Air Compression Functional Flow Block Diagram
Step-wise example of how to create a useful Functional Flow Block Diagram. read more.
Defining Functions
When presented with an operational task to be accomplished, End Users often lean toward using tools that they've used before, leading to certain biases in the description (and specification) of the designs. Yielding to that temptation can have deleterious effects on development. System Engineering practices use the abstract concept of a "function" to focus on mitigating such biases. read more.
Four-bar Linkage Failure Functional Discovery Analysis
Functional techniques are usually discussed in the context of a requirements development process. They can, however, support other processes. A concrete example is described here, based on events in the real world. read more.
Function Fun
Five new pages were released today, all pertaining to very basic developmental operations in the Function Domain: Defining Functions is a “foundational page” addressing how functions are described; Functional Flow Block Diagrams (FFBD) describes one of many options for depicting and documenting functions and the relationships between them; Air Compressor Functional Flow Block Diagram Development is an... read more
Functional Flow Block Diagrams
Many techniques and formats have been developed (and used) to express functionality in systems. An extension of one legacy method is introduced here. Unlike many other approaches, the method requires neither any particular supporting software or sophisticated syntax. read more.
Machine Controller Test Anomaly
Functional techniques are usually discussed in the context of a requirements development process. They can, however, support other processes. The concrete example described here was based on events in which the presence of any perceptible functionality at all was in doubt. read more.
Measuring Performance
Two different types of Performance Measures are defined and described. Their abstract characteristics permit the quantification of how well Functions are performed by the developed system. read more.
