Sky(scraper) is the limit

The challenge

You and your team are invited to CGI & KONE sky(scraper)-is-the-limit challenge, where you will build unimaginable creative solution to make maintenance services even smarter. This challenge is from serious elevator maintenance service business. Keep reading if you are interested to learn more about a global real-life challenge.Our goal is that a technician is never sent to the field without an actual upcoming maintenance need. Your task is to recognize which service action recommendations are relevant. You are allowed to use any programming language or tool and get creative. In the end only the result matters.

This challenge can be approached in two ways:

1. Treat this as a pure machine learning challenge and build a Best Performing and/or Most Explainable model. This is for you and for your team if:

  • you have solved machine learning issues in your sleep
  • you float in the data lake
  • you speak Python, R or any other programming language
  • you enjoy to get your hands dirty

2. Or get creative with Out of the Box Thinking. Impress us with a solution we have not even imagined before.


Elevators, escalators, and automatic building doors with KONE 24/7 Connected Services are constantly sending data to the cloud where it is analyzed and potential issues are identified. Appropriate action recommendations are then automatically sent to maintenance technicians who will resolve the issues before they happen. The action recommendations are created by a host of algorithms from heuristics to machine learning models. Technician feedback is used to constantly improve these algorithms.Your challenge is to create a solution that evaluates the action recommendations and makes the final decision which ones to send to technicians and which ones to discard based on the technician feedback.

What We'll Bring

During the event, we will provide you a dataset of sent service action recommendations and their outcomes. Our subject matter experts and machine learning gurus will also be there to support and mentor you.

As the provided dataset is real production data, the participating teams will need to sign non-disclosure agreements (NDA) before hacking.

The Prizes

Winners in both categories will get 1000 € and a visit in KONE R&D site People Flow Center in Hyvinkää. Visit can be virtual as well if you are not located in Finland.

Judging criteria

Impress us and do your best together with your team to win one of the recognition categories:

  • Best Performing Model and Most Explainable Model
  • Out of the Box Thinking
