Developer Summit 2012 in Kansai
The DeveloperSummit was a free one day conference (in Japanese) for developers held in Kobe, Japan. It is nice to see more of these events taking place in Kansai rather than just in Tokyo. This event was very popular with several of the sessions being completely full.
The keynote presentation was from Oikawa Takuya, one of the Japanese developers on the Google Chrome team. The main theme was the changes in project management style required when developing for “the cloud.” Out is the old style product lifecycle with releases every few years and in is the “versionless” development with very frequent or “continuous” releases. Also, the use of open source and the challenges that brings to development when contributions from many people must be integrated. This was an interesting presentation giving some insight into the how Google develops some of its software and Chrome in particular.
The first presentation on the “Agile” track was from a Microsoft evangelist entitled “Continuous value delivery to the next decade.” This presentation also discussed the differences between waterfall and agile development and how development is done at Microsoft. However, the whole presentation seemed like an advert for TFS. The main point seemed to be the advantages of using a single tool for project management, bug tracking version control etc rather than several different tools. And Microsoft just happens to have such a tool. This seemed to me like agile for those who want to say they are doing agile but don’t want to change too much. The process seemed to be more like a series of mini-waterfalls backed up by comprehensive tools.
Following the Google and Microsoft promotions we had an advertising spot for JIRA (the bug tracking system from Atlassian) given by Suzuki Yusuke, an engineer from Growth xPartners which seems to be an Atlassian partner in Japan. This was less a less subtle promotion since the presenter even included a price list for JIRA in one of the slides. After yet another description of waterfall and agile processes (the third so far) the presenter stressed the importance of collaboration and communication in Agile development. I would not argue with that, but I am sure that there is more to communication than a bug tracking system. The middle part of the presentation described how “Agile is implemented in the bug tracking system.” The idea seems to be to use JIRA to hold the list of tasks to be done and to act as the communication medium for the team.
We use JIRA as a bug tracking system and it seems to be one of the best bug trackers available. However, I often see it as blocking rather than enabling communication. Instead of direct communication between individuals, communication is via comments on an issue. This leads to misunderstandings and delays. Also because it is so easy to create an issue the “backlog” quickly becomes an unmanageable black hole into which requests and improvement suggestions are sent to be forgotten.
I suppose that not surprisingly, from a company selling the bug tracker there was no suggestion that the use of a bug tracker is itself actually a symptom of a bigger problem. A truly agile team would probably have no use for a bug tracker.
The presentation that I was most looking forward to was that by Wachi Yukei on “The evolution of test driven development.” He is one of the translators of “GrowingObject Oriented Software Guided by Tests”, the Japanese version of which was just released on the same day as the developer summit. This presentation gave an overview of GOOS. The description of Mocks was fairly hard to follow and my Japanese colleagues who were not familiar with mocks did not seem to understand it at all. Actually the biggest problem seemed to be the direct transliteration of English expressions into Japanese, such as “walking skeleton.” This is not a problem for me as an English speaker – in fact it makes it easier – but makes it hard for non-English speakers to understand. However, the presentation did include a lot of good stuff from GOOS such as the need for end-to-end tests and thin slices of functionality. I am not quite sure on the relevance of the photo of David Cameron.
Many of the presentations are on SlideShare (in Japanese)
