Roadmap
At this point, we have a complete port of the oref algorithm from Javascript to Swift. At a high level, the three steps we want to go through are:
- Small scale testing
- Beta testing shadow mode
- Beta testing swift algorithm
- Release
Small scale testing
At this stage, the implementation is in the Trio-dev repo and there
are a small number of known testers running the algorithm. The Swift
implementation runs in shadow mode where we execute it, compare the
results against JS, and log any inconsistencies for further analysis.
The exit criteria for this stage is:
Ensure no inconsistencies for the large database (200k+) of inputs we have.
Fix any known bugs in the Swift implementation (all documented via GitHub issues)
Do an analysis on the algorithm bugs we fixed in Swift to confirm that the resulting changes to the algorithm are safe and within our expected bounds.
Add the ability to test fixed JS in the app before logging inconsistencies to reduce the logging volume.
Beta testing shadow mode
At this stage, we move the algorithm to the main Trio repo on the
dev branch. The Swift implementation is still running in shadow mode
while we collect more data.
The exit criteria for this stage is:
- No inconsistencies in the algorithm for one week of operation
Beta testing swift algorithm
At this stage, we move to using the Swift implementation for dosing decisions, but we keep the JS implementation to check for inconsistencies and log inputs for any inconsistent runs.
The exit criteria for this stage is:
- No inconsistencies in the algorithm for one month of operation
Release
At this stage, the port is complete. The swift code is running and we productionize the implementation.
Productionization includes:
Removing the JS implementation from the repo
Refactoring the replay mechanism or removing it depending on if we want to use it for other features in the future
