1.264 Midterm Exam Solutions Fall, 2004 1. Software process. (33 points) a. List at least 5 errors made by this development team in their execution of this project. (11 points) i. No resource estimates (function points, lines of code, schedule months, person months) were made at the start of the project. Chris gave an off-the-cuff estimate when asked at the first meeting. ii. No uncertainty was communicated to the steering committee. Chris gave a point estimate, and he didn’t state any assumptions on the size of the project, complexity of requirements, etc. iii. No discussions of tradeoffs in functions or team size to meet the 6- month date were held. Chris should have done this as requirements became complex, and even at the start of the project. No principled negotiation occurred, and requirements gathering was not managed aggressively, as the short timeframe required. iv. Chris did not communicate the true schedule as the project progressed. The real estimates were not given, and no proactive information was given before there was a problem. If requirements took twice as long as expected, so would every other part of the project, and this was not addressed. The project had poor visibility with its management. v. The team did not use the spiral model (or other appropriate model such as evolutionary prototyping, etc.). They used a waterfall, which is inappropriate for rapid development, which this project clearly required.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
