Q1) What is a TOE (Task,Object,Event)chart? Describe how it is created and used in the planning phase of an application.
Answer: A TOE (Task,Object,Event)chart is used to record the application's tasks,objects,and events,which are identified in the first three steps of the planning phase.The first step in creating the TOE chart is identifying the application's tasks.The tasks are then listed in the first column of the chart under the label "Tasks." After completing the Task column of the TOE chart,you then assign each task to an object in the user interface.Each object is listed in the second column,labeled "Object," for each corresponding task.After defining the application's tasks and assigning the tasks to objects in the interface,you then determine which event (if any)must occur for an object to carry out its assigned task.The events are listed in the third column,labeled "Event," for each corresponding task and object.
Q2) Labels that identify other controls (such as text boxes)should be right-aligned according to Windows standards.
