We have a project and are about to add a new piece of functionality to otherwise stable codebase without any major changes going on except defect fixing. The plan is not develop the new feature separately for a while (probably a month) doing intermediate builds and testing and as the feature is finished and the quality is acceptable merge the code of the new feature in the main branch.
The question is what of the following two scenarios is better in terms of Clear Case:
1) Creating a new project based on a baseline in the integration stream of the current project, developing the new feature in this separate project with intermediate deliveries to the integration stream of the new project and build from the integration stream. And eventually delivering the changes from the integration stream of the new project to the main project (to dev or int).
2) Using a hierarchy of streams in the main project: creating a child stream of the integration stream in the main project (lets call it temp_int) and a child stream of temp_int (lets call it temp_dev). Developing the new feature in temp_dev, with periodic deliveries to temp_int and builds from temp_int and then delivering the new feature from temp_int to the main integration stream.
Thanks
