If a module must perform multiple tasks, ____.

User documentation ____.

In a top-down design, the overall objectives of a system are broken down into ____ in a process called partitioning.

-As the accompanying figure illustrates, the ____ changeover method allows the new system to be implemented in stages, or modules.

Restricting the implementation to a pilot site increases the risk of system failure, compared with a direct cutover method, and operating both systems for only the pilot site is more expensive than a parallel operation for the entire company.

When the output from a validation program becomes input to a master file update program, testing the two programs independently guarantees that the data passed between them is correct.

Which of the following is not specified by the detailed procedures in a test plan?

Although programmers perform the actual coding, IT managers usually assign systems analysts to work with them as part of a team.

In a technique called ____ testing, the programmer simulates each program outcome or result and displays a message to indicate whether or not the program executed successfully.
