2. Agenda • Introduction • SW analysis • OT analysis • Recommendation • Conclusion
3. 1. Introduction • 1.1. What’s the software? • 1.2.1. The Conventional Software • 1.2.2. The Open Source Software • 1.2.3. Hybrid Software
4. 1.1. What’s the Software? • The software is important for computer. • Computers generally consist of hardware and software. Software
5. 1.1. What’s the Software? • Software is distinguished between “source code” and “runtime (binary)”. – The source code is used for programming, which is readability format. – the runtime is converted from source code to numeric, it easier to execute on the hardware. Source Code Runtime
6. 1.1.1. What’s the Conventional Software? • The Conventional Software is sometimes called to as “closed software” • Runtime only, no source code. • Strict user license.
7. 1.1.2. What’s the Open Source Software • Is called “OSS”. • Source Code (and sometimes with with runtime). • Free modification, free make new brand. Minix Linux Android OS EMUI (Xhaomi) EUI (HUAWEI) Chrome OS Fire OS (Amazon)
8. 1.1.3. What’s the Hybrid Software • Hybrid Software is a combination of the Conventional Software and the Open Source Software. • Runtime (and sometimes with full or a part of source code). • Restrict license (Multi licenses or Dual-Licenses). Customised
9. 2. SW Analysis • 2.1. Strengths • 2.2. Weaknesses
10. 2.1. Strengths • 2.1.1. Costs • 2.1.2. Reliability and Quality • 2.1.3. Development
11. 2.1.1. Costs • It can be used for free or very cheaply. – However, In general, it is required high skill for engineers. • It is particularly advantageous when used in large quantities. – Sujain (2017) states that Facebook has 1,800 Database servers with three engineers.
12. 2.1.2. Reliability and Quality • According to Vinay – in general the Open Source Software was more problematic than the Conventional Software and it was thought that it was low quality. • (Because someone can be modified?) – However, it has been confirmed that famous Open Source Software such as Linux has less issues than Conventional Software. • (The some reasons that anyone can investigate the source code, finally, it is required a review for a modification with community.)
13. Linux
14. Android
15. 2.1.3. Development • The Open Source Software develops in a community called mass collaboration. If they are a large community and active, development will continue. – Necessity-oriented. • On the other hand, the Conventional Software is fully developed at the discretion of the owner company. – Business-scheme-oriented.
16. 2.2. Weaknesses • 2.2.1. Responsibilities • 2.2.2. Confusing • 2.2.3. Responding to Closed Logics
17. 2.2.1. Responsibilities • The owners of open source software are usually not companies. – Most of them declare that they do not take responsibility. It means “At your own risk”.
18. 2.2.2. Confusing • Open source software is easy to generate variations. – For example, some various Android smartphones. • Usability is different for the same Android OS, same version.
19. 2.2.3. Responding to Closed Logics • Representative closed logics are patents. • The Open Source Software is difficult to coping with patents. – patent specification-related specifications and source code are not disclosed. – It may be required to pay the patent fee.
20. 3. OT Analysis • 3. OT Analysis
21. 3.1. Opportunities • 3.1.1. Transparency • 3.1.2. Business • 3.1.3. Job Engagement
22. 3.1.1. Transparency • Ben (2017) states that the Open source software is highly transparent. – Everything (such as source codes, issues, specifications) is open to the public. – The correspondence of ease to the issues and potential threats. – The most of the discussion and actual processing such as implementation are open to the public, and anyone can follow it as a history.
23. 3.1.2. Business • In recent years, the platform based on open source software is extremely increasing. – For example, Python has a large share for AI and big data, Linux is spreading for could environment such as AWS (Amazon Web Service), Chrome and Firefox are for major OSS browser. • According to Statista, the Open Source Software market was 7,924 EUR in 2008, 559 EUR in 2018, which is 8 times bigger.
24. 3.1.3. Job Engagement • According to a survey of ChallengeRocket (2017), all programming languages out of the top 10 high-salary programming languages are open source software. This means that if you aim for programmers, open source software programming languages may have higher revenue potential.
25. 3.2. Threats • 3.2.1. Change Licenses • 3.2.2. Communities Management • 3.2.3. Patents
26. 3.2.1. Change Licenses • If you choose open source as a freely usable software, you need to pay attention to changing the license. – This issue usually increases the license condition on usage. – For example, In the past, open source software with many users, such as MySQL by MySQL AB and React by Facebook, changed the license. • their users and communities are confused.
27. 3.2.2. Communities Management • Maintenance of open source software will be stalled if the community cannot work well. – New version may not be released. – New open source software may be established based on that open source software. • Jonas states: – the OpenOffice.org, which is famous as an open source office suite, • The community was stalled. • It divides into Apache OpenOffice and LibreOffice and has caused somewhat confusion in the market.
28. 3.2.3. Patents • In many cases the community is engaged in the development of Open Source Software, it is very difficult to deal with patent related issues. • According to Stephen (2008): – Linux OS infringed 235 cases from Microsoft's patents. – The Samba project dealing with Windows file sharing conflicts with several patents and they partnered to resolve it.
29. 4. Recommendation • 4.1 To be incorporated • 4.2 Using modern development method • 4.3 Make multicultural and various career community
30. 4.1. To be Incorporated • If they are over a certain size they will incorporate the community. – Strengthens project management and becomes a force to counter external threats such as patents. – Also serves as a challenge to larger markets.
31. 4.2. Using Modern Development Method • They will leverage better project management methods such as Agile development method. • Agile development method is one of effective project management methods for proceeding the project toward unstable goals.
32. 4.3. Make multicultural and various career community • The Projects that multinational people and people from various professions participate are effective. • People with various perspectives can see the problem from multiple viewpoints by participating. • As a result, – it can be improving correspondence to very difficult issues such as patents and internationalization. – it can be improving special environments such as translation system with common glossaries in translation environment.
33. Conclusion • The Open source software is an indispensable existence and it does not destroy conventional software. • In addition, new forms of software are increasing in combination with the concept of the Conventional Software and the Open Source Software. – As a result, every company and community will develop these forms of software for various purposes.
