Divide the system into at least two separate components

When Wayne Johansen turned 16, his dad bought him a new Garmin handheld GPS system. His family had always enjoyed camping and hiking, and Wayne was usually the one who monitored their hikes with his dad’s GPS system. He always liked to carry the GPS to monitor the routes, distances, and altitudes of their hikes. More recently, though, he had found a new hobby using his GPS system: geocaching.

Geocaching is a high-tech version of the treasure hunts that most of us did when we were kids. Participants search for geocaches or caches that are small, hidden, waterproof containers that typically contain a logbook and perhaps a small item. When found, the participant sometimes gets instructions for the next move—to either enter information into a logbook or to look for the next cache.

As Wayne became more involved with his hobby, he discovered that there are many different kinds of activities for geocaching enthusiasts. The simplest ones are those that involve caches found by using GPS coordinates, although even some of these tasks can be difficult if the caches are well hidden. Some of the activities involve multipoint drops where there is a set of clues in multiple locations that must be followed to arrive at the final cache point. Some activities involve puzzles that must be solved to determine the coordinates of the final cache.

Before long, Wayne wanted to make his own caches and post them for people to find. He discovered that there were several Web sites with access to geocaching information, caches, and memberships. He joined one of the geocaching Web sites and used it to log his finds. But he decided he would like to create his own system for tracking all the information he had about his caches. Conveniently, Wayne’s older brother

Nick, a college student majoring in information systems, was looking for a semester project for one of his programming classes. The two of them decided to develop a system to help Wayne keep track of all his geocaching activities.

Day 1: Plan the Project

Based on the scope and vision you described in the System Vision Document, divide the project into at least two separate subsystems that can be done in separate iterations. For example, perhaps a first version can run on a laptop, with a second version that includes mobile components for a smartphone. These activities are related to Core Process 2: Plan and monitor the project—what to do, how to do it, and who does it.

Divide the system into at least two separate components or subsystems, which can be supported with two iterations. Briefly describe each.
