Exam 10: Building Successful Information Systems

Why are intangible benefits difficult to quantify?

During the implementation phase of the systems development life cycle (SDLC),in _____,the old and new systems run simultaneously for a short time to ensure the new system works correctly.

How can tangible benefits of an information system be quantified?

Computer-aided systems engineering (CASE)tools are typically used during the _____ of the systems development life cycle (SDLC).

External users are normally part of a company's task force.

A _____ is a modeling tool used in structured systems analysis and design (SSAD)analysis model that helps break down a complex process into simpler,more manageable,and more understandable subprocesses.

List the different parts of the systems development life cycle's (SDLC)design phase.

Identify a key feature of extreme programming (XP).

During the planning phase of the systems development life cycle (SDLC),the systems designer must define the symptoms rather than the underlying problem.

Explain the concept of crowdsourcing.

State the five capabilities of computer-aided systems engineering (CASE)tools.

A(n)_________,which is a project management technique,can be established using the critical path to list the completion time of a project on the x-axis and all the activities on the y-axis.

Explain the four Ws that users must understand during the planning phase of the systems development life cycle (SDLC).

The fundamental principle behind _________ is that the "blocks of codes" can be reused in a variety of different applications,allowing new business processes to be created from a pool of existing services.

What is joint application design (JAD)?

The _________ approach treats process and data independently and is a sequential approach that requires completing the analysis before beginning the design of information systems.

Information system projects are often an extension of existing systems or involve replacing an old technology with a new one.

Why is the formation of a task force important?

Describe how information systems are implemented using a plunge conversion method.

_____ uses an iterative process that repeats the design,expansion,and testing steps as needed,based on feedback from users.
