1) A project manager at COMSOFT Corporation has collected statistics on the organization’s software development process. He has the size of each project in number of lines of code for the past 20 projects and the number of design errors discovered in design reviews for each project. .
Describe what type of control chart you can use and how do you calculate the control limits to check if the software design process in this organization is in control.
2) A project manager at System Design Corporation has collected the following data on the size of software programs and the length of programming time. The company is bidding on a new system that is estimated to consist of 250000 lines of code. Please use the data to find the functional relationship of the coding time to the program size and estimate the number of days it would take to code the new system.
