Bertazo et al - Application Lifecycle Management and process monitoring through an integrated and low-cost solution, mainly based on Open Source Software products
0 likes358 views
The document presents a framework for Application Lifecycle Management (ALM) and performance monitoring using an integrated, low-cost solution based on open-source software. It discusses measuring company performance through a multi-dimensional performance model and tools like Spago4Q, which analyze product, process, and service quality. The approach includes quantitative and qualitative evaluations to support continuous improvement and a structured performance measurement model addressing managerial needs.
