It is very difficult to refuse to already established processes and spend again understandable amount of resources on adapting processes which may not be able to improve or at least provide the same level of work in the new system, as in the old. The last point seems the simplest to implement, but it is at first glance. First, you need to teach Manager for applications using both systems, such as HP Service desk and IBM Rational ClearQuest. Second, because in the workplace will be installed two systems, then of course for each system requires separate licenses. Third, very would be difficult to arrange proper registration process applications, ie initially it will be difficult to correctly identify the application and register it in the right system. Well, if you suddenly need to be translated on request processing for some reason the developers of the department in the service department, then the manager will have to manually transfer information about the application. Fourth, even if it will generate flawless process identifying the problem, which further ensures error-free determination of the recipient's errors, to obtain information about the status of the application in error manager will still have to conduct its own database and numbering in he will be celebrating all the incoming requests and place them in different systems. As you can see, it is difficult to determine the correct path of the situation. Often try to make one of the first two paragraphs, with takes time, money and nerves when attempting to force one system all the necessary aspects.
