Slide 4
Key Ideas
Projects being when someone sees an opportunity to create business value from using information technology.Feasibility analysis is used to aid in the decision of whether or not to proceed with the IS project.

Slide 5
Key Ideas
The project sponsor is a key person proposing development or adoption of the new information technology .The approval committee reviews proposals from various groups and units in the organization and decides which to commit to developing.

IDENTIFYING BUSINESS VALUE
![Page 7: Slide 1 Systems Analysis and Design with UML Version 2.0 An Object-Oriented Approach, Second Edition Chapter 3: Project Initiation Alan Dennis, Barbara](https://reader035.vdocument.in/reader035/viewer/2022062516/56649e165503460f94b00b54/html5/thumbnails/7.jpg)
Slide 7
Business Value
Business value is determined by weighing the cost against the benefits – both tangible and intangible.
Tangible benefits are quantifiable and measurable. --save 500,000 dollars in services, etc.Intangible benefits are improvements that are suspected to be able to give tangible benefits but are not as measurable. -- improve customer service.
