In numerous project management classes, building a team for a project is seen as critical. It may be the first thing you consider, even before selecting a specific project.
On the Linux-on-the-mainframe team, you will need people with the right mix of technology skills. This might mean that your team members come from different departments across the company. First, the team will need general IT skills in the form of good system management and control processes. This skill is independent of their technical background and can be provided by people with either a mainframe or a Linux and UNIX background.
Second, the team will obviously need someone who knows how to prepare for a Linux image on the mainframe. Skills that such a person might have include setting up a mainframe, operating it, partitioning it, defining I/O, and setting up z/VM or LPAR.
Last, but not least, the team will profit from someone who has Linux, or at least UNIX, administrator skills.
Apart from these skills related to the technology used, you will also need some skill in the area of the project chosen.
