The document outlines the seven stages of a software development process: analysis, design, implementation, testing, documentation, evaluation, and maintenance. It then discusses the analysis stage in more detail, noting that analysts read and understand the problem, interview clients for clarity, and develop a software specification as a statement of the problem and basis for legal agreement between the analyst and client. Finally, it introduces questioning for requirements of a program to calculate averages, asking about inputs like number of numbers in the set, data types, and output display specifics.
