It sounds like we recently discovered that there is a separate project working on similar technology. It would be a good idea to touch base with them, and talk through these issues to make sure we are on the same page. Ideally we should have some answers to the following sorts of questions: - Do the two projects overlap or do they provide unique functionality? In what areas do they provide unique functionality? Are there opportunities for the two projects to further converge? - What kernel groups does the other Device Management project have a relationship with? Is it the same groups as the ones you are working with? If not, does this mean your group should develop a closer relationship with these other kernel groups? - It would be handy to have a better understanding of the pros and cons of the two applications and to have a more clear story about why having both adds value. You say above that you will only contact the other kernel groups if necessary to move the project forward. How do you know if it is necessary without first contacting them? I would think we would need to learn about the requirements of the other Device Management project to understand how this project fits in. To do this, isn't it necessary to develop a dialog with them? There have been some situations within Sun where projects have gotten canceled because there was a competing project that did the same thing. You reduce the risk that your project will eventually get canceled if you make sure that you start dialogs early when you discover there are potentially competing projects being worked on by other teams within Sun.
