I like to think of sustainability in terms of systems engineering and system architecture, where you assess the risk involved and plan for the life cycle support of the system, whether a business system, IT, or a fighter jet. Will their be training available 3 yrs from now? Will parts and tech support suppliers be around? Is their a new gov mandate coming that will negatively change our support posture in 3-5 yrs? etc., etc. These are design considerations for a system, and if well thought out and done properly, the system is sustainable well into the operations and maintenance phase. The opposite would be a non-sustainable system where these factors are overlooked and you’re stuck with a fighter jet with no source of supply for a $20 part (usually = grounded jet)
