Purpose of phase is to:

  1. Study existing system & analyse findings.
  2. Will the benefit of solving the problem exceed costs of building system?

Tasks:

2.1 Understand the problem domain

2.2 Analyse problems & opportunities

2.3 Analyse business processes

2.4 Establish system improvement objectives

2.5 Update or refine the Project Plan

2.6 Communicate findings & recommendations

Feasibility Checkpoint: Go or NO-GO?

Participants:

  • System Owners
  • Project Managers
  • System Analysts
  • System Users

Deliverables:

  • A Set of System Improvement Objectives (grading criteria)

DO NOT define I/Ps, O/Ps or processes during this phase as further understanding of business problems is required.

Reference: SAD pg 82, 175

Purpose of phase:

  1. Is the problem worth looking at?
  2. If problem worth looking at, the following needs to be established …
    • Size & boundaries of project
    • Project vision
    • Constraints or limitations
    • Required project participants
    • Budget & Schedule

Tasks:

1.1 Identify baseline problems & opportunities

1.2 Negotiate baseline scope

1.3 Assess baseline project worthiness

1.4 Develop baseline schedule & budget

1.5 Communicate the Project Plan

Feasibility Checkpoint: Go or NO-GO?

Participants:

  • System Owners
  • Project Managers
  • System Analysts

Deliverables:

  • Problem Statement (PIECES Framework)
  • Scope Statement
  • Statement of Work

 

Reference: SAD pg 79, 167

The following 6 categories are useful for classifying problems, opportunities & directives (NOTE: Some problems may fall into multiple categories):

Performance

Information (& data)

Economics

Control (or security)

Efficiency (of people & processes)

Service (to customers, suppliers, partners, employees)

Reference: SAD pg 77

Framework for the

Application of

Systems

Thinking (representative systems development process).

FAST Phases are more detailsed than the classic phases:

  • Scope Definition
  • Problem Analysis
  • Requirements Analysis
  • Logical Design
  • Decision Analysis
  • Physical Design & Integration
  • Construction & Testing
  • Installation & Delivery

Reference: SAD pg 71, 79

Project Initiation

System Analysis

System Design

System Implementation

Reference: SAD pg 79

An Information Systems life cycle can be divided into two stages:

  • Systems Developement (Build system)
  • Systems Operation & Maintenance (Use & maintain system)

Two key events alters between the stages:

  • CONVERSION: triggers change from System Development to System Operation & Maintenance
  • OBSOLESCENE: triggers change from System Operation & Maintenance to System Development

Reference: SAD pg 71

Assesses the maturity level of an organisation

Level 1: INITIAL (inconsistent methods)

Level 2: REPEATABLE (consistent project management)

Level 3: DEFINED (consistent process used)

Level 4: MANAGED (process managed & measured)

Level 5: OPTIMISED (continuous process improvement)

Reference: SAD pg 69

Systems Analysis & Design methods are required for developing information systems for businesses.  In order to understand the processes fully, invest in the following book:

Systems Analysis & Design for the Global Enterprise 7th Edition

L.D. Bentley / J.L. Whitten

Published by McGraw-Hill/Irwin

ISBN-13: 978-0-07-110766-2

ISBN-10: 0-07-110766-5

I refer to this edition often & recommend it to anyone interested in focusing on Systems Analysis & Design.  It gives an overall picture & breaks the process down into easy to read chapters, identifying what stage the method refers to in the life cycle.

Welcome

The concept of this site was derived from assignments throughout my life as a Computing Systems student, where years of research required the one place for storage.   It is a “Go-To” site where some information is written as a step-by-step guide, while other data is used for quick referencing only.

Focus is mainly around:

  • Project Managment
  • Systems Analysis & Design and
  • Website Hosting & Maintenance

But also includes:

  • Multimedia & Web Development and
  • Hardware & Operating Systems

Harnessing YOUR Passion

It’s nice to see this site has helped people over the years & so I’m branching out & taking this further. I’ve always wanted to help others by harnessing their passion & utilise technology to work for them anywhere around the world at any hour of the day. Don’t you want to work ONLY TO FUND YOUR DREAMS?

In order to do that, we’ll be focused on people wanting to setup a website from start to finish with SiteRubix. It allows you to create beautiful websites in WordPress within the Wealthy Affiliate community. It’s honestly the BEST place to go if you’re looking at setting up your own business online. For more information, CLICK HERE. Basically you’ll be utilising Wealthy Affiliate (you’ll get two free websites) & CompuHint will focus on simplifying that training further in layman terms.

So if this site assists you to understand the concepts better or requires more refinement, do let me know, I’d love to hear from you!

Cheers
