Module 2

Essential feature of developing a new system which may contain processing or gathering of data, handling the activities of business, producing information and supporting the management.

Ncludes examining the existing system and gathering details to find out how it works, what are the requirements and where improvements should be made

Predicts the characteristics of system based on previous experience which include certain problems or features and requirements for a new system

Studying the current system and documenting its features for further analysis.

Is at the heart of system analysis where analyst documenting and describing system features using fact-finding techniques, prototyping, and computer assisted tools.

Includes analysis of factual data, identification of essential requirements, and selection of Requirement-fulfillment strategies.

Includes the analysis of data which determine the requirement specification, description of features for new system, and specifying what information requirements will be provided.

Used in requirement gathering to get as many ideas as possible from group of people

Reviewing the documentation of an existing system can help when creating AS–IS process document, as well as driving gap analysis for scoping of migration projects.

Gathering of people who are representative of the users or customers of a product to get feedback

reviewing the touch points with other external systems is important to make sure we don’t overlook requirements that aren’t immediately visible to users.

Stakeholders and users are critical to creating the great software. Without understanding the goals and expectations of the users and stakeholders, we are very unlikely to satisfy them. We also have to recognize the perspective of each interviewee, so that, we can properly weigh and address their inputs. Listening is the skill that helps a great analyst to get more value from an interview than an average analyst.

Observing users, an analyst can identify a process flow, steps, pain points and opportunities for improvement.

Relatively modern technique for gathering requirements. In this approach, you gather preliminary requirements that you use to build an initial version of the solution

Can be very effective for gathering requirements. More structured than a brainstorming session, involved parties collaborate to document requirements.

When a migration project does not have access to sufficient documentation of the existing system, reverse engineering will identify what the system does

When collecting information from many people – too many to interview with budget and time constraints
