Identify a Difference Between the Systems Development Life Cycle (SDLC)and

question 16

Multiple Choice

Identify a difference between the systems development life cycle (SDLC) and extreme programming (XP) .

• A)Systems development life cycle (SDLC)have a planning and analysis phase,whereas extreme programming (XP)combines both the phases into one phase.
• B)Developers following a systems development life cycle (SDLC)can move to any phase from the current phase,whereas in extreme programming (XP)developers cannot go on to the next phase until;the current phase is finished.
• C)In the systems development life cycle (SDLC)changes cannot be made to the system once it is delivered to the user,whereas extreme programming (XP)method delivers the system to the users and then make changes suggested by the user.
• D)Systems development life cycle (SDLC)develops the entire system at once,whereas extreme programming (XP)uses incremental steps to improve an information system's quality.

Definitions:

Aquifer

A body of permeable rock that can contain or transmit groundwater.

Groundwater Flow

The movement of water through the subsurface soil and rocks, primarily driven by gravity and pressure differences.

Permeability

Permeability is a measure of the ability of a porous material (such as rock or soil) to allow fluids to pass through it.

Perched Water

Groundwater that sits above the main water table and generally is underlain by a layer or lens of impermeable rock that blocks the downward flow of groundwater.
