Scenario
The Video DVD Delivery Project involves developing a Web-based application and support structure to provide customers with video DVDs on a monthly rental basis. For example, a customer might pay a monthly fee and then be able to order several video DVDs over the Internet, receive the DVDs via express mail, return those DVDs via express mail, and keep receiving additional DVDs. Several companies already provide this type of service for movie rentals. Market research and corporate values suggested your company focus on educational and sports-related video DVDs only, and DVDs would be available for all types of platforms, including popular gaming systems, computers, and learning systems used in pre-schools and elementary schools. You also plan to serve an international market, providing information and products in several different languages. This system must be very user-friendly, providing customers the ability to search for specific DVDs by platform, age and gender appropriateness, customer reviews, sport (for sports-related DVDs), language, and so on. Registered customers must be able to order the videos, track delivery and return of videos, pay online or via other payment methods (including automatic credit card or bank payments, check, school payment systems, etc.), and provide reviews of DVDs. The system must also be able to track referrals to the site from corporate partners and customer referrals, display advertisements, and track customer usage patterns.

Assumptions:
1. Assume that you have been assigned to work on the Video DVD Delivery Project described above. You are part of a team to define skill requirements for the project manager for this project. You would actually like to get the project manager position.
2. Assume this project will take twelve months to complete and cost about $500,000, and monthly operating costs would be about $50,000 per month for year one and $60,000 per month for years two and three. Estimated benefits are about $1 million the first year after implementation and $2 million the following two years.

得到以上资料之后我对这项目的理解是一个商业活，而非一个软件的开发！
要写这个项目的WBS，我有迷惑了！到底是属于输出服务了，还是输出产品了？改按这么样一个方式分解了?按职能分解还是按项目阶段分解！
望高手赐教！
最后好能写出第二级分解节点！
