What is the Software Development Life Cycle (SDLC)?
A systematic approach to system development which breaks down work into phases.
Phases include Planning, Analysis, Design, Implementation, and Maintenance.
What are the two stages of the system life cycle?
- Systems Development
- Systems Operation and Maintenance
This factors the lifetime of an information system.
Define System Development Methodology.
A formalized approach to the systems development process that defines a set of activities, methods, best practices, deliverables, and automated tools.
What is the main goal of the Planning Phase in the SDLC?
To propose a project, assess risk, and determine the needs for the project.
What is the focus of the Analysis Phase in the SDLC?
To define requirements for the system, evaluate alternatives, and prioritize requirements.
What is the purpose of the Design Phase in the SDLC?
To design the application and evaluate it based on the requirements identified in the Analysis Phase.
What happens during the Implementation Phase of the SDLC?
The system is integrated into its new environment and made operational.
What is the Maintenance Phase in the SDLC?
The ongoing support and updates for the system to fix bugs and improve functionality.
What is Scope Creep?
A common phenomenon where project requirements and expectations increase without regard to the impact on budget and schedule.
What does a Problem Statement/Definition entail?
A statement and categorization of problems, opportunities, and directives, including constraints and an initial vision for the solution.
How should a Scope Statement be structured?
It should improve [primary metric] from [baseline average] to [target] by [date] within [budget].
What are the components of Risk Exposure?
Likelihood/Probability of Risk Happening * Size of Loss.
True or False: The objective of Risk Management is to eliminate all risks.
False. The objective is to balance risk and reward tradeoff.
What is the purpose of a Risk Management Plan?
To identify, analyze, plan, monitor, and respond to risks throughout the project lifecycle.
What are the two extreme philosophies of physical design?
- Design by Specification
- Design by Prototyping.
What is Technical Feasibility?
Is the solution technically practical? Does our staff have the technical expertise to design and build this solution?
What is Economic Feasibility?
Should we build it? Determined by identifying costs and benefits of the project.
What is Organizational Feasibility?
If we build it, will they come? It assesses whether the system will be used.
Fill in the blank: _______ is the measure of how beneficial or practical an information system will be to an organization.
Feasibility.
What are Tangible Benefits?
Benefits that can be easily quantified.
What is the purpose of the Logical Design Phase?
To translate business user requirements into a system model that depicts only the business requirements.
What is Analysis Paralysis?
A condition in which excessive system modeling dramatically slows progress toward implementation.
What is the definition of Risk Monitoring?
The process of tracking identified risks and communicating the status of those risks.
What tools can be used for Risk Identification?
- Brainstorming
- SWOT Analysis
- Cause and Effect Diagrams.
