MIS 3320 FINAL - Sanchez
What is a system analyst? - ANS-responsible for the analysis and design of information
systems; translates a business problem into an information system solution; like an
architect
SDLC - what is it? - ANS-Framework that identifies all the activities required to
research, build, deploy, and often maintain an information system
Predictive approach - ANS-Requirements well understood and well defined, low
technical risk, can be planned in advance, system can be developed according to the
plan; Client knows what they want
Adaptive approach - ANS-Requirements and needs uncertain, high technical risk,
iterative, must be flexible and adapt (spiral model and iterative development); Client
does NOT know what they want
Waterfall model - ANS-One phase begins when another phase completes;
specifications are frozen problems; system requirements locked in; limited user
involvement
Modified waterfall - ANS-The modified waterfall allows for phases to overlap as well as
the ability to go backwards; shortened the development time - faster
Spiral model - ANS-Iterative approach; spiral until project completed then deploy; client
is able to see something sooner; multiple feasibility checkpoints
Incremental development - ANS-Iterative approach; system is built in small increments
and partially deployed in certain steps; as integration is completed, it is integrated to the
whole - some functionality gets into the user's hands much earlier
Agile Development - ANS-A guiding philosophy and set of guidelines for developing
information systems in an unknown, rapidly changing environment
Coupling - ANS-Qualitative measure of how closely the classes in a design class
diagram are linked; strive for low level
Cohesion - ANS-the consistency of the functions within a single class and is a
qualitative measure of its focus or unity of purpose; strive for high level
, Methodologies - ANS-comprehensive guideline to follow for completing every SDLC
activity; describe everything the developer needs to produce
Tools - ANS-Software to create models or other project components (record info to write
code)
Techniques - ANS-A collection of guidelines that specify a method for how to carry out a
development activity or task (how team will do the work)
Models - ANS-Abstraction used to separate out aspect like diagrams (specify
requirements)
Main purpose of analysis - ANS-Understand and specify what needs to be
accomplished
Main purpose of design - ANS-defines and describes the system which solves the need
Scrum - ANS-objective to be quick, agile, and intense at to go the entire distance.
Responsive to high changing dynamic environments (some projects never reach
completion)
What is a sprint? - ANS-a time controlled mini-project that implements a specific portion
of a system; scope cannot be changed; usually 2 weeks
Scrum Master - ANS-Scrum project manager - ensures the team follows the Scrum
process (a process owner not a product owner); a facilitator; removes impediments;
resolves issues
Product Owner - ANS-client stakeholder who controls the product backlog; prioritizes it
Development Team - ANS-responsible for building the increment; 5 to 9 members with
cross-functional skills; self-organizing teams
What happened with the Project Leader role? - ANS-Scrums do not employ project
managers because the development team is self organizing
Product Backlog - ANS-a prioritized list of user requirements used to choose work to be
done in a Scrum project; i.e. user stories
