AndEngine Truck Factor #272

Closed gavelino closed 9 years ago

gavelino commented 9 years ago

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 AndEngine and obtained a value of 1.

The developer responsible for this TF is:

Nicolas Gramlich - author of 100% of the files

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

(a) Do you agree that the listed developer is the main developer of AndEngine?

(b) Do you agree that AndEngine will be in trouble if the listed developer leave the project (e.g., if he wins in the lottery, to be less morbid)?

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

Thanks in advance for your collaboration,

(a) @nicolasgramlich is the owner of the repository. (b) AndEngine is in trouble because @nicolasgramlich did not respond to pull request/issues for more than three years now. (c) No, the project is simply missing a maintainer - without maintainer detailed documentation doesn't help.

Hi @winniehell, thank you for your answer.
