Coding is not a synonym for software development. Software development requires writing / comprehending specifications, analyzing the task at hand thoroughly, designing a solution that is computationally feasible and that interfaces properly with any current systems, implementing that solution using the available / best programming languages, libraries, and platforms, performing unit tests while working on the implementation, and writing documentation for the application or feature (not to mention, writing comments all along while writing the implementation). "Coding" is merely implementing a well-conceived design using one or more programming languages, libraries, and/or platforms; "coding" is the easy part.
