Explanation
The most important aspect of system development methodologies that the engineer is likely to discuss with the director of field support is how the system model can be used to facilitate change proposals, support plans, and training in the operational environment. The system model can provide a consistent and comprehensive view of the system's structure, behavior and performance throughout its lifecycle, and can help identify and evaluate potential changes, improvements or issues in the field. The system model can also help document and communicate the support requirements, procedures and resources for the system's operation and maintenance.
The system model can also help design and deliver effective training programs for the system's users and operators. How field support operations can be modeled using MBSE methods, how software design patterns can be used to suggest Pre Planned Product Improvement (P3I) opportunities, and how operational evaluation (OPEVAL) plans can be developed and cross-checked in a system modeling environment are less important aspects of system development methodologies that may not be relevant or applicable to the director of field support's concerns.
