She needed answers to the following questions: Was the software she needed available for her to purchase? If so, how should she approach the process of buying hardware and software and selecting a vendor? 17- Introduction How do companies go about developing software in-house, and is this the best approach for SM? How extensively should the system make use of end-user-developed software? If the company decided to develop the system in-house, should it try and speed up the development process by using prototyping or computer-assisted software engineering? 17- Introduction Should SM just make the needed improvements to its existing system, or should it consider reengineering its business processes and then develop a system to support the new processes? Was outsourcing the information system a viable alternative to obtaining a new system?
