Example of a Structured Chart.[1]

A Structure Chart (SC) in software engineering and organizational theory, is a chart which shows the breakdown of a system to its lowest manageable levels.[2] They are used in structured programming to arrange program modules into a tree. Each module is represented by a box, which contains the module's name. The tree structure visualizes the relationships between modules.[3]

Structure chart construction

A process flow diagram describing the construction of a structure chart by a so called Subject Matter Experts (SME).[2]

According to Wolber (2009), "a structure chart can be developed starting with the creating of a structure, which places the root of an upside-down tree which forms the structure chart. The next step is to conceptualize the main sub-tasks that must be performed by the program to solve the problem. Next, the programmer focuses on each sub-task individually, and conceptualizes how each can be broken down into even smaller tasks. Eventually, the program is broken down to a point where the leaves of the tree represent simple methods that can be coded with just a few program statements".[4]

In practice, see figure, first it is checked if a Structure Chart has been developed already. If so an expert needs to review it to ensure it represents the current structure and if not, updates the chart where needed.[2]
