A Principles Framework to Inform Defence SoSE Methodologies

Unewisse

2018

This paper outlines the development of a Program Integration and Interoperability Assessment (Program I2A) methodology. The methodology underpins integration and interoperability (I2) assurance through a system‐of‐systems engineering assessment approach used to undertake Program capability design, realization and management, and examination of the key artefacts. A scorecard approach was designed for the Program I2A. The methodology was tested on a complex Defence capability (Integrated Air and Missile Defence) and from the lessons learnt it was refined to generate the Program I2A methodology described in this paper. A notable feature of the methodology is that it inherently facilitates the delivery of a force that will be joint and integrated by design. In particular, it provides senior decision‐makers with evidence to gauge the effectiveness of the emerging Program and force‐level (SoS) approaches. In doing so it lays the foundations for a mechanism to facilitate the cultural changes needed to establish a joint‐by‐design approach to delivering integrated force capabilities.

An Austere SoS Integration Assurance Methodology

“…The above outlines the new arrangements and their implications for the design of Program SoSE approaches. In addition, the sets of principles compiled by Pratt and Cook (2017) and Cook et al (2013) were reviewed for additional high-level needs. Table 2 below distils these into a set of the most significant needs that can drive the design of Program-level approaches with the Australian Department of Defence.…”

A SoS Approach for Engineering Capability Programs

Unewisse

2017

The Australian Defence Organisation is undergoing the most significant change in 40 years to deliver a more effective and agile defence force. One of the key changes is the introduction of a new capability life cycle that seeks to take a more holistic perspective on defence capability. This has included the introduction of Programs that are to be managed in a coordinated way to optimize capability outcomes across a group of Products and Projects. The paper opens by discussing the context in which Programs will be implemented and identifies the needs for their management and systems engineering. The needs analysis concluded that a system‐of‐systems engineering (SoSE) approach is needed and that this should be tested and refined using an initial test case. Building on recent review material of SoSE approaches, a modified wave model was selected for the test case as the preferred approach for Program SoSE. The paper concludes with a set of recommendations on how the initial test case should be implemented to provide a foundation for broader implementation across Programs.

“…The culmination of this work has been the identification of key SoSE principles and development of a philosophical hierarchy within which to structure them. While a detailed paper on this framework has been produced for CSER (Pratt & Cook, 2017), a summary is provided here for context of the subsequent discussion on its usage.…”

“…This work is motivated by the desire to provide some structure and traceability in the process of designing SoSE methodologies. Initial typology work (Cook & Pratt, 2016) has been published in the 2016 IEEE SoSE Conference and the more detailed principles hierarchy (Pratt & Cook, 2017) at the Conference on Systems Engineering Research (CSER) 2017. This paper provides follow-on work that describes the proposed process to validate the principles and how the principles can be utilized by practitioners.…”

An overview of previous work by the authors follows describing the three-layer framework used to hold the SoSE principles (Pratt & Cook, 2017) to provide context. This framework comprises an articulation of the worldview which makes SoSE meaningful, the concepts that drive SoSE methodology design and use (descriptive heuristics), and implementation principles (prescriptive heuristics).…”

Using the SoSE Principles Framework

Pratt

2017

This paper is concerned with the principles for successful System of Systems Engineering practice and their use. The paper opens with a description of the need for System‐of‐Systems Engineering (SoSE) within the Australian Defense context and the research underway to support its introduction. An overview of previous work by the authors follows describing the three‐layer framework used to hold the SoSE principles (Pratt & Cook, 2017) to provide context. This framework comprises an articulation of the worldview which makes SoSE meaningful, the concepts that drive SoSE methodology design and use (descriptive heuristics), and implementation principles (prescriptive heuristics). The paper discusses the need for substantiation of these principles and the framework, the methods by which this being conducted and some the initial work assessing coverage and applicability. Finally, the paper provides suggestions for how this framework and associated principles can be employed for its stated purpose (utility), with specific regards for different stakeholders and their varied roles and responsibilities.
