This chapter discussed the first two core processes of a system development project and the activities within these core processes. Obviously, for a normal project, these first two core processes are done at the beginning. When the project manager is still learning about the needs of business and trying to develop a vision of the solution. However, in this case, you have already gathered a lot of information about On the Spot from the previous chapters. Use this information to develop some project management planning documents. In Chapter $2,$ you developed a list of use cases. In chapter $8,$ you have identified four required subsystems in total solution. Chapter $6$ provided a good review of the essential system capabilities. Using the discussions of On the Spot from these chapters and the items you have produced from your previous work, produce these items: $1)$ Create a system vision document. $2)$ Review all the use cases that you have identified in chapter $2$ and then enhance the list to achieve a complete solution based on the narratives that you have read in previous chapters. In chapter $5,$ you learned how to do a CRUD analysis. A CRUD analysis of this cases indicates that it might be necessary to add a new subsystem called "Administration." Assign use cases to the five subsystems; include the Administration subsystem plus the order four subsystems you previously defined: Customer account subsystem $($like customer account$),$ Pickup request subsystem $($like sales$),$ Package delivery subsystem $($like order fulfillment$),$ Routing and scheduling subsystem. $3)$ Create project iteration schedule for each subsystem. The project consultant is planning to assign one team of two people to this project, and the subsystems will be built consecutively. Based on the answers you provided in chapter $8,$ combine your four individual schedules into total project iteration schedule. $4)$ Create a work breakdown structure $($WBS$)$ for the first iteration of the project as you have outlined it$.$ Estimate the effort required for each task in the WBS$.5)$ Enter the WBS into Microsoft Project to create a detailed work schedule.
