Study Guide Exam for MIS 3320 FINAL
2024/2025
What is a system analyst?
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?
Framework that identifies all the activities required to research, build, deploy, and often maintain an
information system
Predictive approach
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
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
One phase begins when another phase completes; specifications are frozen problems; system
requirements locked in; limited user involvement
Modified waterfall
The modified waterfall allows for phases to overlap as well as the ability to go backwards; shortened
the development time - faster
Spiral model
Iterative approach; spiral until project completed then deploy; client is able to see something sooner;
multiple feasibility checkpoints
Incremental development
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
A guiding philosophy and set of guidelines for developing information systems in an unknown, rapidly
changing environment
Coupling
Qualitative measure of how closely the classes in a design class diagram are linked; strive for low level
Cohesion
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
comprehensive guideline to follow for completing every SDLC activity; describe everything the
developer needs to produce
Tools
Software to create models or other project components (record info to write code)
Techniques
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
Abstraction used to separate out aspect like diagrams (specify requirements)
Main purpose of analysis
Understand and specify what needs to be accomplished
Main purpose of design
defines and describes the system which solves the need
Scrum
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?
a time controlled mini-project that implements a specific portion of a system; scope cannot be
changed; usually 2 weeks
Scrum Master
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
client stakeholder who controls the product backlog; prioritizes it
Development Team
responsible for building the increment; 5 to 9 members with cross-functional skills; self-organizing
teams
What happened with the Project Leader role?
Scrums do not employ project managers because the development team is self organizing
