Analysis for Package Enhancement

Analysis for Package Enhancement

Even the best packages are likely to need some form of enhancement for a busi ness. Plug and play packages are rarely available As part of the requirements analysis, some use cases will be identified that are not supported by the package, of that are only partially supported

Packages often come with some recommended method for customization They may seem convoluted at first, but usually they will look something like the process we have been uncovering Firstly you need to define the interactions in some structure similar to the use case definitions we have been using Next, you need to define the interfaces. Then you need to trace the execution of the use case, and link it in to the interface with a series of interactions with pre prepared components Metalwho (perhaps objects, or some other computer representation), and if the components are missing there will be some procedure for defining and adding new components which will follow principles that we will discuss in the design stage
