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” Let’s do it! Jesus Gonzalez-Barahona (Bitergia) The Grimoire system for software development analytics FCM2 2014 8 / 35 

But data has to be extracted, mined... Data lives in repositories not always designed to release all their data easily: tools are needed to retrieve and extract it Data includes many complexities and details tools are needed to filter, organize it Jesus Gonzalez-Barahona (Bitergia) The Grimoire system for software development analytics FCM2 2014 9 / 35 

But data has to be analyzed, visualized... Casual observation is not enough: tools are needed for statistical and other kinds of analysis Analysis is not enough: tools are needed for interactive visualization Jesus Gonzalez-Barahona (Bitergia) The Grimoire system for software development analytics FCM2 2014 10 / 35

Why open development analytics? Jesus Gonzalez-Barahona (Bitergia) The Grimoire system for software development analytics FCM2 2014 27 / 35 

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) The Grimoire system for software development analytics FCM2 2014 28 / 35 

Open development analytics Who is interested? Large & small free software communities ...and thousands of large & small companies, public administrations, foundations participating in them, depending on their software [Who can afford not to be interested? It is a key strategic need for many actors] Jesus Gonzalez-Barahona (Bitergia) The Grimoire system for software development analytics FCM2 2014 29 / 35 

Open development analytics Why? Free software produced with open development models is more and more important for IT users, producers, integrators It is different & complex, yet transparent, many details are public, and it can be improved Jesus Gonzalez-Barahona (Bitergia) The Grimoire system for software development analytics FCM2 2014 30 / 35 

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) The Grimoire system for software development analytics FCM2 2014 31 / 35 

Can we conclude something? Jesus Gonzalez-Barahona (Bitergia) The Grimoire system for software development analytics FCM2 2014 32 / 35
