Answer to Question 1

D

Answer to Question 2

Nothing ever goes according to plan; the larger the project and the longer the development interval, the more things will violate the plan. Four critical factors need to be considered:
1. Coordination
2. Diseconomies of scale
3. Configuration control
4. Unexpected events
CoordinationDevelop ment projects, especially large-scale projects, are usually organized into a variety of development groups that work independently. Coordinating the work of these independent groups can be difficult, particularly if the groups reside in different geographic locations or different countries. An accurate and complete WBS facilitates coordination, but no project ever proceeds exactly in accordance with the WBS. Delays occur, and unknown or unexpected dependencies develop among tasks.
Diseconomies of scaleThe number of possible interactions among team members rises exponentially with the number of team members. Ultimately, no matter how well managed a project is, diseconomies of scale will set in.
Configuration controlAs the project proceeds, controlling the configuration of the work product becomes difficult. The development team produces an initial statement of requirements. Meetings with users produce an adjusted set of requirements. An event could occur necessitating a change to requirements. Similar problems occur with designs, program code, database data, and other system components. The term configuration control refers to a set of management policies, practices, and tools that developers use to maintain control over the project's resources. Such resources include documents, schedules, designs, program code, test suites, and any other shared resource needed to complete the project.
Unexpected eventsThe last major challenge to large-scale project management is unexpected events. The larger and longer the project, the greater the chance of disruption due to an unanticipated event.
