Spiral Model Tutorial

Although the diagram may appear straightforward, creating it in PowerPoint can be quite challenging. However, this tutorial will guide you through the process of crafting the diagram in a straightforward and efficient manner. By following these steps, you will be able to produce a professional-looking diagram that effectively conveys your message.

Spiral life cycle model or Incremental model:


The Spiral or Incremental Model is a widely used approach in software development. This model involves designing, implementing, and testing the product incrementally until it is completed. As it follows the philosophy of iterative development, it is also known as the prototyping model.

Although this model is primarily designed for software development, its principles can be applied to various management and strategic presentations. Therefore, we have provided step-by-step instructions on how to create this valuable model.

Without further ado, let us begin...

1. Draw a set of semicircular arcs

One of the easiest ways to create a spiral diagram is by drawing and merging semi-circular arcs. Here's how you can do it:

First, go to the Auto Shapes menu and select the Arc tool.

Then, extend the yellow handles until you create a perfect semi-circular shape. To test the shape, draw a flat line and place the arc on top of it.

It's important to get the arc in a proper semi-circular shape for the accuracy of the diagram. Once you have the shape right, make seven copies of the shape apart from the original one.

Next, select an arc and go to the Format ribbon. Enter the height and width as 0.75 each. This will create a semi-circular arc with a diameter of 0.75pt.

Repeat this process for arcs with diameters of 1.5, 2.25, 3.0, 3.75, 4.5, 5.25, and 6.0pt. Once you have all the arcs, select them all and go to Arrange -> Align -> Align Centre and Align Middle. This will give you a perfectly aligned spiral diagram.

2. Group alternative arcs and flip them vertically

The next step is to select alternative arcs and color them red using ‘Shape Outline Color’ option.

 Now, group the red and black arcs separately. Select the ‘black arcs’ group -> Arrange -> Rotate -> Flip Vertical. You will get the following result:

 Select both the groups -> Arrange -> Align -> Align Right. Change the Shape Outline Weight to 3 pts. Your spiral chart is ready:

Application of the diagram:

You can add an arrow head to the last semi circle of the Spiral Model and place it inside a wheel diagram to indicate spiraling process as follows:

Or you can use the diagram just created as part of segmented wheel like this:

You can add an arrow tip at the end of each semi-circle and use the spiral model in a four-quadrant chart as follows:
