15. A computer program product in a non-transitory computer readable storage medium for use in a computing entity, the computer program product holding computer program instructions which, when executed, generate a software system pipeline comprising a set of elements, the computer program instructions comprising: code to store dependency data for one or more elements, the dependency data for at least a particular element having been derived from a data model generated as a result of executing at least one other pipeline in which the particular element was included; code to identify a first element; code to associate a second element to the first element to form a portion of the software system pipeline, wherein the particular element is one of the first and second elements; code to retrieve dependency data for at least one of the first and second elements, at least some of the retrieved dependency data being dependency data that was derived from the data model; and code to automatically generate descriptor data for the software system pipeline based on the retrieved dependency data.
