This disclosure relates generally to a human machine interface (HMI) application, and more particularly to method and system for developing and delivering the HMI application from a host service delivery platform (HSDP) to a target platform. In one embodiment, a method for delivering an update on the HMI application from the HSDP to the target platform is disclosed. The method may include determining a need for updating the HMI application on the target platform, which implements a previous version of the HMI application. Based on the need, the method may further include, generating a package based on a comparison between a database emulating a current version of the HMI application and a database emulating the previous version of the HMI application, and delivering the package for updating the HMI application on the target platform. The database may be implemented in a database schema.
