A method and system for discovering dependencies, configurations and utilizations among IT resources are disclosed. A discovery team writes a prediscovery script without requesting credentials and sends it to a system administrator (SA) who already has necessary credentials to execute the prediscovery script. Then, the SA reviews the prediscovery script and executes the prediscovery script on a target server. While or after executing the prediscovery script, the target server generates a result of an execution of the prediscovery script and provides the result to an analysis system. The analysis system analyzes and parses the result and generates a user-friendly data (e.g., graph or spreadsheet) that represents the result. Then, the analysis system provides the user-friendly data to the discovery team. The analysis system does not require credentials and does not directly communicate with the target server except receiving the result of the executed prediscovery script from the target server.
