Who drives open software development A community Persons (and organizations) with common goals different interests Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 12 / 54
Self-awareness Open development communities need to be self-aware data is the source for awareness... when it can be used for “sensing” The same applies to any open organization Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 14 / 54
Governance “Establishment of policies, and continuous monitoring of their proper implementation, by the members of the governing body of an organization. It includes the mechanisms required to balance the powers of the members (with the associated accountability), and their primary duty of enhancing the prosperity and viability of the organization.” http://businessdictionary.com Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 15 / 54

Transparency It comes in two flavors Transparency to the community (fairness) Transparency to third parties (trust) Which for open organizations are kind of the same Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 17 / 54
Transparency Example of rationale (OpenStack): “OpenStack favors disclosure and transparency to promote sharing and collaboration within the OpenStack community” https://www.openstack.org/legal/transparency-policy/ Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 18 / 54
A new dimension of openness When we develop in the open we produce a great deal of data about how we develop “Show me the development data” as a step beyond “show me the code” Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 21 / 54
From open development to open development analytics Information about code, community, development for open development projects can be retrieved, organized, analyzed Let’s publish analytics results & data Open Development Analytics: A new standard for transparency Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 22 / 54
Open development analytics Who may benefit? Developers Project managers Community managers Evaluators ... Anyone interested in the health of the project Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 23 / 54
Some areas of interest Performance (understanding activity) Company participation (beyond copyright notices) Transparency (available information) Auditing (certify participation, experience, etc.) Profiling (key people, companies) Neutrality (fair treatment) Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 25 / 54
Some reviewers are more equal than others http://blog.bitergia.com/2015/12/30/ some-developers-are-more-equal-than-others/ Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 27 / 54
Apache Pony Factor In words of Daniel Gruno: We [the ASF] created a term we have coined “Pony Factor” (because ASF is full of ponies, or people who think they are ponies). Pony Factor (PF) shows the diversity of a project in terms of the division of labor among committers in a project. Pony Factor is determined as: “The lowest number of committers whose total contribution constitutes the majority of the codebase” https://ke4qqq.wordpress.com/2015/02/08/pony-factor-math/ Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 30 / 54
Bitergia Elephant Factor Projects can benefit from powerful collaborations from companies (elephants). The elephant factor shows the diversity of a project in terms of the division of labor among companies (by mean of developers affiliated with them). Elephant factor is determined as: “The lowest number of companies whose total contribution (in commits by their employees) constitutes the majority of the commits” Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 32 / 54
Code “owned” The code changes over time. The current version is “owned” by the people who produced it. The code “belongs” to those who wrote it. Zapata factor (work in progress): “The lowest number of developers for whom the total number of lines of code they “own” (were last touched by them) constitutes the majority of the lines of code” Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 34 / 54
Diversity: Code “owned” [Linux kernel, July 2016, Zapata factor: 200] Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 35 / 54
Code “owned” The code “belongs” to companies who employ developers changing it. United Fruit factor (work in progress): “The lowest number of companies for whom the total number of lines of code they “own” (were last touched by their employees) constitutes the majority of the lines of code” Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 36 / 54
Issues may be processed not as intended Policy (or recommendations) may mandate transitions but are they real? Time to close when same company reporting / fixing? Time to close for external bug reports? Time to close depending on who reports? Who opens tickets that nobody cares about? Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 39 / 54
Geography Geographical diversity is difficult to assess Companies can keep detailed records, but open communties are different Fortunately, some tools leave traces... This allows for better knowledge ...and better tracking of initiatives Example: policies to enlarge the number of developers in XXX region Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 43 / 54
Gender: Analyzing by name Current situation of gender imbalance in OpenStack Gender Developers Commmits Commits/devel Female 750 14,647 19.5 Male 4,632 207,112 44.7 Only names with more than 80% of certainty. [Work in progress, preliminary results] Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 46 / 54
Gender: Analyzing by name Commits by women: 6.8% (4 Kcommits) Women: 9.9% (330 developers) Linux kernel, Nov 2015 – Oct 2016 Jesus Gonzalez-Barahona (Bitergia) Open Development Analytics Paris, Nov 2016 47 / 54
