Systems Engineering has long been advocated as the way to address the ever-increasing complexity of engineered products and services.  However, shortcomings of current SE methods hinder our abilities to fully manage the significant social and technical issues that arise throughout the design process.  Document-based approaches often suffer from difficulties in maintaining and sharing information between disparate databases, spreadsheets, and users. Similarly, current SE approaches that focus on distributing and then meeting performance requirements are often subject to significant cost and schedule overruns, among other issues.  In order to overcome these obstacles, the future of SE should be Model-Based and Value-Focused.

Model-Based Systems Engineering

A model-based approach to Systems Engineering involves Potential stakeholders in MBSEexplicit modeling of the relationships between system components, as well as stakeholders.  It seeks to improve the efficiency and effectiveness of SE processes through the principles of formal modeling and automation. Current research in model-based approaches to systems engineering  include investigations of dependency management, the descriptive modeling of complex systems, and development of model transformations to automate workflow and reduce possibility of human error.

Value-Driven Design

Value-Driven Design provides a basis for rational decision making in engineering design.A value-driven approach to Systems Engineering involves taking a holistic view when analyzing the system of interest.  It seeks to improve the effectiveness of SE processes by advocating the consideration of stakeholder utility and relies on the theory of decision making under uncertainty. Current research in Value-Driven Design of engineered systems focuses on developing more efficient methods for specifying and solving value models for a variety of types of systems.
