what are the 4 types of Models
*Functional Model* - a structured representation of the functions (activities, actions, processes, operations) within the modeled system or subject area *State Machines* a mathematical model of computation used to design both computer programs and sequential logic circuits. It is conceived as an abstract machine that can be in one of a finite number of states *activity Diagrams* graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency *Use Cases* • a use case is a list of steps, typically defining interactions between a role (an "actor") and a system, to achieve a goal
What are the 4 types of systems engineering life cycles?
*Waterfall* a sequential design process, often used in software development processes, in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation, and Maintenance *Spiral* • a type of iterative system development model which is generally implemented in high risk projects *V-Model* • a graphical representation of the systems development lifecycle. It summarizes the main steps to be taken in conjunction with the corresponding deliverables within computerized system validation framework *Agile* • is a group of development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between selforganizing, cross-functional teams

What are the advantages to the Agile Development
-*Customer satisfaction by rapid, continuous delivery of useful software* -*Customer satisfaction by rapid, continuous delivery of useful software* -people and interactions emphasized rather than process and tools -software delivered frequently -face-to-face conversation -regular adaption to changing circumstances
Disadvantages to Spiral life Cycle Model:
-*Meeting budgetary and scheduling requirements is tough if this development process is followed* -cost is usually high -complicated approach -Rules and protocols must be followed closely -using the same prototype in future is difficult -amount of documentation needed makes complex
What are the advantages to the V life cycle model?
