Why large teams? • Most software systems are extremely complex • Often: over 100,000,000 lines of code • Thousands of person-years! • Must have a solid design, architecture and plan before programming starts
Skills needed • Solid math skills • More importantly: creative problem-solving • Requirements: what does the customer need? • Design: satisfying the need • Development: infinite ways to implement any design – want one that is clear, maintainable • Testing: finding errors • Other great things • Flexible – many telecommute; set hours (within limits) • New technologies, languages • Learn lots about different areas
Placement & Salaries • SE Placement • Near 100% • CS Placement • About 80 - 90% • Salaries • Vary from middle $40K to $90K • Average in low to mid $50K • SE average is higher than CS average • CS & SE among 10 fastest job growth next 10 yrs
