Organizations must maintain best efforts to both make sure purchased software is up to date and make sure their own software and programming is as bug-free as possible by employing software metrics and rigorous software testing. Ongoing use of metrics allows the information systems department and end users to jointly measure the performance of the system and identify problems as they occur. Examples of software metrics include the number of transactions that can be processed in a specified unit of time, online response time, the number of payroll checks printed per hour, and the number of known bugs per hundred lines of program code. For metrics to be successful, they must be carefully designed, formal, objective, and used consistently. Early, regular, and thorough testing will contribute significantly to system quality. the software should be tested carefully before it publish to the market by a small group of people carefully selected based on the skills needed for the particular objectives being tested.
