Successful integration and practice of systems engineering within a business environment requires a wider knowledge and understanding of the strategic management and business processes of the organisation and wider enterprise. Spanning a wide range of individual disciplines, enterprise management is used to ensure that all business activity is planned, managed and delivered to achieve strategic aims, objectives and goals.

The interdisciplinary nature and wide-ranging applicability of systems engineering means there are inevitable touch points and integration requirements to ensure the enterprise can continue to deliver and meet its overarching goals and requirements.

This module critically examines the relevance of underpinning theories and practice across the enterprise management domain from a systems engineering perspective. Taking a capability- and effects-based context, it aims to provide the systems engineer with extended knowledge of the wider business environment within which the systems lifecycle sits, and how systems engineering application itself requires systems thinking and practice to successfully integrate it within wider business and management processes and approaches

As products, services and solutions become ever more detailed and interconnected in their nature, ideas of complexity become ever more important in understanding the structure and behaviour of these artifacts. Moreover, as these artifacts are required to alter and adapt to changes in requirement, use and context, it is important that a means to allow them to be adapted as rapidly as possible is considered during their development and use lifecycle.
