PE $1-5.$ Read the I$2$C$2$ case study in Appendix A for I$2$C$2$s existing clinic and pharmacy business and the project to update I$2$C$2$s systems supporting that business. Consider that for this clinic and pharmacy business, I$2$C$2$ has an existing, well$-$understood set of business processes. Further, the systems supporting that business run well and already provide many of the features that I$2$C$2$ needs. Finally, I$2$C$2$ has been able to clearly describe the new software features needed to enhance those systems. Given this, explain the following:

a$.$ How much is this systems project like inventing a new gadget?

b$.$ How much is this systems project like creating blueprints to add rooms to a house?

c$.$ Given the previous points, would you suggest an agile approach using emergent requirements versus a plan$-$driven approach using big requirements up front $($BRUF$)?$ Why?
