An AI sales agent's Arjo Maxi Sky 2 ceiling lift order, checked before it goes out

An AI sales agent prepares an order for a hospital: Arjo Maxi Sky 2 or Maxi Sky 2 Plus ceiling lifts, a safe working load, a hand control, powered traverse, a spreader bar, charging, a rail layout, a ceiling survey, a sling and the battery transfers per charge it states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public Arjo specifications plus ordering rules modeled from comparable ceiling-lift programs, and returns a verdict, every reason and the figures it computed.

Scope: Arjo Maxi Sky 2 and Maxi Sky 2 Plus ceiling lifts only: safe working load, control, traverse, spreader bar, charging, rail, ceiling survey, sling and battery figures. See everything this validator covers

This validator models orders for the Arjo Maxi Sky 2 and Maxi Sky 2 Plus ceiling lifts, not just the scenarios shown below.

  • Model and capacity — Maxi Sky 2 is set to 120, 200 or 272 kg; Maxi Sky 2 Plus runs at 272 kg (single) or 454 kg (dual mode, two linked lifts with the linked spreader bar). The heaviest patient must not exceed the capacity.
  • Control and traverse — two- or four-function hand control; Maxi Sky 2 Plus has no horizontal motor and its trolley moves by hand, so powered traverse is not offered with it.
  • Charging and battery — Enhanced Charging (ECS) or charging stations on the track, and the transfers per battery charge at the patient weight (for example 70 at 200 kg on Maxi Sky 2), which the order's stated figure may not exceed.
  • Ordering rules (modeled) — rail layout and curves, minimum rail run, charging-station counts, a ceiling survey before ordering, sling rating against patient weight, and reviews by a person for large orders (10 lifts or more) and for daily transfers above one charge.

Any Maxi Sky 2 or Maxi Sky 2 Plus order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Arjo does not publish list prices, so this page shows no price build-up), other Arjo lifts and beds, slings and spreader-bar catalogues, and installation or service terms. The rail, charging-station, ceiling-survey, sling and review rules are modeled from comparable ceiling-lift programs; they are not Arjo-published rules.

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
Capacity settings that differ by modelOnly with workarounds
Maxi Sky 2 and Maxi Sky 2 Plus offer different capacities, and the 454 kg setting also needs the linked spreader bar. A rules-based CPQ needs a compatibility table per model.		The model and capacity arrive in the request and are checked together on every call.
Control, traverse and model togetherOnly with care
Powered traverse depends on the hand control and on the model. It can be built, but each new pairing is another rule to maintain.		Control, traverse and model are checked together, in any order the choices arrive.
Battery transfers per chargeOnly with care
The stated figure depends on the patient weight band, so a rule has to look it up and compare.		The stated transfers are a field in the request, compared with the computed figure 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 person 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 order; approval findings need a person to sign off; everything else is computed.

    
1A safe working load of 300 kg is not offered for this lift model; Maxi Sky 2 is set to 120, 200 or 272 kg and Maxi Sky 2 Plus runs at 272 kg (single) or 454 kg (dual).
2A safe working load of 454 kg is not offered for this lift model; Maxi Sky 2 is set to 120, 200 or 272 kg and Maxi Sky 2 Plus runs at 272 kg (single) or 454 kg (dual).
3The 454 kg dual mode lifts with two linked lifts and needs the linked spreader bar; the order has the Quick Connect bar.
4A safe working load of 120 kg is not offered for this lift model; Maxi Sky 2 is set to 120, 200 or 272 kg and Maxi Sky 2 Plus runs at 272 kg (single) or 454 kg (dual).
5The heaviest patient is 150 kg; the selected safe working load is 120 kg.
6The linked spreader bar is used by Maxi Sky 2 Plus in dual mode (454 kg); it cannot be ordered with this model or capacity.
7The heaviest patient is 230 kg; the selected safe working load is 200 kg.
8Powered traverse (left/right movement on the rail) needs the four-function hand control; the two-function control does not have it.
9Maxi Sky 2 Plus has no horizontal motor and its trolley is moved by hand, so powered traverse cannot be ordered with it.
10Charging by station on the track needs at least one charging station; the order has 0.
11With Enhanced Charging (ECS) the lift charges anywhere on the track, so the 1 charging station(s) on the order are not needed.
1290 transfers a day per lift is more than one charge (70), and station charging means returning the lift to the track station; a person should confirm the charging plan.
13A straight rail has no curves; the order has 2 curve(s).
14A curved rail layout needs at least one curve; the order has 0.
15A traverse (XY) rail system is straight rails only; the order has 1 curve(s).
16The rail run is 1 m; at least 2 m is needed.
17The ceiling structure has not been surveyed for the lift load; a survey is needed before the rail is ordered.
18The sling is rated for 120 kg; the heaviest patient is 150 kg.
19The order states 100 transfers per battery charge; at this patient weight the battery supports about 70.
20The order has 0 lifts; at least 1 is needed.

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 hospital: Arjo Maxi Sky 2 or Maxi Sky 2 Plus ceiling lifts, a safe working load, a hand control, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public Arjo specifications plus ordering rules modeled from comparable ceiling-lift programs, 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 3 Arjo Maxi Sky 2 Plus ceiling lifts set to 454 kg, with the four-function hand control and powered traverse. The heaviest patient is 420 kg. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. Maxi Sky 2 Plus has no horizontal motor and its trolley is moved by hand, so powered traverse cannot be ordered with it. The 454 kg dual mode lifts with two linked lifts and needs the linked spreader bar; the order has the Quick Connect bar. The order states 70 transfers per battery charge; at this patient weight the battery supports about 40.
    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 battery transfers per charge, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the powered traverse to no and the spreader bar to linked.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The order states 70 transfers per battery charge; at this patient weight the battery supports about 40.
    12. 
      
  12. Two findings cleared. Still blocking: stated transfers per charge too high.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the stated transfers per charge as to 40.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is 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.
