The matrices in the downloadable Excel file above define the subject matter experts (SME) identified throughout the Guide and describe the role that each SME performs on the NBS implementation project. There are two tabs in the file. The information in the first tab is organized by personnel resource, and in the second tab by task. The project manager can use this tool to allocate resources for each step of the project. SMEs can use this tool to identify the sections of the Guide that discuss activities relevant to their areas of expertise quickly.
