Ionic Truck Factor

[gavelino]

As part of my PhD research on code authorship, we calculated the Truck Factor (TF) of some popular GitHub repositories.

As you probably know, the Truck (or Bus) Factor designates the minimal number of developers that have to be hit by a truck (or quit) before a project is incapacitated. In our work, we consider that a system is in trouble if more than 50% of its files become orphan (i.e., without a main author).

More details on our work in this preprint: https://peerj.com/preprints/1233

We calculated the TF for Ionic and obtained a value of 2.

The developers responsible for this TF are:

Andrew Joslin - author of 47% of the files
Adam Bradley - author of 41% of the files

To validate our results, we would like to ask Ionic developers the following three brief questions:

(a) Do you agree that the listed developers are the main developers of Ionic?

(b) Do you agree that Ionic will be in trouble if the listed developers leave the project (e.g., if they win in the lottery, to be less morbid)?

(c) Does Ionic have some characteristics that would attenuate the loss of the listed developers (e.g., detailed documentation)?

Thanks in advance for your collaboration,
