Cards

Term
As organizations’ reliance on software grows, so do the business-related consequences of software successes and failures including
Definition
Increase or decrease revenue
Repair or damage to brand reputation
Prevent or incur liabilities
Increase or decrease productivity
Term
Systems development life cycle (SDLC)
Definition
The overall process for developing information systems from planning and analysis through implementation and maintenance
Term
SDLC composed of 7 phases:
Definition
planning
analysis
design
development
testing
implementation
maintenance
Term
There are a number of different software development methodologies including
Definition
Waterfall (a sequence of phases in which the output of each phase becomes the input for the next)
Agile
Rapid application development (RAD)
Extreme programming-breaks project into 4 phases; cant continue to next phase until previous has been completed.
Rational unified process (RUP)-breaks down development into gates and either moves or gets cancelled
Scrum-produces small pieces of software using sprints to achieve a goal
Term
Iterative development
Definition
Consists of a series of tiny projects
Term
agile methodology
Definition
Agile methodology – Aims for customer satisfaction through early and continuous delivery of useful software components developed by an iterative process using the bare minimum requirements
Term
Rapid application development methodology
Definition
Emphasizes extensive user involvement in the rapid and evolutionary construction of working prototypes of a system to accelerate the systems development process
Term
prototype
Definition
A smaller-scale representation or working model of the users’ requirements or a proposed design for an information system.The prototype is an essential part of the analysis phase when using a RAD methodology
Term
primary reasons for project failure
Definition
Unclear or missing business requirements
Skipping SDLC phases
Failure to manage project scope
-Scope creep
-Feature creep
Failure to manage project plan
Changing technology
Term
consequences of failed projects include
Definition
Damaged brand
Lost goodwill
Dissolution of partnerships
Lost investment opportunities
Low morale
Term
Project
Definition
Temporary activities undertaken to create a unique product or service
Term
Project management
Definition
The application of knowledge, skills, tools, and techniques to project activities to meet project requirements
Term
Project manager
Definition
An individual who is an expert in project planning and management, defines and develops the project plan, and tracks the plan to ensure the project is completed on time and on budget
Term
Project deliverable
Definition
Any measurable, tangible, verifiable outcome, result, or item that is produced to complete a project or part of a project
Term
project milestone
Definition
Represents key dates when a certain group of activities must be performed
Term
the three primary and interdependent variables in any project (triple constraint)
Definition
time, scope and cost
Term
Project stakeholder
Definition
Individuals and organizations actively involved in the project or whose interests might be affected as a result of project execution or project completion
Term
Executive sponsor
Definition
The person or group who provides the financial resources for the project
Term
building a project plan involves two key components:
Definition
project charter-a doc't issued that someone has stepped up to pay for and support the project. project plan-a formal approved doc't that manages and controls project execution
Term
SMART criteria used for project objectives
Definition
specific, measurable, agreed upon, realistic, time frame
Term
a well-defined project plan should be:
Definition
Easy to understand and read
Communicated to all key participants
Appropriate to the project’s size, complexity, and criticality
Prepared by the team, rather than by the individual project manager
Term
Two primary diagrams used in project planning include
Definition
PERT and Gantt charts
Term
program evaluation and review technique (PERT)
Definition
a graphical network model that depicts a project's tasks and the relationships between them.
-dependency-logical relationship that exists b/w project tasks and a milestone
-critical path-shortest path ensuring all critical tasks are completed
Term
gantt chart
Definition
a simple bar chart that lists project tasks vertically agains the project's time frame, listed horizontally.
Term
A project manager must focus on managing three primary areas to ensure success
Definition
people, communications, change
