nformational website, which will ultimately evolve into an extranet through which RPS will share nformation and link its process closely with its clients and suppliers. After basic processes are automated and the extranet website is in place, the system will enable clients to add patient information and place orders through the web. The system should streamline processes for both RPS and its clients. It should also provide useful query and patient management capabilities to distinguish RPS's services from those of its competitors, possibly including drug nteraction and overdose warnings, automated validation of prescriptions with insurance reimbursement policies, and drug and patient cost data and summaries. 1. One approach to system development that RPS might take is to start one large project that uses a waterfall model to the SDLC to thoroughly plan the project, analyze all requirements in detail, design every component, and then implement the entire system, with all phases completed sequentially. What are some of the risks of taking this approach? What planning and management difficulties would this approach entail? 2. Another approach to system development might be to start with the first required component and get it working. Later, other projects could be undertaken to work on the other identified capabilities. What are some of the risks of taking this approach? What planning and management difficulties would this approach entail? 3. A third approach to system development might be to define one large project that will use an iterative approach to the SDLC. Briefly describe what you would include in each iteration. Describe how incremental development might apply to his project. How would an iterative approach decrease project risks compared with the first approach? How might it decrease risks compared with the second approach? What are some risks the iterative approach might add to the project
