- W2233200725 abstract "This thesis aims to improve the management of system development to deliver more affordable systems. Improving affordability is investigated from the avionics supplier’s perspective. An affordable system is defined as meeting customer needs for performance and lifecycle cost in an over-constrained program space where initial development budget, schedule, performance and lifecycle cost goals are not all achievable. In certain segments of the military avionics market, the nature of competition is changing from performance to affordability based. Firms that develop competitive advantage in delivering affordable systems can capture market share. This research is different than most literature published on affordability because it focuses on design innovation as opposed to product development and manufacturing efficiency through Lean, Six-Sigma or other techniques. Lean and SixSigma are necessary to improve system affordability but not sufficient to develop competitive advantage because they can be implemented by anyone on any system concept. Competitive advantage requires benefits from Lean and Six-Sigma and design innovations focused on affordability. Step function type improvements can be realized through system architecture and module design innovations that strike a better balance between lifecycle cost and performance. Four areas are investigated: the nature of development focus during each design iteration, the role of requirements, managing lifecycle cost as a design requirement and effective integration of downstream knowledge into the design. A model for developing requirements that strikes a better balance between performance and lifecycle cost is suggested – treating lifecycle cost as a design requirement and explicitly focusing on understanding the cost-performance trade space before developing requirements. A product development model is suggested – focusing on achieving lifecycle cost goals first and using iterations to grow performance can lead to lower cost solutions. Both the requirements development and product development models require leveraging prior knowledge, technology and capability. The requirements model requires high knowledge of system cost drivers and achievable performance. The product development model requires low technical risk allowing the team to focus on affordability first without running unacceptable levels of performance risk. Methods for increasing the effective integration of downstream knowledge are also discussed." @default.
