A software developer is a person or organization concerned with facets of the software development process wider than design and coding, a somewhat broader scope of computer programming or a specialty of project managing including some aspects of software product management. This person may contribute to the overview of the project on the application level rather than component level or individual programming tasks. Software developers are often still guided by lead programmers but also encompass the class of freelance software developers.
With time and a little luck, differences between system design, software development and programming are more apparent. Already in the current market place there can be found segregation between programmers and developers, being that one who actually implements is not the same as the one who designs the class structure or hierarchy. Even more so that developers become systems architects, those who design the multi-leveled architecture or component interactions of a large software system. (see also Debate over who is a software engineer)
A 'programmer' is responsible for writing code, but a 'developer' could be involved in wider aspects of the software development process such as:
Participation in software product definition, including Business case or Gap analysis
Requirements analysis
Development and refinement of throw-away simulations or prototypes to confirm requirements
Feasibility and Cost-benefit analysis, including the choice of application architecture and framework, leading to the budget and schedule for the project
