Methods and systems are disclosed for defining deployment data that identify a manner in which to divide a software package of source code deliverables into smaller discrete software package. A triggering event occurring in response to a modification of one or more source code deliverables causes a set of source code deliverables to be identified. One or more particular metadata identifiers associated with the modified one or more source code deliverables may be used to define a group of source code deliverables. The group of source code deliverables includes a subset of the set of source code deliverables that may also be associated with the one or more particular metadata identifiers. One or more packaging rules may facilitate defining deployment data identifying package transmissions for the group of source code deliverables. The deployment data may then be output to one or more devices.
