Abstract
This article presents proposals for definition of requirements related to defense systems projects, considering upcoming developments of cruise missiles as an application. Based on the Tomahawk missile history, it recommends interactions between the project’s sponsoring organization and development engineers in a process of adjustments and tailoring between the user’s initial expectations, the technology readiness level (TRL), and national industrial skills. This task may provide in-depth analyzes and solutions to technically advise authorities in the decision-making process, involving engineering projects related to the national defense strategy. Also, a new type of requirement, the zero requirements, is created and characterized by an immutable demand from the main stakeholder, which decisively affects the product’s final characteristics. Finally, the article proposes improvements in the requirements writing by adding new information fields to understand the user’s initial goals better and provide an initial resource/cost/time-consuming estimation.
