Talk: Identifying Metrics to Communicate the Value of Open Source Contributions

A

A

A

A

So when we bring this up by organization, greed or commits prawns both in please, it seems creative audience why this happens. The two hundred meters that are running this project or a number two beautiful companies, went on to better jobs elsewhere.

A

So you might think both great in solve this problem, but it's not actually case and that's because individual metrics imperiously, we need a more holistic approach that provides better the finest things about the entire ecosystem. My goal here is to build in this afterwards that solve specific problems so and I'm going to convince you by the end. This talk this one point with that can do it by running to developing a seems like long term trend lines, there appeared a celebration by the contributor distribution in terms of evaluating.

B

The organizational.

A

Distribution in a very similar manner, I'm gonna show you some examples from these two products will auto driver was started by any Wells we've everybody off in the names, don't matter so you can just think of them as.

A

That's the first building case get accelerates from the left cumulative on the right with project yellow. You can see that there was this very sudden acceleration that been outdoors in a sustained rate of development, and this results in new developments that raises the journalist what happened here to essentially both ever increase and increase sustained still sustained versus project purple, where there has been a very estate development lease over its lifetime.

A

Despite bringing the fluctuations near here, so a might be slower, one meter fast the next year. Overall, if he's actually very consistent. Now, let's look at revenue.

A

There were multiple persistent periods of deceleration, rather sister, eventually made across below this trendline after spending will be near about that trend. In fact, you could look at that and see that the privileged I might recommend. So what could you learn for this? Consider? This project had consisted of deceleration, though each one of those periods to the triggered some sort of long further analysis on this one. Additionally, the cumulative commits dropping much bigger alarm, because that project should be.

A

On to you, contributor distribution, so this is a office on the left because in the bottom figure the bar. That means that author has a few more commits project. You can see it's very, very populous and it has a very strong dependence on particular developers and no one else is going to very mid-sized, be very subtle contributions versus profit purple, which has a much much more, even distribution from its father, so much so that there actually is a sort of curve here, rather than just straight lines.

A

In fact, this bucket, we look at individual contributions over time. Purple has rainbows and.

A

Yellow is community, so then we look at this distributed over time zone and this is a picture of looking at liberal authors, the fertilizer, so for this particular project there there are those two entertainers. There are American single variables, which just happens to be the less posters from our offices and those contributions when you're looking at it based on commits per time zone. You can see it's very honest that was very coming primarily from T right here.

A

He knows, but purple, on the other hand, has some get misdemeanors in multiple of these rooms, so we had nominee a lot and West Coast bar offices, but there's a company in Japan that actually- and that's.

B

Also reflected.

A

In commits per time soon, there's a much greater diversity domain commits.

A

So let's take a loop from that look at the a pencil once again, we look at any contribution is progress over time, there's roles of contributors that we're not the primary developers throughout projects history, so people are showing up making contributions to this project.

A

However, the offered distribution is still very, very topical. This depends very much on see law.

A

But there are already numerous contributors in that first team applications, good reenactment problems about making websites for international audiences, so it makes.

B

Sense that there's.

A

A lot of people participating I think this part is the most important to school analysis, because it shows that there actually is the opportunities for this project all over the world. A liver.

B

Is dominated by.

A

Continents problem tuning voltages for members, so what we learn from this record low caste history and contributions from verse. However, most people never mediate, wouldn't want contribution.

A

Last means a small distance, so once they get it blinking at both verses.

A

This circle is polite. Ingredientes of blue is not the outer circle of individuals, so bigger all the time is blue. That means, as you can see, not fortune is very visible.

A

Additionally, if we look at the commits as a percentage over time, you can see that as time, moves on the expertise for contribution is marked as a versus product purple, where there is the more diversity in terms of not all the community. In fact,.

A

Median size has been consistent and what's the game as a percent over those extra contributions articles so when you're launching a project the next one around it. This is a very good start to see. Is that meanness we're getting more and more confirmation of the concept?

A

So let's look at consultants again, so for them the extra contributions are the modest portion of the total contributions. I. Don't really think this is good, it's just it where it is, there's double a grouper, but there are extra involved Acosta's. The word for deleting those external contributions are increasing as a percent.

A

So what we've learned here, they react himself at an increasing rate of participation relative to image, however, that X from position never reached a certain critical mass words sustainable from water. So I would say this project came easy.

A

So, let's start looking at Walters, so, like I said there are numerous contributors around the world.

A

Really are given to someone else that, when you're doing s value additionally, those participants were regular there throughout the lifespan of this project, so they were wolf opportunities to reach out to these new contributors to increase their quality and then finally, the as I mentioned, the external contributions are increasing.

A

So if I had to summarize how to say this bucket in one slide distance make this chart, those shows for time zone he's always been a contributor. Look like this turn long, so bringing more equity in terms of poverty contributions.

A

The distribution of offers.

A

So more detail out of Satan's one evaluate the individual and organizational situations to identify where topography and instances to identify the internal experts bridge them with participants. We no longer happens.

A

Then finally settle learns to notify the authorities when certain events professional footballs- this is for emergencies Zoe. When this project cost this trendline it was oriented. So at that point it should have true that a very masculine says this is an emergency.

A

The Pilatus there is actually still being two people that are trying to contribute: vocals profit, greatly initiative bus. We are regularly getting forward twice, there's just no, so it's not actually.

A

So what does this be? This will you know so well, here gathered.

A

Solar for specific boomers to do this, we need to use the right dated better to be big later, how shouldn't be directed to solving problems with the event mention sex like his actually breathe in school, for my native individuals, but any call the manager the manager just want the program office lever, there's a lot of people that would find documents and I were just wearing them together with all the weirdest. Almost so I haven't published all the dashboards. That I think this.

A

They're, all building from our lab and I've set it up so that it's very easy to just get doctors most company machine, basically just my operative most you have is out of blood more people to help me out to find out. You know what are the problems we need to solve on these events.

A

Are these dashboard support and by the way, I'm more than willing to practice projects? There's not a whole lot of data resources there right now, but it's ready.

A

I need your help to make this possible, so some of the things that I still need to figure out is what's the best way to classify these. That's why the Queen eyes expensive. So let me do a question. We have a dashboard set to say a community manager for a software, public manager, architect or a focus for this.

A

You know maybe identifying your words to find events or something like that, or they would do both it just but like users, because she is which ones are most viable to them. What other metric says would be useful for honoree viral complementary, so this could be things like setting up a dashboard monitoring, develop a backlog to make sure that only the people that you murdered developers are dedicated towards resolving these problems, keeping up with tomatoes we're making looking at individual overs. So.

A

Other says: help identify and solve specific problems.

A

So you know we noticed that there's a company in Japan participating these projects, that's a company that we get out reach out, students, fight those comes with a partnership, so that would kind of mean to even share different things. But I was willing to identify any sort of project. So is it dis? Dependence is development increasing over time, because not always a bad thing.

A

Sometimes editors, there won't be a the bun I play better than buying data sources, so you produce more c'mon things about music, so my club just focused on on get commence, and that was just primarily because I had limited time frame, house kind of fertility, some information for this product, what I'm mortgages in the interaction among these days. So what are the effects of letting advance small games life developing days? The distribution of contributors, organizational.

C

A

C

B

A

To Maxim have data that shows your bank.

A

So that's it Nuggets. We have about four minutes for questions.

A

So a lot of projects yellow this earning wall doing this I have to identify these sacks.

A

And now now we actually have a understanding of music boxes. Assisting the house has passed so I think.

A

C

A a two point one will take second, is that.

C

It seems to trigger and what I've seen so modest, almost every one of those projects as soon as independent efforts following he completes that some inspiring.

C

But it seems, and peacekeeping faithfully squash, it seems like I think that you would connection cane is power so and.

A

Then it's built on mind. Would society depends you see this pipe burst and activities that is that actually sustaining something in or those eighteen aviation first occupation of that event, did they come back for a second one, because that it is but often just in the tiara? So that's that's exactly what about the new tracks. He said it was going.

C

Anywhere they have basic fix, it seems to be because this company and I know I seen you I know to be wrong.

C

So, let's see if we change.

A

A

Didn't talk to developers around this project indicated to be that very well that you sold a lot of people bug, fixes and features the primary reason.

A

No one is going to step up and say it's mine.

A

Sometimes parties just do they mature, there's, no.
