3. Look a lot ALIKE! Pinchas Zukerman Mark Zuckerberg

4. Take another look

5. Obama?

6. Maybe we need some help from computer vision… • Let’s age Zuckerberg a little! “FaceGenModeller 3.5”

7. This is the type of technology we use with national security • Do you trust an avatar that looks more like you?

9. Administration • Assignment 4: Due Thursday Before Class • If you missed class, come get it. • Survey: AnimalLingo Party • Class Evaluations- Possibly Today! • Quiz 4 Tomorrow: Learning Objectives

10. Quiz 4: Learning objectives • Define or describe 1) Enterprise Resource Management (ERP), 2) Supply Chain Management, and 3) Customer Relationship Management systems. • Compare and contrast the waterfall model and Iterative and Incremental Development. • Explain what happens in the planning stage of the Software Development Life Cycle • Explain why it is important to understand company culture. • Define Project Management. • What are the three constraints of project management

11. Today’s Learning objectives • Specify requirements by using an event table • Create a context diagram • Create DFD fragments • Create a decision tree • Define Project Management • List the three constraints of project management • Explain how to manage each constraint

12. Review of context diagrams • Context Diagrams contain External Agents, Data Flows, and the System itself. • Draw the following context diagram representing Officer and Traffic Violator transactions. • Officers record violations. • Traffic Violators are fined through the system and also pay fines through the system.

13. Context diagram Violation Info Fine Traffic System Officer Traffic Violator Payment

14. Review of data flow diagrams • Complete this event table.

15. Create dfd fragments from this event table

16. Lets keep going

17. Remember this example

20. Thought? • Any questions related to Assignment 4? • Can I use this to develop an Android App?

21. Diagram 0: All together Enrollment Request Student 2 Enroll Student Academic Department Schedule Schedule Data Enrollment Data 1 Schedule Course 3 Produce Class List Faculty Member Class List Course Data

22. Diagram 0: a little less abstraction • Diagram 0 contains all DFD fragments. Don’t worry… you won’t be required to perform this feat! But I will show you what one looks like. • Just focus on creating event tables, context diagrams, and DFD fragments. • Rome wasn’t built in a day.

23. Some very bad things • Black Hole – data goes into a process and nothing comes out! • Miracle – nothing goes into a process and data comes out! Enrollment Request 2 Enroll Student Student Course Data 2 Enroll Student Enrollment Data Student Schedule

24. Decision trees

25. The decision tree • The Decision Tree is another Systems Analysis tool that summarizes decision logic.

26. Decision trees are based on decision variables • To decide delivery charge, we look at the following variables: • Purchase Cost • Is it greater or less than $250? • Number of Items Purchased • Is it greater than or equal to four? Or less than or equal to three? • Delivery Day • Is it next day delivery? 2nd day delivery? Or 7th day delivery?

27. Purchase > 250? No Yes <=3 <=3 >=4 # items >=4 Delivery day next 2nd next next 7th 2nd 7th 7th 2nd next 7th 2nd 25 10 7.50 10 7.50 6 35 15 10 9.50 7.50 6 DECISION MADE ON DELIVERY COST (in $)

28. You try a decision tree based on these variables • By looking at the following variables, we can decide whether or not to expedite delivery. • Customer Type • Are they a new customer or not? • Back Order • Is the item on back order more than 25 days or not? • Return Instructions • Are detailed instructions to be included or not?

31. Project management

32. Systems analysis and design • Why was the Systems Development Life Cycle so important? • Because the majority of IS projects fail

33. Why do projects fail? • Some primary reasons why projects fail include the following: • 1. Incomplete or changing system requirements • 2. Poor Project Planning • 3. Unclear objectives • 4. Limited User Involvement • 5. Lack of executive support • 6. Lack of technical support

34. What helps projects succeed? • 1. Clear system requirement definitions • 2. Substantial user involvement • 3. Support from upper management • 4. Thorough and detailed project plans • 5. Realistic work schedules and milestones

35. note • “The technology is too complex” is generally not a reason for project failure. • Projects fail most frequently because project management has failed.

36. Project management

37. What is Project Management? • Project management is the application of knowledge, skills, tools and techniques to a broad range of activities in order to meet the requirements of the particular project. • More than 16 million people employed by businesses regard their profession as project management

38. What is a project? • A project is a temporary endeavor undertaken to achieve a particular goal • A project must have a unique purpose • A project must have a fixed lifespan • A project requires resources, often from various areas • A project involves uncertainty

39. The Triple Constraint Projects are said to be bound by a Triple Constraint of: • Time (When do we have to be done?) • Resources (How much money do we have?) • Scope (What do we need to accomplish?) Whereby any changes to one of the factors will effect the outcome of the project.

40. Constraint Matrix

41. Managing: Time

42. Time • Why is time a constraint? • Time is Money! • How do we manage time?

43. Time as a constraint Project managers can use PERT (Project Evaluation and Review Technique) and GanntCharts to monitor and model the time constraints of a project.

44. GANTT Chart

45. Terms • Critical Path • Slack

46. PERT Chart

47. Tools to help • Microsoft Project • Open Workbench

48. Pert Chart Example • How do we create a peanut butter sandwich

49. Managing Resources

50. Food for thought? • What resources are constrained?
