounds
Comparing a stated total with a computed one needs a separate rule per quote layout, and price rules rarely run on stated figures.		The stated net total is a field of the request and is compared with the computed total on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved, 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.

    
1A load of 2,200 kg is outside the 1 to 2,000 kg of the Twin cage rack and pinion hoist.
2The load is above 90 percent of the hoist rating; application engineering must confirm.
3A travel height of 180 m is outside the 1 to 150 m of the Single cage rack and pinion hoist.
4A travel height of 160 m is above the 150 m the Standard mast section supports.
5A speed of 45 m per minute is above the 38 m per minute of the Single cage rack and pinion hoist.
6A speed of 60 m per minute is above the 54 m per minute of the Standard frequency drive unit.
7A tie spacing of 12 m is above the 9 m the Standard mast section allows.
8The Single cage rack and pinion hoist is not certified for the region chosen.
99 hoists are outside the 1 to 8 hoists of one quote.
10Order value of USD 2,514,240 is above USD 1,500,000 and needs a deal desk review.
11Total discount of 12 percent exceeds the 10 percent limit.
12The quoted net total of USD 261,900 does not match the USD 291,000 the validator computed.
13A travel height above 250 m needs a wind load and tie design review by engineering.
14Order value of USD 1,834,560 is above USD 1,500,000 and needs a deal desk review.
15Total discount of 6 percent is above the 5 percent a rep can give; sales director must approve.

  

  

    
Scenarios and results

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a rack and pinion hoist quote for a contractor: a hoist, a drive unit, a mast, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the hoist rules and returns a verdict, every reason and the price it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote one twin cage rack and pinion hoist with a standard frequency drive unit and standard mast sections, for a tower contractor with a 100 m building in the EU: 2,200 kg load. The net total is USD 291,000. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with one finding and one approval, all in one answer. A load of 2,200 kg is outside the 1 to 2,000 kg of the twin cage rack and pinion hoist.
    6. 
      
  6. The validator returned one blocking finding and one approval 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 height against hoist and mast, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the load to 1,800 kg.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. The validator also returns the line-item quote. It starts with Twin cage rack and pinion hoist and Standard frequency drive unit; the other line is on screen.
    13. 
      
  13. Both earlier findings are cleared, and the validator's total, USD 291,000, matches the quote.
    14. 
      
  14. Two problems caught in one call, fixed in one pass, and a clean $291,000 quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
