Gary NormanRisks and Benefits.
Regardless of the development method, launching a new information system involves risks as well as benefits.
The greatest risk occurs when a company tries to decide how the system will be constructed before determining what the system needs to do.
Instead of putting the cart before the horse, a company must begin by outlining its business needs and identifying possible IT solutions.
Typically, this important work is performed by systems analysts and other IT professionals.
A firm should not consider implementation options until it has a clear set of objectives.
Later on, as the system is developed, a systems analyst’s role will vary depending on the implementation option selected.
Systems Analysis and Design
Systems analysis and design is a step-by-step process for developing high-quality information systems.
An information system combines information technology, people, and data to support business requirements.
For example, information systems handle daily business transactions, improve company productivity, and help managers make sound decisions.
The IT department team includes systems analysts who plan, develop, and maintain information systems.
