Options and Priorities• Four alternatives to in-house development
– Outsourcing– Licensing– Using ASP– Allow users to develop
• Deciding factor usually cost• License low cost and immediately available
– Best choice• ASP immediately available and small startup fee

Options and Priorities (continued)
• Third best option is allowing users to develop
• Outsource if non-IT employees cannot develop IS
• Many factors in addition to cost and quality
• Alternatives not fully comparable

Outsourcing
• Outsourcing has two meanings:– Commission development of application to
other organization– Hire services of other company to manage
services
• May not encompass development

Outsourcing Custom-Designed Applications (continued)
• Tailored development requires organization to fund all costs
• IS personnel constantly in use• Production schedules may be delayed• Less likely to be compatible with other
organizations• Offshoring: outsourcing to India, China,
Philippines, etc.

Software As a Service• Application service provider (ASP):
organization that offers software on Web
• Software as a service (SaaS): applications through Web
• No software installed
• Files may be stored on local storage device
• ASP may rent software

Caveat Emptor• ASP may be disappointing
– Scope of services – Reliability
• Manager guidelines– Check ASP history– Check ASP financial strength– Ensure you understand price scheme– Get list of provider’s infrastructure– Craft service contract carefully
![Page 33: Ch12](https://reader036.vdocuments.net/reader036/viewer/2022062514/55901c571a28ab3b508b46f9/html5/thumbnails/33.jpg)

Caveat Emptor
• Uptime: proportion of time ASP systems up– No ASP has 100 percent uptime– 99.999 percent uptime recommended
• Less than 5 minutes a year
• Storage service provider (SSP): rents storage space– Store files remotely
