In this research article, System of Systems Methodologies framework has been extended in order to propose that System Dynamics approach has the capability to model and simulate the aspects of System of Systems. It, therefore, invokes a new concept of System of Systems Dynamics in the literature. Then, in order to perceive the practical implications, a case study account of a textile weaving organization has also been demonstrated. The organization under consideration had high cycle time due to unnecessary work in process, and reduced production capacity because of rolling blackouts. The study was conducted to model and modify the existing scenario intended to put forward a preferred future scenario. The proposed future state was constructed using selected Lean tools required to address the ongoing concerns. In order to realize the prospective Lean scenario, a capital investment model was run in relation with the setup developed to carry out capital budgeting for multi-fuel captive power plants. System of Systems Dynamics in the presence of lean concepts proved to be an intuitive and comprehensive approach for making strategic decisions. The model can serve as a planning tool to evaluate the financial impact on the overall profitability of the company under consideration.
