Questions! • What’s an SE project like? • What problems do SE projects face? • How do SEs overcome these problems? • How will this course teach you?
Questions! • What’s an SE project like? • What problems do SE projects face? • How do SEs overcome these problems? • How will this course teach you? Caveat: Every project is an individual
Characteristics of SE Projects Large Scale Customers Teams of Developers http://flic.kr/p/83MmEP http://flic.kr/p/sAPm8 http://flic.kr/p/hnrKZ
What is the measure of a successfulsoftware engineering project?
What is the measure of a successfulsoftware engineering project? Customer Satisfaction http://flic.kr/p/hnrKZ * OK, effect on society and humanity matters too, but humor me…
What do customers want? Software that Meets their needs, On time, and On budget
Unfortunately, satisfying customers is hard… http://flic.kr/p/7pGoCd Have you ever been a dissatisfied customer?
The “Software Crisis” Since the 1960s (More like a depression) Of 28,000 projectscompleted in 2000… 2002 Study: 78% of orgs landed in court (Cutter Consortium) (Standish Group)
Although stats improving, challenges remain… Recent headlines (Oct 2013–Aug 2014): • Tech Problems Plague First Day Of Health Exchange Rollout • Health Exchange Tech Problems Point To A Thornier Issue • It's Easy To Blame The Canadians For HealthCare.gov Problems • Sebelius: Hold Me Accountable For HealthCare.gov Debacle • Add Security To The List Of HealthCare.gov Tech Issues • Oregon's State Exchange May Be Worse Than HealthCare.gov • Could A Tech Giant Build A Better Health Exchange? Maybe Not • Official In Charge Of Creating HealthCare.gov Steps Down • Giving Up On Its Obamacare Exchange No Cure For Oregon's Ills • Oregon Sues Oracle For "Abysmal" Healthcare Website ( ) ( )

Problem: Requirements http://flic.kr/p/a5UCs
“The customer is always right!” http://flic.kr/p/9XVhuK But … Customers may change their minds Customers may not agree with each other Customers may not know exactly what they want
Problem: Cost estimation http://flic.kr/p/anRib
Spectacular failure: Denver Int’l Airportbaggage-handling system
Problem:Bugs http://flic.kr/p/6Pxibn
Spectacular failure: Therac-25 radiation therapy machine
Problem: Maintenance http://flic.kr/p/5U934t
All successful software will change over time But such change can lead to design erosion

Apply the SWEBOKSoftware Engineering Body Of KnowledgeSWEBOK Guide: http://www.computer.org/portal/web/swebok
One possible definition ofSoftware Engineering:Applying SWEBOK to softwarecreation and evolution So what’s in this SWEBOK anyway?
15 Knowledge Areas (KAs) • Software Requirements • Software Design • Software Construction • Software Testing • Software Maintenance • Software Configuration Management • Software Engineering Management • Software Engineering Process • Software Engineering Models and Methods • Software Quality • Software Engineering Professional Practice • Software Engineering Economics • Computing Foundations • Mathematical Foundations • Engineering Foundations
15 Knowledge Areas (KAs) We’ll mainly focus on this subset • Software Requirements • Software Design • Software Construction • Software Testing • Software Maintenance • Software Configuration Management • Software Engineering Management • Software Engineering Process • Software Engineering Models and Methods • Software Quality • Software Engineering Professional Practice • Software Engineering Economics • Computing Foundations • Mathematical Foundations • Engineering Foundations
Questions! • What’s an SE project like? • What problems do SE projects face? • How do SEs overcome these problems? • How will this course teach you? To effectively apply approachesrequires experience
Course Goals • Significant software project • Team skills • Communication skills • Project management
What type of software willyou build for the project? Web Apps!
Why web apps? • Create apps every bit as dynamic, interactive, and custom tailored as native apps • Avoid deployment problems • Reach people world wide http://flic.kr/p/9DTDXi
What programming language(s)? http://spectrum.ieee.org/static/interactive-the-top-programming-languages
Course Structure • Rails Web App Boot Camp (6 weeks) • Homeworks • Team Project • Initial Planning (3 weeks) • Alpha Iteration (3 weeks) • Beta Iteration (3 weeks) • Pop quizzes throughout • Two exams • Each project iteration ends with demos
Grading • 40% Team Project • 15% Regular Productivity • 5% Above & Beyond • 5% Initial Planning • 5% Alpha Milestone • 10% Beta Milestone • 36% Exams (18% ea.) • 14% Homework and Quizzes • 10% Participation
Policies of Interest • No cheating! • I use plagiarism detection system! • Participate! (or lose participation point) • Be here at beginning of class • Stay until the end • Be engaged in between! • Expect seating chart • Bring laptops, but…
