  • The software needs to be tested ensure it functions properly and is stable and reliable.
  • Testing managers-who may not be skilled at communicating with CIOs-can distract attention from the real problems by being overly detailed or focusing on irrelevancies

There are few things worse than being responsible for a software project mired in testing. To those waiting to use the software, the project seems done. But it isn't. The software needs to be tested ensure it functions properly and is stable and reliable. And the project manager's frustration mounts as days turn into weeks, weeks turn into months, and-heaven forbid-months turn into years. (For best practices for running your testing organization, see Testing, 1, 2, 3... February 1, 2006).This process is doubly frustrating for CIOs removed from the  action.  Testing  managers-who  may  not  be  skilled  at communicating with CIOs-can distract attention from the real problems by being overly detailed or focusing on irrelevancies.CIOs must assess the situation for themselves, asking the testing manager the following five questions face-to-face and observing how wide his pupils dilate.

“CiOs must ask the testing manager five questions face-to-face and observe how wide his pupils dilate”

Question #1: Is the software's functionality complete, documented and subject to a formal change process?You're really asking: Are we trying to hit a moving target?You're trying to determine: If the problem is that the software is poorly defined or that the project's scope has changed.Interpreting the response: If the software's functionality is not fully documented or is not clear, testers will have difficulty  determining  whether  it  meets  the  project's goals. When functionality is subject to interpretation, test cases might not reflect what was originally intended. If functionality changes because the organization continually adds,  modifies  or  deletes  functions,  testers  will  have difficulty keeping up. Only changes critical to the integrity of the software should be allowed.

Question #2: Is development complete?You're really asking: Are the testers essentially starting over with each new release because there are so many changes?You're trying to determine: If the software has been released for testing prematurely, or if changes are uncontrolled.Interpreting the response: Software released prematurely will differ markedly from the previous release. With all the changes, testing performed on a previous release might no longer be relevant to the new one. If testing of one release is not completed before the next one arrives, there will be no comprehensive understanding of release defects. After each release, the software will change due to user feedback. But problems will occur if developers and testersdo not agree

You're trying to determine: If the organization is making good decisions about where to apply its assets. Interpreting the response: Defects vary in severity. For example, a defect in the cosmetics of a screen form is less severe than a defect that stops the software cold. A defect that impacts many users is more severe than one that impacts few users. The order in which the development team resolves defects should be in line with their severity.

Trouble occurs when the development and test teams do not communicate about which defects to remedy and in which order. To ensure improvement of the software and for the test phase to move toward completion, the development and test teams must collaborate.A related symptom to check: The number of highest severity defects does not diminish over time; friction exists between development and test organizations.
