The most important factor in maintaining Web Engineering Information Systems (WEIS) lifecycle is the reengineering process that in most cases is due to serious problems and hence high maintenance costs; this process must be closely monitored by audit procedures. Once the WEIS was put into production, the maintenance and reengineering considerations started, and the Information System Risk and Quality Check Coefficient (ISRQCC) method was periodically used to audit it. It also established the relationship between the (re)design and the reengineering process. This paper presents the application of the ISRQCC method in the SWI's Web Engineering (WE) project, where the audit operations resulted in a major reengineering process.

This paper proposes the Audit, Control and Monitoring Design Patterns (ACMDP) for building Autonomous and Robust Systems (ARS) such as Mobile Robot Systems (MRS). These patterns are also applicable to other Mission Critical and Complex Systems (MCCS). This paper presents a proposal which will help ARS project managers and engineers design, build and estimate the probability that an ARS will succeed or fail. Furthermore, this proposal offers the possibility to ARS problems with the help of audit, monitoring and controlling components, adjust the project management pathways, and define the problem sources as well as their possible solutions, in order to deliver an ARS or an MRS.
