Since there is not a one-size-fits-all engineering process or tool, managing customization and extensibility is one key factor in maintaining and nurturing organizations competitive advantage. SystemWeaver incorporates a number of means to achieve extensibility that enables customers to tailor and expand usage of SystemWeaver solutions. Based on a programmable meta model, SystemWeavers data model can easily be extended. In addition, several configurable tools such as reports, grids, mapping views exist that enables working with the meta model and viewing it from different perspectives. 

In addition to build in support for working with tailoring and extending SystemWeaver, an open API gives developers full access to building custom applications integrated with SystemWeaver.

Since all of these features are an inherent part of SystemWeaver and does not require lengthy quality qualifications and upgrades, changes and improvements to SystemWeaver can be managed in an agile, continuous and fast manner.
