RMO has

elaborate set of information systems that supports operations and management.

what led RMO

Customer expectations, modern technological capabilities, and competitive pressures led RMO to believe it is time to upgrade support for sales and marketing

what was proposed

a New Consolidated Sales and Marketing System

What kind of project

This is major project that grew out the RMO strategic planning process of

RMO

Ridgeline Mountain Outfitters

What is The information systems strategic plan ?

The information systems strategic plan is based on the overall strategic needs of the organization

What the information systems strategic plan includes?

The information systems strategic plan includes definition of the technology architecture and the application architecture needed by the organization

Technology architecture?

the set of computing hardware, network hardware and topology, and system software employed by the organization

Application architecture—

the information systems that supports the organization (information systems, subsystems, and supporting technology)

What is Supply Chain Management (SCM)?

5 years old; Java/Oracle


Tradeshow system will interface with SCM

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 system; evolved over the years, minimal integration

New Consolidated Sales and Marketing System (CSMS)

1.Sales Subsystem(Integrates online, phone, and retail stores)


2.Order Fulfillment Subsystem(Track shipments, rate products and services)


3.Customer Account Subsystem(Shopping history, linkups, “mountain bucks” rewards)


4.Marketing Subsystem(Promotional packages, partner relationships, more complete merchandise information and reporting)

(Systems Analysis Activities)


What New Consolidated Sales and Marketing System (CSMS) requires ?



1. The New Consolidated Sales and Marketing System (CSMS) will require discovering and understanding extensive and complex business processes and business rules



What SDLC indicates?

The SDLC indicates the project starts with identifying the problem, obtaining approval, and planning the project

what is purpose (Systems Analysis Activities)?

To get to the heart of systems analysis, this text skips right to analysis activities generally and the specifically for the RMO CSMS project

What is Systems Analysis Activities?

1.Gather Detailed Information(Interviews, questionnaires, documents, observing business processes, researching vendors, comments and suggestions)


2.Define Requirements(Modeling functional requirements and non-functional requirements)


3.Prioritize Requirements(Essential, important, vs. nice to have)


4.Develop User-Interface Dialogs(Flow of interaction between user and system)


5.Evaluate Requirements with Users(User involvement, feedback, adapt to changes)

What Are Requirements?

1. System Requirements=


(Functional requirements, Non-functional requirements)


2.Functional Requirements– the activities the system must perform(Business uses, functions the users carry out,Use cases in Chapter 1)


3.Non-Functional Requirements– other system characteristics(Constraints and performance goals)

FURPS+ Requirements Acronym

1.Functional requirements


2.Usability requirements


3.Reliability requirements


4.Performance requirements


5.Security requirements



Model?

a representation of some aspect of the system being built

Types of Models

1.Textual model– something written down, described


2.Graphical models– diagram, schematic


3.Mathematical models– formulas, statistics, algorithms

Unified Modeling Language (UML)

Standard graphical modeling symbols/terminology used for information systems

Reasons for Modeling

1.Learning from the modeling process


2.Reducing complexity by abstraction


3.Remembering all the details


4.Communicating with other development team members


5.Communicating with a variety of users and stakeholders


6.Documenting what was done for future maintenance/enhancement

Stakeholders–

persons who have an interest in the successful implementation of the system

Internal Stakeholders

persons within the organization

External stakeholders

persons outside the organization

Operational stakeholders

persons who regularly interact with the system

Executive stakeholders

persons who don’t directly interact, but use the information or have financial interest

Workflow

sequence of processing steps that completely handles one business transaction or customer request

Activity Diagram–

describes user (or system) activities, the person who does each activity, and the sequential flow of these activities


1.Useful for showing a graphical model of a workflow


2.A UML diagram

question type

1.closed (predictable responses ex.facts)


2.open (non-predictable responses ex.opinion


3.Range of response(uses scale to assess opinion ---in fact ,closed )




key --avoid distortion

Alternative Model

functional Model ( shows what system can do)


structural Model(shows data structures)


Behavioral Model(shows time dependent behavior)

Information Gathering Techniques

1.Interviewing users and other stakeholders


2.Distributing and collecting questionnaires


3.Reviewing inputs, outputs, and documentation


4.Observing and documenting business procedures


5.Researching vendor solutions


6.Collecting active user comments and suggestions

Interviewing Users and Other Stakeholders

1.Prepare detailed questions


2.Meet with individuals or groups of users


3,Obtain and discuss answers to the questions


4.Document the answers


5.Follow up as needed in future meetings or interviews

A computer application

software program that executes on a computing device to carry out a specific function or set of related functions.

An information system

An information system is a set of interrelated computer components that collects,process,stores and provides as output the information needed to complete business tasks.

System Analysis

consists of those activities that enable a person to understand and specify what the new system should accomplish."understand"and"specify".

Systems design

consists of those activities that enable a person to describe in detail the system that solves the need.The operative word is "solve".

a project

a planned undertaking that has a beginning and an end, and that produces some definite result.

System Development Life Cycle(SDLC)

the entire process consisting of all the activities required to build, launch, and maintain an information system.

information systems development process

the actual approach used to develop a particular information system.

Agile Development

an information systems development process that emphasizes flexibility to anticipate new requirements during development.

iterative development

iterative development is an approach system development in which the sys-tem is "grown" in an almost organic fashion. Core components are developed first and then additional components are added.There is one big project, which consists of many mini-projects, and the information system is grown piece by piece.

A subsystem

A subsystem is an identifiable and partitioned portion of an overall system.

The Supplier Information subsystem

will collect and maintain information about the manufacturers or wholesales and the contract people that work for them.

The Product Information subsystem

will capture information about the various products, including detailed descriptions and photographs.

Planning process



Identify the tasks required for the iteration.


Organize and sequence these tasks into schedule.


Identify required resources(especially people)and assign people to tasks.

Work Breakdown Structure
