الوصف: In this paper, an application of cyclomatic complexity to enterprise scale is proposed. Enterprise architecture frameworks are introduced as a standard way to document enterprises. A specific enterprise architecture framework is selected for the implementation of the proposed cyclomatic complexity application. A candidate implementation shows how the cyclomatic complexity of an enterprise documented in an enterprise architecture framework is estimated. Results from manual analysis of the enterprise elements comprising enterprise cyclomatic complexity are compared to results of the proposed extension, showing the two approaches are equivalent. The method is applied to U.S. Army application showing the ease of the practical use. The result is a tool for enterprise architects to easily assess the complexity of enterprises of interest.

الوصف: Enterprise system engineering (ESE) is a practice emerging in the last decades, aiming to support the enterprise systems engineers in generating and developing enterprise architecture and improving enterprise operational processes. However, ESE differs significantly from systems engineering (SE) due to the enterprise's unique property as a system of unsynchronized arrays of systems. This property might lead to severe issues, such as cross-enterprise failures, lack of decision-support information for cross-enterprise decisions, long delays in integration tests, and unexpected emergent behavior. Enterprise Processes Integrative Collaboration (EPIC) framework is an ESE framework, aims to address this property by generating better coordination between unsynchronized arrays of systems within the enterprise and even further across several enterprises. Previous research dealt with the validation of this framework by implementation in two large-scale enterprises from the aerospace and transportation disciplines. The objective of this study was to verify the EPIC framework completeness and integrity, as an example of ESE framework verification. A model-based SE methodology was used to encapsulate EPIC, defining the ESE activities, required resources, and products. This encapsulation allows tracing the engineering activities, verifying the model completeness, traceability, integrity, and interoperability of the ESE processes collaboration.

الوصف: As engineering projects grow in complexity, estimating the required engineering effort during the development phase of a project has become more art than science. Predictions of required engineering effort are based on empirical models fitted to historical data with additional subjective factors, such as “team cohesion,” applied based on the judgment of the user of the model. Recent work has shown that information quality theory can be used to estimate the engineering effort necessary to develop system requirements by evaluating the change in requirements uncertainty during the requirements engineering process. This paper builds upon that foundation by generalizing the information quality theory to apply to the variety of system engineering artifacts generated during the development phase of a program. The generalized form of information quality theory is implemented in a model for application to the system architecture definition process. Engineering effort required for system architecture definition on four programs is used to evaluate both the performance of the model and the performance of the system architecture definition teams. The results of the model and program evaluations show clear benefits in reducing the engineering effort required to define a system's architecture when there is reuse from previous programs. The results of the evaluation also show the architecture definition team benefits from “momentum” and performs more efficiently if the team has completed a system's architecture definition on a recent program.
