Claim:
1. A computer system for model driven development, the computer system comprising: one or more computer processors; one or more computer-readable storage media; program instructions stored on the computer-readable storage media for execution by at least one of the one or more processors, the program instructions comprising: instructions to analyze program code to determine execution sequence of statements of the program code, the program code being generated by performing a first transformation to a model, the model including an abstract description of a business implemented by the program code; instructions to group at least a part of the statements of the program code into functional blocks; instructions to create a visual representation of the program code based on the execution sequence and the functional blocks, for display; instructions to determine a code snippet to be preserved in the program code, in response to receiving an annotation input of the visual representation, the code snippet to be preserved in new program code generated by instructions to perform a second transformation to the model, the second transformation being executed after the first transformation; instructions to generate, by the computer, metadata of the code snippet; and instructions to update, by the computer, a transformation policy of the model, wherein the transformation policy is based on the metadata to control the second transformation of the model, and a user selection of the visual representation of the program code based on the execution sequence and the functional blocks.
