Structure chart
A Structure Chart (SC) in software
engineering and organizational theory is
a chart, which shows the breakdown of
the configuration system to the lowest
manageable levels.[2]
This chart is used in structured
programming to arrange the program
modules in a tree structure. Each
module is represented by a box, which
contains the module's name. The tree
structure visualizes the relationships
between the modules.[3]
[1]
Example of a Structured Chart.
Overview
A structure chart is a top-down modular design
tool, constructed of squares representing the
different modules in the system, and lines that
connect them. The lines represent the connection
and or ownership between activities and
subactivities as they are used in organization
charts.[4]
In structured analysis structure charts, according to
Wolber (2009), "are used to specify the high-level
design, or architecture, of a computer program. As
a design tool, they aid the programmer in dividing
and conquering a large software problem, that is,
recursively breaking a problem down into parts

A structure chart depicts[2]
• the size and complexity of the system, and
• number of readily identifiable functions and modules within each function and
• whether each identifiable function is a manageable entity or should be broken down into smaller components.](https://image.slidesharecdn.com/structurechart-110419224319-phpapp01/85/Structure-chart-1-320.jpg)

A structure chart is also used to diagram associated elements that comprise a run stream or thread. It is often
developed as a hierarchical diagram, but other representations are allowable. The representation must describe the
breakdown of the configuration system into subsystems and the lowest manageable level. An accurate and complete
structure chart is the key to the determination of the configuration items, and a visual representation of the
configuration system and the internal interfaces among its CIs. During the configuration control process, the
structure chart is used to identify CIs and their associated artifacts that a proposed change may impact.[2]
Structure chart construction
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".[5]

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]

Structure chart
A structure chart is a top-down diagram that shows the breakdown of a system into manageable sub-modules. It represents each module as a box with lines connecting them to show relationships. Structure charts are used in software engineering to plan program structure and divide a problem into smaller tasks. They provide a hierarchical visualization of how a program or system is decomposed.
