Part 1: Requirements Case Study

Purpose: Hands-on Case Study to Describe System Requirements

Analyze the Amazon.com website. Create a list of functional and nonfunctional business

requirements that the system meets. Functional requirements begin to define how the

system will support the user in completing a task. Nonfunctional requirements are the

quality attributes, design, and implementation constraints, and external interfaces which a

product must have.

For functional requirements identify at least three requirements and provide at least 3

examples for that requirement. You will need to label each function. Use the outline format

so that each requirement is clearly identified with unique numbers.

At least one functional requirement (with three examples) must be related to

process-oriented concerns (a process the system must perform or do)

At least one functional requirement (with three examples) must be related to

information-oriented requirements (information the system must contain).

•

A third functional requirement (with at least three examples) of your choice. You

need to identify what this functional requirement relates to.

•

A fourth functional requirement (with at least three examples) of your choice. You

need to identify what this functional requirement relates to.

For nonfunctional requirements provide examples for each of the four categories:

Operational (at least two examples)

Performance (at least two examples)

Security (at least one example)

Cultural/Political (at least one example)

Documenting your work and evidence is important for systems analysis. Include at least one

screenshot of your visit to Amazon. Write a short paragraph (at least 50 words) explaining

how you arrived at your functionality requirements from your exploration of the site. Note

how you determined the functional requirements./nPart 2: System Requirements Documentation Utilizing a Business Case

The Business Case

Purpose

You as the Systems Analyst have practiced analyzing business cases and will now produce

documentation that may lead to a viable project. You will also be asked to start the process

of transforming those business requirements into more detailed system requirements,

describe what the new system must do to provide the needed value to the business.

This assessment is considered a "Business Case." An outline is provided to help get you

started. You can search online and refer to Chapter 1 for additional details and appropriate

ROI formulas or costs. You may create additional details or constraints to define your work.

Process

Review the scenario presented. You will be as asked to analyze the situation, develop a

proposed system solution, perform an analysis based on the information presented, and

develop a method to gather more information to validate your requirements.

Assessment Instructions and Requirements

Scenario: Mystic Brewery is a local start-up company formed by two brothers and partners,

Jake and Pete. Each has their own brewing equipment and they have recently purchased a

small building that was once a car sales/body shop to combine their previous disparate

businesses into one microbrewery. They have converted part of the back-mechanic area

into a brewing station and the front sales and reception desk into a small taproom. There is

no food service. There is ample space inside that can be used for expanded capacity or/nrefer to the assessment requirements, which include a title and reference page as well as

formatting specifications in APA style.

Problem Definition

Paragraph 1: Give more detail to articulate the problem.

Paragraph 2: Propose at least two potential types of information system solutions to solve

the problem.

They may be similar but must have at least one component that is different - and you must

identify what kind of Information System or Systems you are proposing:

Executive Information Systems (ESS)

Decision Support Systems (DSS)

Management Information Systems (MIS)

Transaction Processing Systems (TPS)

Artificial Intelligence and Expert Systems

Cost-Benefit Analysis/ROI (for BOTH alternatives)

Table(s):

Provide one-time purchase costs (hardware and/or software), including quantity, brands,

and dollar amounts.

Provide ongoing costs (services), including vendor and dollar amount per month or year.

Include the direct URL for any cost listed.

Paragraph: Explain your ROI findings in paragraph form.

HINT: It is important to explore alternatives to help in decision making. You will want to

provide cost benefit analysis for BOTH possible alternatives.

Recommendation

Paragraph: Choose a solution! Write a paragraph that is meant to convince the client that

your solution is in his/her best interests./nParagraph 1: More information is clearly needed to confirm your assumptions, validate your

hypotheses and begin to flesh out the next steps and details of your proposal. Write a one-

paragraph method to gather more information to transform your proposal into more specific

requirements. Think about ways to gather the information necessary to complete your

feasibility study.

Table(s):

Feasibility:

Operational/Organizational Feasibility

Describe at least two factors that would show the project is operationally feasible.

Economic Feasibility

Describe at least two factors that show the project is economically feasible.

Gathering Requirements: Database

Write at least four questions in your quest to gather ideas for organizing data into a

database.

Gathering Requirements: Security

Write at least two questions in your quest to gather ideas for ensuring data security.

Conclusion:

Short Paragraph: Briefly summarize the problem, your solution, project goals, and how it

aligns to the company's mission. Connect your feasibility requirements back to your original

solution.
