The Story of
Creekside Condominium
At Creekside Condominium in Vancouver,
trees were planted
in the shared courtyard.
However, tall growing trees were planted by
mistake, rather than short trees.
By mistake, tall,
fast-growing trees
were planted rather than short, slow growing trees.
After a few years, the trees grew and covered
the views of a number of apartments.
People were sharply divided over whether to remove the trees or leave them alone.
It became very acrimonious.
The directors were under a lot of pressure from
both sides. They faced a no-win situation.
They heard about Ethelo, and asked if we could help.

A simple breakdown showed 36 possible outcomes
We configured Ethelo and invited
residents to participate.
Each apartment was
given an online
access code.
Owners with 2 units had double influence.
They were able to log into a user-friendly interface
They we able to score each of the 10 options on a scale
They were able to discuss the issues and options with other participants
They were able to weigh the relative importance of the different issues
As they proceeded, they could see their favourite choice emerge, along with the cost implications of that choice.
The Ethelo algorithm used the information provided by the participants to predict the distribution of support for each of the 36 scenarios.
It searched for a “fair” outcome that would leave everyone roughly equally happy.
In the end, the Ethelo result surprised everyone.
Despite a highly polarized debate, it found a solution that almost everyone supported.
Ethelo recommended a compromise that no one had suggested, or even considered:
Just prune the offending trees.
It was no one’s first choice… but no one opposed it.
It was also one of the
cheapest outcomes!
The result: Council voted to simply prune the trees that were blocking the views.
There was no opposition.
“We were delighted with the recent results achieved by Ethelo. We recommend Ethelo as an effective tool in dispute resolution and decision optimization.”
Terry Li, Rancho Management Services
Postscript:
We reconnected with the management company a year later, and asked how it went.
The conversation simply ended, they said.
They were delighted.
