Originally coined by Tim O'Reilly in 2000, the concept was reintroduced by Dennis Cooper in 2015 as organizations faced increasing digital transformation challenges. The rise of cloud computing and digital transformation led to more IT resources, engineers, and products within companies, creating organizational silos that InnerSource methodologies help break down. The InnerSource Commons Foundation serves as a neutral hub for organizations adopting these practices, providing patterns, case studies, and community support. The approach emphasizes four key principles: openness (accessible resources), transparency (open decision-making), prioritized mentorship, and voluntary code contribution. ## 🗒️ Notes #### ⏱️ [00:00](https://youtu.be/XdiXkcwLyiM?t=0) — [H1] 10th Anniversary Celebration - Key idea: InnerSource Commons Foundation celebrates 10 years alongside 25 years since the term was coined - Evidence: "It's actually 25 years since the term inner source was coined by Tim O'Reilly" #### ⏱️ [00:30](https://youtu.be/XdiXkcwLyiM?t=30) — [H2] Global Partnership Recognition - Key idea: Multiple major tech companies sponsor and support the InnerSource movement - Evidence: "Analog devices, Vurgia, GitHub, IBM and Microsoft and Bosch, Comcast" #### ⏱️ [01:15](https://youtu.be/XdiXkcwLyiM?t=75) — [H1] 24-Hour Global Summit Format - Key idea: First-ever 24-hour summit spanning Japan, Berlin, and New York - Evidence: "This event is 24 hours event.

So New York will be New York [01:32] summit will be operated by um IBM. So [01:35] and also there is uh another uh summit [01:38] dedicated sponsor GitLab, Red Hat and [01:41] Bird Solutions. Uh thank you very much [01:43] and for supporter is Nifty. So please be [01:47] ready to be taken uh by so actually we [01:50] are sharing uh this kind of excitement [01:52] uh afterwards. [01:54] So um I'd like to hear uh introduce [01:59] about the foundation itself and why [02:03] inner source matters right now and then [02:06] actually I will briefly touch on AI [02:09] relation of inner source. [02:12] Yep. So as I said that actually Inosour [02:16] stories are everywhere. So we they are [02:19] building their innoc [02:21] culture, Inosour program offices inside [02:24] the company. So from the financial [02:26] sector, manufacturing sector to cutting [02:29] edge technology or maybe big tech. So [02:32] actually and then there are several [02:34] Japanese companies uh cases available [02:37] here. So please visit [02:39] innerossource.orgstories. argstories [02:44] and inner source community across the [02:47] world is very very exciting thing. So [02:50] from uh Europe, America and Japan and [02:54] China actually we have several guests [02:56] from uh Apac region from Thailand and [02:59] then China. So actually uh please enjoy [03:03] those kind of global session as well [03:04] today. [03:07] So and actually Inosource itself is also [03:12] uh growing and exciting. So Inosource [03:15] the term is captured in Gardner's hype [03:18] cycle uh two years ago and then actually [03:21] Gartner's uh Nitish Thiagi M principal [03:23] analyst will present the current status [03:25] of inner source uh today. So actually we [03:29] are gaining momentum and then also inner [03:31] source itself is very important uh topic [03:34] for driving AI adoption as well. [03:39] So I will explain it later. So actually [03:42] um our first summit was um conducted in [03:46] 2015. Um actually it was a closed uh [03:48] very private one. However, actually um [03:52] we have a very first summit in uh 2016 [03:55] and [03:57] um actually this year's summit is very [04:00] special because um this is 24 hours [04:02] format. So actually Japan is the first [04:06] um uh place for uh this summit. So [04:10] please enjoy. Actually uh you can also [04:12] join the new Berlin and New York summit [04:14] online as well. So please enjoy those uh [04:17] content as well. [04:21] Yep. And then actually u there is some [04:24] black boxes in the right bottom corner. [04:26] However uh there's a inner source man [04:28] here as well. So actually afternoon you [04:31] will see inosource hero in uh this uh [04:36] summit Yokohama venue but actually our [04:39] uh community itself local community is [04:42] also expanding. So starting from the [04:45] Dublin community actually we had a [04:48] formed inos gathering brand h in 2024. [04:52] So we had an event at Tokyo, Berlin, [04:54] Vienna, Dublin, Shenzhen, Paris um Sa [04:58] Paulo and then we are looking forward to [05:00] the African community as well. So [05:02] actually um you can join uh your [05:04] community in Japan of course if you are [05:06] in a different location you can join [05:08] those community as well as you can [05:11] actually found your community yourself. [05:14] So we are very looking forward to your [05:16] contribution [05:19] and actually recent highlight is China [05:22] and Japanese community growth. So in [05:25] China it's actually last year we had a [05:28] 10,000 um participants level online [05:31] event uh in it's actually hybrid event [05:34] and also last year and this year we had [05:37] an amazing Japanese uh community in the [05:39] gathering event. We will uh join [05:42] gathering event the uh next year as [05:44] well. So please stay tuned [05:50] and actually our mission is we empower [05:54] developers and organization to apply [05:55] open collaboration principle in their [05:57] daily work. It's not about only about [06:00] open source but for also for propri [06:03] proprietary area. So we build a strong [06:07] uh inclusive community and also we [06:09] should be a neutral hub as inner source [06:12] commons. So if you are willing to take [06:15] kind of inner source approach inside [06:17] your company. So please uh join our [06:21] community and then also uh probably you [06:24] can post something on uh slack or maybe [06:27] you can join the GitHub conversation as [06:29] well. Yep. So [06:32] now [06:34] probably some of you have may have known [06:38] about inner source and then some may not [06:41] know very well about inner source. I'd [06:43] like to explain a little bit more on [06:45] inner source what the inner source is [06:47] and why innosource matters. So actually [06:51] 2000 as I said Tim Oridi coined the term [06:54] Inosource [06:57] but since [06:59] the Inosource definition is like a [07:02] helping team and a companies to use open [07:04] source development technique within the [07:06] corporation with a cluster of key [07:08] customers. So there were some community [07:11] and there were some practitioner but [07:13] it's not unnamed or maybe it was just [07:17] taken as a part of open source and then [07:19] it was okay because there were not that [07:22] many silos inside the organization at [07:24] the time because actually um there are [07:27] IT resources just existing for [07:30] supporting their corporate business [07:32] objectives or maybe their mean core [07:34] businesses. However, in 2015, Dennis [07:39] Cooper, our Inos comm Foundation's uh [07:42] founder reintroduced inosource. There's [07:45] a why the reason because um actually in [07:49] 2015 what happened it was a cloud era [07:52] cloud I mean adoptions and every single [07:56] company are trying to be a digital [07:58] company by transforming theirself. So it [08:01] was called it was called digital [08:03] transformation and it resulted [08:07] every company's IT resources were [08:10] increased and also they are hiring they [08:12] hired so many engineer inside the [08:15] company and they created so many [08:17] products inside the company. So that [08:20] made silos and corporate silos in the [08:24] organization. So there were the reason [08:28] to drive the inner source cultural I [08:31] mean changes and also driving the [08:33] transparent culture inside the company [08:36] or maybe their uh reason to there were [08:39] reason to break down the silo across the [08:41] organization because they shouldn't [08:43] reinvent the wheel inside the company or [08:46] actually they need to share their um [08:50] corporate resources or maybe co uh [08:52] competitive resources across the company [08:55] because they are trying to they were [08:57] trying to create a synergy uh inside the [09:00] organization by co-creation. So that's [09:04] the reason why innosource matters [09:07] mattered at 2015 and then actually we [09:11] are uh thinking that innerource itself [09:13] is very important uh topics for AI as [09:16] well. So, so there are four principles [09:20] of um inner source openness uh [09:24] transparency and prioritized mentorship [09:26] and finally uh voluntary code [09:28] contribution. So openness and uh [09:31] transparency is a little bit different [09:33] because um openness is just open and [09:36] accessible but transparency itself is [09:39] for decision making. So if your decision [09:43] making is open and transparent and [09:46] conducted in a transparent way, it will [09:49] bring uh something new to your [09:51] organization. Probably your team or [09:53] neighbor team can start contributing to [09:56] your team or maybe you can easily access [09:59] to your corporate resources [10:01] um without any boundary. So open [10:05] transparency and also opensource culture [10:07] based prioritized mentorship and a [10:09] voluntary code contribution is very [10:11] important thing. Yep. [10:14] And actually the open-source [10:19] practices so it's kind of broad idea [10:22] right? So it could be anything. So it [10:24] could be for instance um just [10:26] contributing to other team or just [10:28] removing uh your configuration for [10:31] closed configuration or maybe you you're [10:33] opening up your repository. However [10:35] actually we were starting to um compile [10:39] those practices as inner source patterns [10:41] from 2020. So you can visit innerosource [10:45] patterns and you will find the idea what [10:48] the inner source is and how to adopt the [10:51] inner source methodology inside the [10:54] organization. So it's uh it's all about [10:58] the I mean organizational theory thing [11:00] and also culture change and then also [11:03] decision making processes. So it's very [11:06] uh I I I'd really recommend visiting [11:09] this site as well and there are so many [11:12] uh inner source books available. So it's [11:15] very uh great starting point to learn [11:19] inner source. [11:21] Yep. So this is innerource summit which [11:25] is a global flagship conference and then [11:29] actually we have a gathering event in a [11:32] different location as I explained. So uh [11:35] actually we have done three gatherings [11:38] in Tokyo but actually uh in Europe [11:41] regions and then American region there [11:43] are different one. So if you are [11:46] traveling to Europe or maybe America or [11:48] maybe other regions and then if you are [11:50] connected to Inosour um community yeah u [11:54] I I'd recommend that um you will join [11:57] the Inosour gathering or maybe [11:59] conference as well.
