Business activity tracking can improve requirement analysis for maintaining legacy applications
Legacy applications can benefit from big data approaches without the need to replace the legacy architecture with new technologies. Instead the big data can augment the application by collecting higher volume, variety, and velocity data about the user’s activity using the application. Analysis of this data can inform decision makers where there may be problems with the work-products. Correspondingly, it can provide requirements analysts with information about where improvements are needed or with more complete library of edge cases to consider for new designs.
