How to Draw a Process Flow Chart
- 1). Write out the steps in the process you want to illustrate. For example, in a process of a calculator software application, the steps would be: "User presses a number button. User presses a calculate button. User presses another number. User presses the 'equal' button. Calculator displays answer."
- 2). Write the title that describes your process at the top of the page on a new sheet of paper. Skip down approximately 1 inch below the title in the upper left-hand corner of the page and draw an elongated circle approximately 1 to 1.5 inches wide and no more than 3/4-inch tall. Write "Start" in the middle of the elongated circle.
- 3). Draw a downward arrow and make a rectangle to show an action. Write inside the rectangle, "Press a Number Button." Draw another downward arrow.
- 4). Place a diamond shape on its side so the pointy left side is on the top and it stretches out lengthwise from left to right. Inside the diamond write, "Choose Addition?" with an arrow down and an arrow to the right of the diamond. Write above the arrow to the right the word "No."
- 5). Write the word "Yes" along the downward arrow and then a rectangle. Inside the rectangle, write "Press a Number Button." Draw another downward directional arrow leading to another rectangle. Inside that rectangle, write "Perform Calculation."
- 6). Draw another arrow downward to another rectangle that says "Display Answer" inside of it, completing the addition process. Go back up to the "No" arrow line to the right of the diamond and draw another diamond shape the same way as the first. Write inside it, "Pick a Different Operator?"
- 7). Draw directional arrows in a straight line away from the remaining three points of the diamond. Label the top arrow "Subtraction," the arrow to the right "Multiplication" and the bottom one "Division." Continue the top arrow to the right at a 90-degree angle, down another 90-degree angle and to the left yet another 90-degree angle to reach the "Perform Calculation" box. Draw the other two lines to reach the "Perform Calculation" box.
