Jackson's aim was to make COBOL batch file processing programs easier to modify and maintain, but the method can be used to design programs for any programming language that has structured control constructs- sequence, iteration, and selection ("if/then/else"). In a 2001 conference talk, he provided a retrospective analysis of the original driving forces behind the method, and related it to subsequent software engineering developments. He documented the system in his 1975 book Principles of Program Design. Jackson originally developed JSP in the 1970s. These structures are diagrammed as (in effect) a visual representation of a regular expression. JSP describes structures (of both data and programs) using three basic structures – sequence, iteration, and selection (or alternatives). The technique of JSP is to analyze the data structures of the files that a program must read as input and produce as output, and then produce a program design based on those data structures, so that the program control structure handles those data structures in a natural and intuitive way. Jackson and described in his 1975 book Principles of Program Design. Jackson structured programming ( JSP) is a method for structured programming developed by British software consultant Michael A.
