The mode, defining the specific type of functional behaviour that a system exhibits during its operation, is an important architectural level concept, which has a significant impact on system design, verification and dependability. The notions of modes and mode changes are widely used by the industrial engineers to structure reasoning about different conditions of system functioning. Even though there has been some work on developing modal systems, we still lack a general understanding of how to architect, verify and ensure depend-ability of such systems. In our work we rely on formal model-ling and verification to study intricate relationships between fault tolerance, operation modes and architectural design.
