Workflow monitoring and analysis concerns aim at identifying potential improvements of workflow applications. This paper presents an approach to specify and implement monitoring and analysis concerns on workflow applications raising the level of abstraction for workflow analysts. First, the specification of monitoring and analysis concerns is declared in a technology-independent way with a domain-specific language named MonitA. MonitA makes extensive use of the data available in the workflow application and its constituents to enhance the monitoring and analysis specifications. Second, we defined and implemented a strategy to assist developers to enhance a given workflow technology to support the generation of the monitoring and analysis code and its composition with the workflow application. This instrumentation-based approach enables the monitoring and analysis of workflow applications during their operational execution. We illustrate the flexibility of our approach by targeting different workflow platforms and different workflow applications.

In workflow management systems, analysis concerns related to monitoring, measurement, and control aim at identifying potential improvements of workflow applications. However, the specification of analysis concerns is done using a specific workflow language and engine, producing entangled code which is detrimental to their maintainability. The purpose of this paper is twofold. First, it presents briefly a domain-specific language to specify analysis concerns, independently of any workflow technology and in a modularized way. Second, it shows a strategy to assist developers to enhance a given workflow technology to support the automated implementation of analysis concerns into its workflow applications. Thus, given a workflow application and its analysis concerns, they are automatically integrated producing an enhanced executable workflow application.

As current software systems evolve continuously, both the application and its user interface (UI) have to be adapted. However, UI code is often scattered through and entangled with the application code. In large and complex UIs, this tangling renders the implementation complex and hard to maintain. The Deuce framework (Declarative User Interface Concerns Extrication) intends to reduce the complexity of UI implementations by applying separation of concerns on three UI concerns: presentation logic, business and data logic, and connection logic. It does so by using a declarative meta-language (SOUL) on top of an object oriented language (Smalltalk) such that an adequate language is provided to describe the entire structure and behavior of the UI, as well as linking it with the application.
