Mark, Pam, and Rick all work in the IT department for a large manufacturing company. Mark supports the accounting department, Pam supports the purchasing department, and Rick supports the quality control department. Mark has started working on a new software application to upgrade the financial software to something that runs on a different operating system than the previous version. Pam is in the middle of a project that involves delivering better custom reports, based on purchasing data. Rick has been asked to develop a new custom system for the quality assurance department that will help the company in receiving ISO 9000 certification. Problems began to surface during the implementation of the new accounting software. It turned out that the new accounting software was not compatible with the old purchasing software and required new information to be tracked by the purchasing agents. Pam was nearly done with her new reports when she found out that they would need to be changed, and the work so far has been wasted. Rick was upset because they would have to stop their work on the ISO 9000 certification until the issues were resolved. Explain how the use of the systems approach could have helped avoid many or even all of these problems.
