Develop a deliverable-oriented WBS for a surprise birthday party for a friend or relative (perhaps even your instructor?). Be sure to define a measure of success for this party and include milestones. Using the following phases as a guide, develop a WBS for an IT project that will allow Husky Air to keep track of all scheduled maintenance for its chartered aircraft. For each phase, define a deliverable, several activities or tasks, and a milestone,

!.0 Conceptualize and Initialize Project 2.0 Develop Project Charter and Plan 3.0 Analysis 4.0 Design


5,0 Construction

6.0 Testing

7.0 Implementation

8.0 Close Project

9.0 Evaluate Project Success

Using the information below, complete a function point analysis in order to use the basic COCOMO model to estimate the duration and number of people needed to develop an application using C++. Assume that the project is relatively simple and straightforward and that the project team is familiar with both the problem and technology. You can perform the calculations by hand, but feel free to use an appropriate software tool
