1. An implementation unit comprises: an input/output module operably coupled to receive application requirements and parameters wherein the input/output module is configured to provide connectivity to another computing entity; and a processing module operable to implement production of application code in an iterative manner using one or more implementation tools and using: an architecture code level design phase to produce code component architecture artifacts of at least a portion of the application code based on one or more of: the application requirements, the parameters, or architecture phase feedback, wherein the architectural code level design phase includes an architectural level design phase loop; a high-level design (HLD) phase to produce code HLD artifacts based on one or more of the code component architecture artifacts, the application requirements, the parameters, or HLD phase feedback, wherein the HLD phase includes an HLD phase loop; a low-level design (LLD) phase to produce code LLD artifacts based on one or more of the code component architecture artifacts, the code HLD artifacts, the application requirements, the parameters, or LLD phase feedback, wherein the LLD phase includes an LLD phase loop; and an application code level development phase to produce code artifacts based on one or more of: the HLD artifacts, the LLD artifacts, the application requirements, the parameters, or code development phase feedback, wherein the application code level development phase includes an application code level development phase loop, and wherein a plurality of the one or more implementation tools is used in one or more of the architectural code level design phase loop, the HLD phase loop, the LLD phase loop and the application code level development phase loop, and wherein a first implementation tool of the one or more implementation tools is used in one iteration of one of the architectural code level design phase, the HLD phase, the LLD phase and the application code level development phase, and a second implementation tool of the one or more implementation tools is used in another iteration of the one of the architectural code level design phase, the HLD phase, the LLD phase and the application code level development phase.
