Study Notes

Course Information

Course Title: Software Requirements Analysis and Design
Course Code: ACS2913
Instructor: David Tenjo
Semester: Fall 2022
University: The University of Winnipeg

Chapter 2 Outline

RMO Consolidated Sales and Marketing System Project
Systems Analysis Activities
What are Requirements?
Stakeholders
Information Gathering Techniques
Models and Modeling
Documenting Workflows with Activity Diagrams

Learning Objectives

Describe systems analysis activities
Explain the difference between functional and non-functional requirements
Identify and understand different kinds of stakeholders and their contributions to requirement definition
Describe information-gathering techniques and when each is best applied
Describe the role of models in systems analysis
Develop UML activity diagrams to model workflows

Overview

Chapter 1 introduced System Development Life Cycle (SDLC) and demonstrated its use for a small project
Systems analysis activities are detailed in this chapter
This chapter expands the SDLC processes to cover a wider range of concepts, tools and techniques
A larger Ridgeline Mountain Outfitters (RMO) project will be used to illustrate analysis and design
Core process 3: Discover and understand details of the problem or need—the focus of systems analysis

Ridgeline Mountain Outfitters (RMO)

RMO has elaborate information systems that support operations and management
Customer expectations, modern technology, and competitive pressures led to the need for a new system to support sales and marketing
A new Consolidated Sales and Marketing System was proposed as a major project from the RMO strategic planning process

RMO Information Systems Strategic Plan

Technology architecture: set of computing hardware, network hardware, topology, and system software employed by the organization
Application architecture: information systems that support the organization (information systems, subsystems, and supporting technology)

RMO Existing Application Architecture

Supply Chain Management (SCM): 5 years old, Java/Oracle. Interfaces with SCM tradeshow system
Phone/Mail Order System: 12 years old, Visual Studio/MS SQL. Reached capacity, minimal integration
Retail Store System: Older package solution, minimal integration
Customer Support System (CSS): Web-based, evolved over years, minimal integration

Proposed Application Architecture

Integrate SCM and New CSMS
Diagram shows integration of SCM, online sales, phone sales, retail sales, and customers to the proposed Consolidated Sales and Marketing System

New Consolidated Sales and Marketing System (CSMS)

Sales Subsystem, Order Fulfillment Subsystem, Customer Account Subsystem, and Marketing Subsystem
Integrates online, phone, and retail stores
Tracks shipments, rates products and services
Provides shopping history, linkups, and rewards ("mountain bucks")
Includes promotional packages and partner relationships for more complete merchandise information and reporting

Systems Analysis Activities

The New Consolidated Sales and Marketing System (CSMS) requires understanding and discovering extensive and complex business processes and business rules
The SDLC indicates the project starts by identifying the problem, obtaining approval, and planning the project (as seen in Chapter 1)
Details of project planning activities are omitted to get to the core of systems analysis-discovering and understanding
Gather Detailed information, Define requirements, Prioritize requirements, Develop user-interface dialogs, Evaluate requirements with users

Types of Requirements

Functional requirements: Activities that the system must perform. Shown as use cases in Chapter 1
Non-functional requirements: System constraints and performance goals. Example types are usability, reliability, performance, and security requirements

FURPS+ Requirements Acronym

Functional, Usability, Reliability, Performance, Security
Even more categories...

Additional Requirements Categories

Design constraints: Specific restrictions for hardware and software, languages, tools, and protocols
Implementation requirements: Specific languages, tools, protocols, etc.
Interface requirements: Interface links to other systems
Physical requirements: Physical facilities and equipment constraints
Supportability requirements: Automatic updates and enhancement methods

Stakeholders

Stakeholders are people with an interest in the successful implementation of the project
Internal stakeholders: Persons within the organization (e.g., employees)
External stakeholders: Persons outside the organization (e.g., customers, suppliers)
Operational stakeholders: Persons regularly interacting with the system (e.g., order clerks)
Executive stakeholders: Persons who don't directly interact but use the information or have financial interest.
Stakeholders examples for RMO related to CSMS system: phone/mail sales order clerks, warehouse and shipping personnel, marketing personnel. , marketing, sales, accounting, and financial managers, senior executives, customers, external shippers (e.g., UPS and FedEx)
Stakeholder organization chart for RMO is included

Summary (Various)

Systems analysis activates correspond to core SDLC ("Discover and understand details")
System projects originate from information system strategic plan, which includes technology architecture plan and application architecture plan
RMO CSMS Project will be used to illustrate analysis and design
Systems analysis involves defining system requirements (functional and non-functional)
Analysis activities include gathering detailed information, defining requirements, prioritizing requirements, developing user-interface dialogs, and evaluating requirements with users.
FURPS+ (Functional, Usability, Reliability, Performance, Security) is an acronym for system requirements.
Stakeholders include those interested in project success (internal, external, operational, executive).
