Medicare's hospital outpatient prospective payment system (HOPPS) was initially developed in response to the rapid rise in Medicare's outpatient expenses between 1980 and 1991. The Balanced Budget Act of 1997 mandated HOPPS, with an implementation date of August 1, 2000. Unlike the Medicare Physician Fee Schedule, the Centers for Medicare and Medicaid Services (CMS) used hospital charge data to...

This paper categorizes some aspects of software process evolution and customization, and describes how they are handled in the EPOS PM system. Comparisons are made with other PM systems. A process model in EPOS consists of a Schema of classes and meta-classes, and its model entities and relationships. There is an underlying software engineering database, EPOSDB, o ering uniform versioning of al...

Evolution of service-oriented systems is quite a new research area, which becomes more and more important as engineering challenges move from enabling service-orientation onto the maintenance and evolution of already developed service-oriented systems. However, the development of suitable evolution processes and methodologies is still an open research problem. The evolution process presented in...

The ability to handle changes is a characteristic feature of successful software projects. The problem addressed in this paper is what should be done in project planning and iterative replanning so that the project can react effectively to changes. Thus the work presents research results in software engineering, as well as transfer of methods in knowledge engineering to software engineering, ap...

Knowledge workers tailor collaborative business processes to local conditions. They own (i.e., create and maintain) representations of these local processes (such as checklists) to guide the work. Our goal is to design tools to support the ownership of collaborative local processes by enabling workers to flexibly adapt process representations to work situations. This paper focuses on how worker...

The primary goal of a process evolution tool is to Evolver generates a graph reflecting only the consistency guarantee that the pre-existing objectbase is consistent implications among rules in the new process model, and with respect to the newly installed process. We had compares it to the consistency rule graph representing the previously proposed an approach that rejected changes to existing...

Modeling business processes is a complex and time-consuming task, which can be simplified by allowing process instances to be structurally adapted at runtime, based on context (e.g., by adding or deleting activities). The process model then no longer needs to include a handling procedure for every exception that can occur. Instead, it only needs to include the assumptions under which a successf...

Rapid evolution of interspecific interactions (during a timespan of about 100 years) has the potential to be an important influence on the ecological dynamics of communities. However, despite the growing number of examples, rapid evolution is still not a standard working hypothesis for many ecological studies on the dynamics of population structure or the organization of communities. Analysis o...
