Information Gathering and Eliciting System Requirements
 

Assignment Overview
 

The Case for this Module discusses the interview process and modeling tools and techniques for users and developers to understand current and new systems requirements. The primary purpose of the systems analysis is to gather and document systems requirements. To gather information, the business analyst conducts interviews, administers questionnaires, and may conduct Joint Application Development (JAD) sessions. Compared to traditional interviews, JAD sessions are the most expensive, and the meetings can easily become out of control if too many participants attend. Large projects may require separate JAD sessions because the purpose is to obtain system requirements by specific processing departments. Small sessions are highly productive and deliver accurate requirements since participants are working towards a common goal.

The Feasibility Study
 

Assignment Overview
 

IT systems are a major capital investment and the systems analyst is called to investigate the feasibility of a system and help answer the questions – Will the system pay for itself? In how long will it pay off? Are the
other technologies that will have a better return on the investment? Module 3 emphasizes the need of making management recommendations in a proposal called the feasibility study report. Feasibility is defined as the value that an IT system will provide to the organization in terms of tangible and intangible benefits.
 

Following the problem analysis definition and requirements, the feasibility study is prepared considering elements such as economic, technical, operational, schedule, legal/contractual, and political challenges. This analysis determines the readiness and worthiness of an IT system, and the category domains are defined
as follows.
 

Economic – What is the TCO (total cost of ownership)? Is the ROI positive?
Technical – Is hardware available? Do we need to purchase it?
 

Operational – Are resources available? Do we need training and change management plans?
Schedule – Can the system be available within a reasonable time?
 

Legal – Are permissions being filed with state and federal regulations?
Political – Is the system in compliance with federal and state agencies?
 

Most analysts agree that the first four categories are sufficient to analyze a system, but legal and political criteria are used to evaluate R&D projects or projects using emerging technologies.
