Process-centered software engineering environments (PSEEs) facilitate controlling complicated software processes. Traditional PSEEs are generally centrally controlled, which may result in the following drawbacks: (1) the server may become a bottleneck and (2) when the server is down, processes need to be suspended. To overcome the drawbacks, we developed a decentralized process engine ADPE (agent-based decentralized process engine). ADPE can be embedded in any PSEE to decentralize the PSEE. This paper presents ADPE.

Process-centered software engineering environments (PSEEs) facilitate controlling software processes. Many issues related to PSEEs such as process evolution support have been addressed. We identify an unsolved issue, which is preventing information leakage when the process is being enacted. We developed a model called PsACL for the prevention. This paper proposes PsACL, which offers the following features: (a) controlling both read and write access of software products, (b) preventing indirect information leakage, (c) managing role associations, (d) managing role hierarchies, (e) enforcing static and simple dynamic separation-of-duty constraints, (f) allowing declassification of products, and (g) allowing access control information exchange among software processes.

This paper presents a model called PECM (process environment coordination model) to coordinate heterogeneous PSEEs. A PSEE coordinated by PECM is associated with a standard-interfaced PECM coordinator, which provides primitive coordination functions. PECM uses shared product status to coordinate PSEEs. It is expected to offer several features. First, multiple PSEEs can be used in the same project. Second, PECM manages products and product relationships across PSEEs. Third, PECM coordinator is standard- interfaced, which is easy to use.
