Further improvement ideas for the pattern:

Previous PR with some further info about these topics:
https://github.com/InnerSourceCommons/InnerSourcePatterns/pull/245

Topics:

• Title / URL - a shorter title
  • Why? A shorter title would make it easier to reference the pattern (e.g. from other patterns), and shorter titles also look better in the table of contents in the book :) It would also lead to a shorter URL (the URL is actually depends on the filename, rather than on the Title of the pattern)
  • Ideas: Current title is "Transparent Cross-Team Decision Making using RFCs". Some ideas for shorter titles "Decision Making using RFCs", "Internal RFCs"
  • Last Feedback from Pattern author: Looks like this was discussed in the Patterns group and you're happy with it as is?
• Sketch - Any type of visual that can be added to the pattern
  • Why? Any visual makes the pattern look prettier in the book. Of course it is nice if the visual also helps to understand the pattern.
  • Ideas: Could even be a screenshot of the RFC template? Or a screenshot of one of the RFCs from RUST or elsewhere?
  • Last Feedback from Pattern author: I was thinking about an image of the template, but I think text is better as it can be copy + pasted. Perhaps a process flow diagram would be good?

先閱讀連結的 pattern，以及 pull request #245 中的討論。向 pattern 作者確認標題是否應變更，以及需要何種 visual（如果需要）。當約定的標題和 visual 指引已納入 pattern 後，即表示完成。
