Explain one of the 'rapid' methodologies e.g., Scrum, Extreme Programming (XP), and compare/contrast it with R.U.P. using the RUP lifecycle phases as the starting point for comparison. (30 marks) b) A software engineer has to design a kitchen planning program for IKEA. The cupboards (which come in a range of sizes and with different internal fittings) and main kitchen appliances (fridge, oven, sink etc.) have to be displayed and can be dragged and dropped onto the kitchen plan. The individual elements can be rotated and moved, and their positions 'snapped' to a displayed grid. The user can select different colours for the cupboards and the kitchen layout can be displayed in 3d. The user can also get the program to produce a list of the items to pick up in store and generate an itemised bill for the kitchen. Explain ONE method that the software engineer would use in trying to identify the objects for the problem specified above and give examples of how it might work for this project (20 marks)
