Later, when Paul is faced with his scheduling conflict, he relaunches FourPlan and is once again faced with Figure 1the initial screen. This time he selects ‘OPEN’ and is shown his old map. The first thing Paul does is select each of the courses he has taken and edit their ‘COMPLETED’ and ‘GRADE’ fields. He then proceeds to resolve his conflict. He does this by selecting the course which conflicts and changes its ‘FIX ON MAP’ field to ‘CHANGE’. This forces the constraint solver to push the course to a future semester and thus pulls a new course over to the current semester. Another option would have been for Paul to click and drag courses around manually to resolve the conflict. When Paul is happy with his map again, he selects ‘SAVE’ and exits the map.
