What are the 4 phases of Systems Development Cycle or Project Life Cycle?
Phase A: Conception phase
Phase B: Definition phase
Phase C: Execution phase
Phase D: Operation phase
What is the System Life Cycle?
The Stakeholders in Systems Development Cycle
Describe what occurs during Phase A of the Systems Development Cycle
Phase A: CONCEPTION
Describe what occurs during Phase B of the Systems Development Cycle
Phase B: DEFINITON
Describe what occurs during Phase C of the Systems Development Cycle
Phase C: EXECUTION
Describe what occurs during Phase D of the Systems Development Cycle
Phase D: OPERATION
What is Phased Project Planning?
the stepwise fashion in which phases and stages in project life cycle are sometimes undertaken
Fast tracking in Phased Project Planning
Phases tend to overlap so work in successive phases happens simultaneously
Pro: Shorten project life span
Con: Increased risk of a mistake
What do you look into during the ‘initial investigation’ in Phase A?
Decision Criteria to proceed with a project (occurs in Phase A)
Feasibility assessment
the process of studying a need, problem, and solution in sufficient detail to determine if an idea is economically viable and worth developing
could be done in-house, or outsourced if specialised information is needed
When is a project viable?
if concept is something that customer can handle itself: if it is passed along to an internal group for development and execution
if concept cannot be executed internally: given to outside contractors (SDOs)
Steps in the feasibility study
1) Gain full understanding of user’s problem, need and current situation
2) Document current system –> systematic diagrams and summarise all information collected
3) Formulate alternative solutions
4) Analyse alternatives –> use models to assess the ability to meet user criteria
5) Include solution in proposal
6) Feasibility involves analysis of environmental impact
What is a Request for Proposal (RFP)?
A document sent by a customer to potential contractors explaining the problems, objectives and requirements
What is the purpose of a RFP?
Describes the customer’s needs, problems and ideas
Solicit suggestions/solutions from SDO
Inform how SDO should respond to RFP (where to sent, who, what to include)
What does a Request for Proposal (RFP) include?
1) Statement of work
- description of problem/need/general type of solutions to be investigated
- scope of work to be performed by the contractor
2) Proposal requirements
- conditions placed on the proposal such as proposal contents and format, submission deadline etc
3) Contractual provisions
- type of contract to be awarded, sample contract, nondisclosure provisions
4) Technical information or data
- any additional data necessary to develop a solution and prepare the proposal
5) Proposal evaluation criteria
- explanation of criteria and procedures for assessing the proposal and selecting a contractor
The SDOs decision to respond to the RFP depends on:
The contents of an Environmental Impact (EI) Statement
Purpose of project proposal
1) Sales
- SDO describes what they will do
- proposal needs to convince customer that the SDO will be their best option
- getting contracts depends on the proposal
2) Contract
- customer assumes that SDO will deliver what has been promised in the proposal
- if customer and SDO sign off, whatever is in the proposal must be delivered
Contents of a proposal
Proposal must reflect the RFP
Should not be too detail; can use proposal as guide to do themselves
Executive Summary (in the proposal)
Technical Section - Statement of Work (in the proposal)
Cost and Payment Section (in the proposal)
