Project milestones were split up so you concentrate on each layer (Model, then View, and then controller as the final milestone). Other option would have been to define the milestones based on feature and you develop the entire MVC based on feature such as book list or maintain book.

(a) Discuss pros and cons of each approach, eg, how your project would have been different if each of the milestones were feature based and you had to implement the entire feature vs what was currently laid out.

(b) If you had to implement MVC like functionality in the future, would you separate work based on feature or keep it same way as the project milestone. Discuss why.
