An AI sales agent's ropeway concept quote, checked before it goes out

An AI sales agent prepares a concept quote for a ropeway: a D-Line chairlift or gondola, a 3S gondola or a TRI-Line, with its speed, departure interval, length, rise, stations, vehicles, options and discount. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product lines and returns a verdict, every reason and the figures it computed.

Scope: Doppelmayr D-Line chairlifts and gondolas, 3S and TRI-Line concept quotes: speed, capacity, line geometry, stations, vehicles, options and discount. See everything this validator covers

This validator models Doppelmayr ropeway concept quotes, not just the scenarios shown below.

  • Product lines — D-Line 4-place and 6-place chairlifts, the D-Line 6-place bubble chairlift, D-Line gondolas with 8 and 10 passenger cabins, the 3S gondola and TRI-Line.
  • Line and capacity — design speed, hourly capacity from cabin size and departure interval, the target passengers per hour, line length, vertical rise, grade and intermediate stations.
  • Vehicles and options — the number of vehicles needed to fill the line, seat heating, loading carpets, bike carriers and sliding doors, each offered only on the models that carry them.
  • Commercial checks — the discount range and the discounts, long lines and heavy loads that go to a person, and the stated seat count and net price against the computed ones.

Any ropeway concept quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: funifor, funitel, monocable people movers, reversible tramways, carpet and platter lifts, tower and foundation design, freight and taxes. The validator shows computed totals but no line-item table.

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
Limits that differ by product lineOnly with care
Speed, hourly capacity, length, rise, grade and stations differ for seven product lines, so each line needs its own limits and the rules must pick the right ones.
The model is a field of the request, and every limit is looked up from it on each call.
Capacity that depends on cabin size and departure intervalOnly with care
The passengers per hour a line can carry comes from the cabin size and the interval between departures, and the target must be checked against it as well as against the model limit.
Cabin size, interval and target are fields of one request and are computed together on every call.
Vehicles needed to fill the lineOnly with workarounds
The number of vehicles depends on speed, interval and line length together, so a separate calculation is needed to compare it with the vehicles quoted.
Speed, interval, length and vehicles are fields of the request and are compared on every call.
Options that exist on some models onlyOnly with care
Heating, carpets, bike carriers and doors each belong to certain models, so each option needs its own compatibility rule.
The option choices and the model are in one request and checked together on every call.
Stated seats and net price that must match the computed onesOnly with workarounds
The seat count and the price are computed from vehicles, line, options and discount, so a separate rule is needed to recompute them and compare them with the stated figures.
The stated figures are fields of the request and are compared with the computed ones on every call.
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

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.

Narration transcript

The text of the narrated walkthrough, step by step.

  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a concept quote for a ropeway: a D-Line chairlift or gondola, a 3S gondola or a TRI-Line. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product lines and returns a verdict, every reason and the figures it computed.
  2. I will start with the first request by the agent.
  3. The agent says. Please quote a D-Line gondola with 10-passenger cabins: 2,400 meters long with a 600 meter rise, 4 intermediate stations, a design speed of 6.5 meters per second. It has 600 passenger places in total and a net price of 18,600,000 dollars. The rest of the request is on screen.
  4. Before it goes out, the agent calls the validator.
  5. Blocked, with six findings, all in one answer. The design speed of 65 decimeters per second is above the 60 this model is quoted for. With this departure interval of 7 seconds the line would carry more than the 4,500 passengers per hour this model is quoted for. 4 intermediate stations are quoted; this model is quoted with up to 3. The other three are on screen.
  6. The validator returned six 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. What this shows: for stated seats and net price that must match the computed ones, a rules-based CPQ can do this only with workarounds.
  8. Now the agent resubmits.
  9. The corrected request. It changes the intermediate stations to 0, the design speed to 6, the departure interval to 8 s, the vehicles to 100, the seat heating to no, the stated passenger places to 1,000 and the stated net price to 13,840,000 dollars.
  10. It calls the validator again.
  11. This time the validator clears it.
  12. All six earlier findings are cleared.
  13. Six 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.
