Technical drawings are detailed diagrams that convey how objects function and are constructed. Engineers, contractors, and electricians use these drawings as guides. A flowchart uses graphic symbols to depict the steps in a process and is also called a flow diagram. The key elements of a flowchart are: terminators that mark the start and end, processes that represent actions, decisions shown as diamonds, and arrow lines that show the flow direction from top to bottom.

2. Technical Drawing
• also known as an engineering drawing, is a
detailed, precise diagram or plan that conveys
information about how an object functions or
is constructed. Engineers, electricians, and
contractors all use these drawings as guides
when constructing or repairing objects and
buildings.

3. Flowchart
• A flowchart is a diagram that uses graphic
symbols to depict the nature and flow of the steps
in a process. Another name for this tool is "flow
diagram."

5. 1. Terminator
A terminator is represented by a small rectangle
with curved corners. A terminator appears at the
start and at the end of a flowchart. The end
terminator appears only once
on a single flowchart.

6. 2. Process
• A process is represented by a rectangle. It refers to an
action in a business process. It must be described
clearly and concisely. A process can be described using
a single verb noun

7. 3. Decision
• A decision is represented by a
diamond. A process that can
answer a decision of "yes" or
"no" requires a decision box.

9. 4. Arrow Lines
• Arrow lines drawn in one direction, preferably from top to
bottom, keep a flowchart clear.
• Avoid arrow lines that loop because this could indicate
redundancy in the business process.
