Final answer:
For a company with no expert IS department, outsourcing and RAD are suitable systems development methods. Outsourcing leverages external expertise, while RAD facilitates fast development with iterative cycles.
Step-by-step explanation:
When a company does not have an expert Information Systems (IS) department and is considering systems development methods, outsourcing and Rapid Application Development (RAD) are appropriate options. Outsourcing involves hiring an external organization with expertise in system development to handle the project, whereas RAD is a type of agile software development that focuses on quick and iterative release cycles, which could be manageable with minimal internal expertise. Both approaches accommodate for a lack of in-house IS knowledge and can be adapted to the company's specific requirements.
