Software Development 1. Explain why the cost to identify and remove a defect in the early stages of software development might be 100 times less than the cost of removing a defect in software that has been distributed to customers. What are the implications for a software development organization?  2. Your company is considering using N-version programming with three software development firms and three hardware devices for the navigation system of a guided missile. Briefly describe what this means, and outline several advantages and disadvantages of this approach.  3. Your organization develops accounting software for use by individuals to budget and forecast their expenses and pay their bills while keeping track of the amount of money in their savings and checking accounts. Develop a strong argument for the management of your firm as to why the firm must conduct an assessment of its current software development practices.  4. Discuss why an organization might elect to use a separate, independent team for quality testing rather than the group of people who originally developed the software.
