List and describe the five alternatives to traditional, on-premise CRM systems. Suppose your organization cannot afford an on-premise CRM system; which of these alternatives would you choose to implement and why? In your answer, you should consider the advantages and disadvantages of each option.

On-demand = vendor-hosted CRM system; benefit = cheaper (SaaS); limitation = unreliable vendors, modification difficult/impossible, integrating with existing software difficult/impossible, security and privacy
Mobile = CRM through mobile devices; benefit = interact with customers anywhere at any time; limitation = small screens and internet isn't everywhere (limitation not in book)
Open-source = source code available; benefit = free, lots of applications, easy to customize, updates and bug fixes quickly available; limitation = quality control, no central authority for overseeing quality (depend on volunteers), must have same IT platform in place as the one on which the open-source CRM system was developed
Social = social media to get customers involved in collaborative conversations; benefit = getting customers involved and meet customer needs quickly and unexpectedly (Morton's Steakhouse example); limitation = customers can say bad things (limitation not in book)
Real-time = organizations are able to respond to customer product searches, requests, complaints, comments, ratings, reviews, and recommendations in near real-time; benefit = meet customer needs quickly and efficiently (Southwest Airlines example); limitation = privacy (limitation not in book)
