Chapter 3 Flashcards
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?
- Development/Installation
- Operation
- Enhancement, Replacement, or Termination
The Stakeholders in Systems Development Cycle
- Client
- for whom the project is being done
- pays for project
- has needs and requirements to be met - User/Customer
- operates or a beneficiary of project end-item
- might be the same as a customer - System Development Organisation (SDC)
- performs work for the customer
- aka developer, contractor, consultant
Describe what occurs during Phase A of the Systems Development Cycle
Phase A: CONCEPTION
- perceived need or problem
- initial screening or feasibility study; alternative solutions
- proposal
- concept approval or rejection
Describe what occurs during Phase B of the Systems Development Cycle
Phase B: DEFINITON
- specify requirements in detail: user requirements and system requirements
- define project to produce end-item/deliver requirements: project master plan
Describe what occurs during Phase C of the Systems Development Cycle
Phase C: EXECUTION
- design/development
- procurement/fabrication
- production/building
- installation
Describe what occurs during Phase D of the Systems Development Cycle
Phase D: OPERATION
- customer gains control
- system developer might remain involved through maintenance, enhancement or replacement
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?
- environment
- needs, symptoms, problem definition, and objectives
- prelim solutions and estimated costs
- benefits, strengths and weaknesses of each solution
- affected individuals and organisations
Decision Criteria to proceed with a project (occurs in Phase A)
- needs are real
- funding is available
- project is consistent with goals and resources of organisation
- project has priority with respect to other needs
- project has value (new technology, organisational reputation, market share, profit etc)
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:
- whether the competitors have a head start
- whether the SDO have funds and resources available to devote to a project
- value of project in terms of work reputation, profitability (i.e., is it worth it?)
- if the project is doable for the SDO
The contents of an Environmental Impact (EI) Statement
- summary of proposed development/management plans
- alternative sites and technologies for the proposed project
- description of the project’s existing site and surrounding area
- potential project impacts
- quality of air, soil, watersheds, wetlands, flood plains
- fisheries; sensitive plants; sensitive, endangered or threatened species
- scenic resources; societal and aesthetic experiences
- heritage resources (sites, structures, buildings)
- historical resources (logging, ranching, grazing) - adverse impacts that can’t be avoided
- long-term impacts on resources
- ways to prevent, minimise or offset impacts; ways to monitor actual impacts
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
- Executive summary
- Technical section (statement of work)
- Cost and payment section
- Legal section
- Management/Qualification section
Proposal must reflect the RFP
Should not be too detail; can use proposal as guide to do themselves
Executive Summary (in the proposal)
- more personal than the proposal
- states the contractor’s qualifications and experience
- draws attention to what makes the proposal unique, price, and the contractor’s ability to do the project
- identify contact person with the contractor
Technical Section - Statement of Work (in the proposal)
- scope of work and planned approach
- based on the work breakdown structure (WBS) –> Includes major project phases, key tasks, milestones, and reviews
- schedule (for deliverables)
- describe realistic benefits in detail
- recognise and discuss problems and limitations to approach
- specific
Cost and Payment Section (in the proposal)
- breakdown of projected hours, associated labour charges and material expenses
- addresses contractual arrangement (in terms of price) and method of payment
