Quality Assurance methodology for system requirement definition

Abstract : Companies are competing to put their products on the market. In this race, knowledge of the quality characteristics that end users require for the product is sometimes presupposed or misunderstood. The result is often a product that does not achieve the purpose for which it was designed and manufactured. In this context, is it possible to guide the development process methodologically in order to ensure the quality of a product? With reference to Systems Engineering, it is at the stage of Concept in the life cycle of the system that the needs of stakeholders are collected, translated first into stakeholder requirements and then into system requirements. This thesis therefore addresses these steps as a priority. It proposes a methodology to ensure that stakeholder needs are well understood and properly translated into system requirements. The proposal complies with the ISO 15288 (2015) quality standard and incorporates the Lean principles. The thesis also proposes a tool that supports the methodology. The results obtained from several case studies developed at the Tecnológico Nacional de México, Instituto Tecnológico de Toluca (ITTol), Mexico, demonstrate the effectiveness of the proposed methodology. Its use increases the likelihood that the delivered product will meet stakeholder expectations, reduces requirement changes due to misidentification of needs and, therefore, the costs incurred by these changes, and ensures faster delivery of the product to the market.
