I think all the factors listed are very important for a project, and I think the most important thing is to Develop clearly defined plans with assigned responsibilities. For each task in thee project must be identified in your data management plan, and identify the skills needed to perform the task. Also, I think a successful data management plan requires that the appropriate staffing resources are available and trained. Also identifying specific tasks and responsible parties will help with budgeting, implementation, and preservation of the data resources.
