Que stion 1 On your level 0 diagram you have a process #2 and when you create a level 1 diagram for process #2, you might have processes like: a. 2.1, 2.21, 2.3 c. 2A, 2B, 2C d. 2-A, 2-B, 2-C e. 2-initial, 2-main, 2-end 1 /1 Question 2 A well-constructed use case makes developing a data ﬂow diagram fairly straightforward. False 2 /2 Question 3 Data ﬂow diagrams are: a. Usually created by users and reviewed by analysts b. Usually jointly created by analysts and users d. Usually created by the project champion and reviewed by the project team e. Usually created by business analyst and reviewed by the infrastructure analyst 1 /1 Question 4 Data (like Year-to-date totals) that come from a data store and are used in a process (like 'Calculate YTD Totals') and then the updated amounts are written back to the data store - can be drawn on a DFD model as a two-headed arrow. True b. 2-1, 2-2, 2-3 True c. Usually created by the project team and reviewed by users for correctness False 1 /1 Question 5 Context diagrams ( which represents a complete system.) show the entire system in context with the environment (like external entities). False 2 /2 Question 6 Processes in data ﬂow diagramming are represented by: b. Arrows c. Rectangles that is open on the right end d. Enclosed rectangles e. Circles 1 /1 1 /1 2 /2 Question 7 Process models are only used to document the current system (that is, the "as-is" system), since that is the system the users know and is the system that will be modiﬁed. True Question 8 Iterations are not used in good DFD design. True Question 9 Carlos has a Level 0 DFD diagram where one of the external entities is the "internal Revenue Service" - and he has a data store called "Tax Rate Table". He has drawn a data ﬂow arrow from the Internal revenue Service to the data store as the data has been loaded into the Tax Rate Table prior to the processing. What would be true? a. This is correct b. This is incorrect, 'data at rest stays at rest until moved by a process' so he needs a process (like 'load Tax Rate Table') ﬁrst in this system d. This is almost correct. The correct diagram would be a dashed line indicating that the loading of the data was implied prior to the start of this process e. This is incorrect. What should happen is an 'external process' should be called at the start of the process - like "Call IRS for data load" 1 /1 Question 10 Project teams usually use process modeling tools or CASE tools to draw process models. False 1 /1 Question 11 True a. Rounded boxes False False c. This is incorrect - he doesn't need a data ﬂow as the data was loaded into the Tax Rate Table someplace else (within the payroll system someplace, but not in this process) True

True Question 6 Cindi Flores distributed 'white-papers' on RFID, ERO, GPS and SOA to a user-management grop. She then asked them to 'think outside the box' on where these technologies could be used in the company. This would be an example of 'technology analysis'.
