A method for providing a safe operation of a technical system, S, comprising a set of system components, said method comprising: (a) providing a safety analysis model (CFT c, CFT d, CFT u) of said technical system, S, matured by knowledge about former implementations of the respective system components (c,d,u) in different contexts; (b) whereby system components' (c,d,u) dependencies are modelled by connecting inports with outports of the respective system components (c,d,u) and/or by connecting outports with inports of the respective system components (c,d,u); (c) whereby the inports and/or outports of each system component (c,d,u) are associated with input failure modes, IFM, and/or output failure modes, OFM, of the respective system component (c,d,u); and (d) automatically uncovering inconsistencies (A,B,C,D) caused by at least one new system component (c) to be integrated in connection with at least another downstream system component (d) or upstream system component (u) of an existing technical system, whereby the input failure modes, IFM, and/or output failure modes, OFM, of the system component (c) to be integrated carries the knowledge from another implementation into a new context; (e) wherein for the system component (c) to be integrated into the existing technical system, the failure modes which require integration and unconnected failure modes of the system component (c) to be integrated are identified using a previously defined set forward for the system component (c) to be integrated which identifies unconnected failure modes of the system component (c) to be integrated, whereby existing knowledge of the system component (c) to be integrated is transferred into a new technical system where the system component (c) to be integrated is reused; and (f) wherein for the system component (c) to be integrated into the existing technical system, unconnected failure modes of the system component (c) to be integrated are identified using a previously defined set backward for the system component (c) to be integrated which contains unconnected failure modes of the existing system components where the system component (c) is to be integrated, whereby existing knowledge of the existing technical system is transferred back to the reused system component (c) of the technical system, whereby existing instances of the reused system component (c) in other systems or implementations are reviewed. (a) providing a safety analysis model (CFT c, CFT d, CFT u) of said technical system, S, matured by knowledge about former implementations of the respective system components (c,d,u) in different contexts; (b) whereby system components' (c,d,u) dependencies are modelled by connecting inports with outports of the respective system components (c,d,u) and/or by connecting outports with inports of the respective system components (c,d,u); (c) whereby the inports and/or outports of each system component (c,d,u) are associated with input failure modes, IFM, and/or output failure modes, OFM, of the respective system component (c,d,u); and (d) automatically uncovering inconsistencies (A,B,C,D) caused by at least one new system component (c) to be integrated in connection with at least another downstream system component (d) or upstream system component (u) of an existing technical system, whereby the input failure modes, IFM, and/or output failure modes, OFM, of the system component (c) to be integrated carries the knowledge from another implementation into a new context; (e) wherein for the system component (c) to be integrated into the existing technical system, the failure modes which require integration and unconnected failure modes of the system component (c) to be integrated are identified using a previously defined set forward for the system component (c) to be integrated which identifies unconnected failure modes of the system component (c) to be integrated, whereby existing knowledge of the system component (c) to be integrated is transferred into a new technical system where the system component (c) to be integrated is reused; and (f) wherein for the system component (c) to be integrated into the existing technical system, unconnected failure modes of the system component (c) to be integrated are identified using a previously defined set backward for the system component (c) to be integrated which contains unconnected failure modes of the existing system components where the system component (c) is to be integrated,
