Prerequisites Worksheet Answers
1. For the Volume Controls guide, you’ll need to import the Front Panel Assembly and Battery prerequisite guides.
2. The Lightning Connector and Logic Board guides are both tied for having the most prerequisites with four guides
each.
3. The Front Panel Assembly guide is a prerequisite for all other guides.
4. The Logic Board guide requires the Front Panel Assembly, Battery, Logic Board Assembly, and Rear Facing
Camera prerequisite guides.
5. The prerequisite guides are listed as follows: Front Panel Assembly, Earpiece Speaker, Battery, Logic Board
Assembly, Lightning Connector & Speaker Assembly, Rear Facing Camera.
6. You should reassemble the Front-Facing Camera & Sensor Cable and the Earpiece, since you don’t need to
remove these to replace the home button.
7. A guide is prerequisite-only if it is only used in the process of replacing another component. For instance, you might
take something out of your device that isn't a single component, but rather a cluster of smaller components, such as
a display assembly or motherboard assembly. Removing these assemblies is necessary to replace the display or
motherboard.
8. A repair guide shows users how to fix something that is broken or damaged, but not how to replace them. For
example, a ripped garment doesn’t necessarily need to be replaced since it can be fixed with some simple stitching.
Replacement guides differ in that they show how to fix something by replacing specific components (RAM, LCD, etc)
that have failed, but not how to repair them.
9. Prerequisites simply add the steps from existing guides to the beginning of your new guide, so that they show up
before any new steps, breaking your guides up to be specific to one component.
10. Answers will vary, just make sure that students understand the concept of using prerequisites to save time.
